- In this video we will be looking at Jetoptera's Bladeless Propulsion System that utilizes fluid induction.
There are several advantages of doing this specially in conjunction with boxwings.
At present Fluidics propulsion system will utilize GE aviation gas turbine but it can use an electric turbine as well. - วิทยาศาสตร์และเทคโนโลยี
Interesting concept, I wonder if this could be applied to boats, with an electric fan. I’m thinking particularly to the small dingy and kayak/ trolling sectors where hands and animals proliferate.
That is actually a very good idea. I am sure people looking at submarine propulsion would be extremely interested and even boats
Good question about boats.
another thing to look into is how large ships also pump air under themselves to reduce drag, could be really interesting
Also for a kayak you could probably test it with a 3d-printed set of parts, would love to see that become a reality
Pump-jet on watercraft have quite a few similarities.
Tom Clancy wrote about such a submarine drive in The Hunt for Red October, in the 80's.
It will be interesting to see how the thrust-to-weight ratio works out for the full-scale, manned and fully-equipped aircraft.
In other words you want your fat mother in law to be a test pilot just to make sure lighter loads can be carried with a HUGE margin of safety ?
@@WilliamRNicholsonLST-1195 As the old saying goes: better safe than sorry.
I proudly state that I am Old School and reject the new-fangled 'Risk Assessment' approach for the tried & true 'Risk Avoidance' approach.
This might make an interesting motorcycle drive system. Very inexpensive compared to a geared system.
@@pauld6967 Watching the 6 month planned Inspiration4, which set numerous records for humanity, implemented quite a few large-scale never-done-before changes... like the Cupola in place of docking capabilities, gave me a new found respect for the modern way.
@@pauld6967 lmao what are you talking about?
Firstly, risk assessment and risk avoidance are fundamentally the same, they avoid unnecessary risk. Secondly, there's no reason for safety to not progress on the principal of clinging to obsolete tradition.
You're welcome to stay in the past if you want to, that comes at the expense of innovation and progress. The rest of the world will be just fine moving on without you.
It's always weird to see someone who would rather kneecap themselves over tradition that has little to no value. Pride is a strange thing.
Thank you for this very well made short documentary on this vehicle. It's a beautiful craft and I hope it becomes a reality. I think it's my favorite design for a personal flying machine so far.
Glad you enjoyed it!
Saint Rutan watches over all canard aircraft. 🙏🏻
I'm with you,this is the best looking personal craft I have seen so far. Would love to do the test flight in it.
THIS GUY IS SO SO SMART HE CAN EXSPLAIN TO PEOPLE HOW STUFF WORKS THAT ARNT AS EDUUCATED AS ENGINEERS THAT TAKES INTELLIGENCE
Exactly - we all have different speeds and styles of learning. Simplest is always best - for everyone.
You explain this so well, I'm rooting for them to succeed!
Basically Dyson-Ventilators and Hairdryers as a Propulsion-System, a lot safer for Birds and IndianaJones' Villains.
Exactly, That's the basics, they just use wordplay.
yeah they dont have to worry about getting shredded by a propeller blade but still have to worry about getting hit by a plane going 300 mph
@@mason2699 I would guess that the forces of going though would lead to death..
Birds would probably be ripped apart by the high pressure air. Also the compressor needs some kind of intake.
So more ducted fans using bypass air. Nothing new under the sun.
I just found your channel yesterday & I'm EXTREMELY IMPRESSED with the amount of technical knowledge you're able to squeeze into a 10 -20 minute presentation. I hope you'll be coming out with new material soon because I'm almost through all of your videos, lol.
Keep up the outstanding work please...
Welcome aboard! and thank you son much. With the amount of research that goes into every video, its difficult for me to churn them out every week. I can do videos every fortnight
I love the idea of using drones to scale up to a full size model. Reminds me of the movie flight of the Phoenix. A model airplane engineer is still accountable for all the same Elements for flight, same as a full size plane. Great work and I’d love to ride in one soon.
It seems that certification for human flight is super difficullt. There has been quite a few flying taxi projects. So far none has been granted human flight certification. None even from China, Dubai or Singapore. It has a long long road ahead.
@@catchnkill sounds like a conspiracy..."big air" is keeping us in a tube with the masses. 😆
Beautiful design using current technology and improving it. The narrator’s description of how it works creates a want to learn more.
Great video and well written. This tech is something totally new to me and I've been in the biz quite a while. I'd love to see more videos on detailed thruster fluidics and other applications.
You're a very good presenter. Took an interesting but complex subject, and really broke it down into something really understandable. Great video my dude! :)
Lol. Are you saying that to make him feel better about his thick Indian accent that is hard to understand?
It was also used in aerospace technology as a thrust augmentor, drawing outside air into the rocket exhaust gas stream, cooling and condensing the flow, increasing the mass, and exponentially improving the propulsion efficiency
I’m strapping a few Dyson hairdryers on my belt, just watch me fly
Let me know if that idea takes off. 😁
Spinny you are a sick puppy ,let me know if it works
YA, I'm looking at my Dyson fan right now, cool beans
I'm only here to see if I can use this tech on my eboard.
@Muckin 4on haha
Your not working fancy electronic crap nearly burnt your house down
3 phase brushless motors should be ancient and I am also amazed that a Chinese company hasn't......
Bernoulli's ghost nods and smiles
i would have thought coanda.
coandah worked on the outside.. Bernouli worked inside a manifold.. but they are the same ideas derived from observations.. and measurements.. science is all about measuring the Universe we live in.. if you don't see the math It's not science.. ...
now.. think about a personal sized dirigible.. can land anywhere, even water.. with solar cells printed on the skin.. and a neutral buoyancy from helium... with palladium instead of aluminum.. it's almost impossible to melt as AuPd.. lighter than aluminum.. stronger than steel... steel has a density of 7.7.. palladium starts as 8.8.. it's like plastic steel.. mixed with gold... and it is definitely lighter than aluminum and I am not sure how .. it's a measurable phenomenon that happens each time I make AuPd
it's not rare or hard to find... it's going to Change the World
first up.. palladium foil 1m³ helium balloons .. many.. and a 7.5 m² parachute to hold them together.. silk and shellac create a very strong bio plastic for the outside... and.. the pilot seat.. to see what happens... I am working on it now
Jet Octera is really a great invention over the centuries.I believe it will build a highly technical change in Aircraft Aviation in coming days.Bravo !!!
Propulsion and laminar flow are the keys to success here. Wishing them lots of success in further development and scaling up of this concept that promises 50 percent less fuel!
Laminar flow were used for some WW2 fighters so...
How can you have laminar flow when you need highly compress air jet mixing with ambient air to generate flow induction? This is nonsense they are just stringing together buzzwords to fool investors.
@David S. both laminar flow and turbulators were developed simultaneously. Both seem to have dropped into the background
Thank you for the very clear explanation of the engineering involved in this craft. I'm just a layman and this video kept me captivated from beginning to end! Beautiful craft. I do wish this company much success with it! Reminded me of Bladerunner!
You are very welcome
Beautiful and passionate. You are a good speaker, sir. Your love of the subject shines through.
Thank you kindly!
Haha!!!
Great video, I look forward to hearing more about this concept. The idea of a more simple VITOL craft is needed. The viability of the small electric craft makes it quite interesting and makes it more financially viable. I really hope this development works.
It is easy for those with a negative mind to sit there and say it won't work, but developers like this need as much encouragement as possible......
Keep going Jetoptera!
Exceptional video! I've never seen this channel until today, but was elated to find that although you have an accent the content was very good. I've seen people with accents believe they can never do things like TH-cam because of it, but I think videos like yours are proof that it's all about the quality of the content.
Duh...
We all have accents. Why couldn't he be successful?
My favorite aspect of this video is how you broke down and explained the technology. Very well done! Thank you!
Glad you enjoyed it!
As a sub contract industrial designer in Calgary I had a brief pleasure of working on a few components of Apteras electric car. It also uses Laminar surface tech, The look is very much of the same designers so I'm betting heavily its the same visionaries. Congratulations and I hope your strategy for business gets you there faster, into your rightful place in history. First place conceptually.
I watched that other guy market his "flying car" for a few decades. I always laughed at it because it was basically a helicopter. This design is actually innovative and gives me cause for optimism. I wouldn't call it a "flying car" because it doesn't look at all suitable for driving around town. But as a door-to-door mode of long-distance travel it looks to be phenomenal. It would give me the ability to randomly visit family 900 miles away without the need for planning, taking time off work, or dealing with airports.
its still an aircraft so you would have to plan and deal with airports and controlled airspaces
Simple and elegant... hopefully it will work and come to market soon. That bladeless propulsion looks like magic to me. What amazing minds to discover this technology. BRILLIANT!
me too. Especially if the thing does not run on electricity and does not need it at all.
He showed similarities between a Copus blower and Henri Coanda's air foil aircraft design, to this design. both operate similar to how the Dyson blower works. Copus blowers have been used for years for confined tank enclosures and for drying or cooling inside of tanks. We used ours to cool down the shaft furnace at our copper refinery just before a furnace rebuild.
Самолёт команды не взлетел проще говоря такого самолёта не существует
This same principle is used by some camping beds and beach couches where you gently blow into the inflation tube which is specially designed to multiply the air, and it blows up the whole couch.
Your breath creates a pressure difference and a flow which pulls in the surrounding air to fill the entire thing with very few breaths. Pretty cool.
That’s just a simple way to see this principle in action with your hands and your own breath. It’s pretty magical when b you see it work! One breath and the bed is almost full! It’s pretty crazy… science is awesome
It works the same on my blow up doll
An excellent description of fluidics, very clear. I share your hope that we will see this vehicle put into production.
I hope so too!
Sublime combination of form with function. Beautiful alternative to bladed drones. Dyson should sponsor this magnificent craft.
Too bad it doesn't work as described.
It's nice too see them doing what I had wondered about. Using 'blade-less' lifter engines. I think they will stand well for low velocity cruiser aircraft.
Your explanation of the principle of operation of this aircraft is underrated, keep up the good work
I'd like to see the calculations for their propulsive efficiency. There may be an augmentation effect (similar to ejector pumps as you pointed out) but the efficiency of the gas generator must also be factored in.
I LIKE TO SEE MORE OF THIS JETOPTERA'S BLADELESS PROPULSION SYSTEMS!
then you should do more research on it or work for the company
USING AS MANY CAPITAL LETTERS IN YOUR COMMENTS ALWAYS HELPS YOU GET WHAT YOU WANT. ADDING AN EXCLAMATION MARK WAS A NICE TOUCH TOO! WAY TO GO!
Or watch that guy the fly with 4 of this engines attached to his hands which btw weights 10x times more thant a paper plane .. lol research

Without question, this technology will revolutionize every day travel. Wishing you great success with this project. Hopefully in the near future people will be transported using a clean, non carbon based furel systems.
Unless I am mistaken the entrainment function merely uses a small high speed stream to accelerate a larger low speed stream, but it does not create any additional thrust. It is hard to see how this could be more efficient than a propelller driven plane, as the propeller directly creates a low speed stream without needing to accelerate the air around it.
That's why they cleverly don't claim that.
If you listen carefully they claim to be superior to small jets system. I imagine it's pointing to small ducted fans like E-fan airbus electric plane, or small turbo jets.
Not propellers.
The entrainment causes more flow around the motor so more lift for the box.
I think it's a good compromise of compacity and efficiency and safety against multirotors or tilting multirotor + small wings.
Maybe sometime someone makes this effect into the wing itself so the whole surface is both propulsion and lift. Also this plane has a rather small intake at the top, this might be the limiting factor for its total power.
Actually, entrainment experiments 100 years ago in Scotland using solid rockets to give the core gas stream, showed a thrust amplification of around ten. The idea is to tailor the exit speed of the mixed flow so that it leaves the rear of the aircraft at exactly the same speed that the aircraft is moving forward: thus, the exiting flow leaves with zero speed relative to the atmosphere so has zero wasted kinetic energy remaining in the exhaust. Ergo, big improvement in efficiency.
@@richardm.newlands2417 is that related to aerospikes? But also that would work only for cruising speed not acceleration.
@@richardm.newlands2417 If the exhaust has zero airspeed as it leaves it will also have zero thrust!
This is an absolutely brilliant concept I really hope they can get this thing going with a full scale mock-up
I think this is an amazing exercise in thought and I wish them all the luck. The design is very close to what I am trying to accomplish myself. I am very excited to watch their progress and very thankful that the time and money isn't mine wasted in this pursuit. I almost certainly guarantee that they will find that these principles do not apply and are very ineffective at scale to lift something vertically like a passenger vtol. But that being said I pray I am incorrect. And if anyone reading this associated with this project I would be interested in offering my game changing energy storage systems.
One huge advantage of this concept for application to flying cars and urban air mobility is the lack of exposed rotors/propellers. Designs like the Ehang 216, for example, feature exposed rotors that are hazardous to life and limb, limiting flexibility for boarding, and operations around people.
F4E Phantom used blown leading edge flaps. Lowered take off and landing speed by 15-20 kts. Used lots of compressed air but J79 had plenty to serve up.
shinmawa US2 stol seaplane , also uses a turbine for force assist flow over flaps ,
Those systems were low airspeed lift augmentation designs and horribly inefficient. They did their job, though.
Jet of terror, it needs a better name.
And the comments sections are invaluable no matter the topic. hearing from people all over the world from every background and education level is a big part of the Internet experience.
It's like a cross between a Hawker Siddeley Harrier and the Red Baron's Triplane!
This is one of the coolest videos I have ever watched on TH-cam...
So I take it you have never seen many youtube videos
Thanks, your explanations are clear and easy to follow without being handwavy
This is super cool, I'm really rooting for them
Lol 'Rooting' in Australian English has a VERY different meaning!

It's a fake
@@ronaldharris6569 Fake is a bit rough; I'd say mock up. The only thing visibly flying well is the model powered by ducted fans.
just as concept.
@Jimmy Bond lol? its a known effect and there are tons on solutions using it. but it wasts energy son in general its complicated and pointless. but there are a lot of devices like that/ look at any iphone)
Fascinating, promising concept brilliantly presented. Thanks for the info!
This is an *EXCELLENT* channel. I must say, your english is outstanding brother. Also, i can appreciate the way you explain things accurately with a minimal amount of words, making it even more easy to understand.
*subscribed* upon hearing about 4.5 minutes of this video.

I appreciate that!
Great presentation. I learned a lot from your video. For the technology itself, this is huge. It looks to me like a future of flying.
This video should be sent to all STEM schools. The WOW factor could inspire students to study physics and a variety of engineering subjects.
@@bikebrains another person posed the idea of making a smaller bladeless system for a boat, imagine a bunch of STEM students designing, printing and using a system like that on a kayak via 3d printing.
@@bikebrains To learn how not to do it?
These thrusters rely on turbulent mixing of the driving jet with the secondary airflow. They can not enhance thrust over the entire flight regime - maybe they can enhance static thrust. I am sceptic.
it is supposedly meant to increase lift on the wings... at least that's what it looks like to me.
Just a picky note: you meant "skeptic". Sceptic means a blood infection.
@@2degucitas maybe thats what he meant, maybe he has a blood infection
I am a sceptic :-) but not septic. Sceptical I get,
when I hear the sound of jet pumps turned inside out....
@@doctor_moodm9536 Which makes the cartoon of using them as VTOL lifters dodgy.
A concept that may become a landmark to aviation. Interesting. Keep it up.
In these VTOL 'demonstrations', did they actually match the scaled weight and weight distribution modeled for a unit equipped with a gas turbine and fuel against the scale adjusted thrust expected from said turbine system?
Because I can strap a single LiPo battery and enough high power ducted electric fans to a toilet, and burn through the LiPo's power to get it in the air for 20 seconds, but that doesn't mean a toilet is a valid aircraft, jet engine or not.
Often "startup" companies do just that. Feed you some serious 'crap' while getting a crap idea to partially demonstrate, then fleece dumb investors, flounder, and act like they don't know what happened with the 'new technology' not working out. Oh yeah, all while the founders make millions on failed ideas.
Sounds like a crappy way to travel.
@@life_of_riley88 And fanboys keep drumming the thing further. Like with this video, hey look electric flying car! It can easily be made electric... when battery technology advances further.. so not in several decades and i would be even less interested in this flying coffin than EV, since with EV you wont probably... maybe die when batteries crap out.. with this yeah no.. With jet engine this might have some sense, but vtol is always hard thing to build since you need lots of computers to assist even professional pilot.. One computer crapping out can easily lead disaster with vtol. Also as mentioned duckted fans are now flying the test platform, but we have no idea what ever this actually works in real world aircraft and will it be powerful and practical enough. Its interesting concept, just hate how EV fanboys start drumming for shit like this, even before there is model version flying and even then scaled weight of the aircraft seems to be forgotten on test for looks of it.
@@life_of_riley88 Tesla being one of the best modern examples of this lmao
@@Hellsong89 What do you mean "like with this video"? The video is fairly informational and doesn't act like the technology is right around the corner. The guy isn't drumming anything up.
I get how annoying the current tech climate is with people like Musk and his cult but that doesn't make it a good idea to take the polar opposite stance.
Yes, the technology is being looked into. That's all the video really says while breaking it down into examples how how the tech is used today as well as proofs of concept in the past. Nothing wrong with taking a look at previously mothballed technology with a fresh pair of eyes as long as no one's being conned, which this video doesn't appear to be attempting to do.
this channel is so well researched. great to watch
Much appreciated!
What !!!!
You may invent the first subsonic ramjet engine if you keep experimenting like that!
Very elegant design. You are onto something, I am sure.
Then there is the shark-eat-shark world of business! I wish you well Sir. 🙏
So where can I invest in this unproven tech based on a novelty fan? Cause flying cars are a good idea.
😏
flying cars are a terrible idea: the sky will soon be as overcrowded as the roads are now.
we need flying busses, trains,...
@@darkswami Lol its crowded because you are limited to roads. No lanes in the sky...
Flying cars have existed for over 100 years. They are called airplanes.
@@darkswami flying busses already crowd the skies. They are called jumbo jets
"bladeless" - except for all the blades in the compressor feeding this system..........It seems nobody ever learns from history. The Americans and Canadians found that the "coanda effect" doesn't scale up to aircraft size after spending millions of dollars.
60 years ago - maybe they have solved the issues.
@@daviddesjardins7751 those guys 60 years ago pretty much reached the physical limits of what is possible in regards to jets.
What are you talking about? I’m interested in learning. (:
The Avro Car? the US took it all from Avro and it went black so we on't know where it ended up.
this IS coanda effect obviously, and im NOT seeing any benefit from this particular configuration.
If it was integrated into the wing chord for added lift it would make more sense.
What an exciting concept! I'm not so impressed with most TH-cam videos. Thank you so much. One small point: the plural of aircraft is aircraft.
Thank you. I have since corrected that mistake in my subsequent videos
This is the 'cleanest' propulsion system I've seen. The e-aircraft with zillions of often vertical facing 'propellers' simply look chaotic. And each propellor unit needs a motor thus upping the cost and potential reliability. This system, on the other hand, is relatively simple, and, I've read, quiet. It looks much better than the Cityhawk thing too. I hope it gets made.
Needs lots of investors
Nice video! It would be interesting to see how performance changes with altitude.
Thank you for showing how the Dyson fan works! Always wondered how they did that. This Fluidic propulsion is such an elegant solution for aircraft. Why not power the craft with the very air it flies through? Genius 👍
doesn't work.
I'd love to see what this type of propulsion could do wrapped around a blimps mid section
turtleairships has the same interest in the potential.....
I would be more interested in ridged airship applications, although without wings they would operate as thrusters. Perhaps an azipod for dirigibles ?
Do you mean the whole surface could propel it? Nice idea
Supersonic stealth blimp confirmed!
@@635574 Yep going with your average football shaped blimp with a large propulsion ring right around the mid section, or perhaps slightly toward the back to reduce drag. Would love to see how it performs in a computer simulation
That is too cool! I bet it's going to be extremely quiet compared to a standard jet engine. And you're really good at explaining it all. You've got a new subscriber
Dyson bladeless fans are louder than cheap fans.
Dyson claims 60-70% nose reduction for their fans vs. Blades
@@myotherusername9224 at minimum speed vs blade fans at maximum. When full fledged they're noisy AF and don't even blow that much air
Ever since I first heard of the Dyson “bladeless” fan (and its offshoots) this concept has fascinated me. It’s nice to see it’s fuller potential being developed. My very first thought at the time, however, was, “As it works with air,shouldn’t it also work with water?” I mean … submarines!
Dyson isnt bladeless the turbine blades are inside the base.
@@itsalllies4102 < Agreed. That’s what the quotation marks were for
.
I'm interested to know how exactly entaining more air through the rear cowl actually results in more thrust, or even more air flow over the wings, since it looks like the air will be entrained through the cowl father than around it, and any air flow at the back looks like it will be behind the wings altogether.
One reason is that the wings can be laminar flow with no engine cowlings interfering with airflow over the surfaces, in addition the intake of air increases the flow over the wings, creating more lift.
@@scotthill2230 but how does the intake increase the air over the wings? I would get it if the cowl inlet started behind the wings, or if it finished in front of the wings, but I really can't see how its meant to be moving any more over the wings at all.
@@benwilms3942 Wouldn't the accelerated air that's rushing back create an area of lower air pressure in front of the cowl causing the air in front to get sucked in and accelerate over the wings in the process?
@@bokiNYC im not sure I follow, if the air is moving into the cowl, then I can't see the connection with air moving over the wings.
@@benwilms3942 The thrust provides forward movement, which in turn provides faster and faster flow of air over the wing as the ground/air speed increases. The wings themselves passively provide lift by virtue of their shape. Therefore it matters not what airflow is produced behind the wings by entrainment, other than to provide thrust for forward movement.
The box wing concept was used in the Synergy aircraft design that looked promising a few years ago, but its development doesn't seem to have gone anywhere recently. Hopefully the Jetoptera design will be able to take this idea forward to something realisable at full scale.
Yes, I keep looking for progress on the Synergy. From what I can tell, it's a father and sons endeavor.
This is absolutely AMAZING.
We are living in incredible times.
We are looking at this technology I'm sure the way the wright brothers looked at the technology they crafted.
I'm so excited to see the future. 👍👍
I love this so much. I'm stoked to have found your channel!
I'm genuinely surprised at the quality of the video, great job!
I have been flying Electric RC, planes, both propeller and ducted Jets, Helicopter’s for about 20 years. My buddy Matt flys Turbine jets. Very fast and cool, but the cost is way more than I would like to afford. This is very interesting, subbing.
In fact, this is a type of ejector. Ejector's efficiency is poor. And with high passive flow to active flow ratio it is poor twice.
poor twice sounds like my financial condition
But.... don't 2 negatives make a positive? 🤣🤣
@@rosebarnes9625 twice is a positive number.
@@eeeeeek all changes :-)
Brandon Furr only the constant twice is positive the other variable is negative.
i was thinking about this last couple of week. it's like TH-cam algorithm is in my brain.
The LOOKS, always starts with the looks and this is bang on. Even better than the Lilium.
Now , i comprehend the Dyson fan. You know the concept will be manufactured cause the idea is fully fonctionnal in my dreams & thoughts. Great video, perfect time for an intro Bravo ! Mahalo, Claude
Amazing video as always. Really loving this channel! Keep up the great work!

Once the right breakthrough is achieved and financial backing is secured can it materialize to something. Note that this can happen multiple times until said product is commercially viable. (VR comes to mind).

Inside the plane, with the motor in there, I'll bet it makes one hell of a scream, outside pretty quiet.
What's the noise from a Dyson room fan compared to one with blades ?
I love this. Please stop talking about flying cars. You dont want one. Go fly an airplane some, and understand, one cant pull over if there is a problem. So the reliability MUST be very high. Cars breakdown all the time. You never want an airplane to break down.

@@DartTyler Biggest red flag
Fully agree. If this "multiplies flow", then just route the output of one such "jet" back into itself, or through a chain of them, and voila - infinite energy. This might be just another of those beautifully-rendered graphics presentation.
@@markozagar The catch to that, in practice, is that flow multiplication relies on high pressure at the intake, and low pressure at the output. If you create a circular chain of these, then taking an arbitrary start/end point along the circle, the pressure will be LOWER at the intake of your "start" point than at the outlet, because the pressure will consistently drop across each propulsor in the loop. Kinda like the time zones need to reset at the International Date Line because they can't keep going backwards forever.
So the physics of the idea is sound, but putting them in a loop to create infinite energy is not.
@@markozagar The issue is that this kind of device is great for moving air around a room and for propelling a model aircraft, but the physics does not scale up very well. Doing something like this for propulsion of an aircraft that can carry a person would use way more power than a conventional propeller that's electrically driven. I just cannot see something like this being efficient enough to knock other modes of propulsion of their throne.

This all looks lovely in CGI but back in the real world these fall down when transitioning between flight modes.
It's still cool, if they are improving their design and working out the kinks
Even if in this case the kink is falling out of the sky
The model at least seems to be flight worthy. And there are already aircraft using the exact same transition method, albeit with classic jet or prop engines. It really only depends on being able to generate enough forward thrust to reach sufficient aerodynamic lift through airspeed before losing vertical lifting capabilities.
@@JescoLincke the transition is easy to do in CGI, or in a sentence, but it has to happen reliably in the real world. It is not a trivial problem.
@@kalliste23 I agree that it is all but trivial. But the principle has been proven to work in certain aircraft already in use (e.g. Osprey or other tilt-rotor-aircraft). That doesn't make development of this concept any easier, but it shows it could be done.
@@JescoLincke Osprey is a good example - go back and check out the history of the development of the Osprey and the mind boggling amount of money that involved.
So much like the dyson bladeless fan, it uses more blades than a traditional fan, cool
extremely informative video; thank you! New sub from me!
So, this is essentially powered by a pair of Dyson fans. Intriguing, but I don't see this "taking off".
hahaha
Ah but have you imagined a Dyson fan powered by a small turbine putting out 700hp? Does that help your thrust equations? lol
@@edfrawley4356 and how does that turbine produce that propulsion?
*Blades.*
@@davecrupel2817 so does the dyson "bladeless" fan. your point is moot.
So. Not bladeless. Not cheaper.
AOC Sez....nope. uses FUEL.
6:26: this video Gets a LOVE. I don't get the principle behind it, but VT without visible downward facing thrusy just blew my mind.
The canard and the front fans need to integrated into one design, I am sure the front fans could act as canards without the complication of being stowed.
No, the problem is, once they stop producing the thrust for VTOL, any sort of open ended tube like that (of almost any cross section and wall profile) will then produce a tremendous amount of drag. In fact it usually produces more drag as an open tube than it would, were the opening completely capped (a solid profile from the front).
@@daemn42 I'm wondering how they are powered. If by, say a PT6, then I hope they are cooled in the airstream prior to being stowed!
wasn't "dyson fan" just a less efficient fan, as it would hide it in the base and then spread and angle the air, which loses energy with every bump and turn
Exactly. An aesthetically pleasing novelty. Those steel bladed fans from the 50s were probably as efficient.
Quiter and provides a much smoother airflow, good for personal use if "money's no issue". Efficiency is said to be better for fan models, but that's probably because of the expensive materials and optimized design, that offsets the poor theoretical efficiency. Or just improper measuring.
Very nice aircraft. The Wright Brothers would be proud and amazed!! Good job ! I hope to see this become a reality.
It appears that the air multiplier effect also serves to reduce the effective "disc" loading.
Another youtube recommended :/ how do people believe these companies when their "test" model uses standard propellers and their aim is all about the propulsion system not the "pretty" shape of the body.
It may be logical to learn things like VTOL, flight dynamics, and other things independent from the propulsion. But not for much else, as these small planes behave very differently from real size ones.
Still, the concept is excrement prime, I wrote a long comment about that.
this one actually real) it will still be a failier but it can work
Because cgi can fool people into thinking it's real.
@@raykent3211 what?
Very well explained, with good visuals of how it works. Thank you for the information.
Wow! Now I know why Elon backed out of the VTOL jet. This thing is amazing! It would also be interesting to see how it performs on engine failure as the flight characteristics could be problematic with that....
There is no redundancy. And that is a weakness of this aircraft
There are parachutes for small planes that will lower the whole craft down. That's still dangerous, but I think safer than that thing's likely glider performance.
