In case you missed it at the very end of the video. We just announced our latest project startpropeller.com/. Propeller is an engineering recruitment platform that we created to share the most exciting and innovative jobs in engineering. Take a look at the jobs with our launch partners Hermeus, Relativity Space and Helion. If you don't see anything relevant be sure to sign up to our newsletter to get updated on engineering news and opportunities.
ok
I'm lazy so I hope you'll one day accept resumes and let the companies come to us instead. I know Hermeus at least uses the EDM that I work on, but I'd like to let the others know I exist too.
*or should I say I'm just satisfied with where I am, and thus lazy about a job search, but if I get an interesting offer then maybe
@@chunqk that is on the product road map
22:31 That diamond plume seems pretty familiar... ngl :D
Congratulations. What a cool project. Your years of work on TH-cam have made you THE GUY to do this. Massive respect. I hope Propeller is wildly successful, makes you wealthy, and helps tons of young engineers get stellar jobs. You're a scholar and a gentleman.
I only dream of being a hardware engineer, but I see there are already a few software jobs on there that I just might qualify for. VERY COOL!
My reason for No success in life: I have no basement.
Or a garage. You Have to have one or another.
You have to have a basement for your bullshit start up story to sell.
@@Steven_Edwards I have neither, nowhere to tinker 😞
I've managed to prototype & PoC on a bedroom.
You do have to be very good with resource management though, since you're effectively banned from using traditional tooling&manufacturing equipments in this environment.
It does make the challenge more harder, probably borderline impossible if you want to test a jet engine at the scale these guys are doing, but most likely viable on smaller scales.
I have come up with several billion dollar patent ideas sitting on the toilet in the morning. Does that count?
Getting some real "SR1-Normandy" vibes from this aircraft.
And heavy on the XB 70 Valkyrie layout inspiration for the air frame right down to the sonic shockwave riding wing tips
twin rudders fins etc ...

Was going to say the same thing!!
More like the SR2 since the first didn't have vertical stabilizers. Damn I'm a nerd.
@@spacewombat4569
I was going off the Airforce 1 design graphic... Sure enough XB70 pops up in the last furlong of the presentation.🧙♂️😎🇬🇧
In Skunk Works (the company that designed the U-2, SR-71, X-15, F-22, F-35, etc etc ad infinitum) engineers regularly went to work in overalls, because desks don't invent anything. It sounds like Hermeus is taking the same, time-proven tactic. Awesome to see.
I don't think you need to explain who skunkworks are on this page 😅
As long as they have recovered extraterrestrial craft
Not a company?
lmao Skunk Works isnt a company my guy its a Division of Lockheed Martin that use to be secret
@@moneybilla "lmao" oh, I'm so embarrassed I chose the wrong word! Whatever shall I do?!? Thank you, oh wise one, for laughing as you school my incorrect word choice! Almost as poor a choice as your "use to be", as opposed to the correct "used to be".
I used to be in the Canadian Airforce as an Avionics Tech. I'm currently going to to school for electrical engineering. This whole video and discussion about the work environment involving every member and aspect of the job is something I've been saying is needed when I was in the Airforce. This has been a very exciting video to watch while working on my Applied Physics Lab Report and Stats Assignment.
School is for fools; drop out and use street drugs. Find a stripper and marry her. Become a real estate mogul selling Canadian land to the Chinese, then become a Canadian politician and pass a bill disallowing foreigners from owning land in your country and give the land you sold to the Chinese to your business friends.
As a young aerospace engineer, the discussion about manufacturing at the end of the video was what sold me on the potential of this company. Being able to get up from your desk and talk with a machinist who will make your part or a technician who will handle it is what makes the difference between a project that goes from a blank sheet of paper to flight in 5 years and one that gets cancelled after 15 years of wasting money. The business case might be dubious, but with a great mindset and team like that building the aircraft will be no issue.
Completely agree
They probably will be able to make planes and then go bankrupt because no one wants hypersonic or supersonic airliners
Completely agree. I work in satellite production and design engineers were like bigfoot in our building. We actually relocated our testing labs to the same building to force them to walk through production
@@terrorstalker Design Engineer in aerospace and my company doesn't do it this way and its aggravating. I miss the smell of machining coolant
No kidding, probably the best mindset to have when your working on something that’s never been done before
"engineers are mathematically inclined artists" love that sentence!
Indeed we are, I couldn't agree any more or less.
Nikola Tesla did not use math . There is not a single mathematical equation associated with his work and he was starter of this age we live in . Without him we would be in dark ages still . So math is nothing , there is no math in universe , get in to nature and find math , chop up a part of your skin get it under microscope find math , get a telescope find math . Spend 2 to 3 years doing it and you will see like i saw , math is simplification of geometry , and in that simplification errors occur , where mathematicians them selves concluded using math that a complete mathematical system is impossible . Basic thing like Circle math is unable to show or calculate , circle let alone more complex things . Im not saying math is useless , no its a tool , but one should not obsess over it . Geometry is way more important , Geometry is in the pinnacle of scientific world not numbers , creation of new materials with new properties , done with geometry not with math . Large Hadron Collider LHC replaced with Wake filed accelerator that does the same thing but collage students made it with their own money, and it gave much better results . Scientific establishment is nothing different the Political Establishment , interested in money not research , god forbid invention .
So give respect where its due , Geometry
@@dedskin1 Geometry was the pillar of the Greek's way of doing math, but mathematics as a whole, not just geometry, is incredibly important and needed. Just look at JPEG 2000 (the jpeg picture format) if you need to see 1 everyday example of why advanced mathematics is beneficial. Every establishment will have politics, but most of the scientific establishment's constituents do not care about politics.
you love the sentence but couldnt be bothered to spell inclined correctly. American Educational Systems at work.
@@no1hereisahuman thanks for flagging. It's fixed.
Moved over to work at Relativity Space 6 months ago after 3 years at Tesla, and I’m genuinely so glad to see that your platform here on TH-cam is being used to broadcast such a great company to a larger audience.
It’s a wonderful place to work where the leadership really care about you and share the engineering drive that so many of us young engineers have.
Come build the future with us!

Damn, I didn't know you were chill like that 🤙🏻😛
I love the idea that Brian had a neuron activation moment the moment he saw a working Turboramjet. That’s some crazy technological advancement for a company like that.
Wait till you see me hold a piece of metal half way through the video😂
Lockheed would have had a supersonic airliner with turboramjets if it wasn't for politics. Much of the technology for that jet was coming from the SR-71
@@WolfeSaber9933and how much would it have cost ?
For most of its time the concord wast profitable
@@nikolaideianov5092 Well, its larger size and turboramjet engines, ones that could also make use of a high bypass duct for air, likely could have made it a bit more profitable. Maybe even as a supersonic cargo plane.
@@WolfeSaber9933Yeah like nikolai said: You can't cheat physics and if you double the speed you quadruple the air resistance so you have to burn 4x the fuel to get there and it just wont be cost effective for regular passengers.
I'm not an engineer, and a lot of these videos take me hours to get through because i'm always going down rabbit holes on other tabs googling things talked about to get a better understanding, but this is by far my favourite channel on youtube. Every time you release a video I get excited that my dinner is about to have some great entertainment to go with it. Thanks for everything you do!
I'm (nearly) an engineer and I respect you for going in the deep of it, it takes a lot of effort for an "outsider" and it's fscinating to see such devotion
I am an engineer and found a lot of this pedantic, unrealistic and designed primarily to encourage investment... "Make work"!
@MrMichaelFire , I've worked as an engineer in R&D for about 15 years. Your statement is ridiculous. We have a saying.
"Anything worth doing is worth doing poorly"
Quickly moving from a concept to prototype to learn and prove things out is extremely effective. It's basically why SpaceX can do 100x what NASA can do with the same funds.
tldr; they copied SR-71 tech and combined it with Japanese tech
You're an engineer at heart then, engineering is all about breaking jargon down into small understandable bits that you can digest, and over time build and literate on your knowledge.
As an engineer.... Hats off to you for developing a platform that focuses and prioritises companies that wants to allow engineers to do their job. Incredibly well said that so many get pigeon holed, and we know all too well about the advantages of putting the people qualified to make decisions into the decision making process - such a simple concept so many overlook!! All the best with the new platform, and thanks as always for such incredibly detailed, insightful and entertaining videos, keep up the great work 👌👌
I'm doing a final project work in civil engineering for UG and stumbling on different challenges and overcoming them is challenging and tiring. These guys are making an aeroplane engine within 6 months. Seeing them facing so many big issues but solving them along the way is very inspiring. This video encourages the "engineering spirit" within me.
That's the kind of company I want to work at. Talented, passionate, and driven individuals working towards a beautiful goal. Love the Propeller concept. We definitely need more focus like this.

The romance of supersonic flight easily captures the heart. But fuel costs per seat is the metric you will have to solve in order to capture the minds of airlines.
Nothing that I saw in this video impressed me, the ramjet technology and limitations of high temperature metallurgy go back to the 1950's (SR-71). Any piece of metal that reveals visually discernable voids is useless for any high stress purpose. So much of what this engineer talks about is speculative and unrealistic.. the greatest challenge to Mach 5 and faster flight in an atmosphere is extreme heating from air friction.. which makes metals brittle and fail. Elon Musk's Starship appears to be a far more viable solution for timely earth to earth transport.
@@MrMichaelFire In the first step they build a cheap testing platform to advance science. I think they are in early stages of development and will buy the most talented people with american military funding
Yeah, there are numerous good reasons why the Concorde model never really worked and why it wasn't tried again.
With only 4 seats, each ticket would have to cost $30k just to cover fuel & repairs. Or more.
@@MrMichaelFirecommenting so that I can come back when this succeeds in 10 years and you have to eat your words. 😂
love the conversation with tonio, im an engineering manager and designer at my company and we always are constantly going from engineering to the shop floor speaking with machinists to make the best parts possible. Its the only way to do it
What a genius move. Just through sheer views alone you're going to get tons of applicants, and high quality ones. That competition for the best applicants will incentivize people to do what they excel at.
It's literally "may the best man win and rightfully get paid the most".

I have a masters degree in mechanical engineering. In university I used to assist in teaching machining. When I got my first and still current job (17 years) after graduating I was unceremoniously booted out of the machine shop as I wasn't formally educated in machining and the technicians felt I was stealing their work. I just worked around it by switching to 3D printers and laser cut parts.
To maintain my skills and continue to grow them I gradually bought myself every tool needed to obtain all the fabrication skills I ever wanted in my home garage. No ideal but scratches that itch to build.
I have worked at both levels and hate it when they make that clear division in labor. The engineers need to experience the problems of machining and the machinists need to understand the problems that the engineers are trying to solve. Directly interfacing on a regular occasion is best. Have a tech look at plans before they are finalized. The designer should be present for the first build and visit often to see how the process has evolved.
I had in Germany day one for Engineers is a rat tail file. No equations no theory, a file. The importance of how the tools effect the materials is that important and is etched on to each engineers brain. Sure we can print a part, we can laser cut it. But what does it take to make the same part within thousands of an inch tolerances? Both worlds need to be understood and respected.
Now that I am old and understand literally everything (😂), it is truly a pretty decent sin to demand techs in front of machines exclusively and engineers behind desks exclusively. Also having massive software experience, my utter disdain for modern "programmers" is total garbage. All programmers should have to first write a kernel, then an OS, then a real time OS and a few RT device drivers. Anything less just means you are a literature major in the worst language ever devised by mankind. 😂
What's your salary after 17 years?
@@lefthookouchmcarm4520 Since you have no answer from the OP, mine ended at 200K after 40 years. It will be 300K if I take on any new clients, due to inflation.
As someone who's fixed J85 engines, it's astonishing to watch what is a relatively under-powered engine for modern times to something that could theoretically push high-mach speeds. Credit to their work, I wish them the best!
Just want to say I've loved your content for a long time and I wish nothing but the best for the team behind this channel.
What an honest dude accepting his shortcomings and methods of testing.
First, show that it's save as a commercial airliner.
after that, 10 years, Brandon Trump II ?
And yet “real engineering” wasn’t real in their marketing of this.
Can take a moment to appreciate the breathtaking 3d animations in this video. The turbojet at 11:50 made me audibly gasp.
Noticed the owner took it back quickly its a piece of copy writed tech I guess.
Love your curiosity, Brian! You're always the first person in the room to ask great questions no matter what! That's why I love Real Engineering videos; practically pulling the questions out of my own head well over half the time. It makes for the most informative videos out there! Keep up the awesome work.
I'm a Machinist - still an apprentice, but I have been in the trade for six years. That final bit about everyone working together from each discipline was so inspiring and true; I love that mentality.
Crazy to see the J85 engine put up against the F100 engine, the size difference is astonishing.
I really hope this company does well, ever since I learned in detail about the Concorde, I've been fascinated with supersonic travel and hypersonic challenges.
Also making your own site for engineers to find a job is such a cool idea, great way to use your influence as an educational platform!
Sorry to burst your bubble here buddy, but there’s a reason why the Concorde failed. The problems that made it fail back then still apply now. (especially considering this is hyper sonic)
I wonder if these would be possible on an even a smaller scale like TJ150 or some cheap COTS engine like Jetcat. I'd assume exhaust speed is not much higher on J85. If the exhaust jet speed after the afterburner (which you could easily add to Jetcat) is fast enough to get up to speed for ramjet to start working efficiently is the real question here. Precooling seems pretty straightforward considering you don't care about volume or weight for experimental purposes on the ground.
@@erinrizzo3004 And those reasons are fixable, like the sonic booms for example, we're developing aircraft that don't produce any, the economical crap will take a long time to iron out but it is possible.
A lot of the problems we just can’t fix, like how this thing will be astronomically more expensive and more maintenance intensive than any normal passenger jet. Considering how fastest this thing is going they will have to be long periods of time after landing to let the plane cool down from going hypersonic speeds. Nobody really wants to go on hypersonic planes because they’re too expensive for how small the seats are and people don’t find going that fast to be actually cost saving to them. Fuel prices will just be outrageous no matter how high you fly. Also flying that high like the sr71 means oxygen mask don’t work anymore so everybody has to wear a pressurized suit for safety reasons. Plus just hundreds of economic and engineering problems. @@RyzawaVT

Inconel being called "just steel" at 23:38 is pretty funny. I know it's a minor detail but it is mostly nickel and chromium, iron is a small percentage of the alloy. It's notoriously hard to machine, which is the reason why they are using additive processes to make a lot of these parts (as well as to make impossible geometries).
I caught that as well... I had already lost my respect for him as an engineer before that... "Just Steel" laughter ensues!
In general that was a very awkward couple of seconds of the engineer staring back and forth between the interviewer and the metal.
Don't most types of Inconel have the carbon content to count as low-alloy steel? or is the low iron content that makes it not a type of steel?
Its also a B!tch for forging processes. Extremely tough to form. And it takes a beating on our moulds. Just as a reference: we manufacture our moulds smaller by quite a bit just to account for the elastic deformation its subjected to during forging inconel.....
He’s a COO, I haven’t lookup his profile, but I suspect his background is not of metallurgy or material science. People overseeing things that’s not in the scope of their core skills, a common theme in early stage tech startups

Would you ever talk about apprenticeships for engineering and how great they are and how they allow for an engineer to get hands on work with a company while also getting their degree. Am currently on one myself, you were a large part of why I find the field so interesting so thank you, but id like to see your take on them an maybe even incorporating them into propeller as well?
4:12 Translation: The military industrial complex has the most money

Well duh. Military is one of the space where you can just write blank checks, due to importance, unlike consumer/automotive/industrial.
And even if they need a budget Air Force One, I hear you can get a pre-owned Boeing 737 Max really cheap.
Super cheap.
@@SnaketheJake87I'm thinking of getting one myself. It doesn't matter that I can't fly a plane because they crash anyway.
By far the best thing about the US Naval Academy's engineering program is the fact that our prototyping shop is in the basement, and every work order has to be viewed by both a faculty advisor, and a machinist before it is approved.
Good job editing out everything he was pointing to on his first engine. Very helpful.
I cannot stress enough how important it is for engineers to work with not only manufacturing, but the mechanics who maintain these vehicles. I’m an aviation mechanic working on Boeing 747s, 767s, and 757s. There are components we are required to replace that the engineers clearly never intended to be removed once leaving the factory. For example, the bracket of a thrust reverser blocker door requires that a mechanic squeeze his hand in between the T/R’s exterior translating cowl and the inner T/R composite wall. We have to remove two castle nuts that are cotter pinned with sealant over them while working blindly, i.e. by feel, in order to remove them. The process takes over two hours to accomplish once you know which tools to use. This challenge could have been solved quite easily by creating a small access panel on the translating cowl which would reduce the time for removal and installation from five hours to about 1.5 hours.

IMHO AF1 is a bit of a relic of the mid-20th century - although they have high-tech toys all over it. I'm pretty sure that somewhere in some top-secret hangar there's a stealth version of Air Force One, of course not as large. I'm just speculating but it makes sense. If/when the SHTF government and high-level military chain of command will need protection/speed/stealth. Air Force One has been a great airframe during peacetime but idk even with AF backup if it can do the job it was meant to do. Protect.
thank you for your incredibly educational series of videos about aviation engeneering. i learned so much and understood things, i believed to be out of my range to understand. i feel like your series has university quality. cheers!
The equation shown for drag at 38:20 is for incompressible flow because it assumes constant density. The statement that drag increases for higher velocities remains true, but after ~Mach 1 this is not the governing equation.

@@erinrizzo3004 Real Engineering put that there, not the company doing the engineering at this company.
Real Engineering also was super stoked on Nikola right before they went down
The part with Tonio Martinez is really cool for me. Because as you said, he's the one who's setting up the machine that builds the machine. I'm in logistics with 20 years experience, and the best jobs I've worked on are the ones where I can set up the processes from scratch. Working on integrating interdepartmental communication and processes, dividing up responsibilities and designing the hand-off procedures so that everyone has a set responsibilities that make sense but also where everyone is responsible for catching errors that occur. It's a very satisfying thing to do, and you can see that he both knows his stuff and appreciates the ability to do it his way
In fact.. really look at the sr-71. Even at it's time it was years ahead in design, airframe, engines, flight controls, engine cooling integration, just an awesome plane that if studied could be integrated with todays technology which could change commercial flight.
Interesting. I did my master's thesis analyzing a similar engine design/concept from a company called Limited Engines for a concept plane they called Skylon. So glad to see there are multiple companies trying to tackle this.
"Engineers are just mathematically inclined artists" beautifully said
Call it visual perception, NO degree required.
I love the way these guys bring high aeronautical theory and practical, efficient manufacturing solutions together - it's refreshing to see this kind of 'can-do'!
Becoming much more inter-disciplinary, collaborative in engineering practices is one way to ensure your ability to consider wider range of problems, wider reaching impacts.....also one way to transcend your job description on paper, become irreplaceable or much less replaceable by AI. I love this.
Was so so glad to see this video 😅 and I would love those working conditions/ parameters, I love collaborating with other tradespeople/engineers, I believe it 'drives' enginuity and innovation and makes any process better through communication, we work better together, unlike what a lot top heavy company's believe by keeping everything separate and compartmentalized
Air Force One is by defininion an Aircraft built for the comfort of the President, That means comfortable temperatures inside and the ability to communicate and navigate.
Irregardless of the altitude the aircraft skin temperature is close to
T = Tambient (1+ 0.2× M²)
Tambient ~ 250 K
M = 5
You finish the calculation
The calculation yields a skin temperature approaching the boiling point of salt. Not melting, boiling.
1500K is no joke.
The main issue is the sonic boom, many countries wont allow the boom, engine noise is another issue.
If they can get past those there are so many other problem, I would love to see a "new" concord, hearing the original come into Heathrow London every day was just fantastic. You could set you're watch by the noise.
There are others working on that, in particular the Lockheed X-59.
Even if they find a way to quiet down the sonic booms, there’s still a million other problems why this won’t work@@michaelmicek .
There’s a lot more main issues with this thing then just the sonic booms.
As soon as funding dries up this place will sell everything and be history
Fuel usage, noise. There's also most likely higher stresses on the machine, so it will need more check ups and maintenance. All of these are HUGE problems for commercial usage. Not to mention we are already clamping on CO2 and airplanes kinda get away since they are necessary thing we can't really do anything about. Overall, what we have seen is that lower fuel usage always wins, even if we don't take into account environment.
And I don't think rich people would switch from private jets to supersonic. Private jets allows for maximum flexibility, comfort and exclusivity, also time savings because you can skip whole hassle of airport. Supersonic passenger jet can only give speed, with possibly quite high restrictions due to noise and stuff.
Your videos are seriously worth our time, this is very interesting stuff, Real Engineering indeed. Thank you for this hard work 👌👌
Man 39:25 is so friggin true. I worked with an engineer who loved everything about engineering. He was constantly designing improvements to board layouts, power distribution, optics and a few other things. I had never seen him so disappointed when he went to a conference with his ideas and improvements and all the other engineers looked at him like he was nuts. Their response was "oh we don't really design any of that stuff, India and China do, we just get the parts and plug em in."
I love hearing about cool new things going on in the tech, transportation and EV space. It's undoubtedly the wave of not only the future but increasingly the present. I'm constantly posting all the latest in EV and tech news on my channel too.
good comment, I recommend this technology channel, it is the best
I agree with you sir.
In other words, the aircraft uses a conventional turbojet to accelerate to a high enough speed for a ramjet or scramjet to take over.
I'm a technology fanatic, I'm going to watch all your videos.
As a mechanical engineer this is what i live for. thank you
The next AF1 is going to be designed from a mass produced aircraft so parts will be readily available. Creating a bespoke aircraft like the one in the thumbnail is utterly infeasible.
5:00 - perfect example of how America/Americans talk poorly of weaker countries, but also don't want countries to be on their level. They therefore view counties either as leaches or as enemies.
Seeing the test environments made me realize I'd love to hear more about all the software related to it. Who makes the tools to process all that data and make the dashboards used to monitor the testing systems? Third party, in house? What does the tech stack looks like? Stuff like that. I know this channel is not related to software but if you could feed this lead to some friend who does that and let us know about it that'd be awesome!
“Engineers are just mathematically inclined artists.”
Thanks for this quote! It describes how I feel about being a engineer quite well.
The issue with forging large surface area parts isnt only the pressure. But the elasticity of the mold as well.
There is a point where more pressure is pretty much just transformed into the mold instead of the part.
Also, large surface area cools off more rapidly. Esp since the moulds can only operate at like 400°C before loosing their own material properties. Esp on slow hydraulic press forges thats an issue that leads to inproper filling of the mould.
Mechanical screw presses operate much faster, but are limited in pressure. Current max is like 35k tons. (2 presses exist. One in china, one in austria, both the same built by SMS)
There you can manage more complex shapes but you are limited in size.
3d printing it is a way better solution now. For high load parts forging might be necessary to enhance material properties.
Holy cow! I was already excited with the primary content of this one, but "Propeller!" I'm not an engineer, just an artist who loves aerospace! (SA43 Hammerhead is the GOAT) I'm beyond excited about your career forum for engineering! This is an Afterburner for Engineering! Fantastic!!!
Love the idea of startpropeller! Such a great initiative that makes perfect sense in this context!
You had me at “working turbo-ramjet” - I will be watching this with great interest
That young engineer has done very well in presenting the project, I bet he was bricking it about not releasing any of the real secrets, class video again, real engineering is a fitting name for sure!
I love what they had to say near the end about putting engineers in 'into the think of it'. I've worked for one of the big 3 car companies in the US for years and I can say they have the habit Martinez described. The Engineers that design the vehicles usually don't work in the same State let alone building, on the RARE occasions an engineer is allowed to actually come down and see the part they designed (Usually because of us line workers complaining to management about that faulty part for months on end) they're like a fish out of water, they have no idea about anything going on and seemingly walk out more confused then when they entered. I can't imagine how much money and time my company wastes because of this ridiculous model, and this is why we see companies created/run by engineers at the top run so smoothly. They know what it's like to try to solve a problem when nobodies aloud to talk to each other.
the president doesn't have to go anywhere in that short of a time period. It doesn't make any sense. IF anything, worst case the President needs airborne ENDURANCE.

business on the other hand would in many cases actually pay the premium bc the roi would be even greater
I think it would be cool to have a supersonic air force on one plane, however, I think the increased risks of hypersonic travel, especially in the near future, will mean that it'll be decades before there is one if one gets produced. Also Air Force One has to have an incredible amount of technology onboard for the President. That comes with so many issues, so I don't think it'll happen any time soon.
There’s million other reasons why this won’t work, even for passengers.
more importantly, the air force one flies with its motorcade. and while the president could fly hypersonic, lead time is still required bc hypersonic cargo flying is much harder bc of the larger volume needed
Some companies have inspiring mission statements: make life multi-planetary... accelerate sustainable energy. Hermeus' seems to be: keep America on top. Best to rebrand as Icarus.
It's nice to see some young talent in the US innovating! There's always so much negative news, and big media platforms don't show us this stuff. They prefer we stay divided.
As someone who's been to China many times. It's the future. We can definitely keep up and continue our progression in all things. As a proud American, it's unfortunate to see my country decline. In some areas, rapidly. It's the inevitable rise and fall of empires. Congrats on these guys' successes!
Even in the Soviet Union, such hypersonic civil aircraft were created. 40 years ago. The USSR was really developed in this area of technology. As a result, when the USSR collapsed, these aircraft stopped being produced, why? Because flying on such an airplane is 5 times faster, but the price is 10 or 15 times higher. Are you ready to fly 5 times faster, while paying $1000 instead of $100? (this is due to fuel consumption and greater wear and tear on aircraft at higher speeds; it’s hardly possible to think of any miracle that it will become cheaper)
it's never these companies' concern. the goal is to lure in the golden goose i.e. gov contracts and name their price funded by tax payers
are these hypersonic soviet civilian aircraft from 40 years ago in the room with us right now?
@@redapproves1330this is a rare company trying to not just rely on that. they have more in common with rocket lab tbh in their approach, and that itself gives me higher faith they'll actually pull it off.
rocket lab's ceo/founder was literally just a materials scientist and engineer. he had connections and some starting money, but you can get much of both just from working as an engineer for long enough.
No shot this ever gets certified.
I haven’t followed self driving for a long time and seeing this I got surprised. I really thought it would be better by now. People seem to think that “only a few” major faults in a couple of hours of driving is anywhere close to being acceptable. Some of these insane blunders seen in this video are so bad they would make my top 5 worst driving mistakes made in my last 15 years of driving.
A good driver can drive a whole life without hitting anything and people think it’s awesome that FSD would only hit a few things in a day
That building was used as a set for "Reacher", the series on Amazon.
One of the really great windfalls of doing huge projects like this is discovering, and possibly monetizing, the somewhat lesser initial solutions to problems encountered along the way to funnel back into the main project. I've been notorious in this aspect that occasionally some discoveries eclipse what I was trying to do that inevitably spiral into their own more lucrative projects. I suspect Hermeus will encounter the same in tackling such a sizable target where spinoff technologies will add an appreciable library of methods to other common problems to boost production of their own project, but also benefit a plethora of feeder industries.
The khaki pants and black t-shirt uniform the company employs is on point
The ultimate will be material science development of metal alloys that reduce drag by controlling the interface between the surface of the vehicle, and the atmosphere that is impacting that surface at high velocities--- the Teflon of supersonic flight.
The issue with getting a job in most the companies stated in the video like Relativity Space is that being an US citizen is a must and that unfortunately is a huge hit for us enthusiasts who'd dream to work in such companies who are not US citizens. I'd learnt this bitter truth last year when I visited stalls hosted by various aerospace companies at the Spaceport America Cup, most not able to provide internships to non-US citizens. 😢
Yeah, that has been the case for the weapons industry for ever
@@Michallote They have division for civilian aircraft’s too. There’s many other companies that make normal commercial products and yet can’t allow non US citizens.
I don't have a problem with the propulsion, I have a problem with it melting.
Aerogel, titanium, carbon fiber, etc. There are current ways to deal with the heating, better than the SR-71. Like fiber glass that was infused with aerogel took a flamethrower to it, and the guy on the other side, with his hand on the material, didn't feel a thing.
The hard part is incorporating all that into a lightweight design.
@@courageouslyencouraged Like aerogel
@@WolfeSaber9933Aerogel would make a terrible plane skin. It's incredibly brittle and fragile.
@@JohnSmith-sk7cg I talked about an infused substance. Also, there's graphene aerogel.
these are some breathtaking animations for something that sounds phenomenal
Its been very satisfying seeing this channel grow!
Lmao a faster jet is not at all comparable to the first great roads connecting countries and empires. We already have instant communication with the entire globe. It won't do shit for the GDP, and the fact that the dude from Hermeus was able to claim a 4 trillion $ increase with a straight face does not bode well. There is a use case in the military, but for consumer use it is an incredibly expensive toy for wealthy people... and akin to shoveling coal into a volcano when it comes to our sustainable aviation goals.
These videos need to spend more time on drawbacks and real metrics, not all company-fed propaganda.
100% agree. they move money like its not real
Thank you for not believing this bullshit man. I really enjoy it when somebody uses their brains here and just see all the flaws.
Agreed, this whole video was basically an ad.
Indeed lmao@@mullerstephan
Also, it is not China which developed high speed rail in the 20th century but Japan, China only started in the 21st. And the economic impact from that was from the fact that it is a mass transportation system, capable of moving millions of passengers, which will never be the case (in the short and medium term) for hypersonic flight.
You can’t fool me, that’s the Normandy! Hail to the Commander Shepard In Chief!
"I want to build a passenger plane"
"Cool. First can you help with our weapons of mass destruction and death?"
30:38 - Sounds like this guy actually knows what he's talking about. At least, enough to complete the mission. The scope may expand beyond his capacity. But, I believe that company will deliver the data needed to take the next steps. I doubt the company will exist in 15-20 years. I suspect the company will be dissolved into other, more established companies (i.e. bought out).
Let's start by upgrading Marine One. Not to a new prototype, just a newer anything that already exists.
The same reasons we are using an ancient Marine One are probably the reasons this monstrosity won't be used. People like what is understood and familiar even when outdated.
Yerp. No shot they’re putting POTUS on an unproven jet. Not that they didn’t test the jets, but time is ultimate test.
Marine One is always going to be a VTOL aircraft, so considerations have to be made for close quarters operation, ie White House lawn. It's already been "upgraded" to the V-22, but that has its own set of issues. A tilt rotor is the only way to increase the speed of a helicopter type aircraft, as there will always be a speed where a conventional helicopter will lose lift as the retreating blades stall.
@@The_Angry_Mediccounter rotating blades could help with that but they have there own problems
They’re probably going to replace it with a V-280 when they enter service.
New systems, even fleet deployed systems, still have unexpected behaviors and things that may not be completely understood until later on. Legacy systems might not be the newest or fastest, but with time comes design iteration --> reliability increase --> safety increase --> good for transporting the President.
0:33 you seem surprised these things exist? Lockheed SR-71 Blackbird (first flown in 1964, retired in 1989, 1998 & 1999) has 2.
I’m not trying to be mean, but I don’t see anything that impressive going on in this video. Some of the newest engine tech I see is over 30 years old
This just seems like vaporware to me too man@@K-Effect
They don’t fix any of the main problems about going hypersonic, they just provide a neat looking engine which if you get a couple dozen engineers and couple million dollars anybody can make something like that.
I thought this about a new Air Force One, ten minutes in and no mention of it. The UK had the Concord and we saw how that ended and why does the President need to travel at super sonic speed it's just not worth the cost.
@@Chestickles another problem i see with air force one being so fast, how can the jets that fly with it keep up with the president flying mach 5, surely they're not going to let the presidential aircraft fly alone
@@alexdubu9203 excellent point
Certification for A/C prototypes is difficult at best. Same with modern Vehicle Design. My last project concerned LIDAR for Autonomous Vehicles. Dealing with regulations during manufacturing is the cost driver. The point is. Breaking in to the industry can be prohibitively expensive because of regulations.
P.S. We had Hypersonic Missiles back in the 1950's. Think about it.
13:00 holy shit. That is one of the best explanations of the basics of a Ramjet in the whole internet. Awesome video
It’s completely not necessary. There’s zero need to have the president be somewhere far in two hours. Especially that it’s super small. The 747 Air Force one is the White House. You need to have the room to support all that logistics.
Imagine Biden moving at supersonic speed.
@@codetech5598uhhhmmmm... uhhhhh... mmmmhhhhhhh *crashes*
To be frank, any airplane that shuttles the president retains the call sign of Air Force One. The 747 may always be the best flying White House, but I doubt it will remain the only regular travel for the US President.
@@codetech5598he's gonna fall from the chairs
@@codetech5598 now that’s FUNNY as a hell right there!! 😆
Taylor Swift’s next private jet:
She’s on a mission to release as much toxic fumes into the atmosphere as possible
41:00 fly down fly down, mayday mayday!
jk, thanks for this awesome video man. I did miss the usual fancy graphics this time around, but lovely anyway.
By the time Boeing finishes their new Air Force Ones, Hermeus will have the hypersonic version ready.
Bombardier was an established Aircraft manufacturer with a great product with engines from an established engine company.
The problem was operators did not trust their long term viability.
Going fast in the atmosphere is extremely expensive.
I don't see how the economícs will work.
Good on them for trying. The romance of aviation catches a lot of dreamers.
The AirForce1 will remain a 747 for the sole reason that it has 4 engines. If a dual engine plane has an engine failure, it has to land as soon as possible. If a jumbo has an engine failure, it has to land as soon as practicable. Hence, it could continue to fly for a very long time, as they have in flight refueling capability.
Communication is critical to success. Disputes can be common between designers and builders (and leadership/stakeholders)
41:16 “Even tolerancing, you learn about tolerancing, but you never fully understand it until you see two parts not going together properly.”
Hermeus VP Production (and engineer badass) replies: “Precisely”.
What a great way to respond after discussing tolerance.
I’m looking forward to seeing what and where Hermeus goes from here. No doubt, wherever they go, it’s going to be fast.
The best starting location would be transportation of goods. It would get you off the ground sooner while still testing. The company wouldn't have to initially worry about meeting leisure travel safety measures.
I can't help but think that a compound engine, allowing for both types to the active at the same time during the Rams startup would be preferable no slowdown needed.
Very cool! Thank you for making this!
RE: the kid sounded nervous but he knew his stuff - i think you should give him the job. 😄
This video is absolutely amazing 🤩 thanks a million ❤
It is suggested that the primary objective for generating revenue initially is to establish an in-flight testing platform for companies that are developing technologies in the hypersonic range.
At the same time, the development aim is for an aircraft to operate at lower hypersonic velocities.
Is that not contradictory as the use of the testing platform is limited?
whats missing about the speed is that speed has been offset by scale and cost - so container ships slow steaming but larger, 747-A380 vs Concorde. Even HSR rail trades speed for the cost of the rail infrastructure. At the same time the Supersonic Jets seem to be able to use existing jet engines and generate supersonic speeds without needing the military to offset the R&D cost.
I noticed his Casio calculator watch at 23:31. If that doesn’t mark a true engineer idk what does. I can’t wait to see what Hermeus puts out, they seem leaps and bounds ahead of the competition right now.
The J58 (SR-71 engine) was NOT a ramjet. It never fully bypassed the turbo-machinery of the turbojet. Above Mach 2 it diverted 25% of the mass flow directly to the afterburner so you could call it a pseudo-ramjet.
Regarding The conversation with the engineer, I wonder if the reason other companies separate the departments into separate buildings and many don’t know what the project is developing, is because they don’t’t want secrets known to every department, thus increasing the chances of other companies getting their secret discoveries
