- เผยแพร่เมื่อ 26 ก.ย. 2024
- Last night Elon Musk posted a pair of low resolution images showing the new Raptor engine getting ready for testing at the Mcgregor, Texas facility. Raptor is a next generation design using full flow staged combustion cycle, a design which has never been successfully flown, but offers superior performance and reusability.
7:14 scott says 300 bar might not be possible.... over a year later and they just hit 330 bar
He did say so soon, and maybe later. This is later
@@nicosmind3 lpplppppo
Bloody beat me to saying this have a like
Elon said that they only achieved 298 bar. But Raptor 2 is near, so...
@@antonpershin998 he said on twitter aug 17, 2020 that they reached 330 bar. not the operating chamber pressure for rap 1 but they’ve reached it.
Scott, you don't get enough credit for having just the right length of a musical intro.
I was just thinking I'd like to have a 10 minutes loop of it...
Yes short and sweet but gets the point across
Nah, too long. GTTFP.
Best bit
*I BROKE THE 420 LIKES* 😈😈😈💩
Nobody gets me more hyped about rocket engines than Saint Scott.
Jesus Christ its Jesus Christ!
I believe in the Raptor, and I believe in you Jesus Christ LOL!👍
It's a work of art 😭 - Tell you what Scott.... *these are pretty good times to be a fan of space exploration!*
> It's a work of art
It will be - if its expected parameters are confirmed.
@@vladimirdyuzhev Fair!
Id rather live in a colonized solar system!
Scott, you got any dope on the JWST ?
scott is old. he might not make it seeing the first human on mars.
A year and a half later, the Raptor achieves 330 bar of combustion chamber pressure.
Fours years later starship has launched with over 33 engines

Put that on a t shirt and I’ll buy it
Me too
Yes
9:22 when she sends you pics
HAHAHAHAHA its perfect to take out of context
this is better.
Boy these pictures look amazing! I wish i could just get in and look at these and examine the plumbing XD
When Elon sends pics
Examine the plumbing....
Rocket Scientist or not, I actually understood the different designs of engine and that is a triumph of explanation! Thanks as always for great videos.
"To explain that, I'm going to have to give you all a little bit of a lesson in rocket science."
This channel has always been something special.
watching this after they landed SN15 in May 2021 and they achieved 300 bar : ) and not only that
Love to see you see you interview Elon in the near future Scott.
Only if he pretends to smoke a joint again.
@@Nilguiri - If they both shared a bong it would go viral
@@FandersonUfo
It's more difficult for Elon to fake smoking a bong than a joint. He might actually have to inhale this time!
Scott is too smart for Elon
FandersonUfo I would love to buy Elon a beer and chat with him about sci fi, his vision of the future, his thoughts on the future of space, his favorite sci films ect. Be really cool just to chat in a beer garden and engage with him.
What a beautiful and powerful engine!
@David Parry you act as if you could build it.
Is the Raptor engine going to be used on the hyperloop in the Boring tunnel?
And about a third the power of a F-1. So, fifteen engines, instead of five?
@David Parry yes, yes it is.
big deal germans had this in the early 20’s ,
Elon Musk walks into a bar, and enjoys his drinks so much he decides to buy it! It turns out, he's really good at managing bars, and his new company, Raptor, is growing fast. Years later, he decides to build another bar near his favorite launch site.
Scott, hearing this, calls him as quickly as possible. and says, "You can't do that, Elon!"
"Why not?" he asks.
"Three hundred bars?" Scott replies, "It just isn't possible."
LOl so dumb... but funny! :D
Not possible you say? Challenge accepted!
"It's necessary " cit
Wonderful. Except Scott is from Scotland, where 300 bars are possible anywhere. OK, we have to do a unit conversion. 300 pubs.
You're ready for fatherhood.
It's so great to come back and watch this video again (December 2020). Then it was conversation about Hopper's nose cone, now it's all about SN8's flight. Then it was questioning whether Raptor could hit chamber pressures and thrust levels they previously claimed, now those are in the rearview and we're wondering just how much better the Raptor could even still get in the future. Imagine what it will be like watching this video in another year! It's just incredible what SpaceX is achieving.
The speed of which spacex is innovating is crazy.
7:24 I think they reached 330 bar 🤔
300 bar. Possible.
So damn good to see the US building awesome rocket engines again!
It truly is! But I'd like to remark that the guy behind all this was born in Republic of South Africa and studied in Canada. :D

Just wanted to say how much I love your videos! No "like!" "subscribe!" "buy my merch!" "visit my sponsor!" nonsense. Just enthusiastic , honest info on topics that you are truly fascinated by. This is what TH-cam is all about!
At 7:15 he says 300 bar isn't possible- fast forward 1.5 years and we have 330 bar!🤣
" HELLOO,SCOTT MANLEY HERE "..lol gotta love this dude's voice. His tone he uses to introduce himself NEVER EVER changes..GREAT JOB scott, NASA NEEDS TO SEND THIS GUY TO SPACE!
"im not really a rocket scientist, I'm just a nerd who loves rockets." Every KSP player ever.
This is 2020 and Raptor has achieved 330 bar
Hey Scott, you need to make a ringtone for us of you saying "heulllloo its scott manley". We would love it😂
you can do it yourself.
It’s incredible the difference 2 years can make
6:42 my god those are some beautiful flames...
Scott, I'm from two years in the future. You won't believe what they will doing with the Raptor engines down in Texas!!
Full flow staged combustion sometimes happens when I eat jalapenos
It's known that jalapenos and air enter the organism separately, then they mix inside the digestive system and exit out of one's rear end explosively.
Nature came up with the design a long time ago
The fuel rich precombustion in my stomach sometimes rumbled, non- linear laminar flow problem. Ablative coating to my rocket knozzle might help with the extreme heat problem .
And it burns, burns, burns, that ring of fire ... :)
How are you cooling the nozzle? I copped a catastrophic meltdown doing same thing lol
Watching this video after the successful flight of SN8. You're one of the biggest or maybe THE biggest asset of the space fan community. Love your videos.
I read "The next Scott Manley video is going to be great" on Reddit and here I am verifying that.
Wish I would rewatch this in 100 years
Scott "1 million subscribers" Manley as he will soon be known.
1 million Manley?
Scott Millionley
Honestly don't get why he doesn't have 1M already.
The only person who comes close to Scott when it comes to explaining rockets \ space is Dustin from Smarter Every Day. It would be interesting to have the two talk about rockets.
31k more
Scott said: "That amount of bar is not possible."
SpaceX: "Hold my beer."
Could go higher with a denser fuel, but kerosene is too dirty for a closed cycle fuel rich turbopump so a full flow engine would be impossible.
Beautiful flame on that
How far they've come.
Who is here after the 150 m hop? :D
Yup! The progress in a year and a half, with loads of setbacks in between... Frickin'-A.
I'm here after the 12.5km
im here after sn10 landing. 😎
Awesome video, particularly for someone who's on a propulsion learning binge. And that outro music is epic.
First we had Merlin, now we have Raptor. First a wizard, then a lizard. What will be next? A blizzard? A dizard? A gizzard?
Awesome. And a very pretty picture.
Marc Zucc
Lol..they are both birds not lizzard or wizzard. Raptor being something like a group of birds.
The plumbing on that Raptor has got to be a thing of beauty. Figuring out how to route all of it as compactly as possible and all the wiring and computers etc... just fascinating. I can't wait to see footage of this beast firing. The mini test article was impressive.
Thumbs up for Scott Manley to be onsite for the Raptor Engine test firing!!!!
just not... in front of it. :-S
My twisted sense of humor took this comment as sinister towards Scott Manley, even though I know you didn't mean it that way. 😁
Love Scott when he drops in on the Lab Padre webcasts during tests.
Great explanation of a complicated subject.
Scott......Why doesn't Elon fund a game parallel to his spacex rocket design program. Would be awesome to "test" his designs in a simulated solar system. I wouldnt mind helping his rocket program by giving him money.......as long as its a good game that tries to simulate real world mechanics.
Roy Bitmead
Based on the Kerbal Space Program, you can add some kerbolized SpaceX mods and Real Solar System. That will work.
In the interstellar extension mod, you can find the Merlin 1D by “Elon Kerman’s space exploration co.”
The Rocket Science Lesson was AMAZING!! DO A SERIES!!!
Last time I was this early Falcon 1 had failed again
John Whalley Is Dedicated AF
Dear Scott. If it were not for you I would never know about full flow staged combustion rocket motor. You are the rocket scientist teacher. Great video. Thanks.
Dr Mark
382 vacuum ISP !!! I need that in my ksp xD
Keep in mind it's methalox, so some of the gains are offset by lower density compared to RP-1 and thus greater tank weight.
its impressive. but ssme has vacuum isp of 452
@@145baggy Of course SSME is higher, it's burning H, not CH4.
@@145baggy The high isp of hydrolox engines is offset by the significantly heavier dry mass of the rocket (much larger tanks and insulation required). There are many other factors at play that result in the two propellant mixtures being fairly close in terms of mass to orbit vs mass of propellant efficiency.
Thomas Kwa kerolox should have about the same tank mass because it needs helium pressurization system whilst methalox (and hydrolox) can easily use autogenous pressurization.
We,as Truax Engineering, successfully conducted FFSC hot tests for in the San Francisco bay back in the 1980's but funding was cut when we were getting too close to full scale testing. Problem with depending on someone elses money unlike Mush had to. FFSC is the way to go to minimize combustion instability issues when scaling up like the F-1 encountered.
Want to see BE-4 & Raptor side by side on test stand and have rocket engine drag race.
Scott! For a nerd you are quite good and precise. I studied aerospace engineering with specialisation in rocket propulsion systems and have been working for some years in aerospace industry. Take it as a huge compliment from my side.
Correction after 2:55 "preburner" it's not, it's the turbopump GG exhaust which is dumped and gets a little extra thrust too. The Titan rocket brilliantly used it's GG exhaust for roll control for the single engine 2nd stage vs vernier engines that were used on the original Atlas rockets,pre-RD-180. Love your videos,Thank you, Ken
You should play some KSP! They have deltaV now.
'I'm a nerd that loves rockets' Me too Scott.
I don't know much about rockets, but this does help unravel the mystery to them for me. Thank you.
yeah... but actually 330 BAR. Baby😌
the controlled power of rocket engines is awe-inspiring
Excited to see the Boring Company build a tunnel for a SpaceX mass accelerator rail gun. Imagine a massive half mile long rail gun launching a payload into the sky where it then fires its engines and claws into space.
Never happen.. :)
As absolutely awesome that would be, it is 100% not worth it. Lol, it would require sooooo much engineering, tons and tons of energy, tons of preparation, and it won’t do much towards launching the the rocket. Plus having a static fire right before launch is helpful, something you can’t do in a rail gun type thing! But I am not gonna lie, it would be cool!
Great video Scott, thanks!
Yep the BE-4 is proving “easier to develop” 😟
Hello 4 year ago Scott Manley, youtube made me think this was a new video 🤣🤣
Yeah, the engine looks cool, but can the exhaust flame roast marshmallows?
Try 1 at the preburner exhaust and boom it’s coal
He looks so excited about the Raptor engine!
Rocket Science Rocks! Go Space X
This is the first time I've seen this video. I found it by searching for Raptor engine animations. I wanted to forward it to my brother to explain these engines. You are talking about 200 bar chamber pressures. Well they have already surpassed 300 bar and are looking to pinch a lot more out of it. I guess things move pretty fast in the SpaceX world.
Everyday Astronaut does a very long video explaining different engine types, from simple to this, just so people can understand what Space X have done
Big thumbs up for the great explanation of "rocket science"
In theory, these engines are so simple it makes me think that "rocket science" is not as complicated as people think. It makes the modern internal combustion engine in cars look much more complicated and impressive since they are building millions of car engines and they sell in cars for a relatively affordable price.
In other words "Rocket Scientist" have it easy.
I cant wait for the T-Rex Engine reveal! ;D
Any engine worthy of the T-rex name... would be terrifyingly big
The t-Rex engine will be the first interstellar engine
@@UNSCPILOT Yeah lets just hope that it wont go extinct thru a metor again! :D
The engines are named after birds of prey, not dinos.
Phillip Salisbury pretty sure you missed the humor there. Though one could say that birds are descended from feathered dinos so...But all the same, SpaceX isn’t even sticking to the same naming convention. Merlins are raptors. Raptor being a nebulous term used to describe birds-of-prey ie falcons, hawks, eagles, etc. If they wanted to "name them after birds-of-prey" then their engines would be called Merlin, Stellar, Harpy, Aryes, etc - all of which are Raptors!
Here after test flight. How humble our beginnings.
I don't know... you may not be a _professional_ rocket scientist, but you do study and teach the TH-cam world about the science of rockets... that has to count for something.
Yeah. I think he would understand the math if he sat down with rocket scientists. Would have to build a rocket to quality as one though.
Thanks for sharing the blueprint, I'm gonna build one in my garden this sunday
Hey Scott I think you meant to say "SpaceX Reveals Its Full Size Next Gen Raptor Rocket Engine" not "SpaceX Reveals It's Full Size Next Gen Raptor Rocket Engine". There's no need for an apostrophe on its!
Michael Hermenault Eats Shoots and Leaves!
Don't be 'silly, everyone know's that apo'strophe's are there to warn reader's of upcoming 'Se's.
@@Maeyanie I nearly dropped dead from fright 'since 'SpaceX didn't have one in front of it!
It’s been so long since a ‘Going Nuclear’ update that I forgot that series existed.
Best rocket science news analysis channel on TH-cam.
Tom Mueller has been working on this for over half a decade.
Elon said the Spacehopper raptors were a "mix of development and production" engine parts. I'm guessing this means that they hung a new-Raptor nozzle extension over the top of an old-Raptor engine, because Elon was super keen on having pictures.
Oh yeah i was waiting for that!
That engine looks amazing.
Appreciate the explainations, however, the graphics fip by too fast. Leaving them longer would help. Commentors: plz -thumbs up or down this msg so we all see what is prefered.
I agree with you, I rushed this because I needed to get to sleep.
I simply pause the playback for leisurely study. Saves bandwidth and Scott's time trying to decide how long to leave the graphic up. One can also then use print-screen to capture freeze frames for printout or other uses.
That is what the pause button is for. Also there is a slow motion function.
Scott has a separate video where he goes in depth about the different combustion cycles. Lookup the video about rocket plumbing.
Michael Amick downvotes have no function on TH-cam
Brilliant ! Both Tom Mueller and Scott’s reporting.
*Its
Monty Python's Flying Circus.
Excellent video. Thank you.
*Where did your launch escape system go?*
I wish I knew!
It escaped. Can't blame it, just doing its job.
Really excited to see full flown staged combustion cycle engine finally getting to space!
Fly safe everyone
I rewatched your video on rocket plumbing the other day and this video felt like a "do I really remember anything" test. I am happy to say I did.
What's so special about 300 bar?
The higher pressure, like in ICE's, allows for better atomization and higher chamber pressures. I might be wrong but thats what I get out of it.
300 Bar is a ludicrously high pressure for the relatively thin walls of a combustion chamber.
For example, a high performance engine for a race car that is likely to be rebuilt every race runs at around 100-120Bar.
The incredible temperature that a rocket chamber operates at limits the materials that are suitable. High temperatures not only reduce the strength of the material, but also produce issues with oxidization and corrosion, especially in an environment with oxidizer present.
It WOULD be easy to design an engine to withstand these temperatures and pressures, but, without some extremely clever ideas and cutting edge materials you end up with a ludicrously overweight engine.
So achieving 300 Bar in a reusable engine with a good thrust to weight ratio is still a cutting edge engineering problem.
And as for why 300 Bar and not another high number?
Because
THIS
IS
SPARTA!!!
Nothing really. It’s a number Elon threw out some time ago that raised eyebrows because the record is 262 bar. He responded to a tweet from Everyday Astronaut indicating that 262 was really hard and they are not there yet. So 300 bar has kinda become a holy grail kinda thing. But it’s really about Newton’s law , the higher the chamber pressure the higher the equal and opposite reaction. High chamber pressures are desirable but I think they are chasing the sweet spot between thrust, efficiency, cooling, materials, thrust to weight ratio, cost and reusability.
In case you are asking because standard hydraulics (or common rail diesels) having more than double the pressure:
In contrast to hydraulics you have
- huge flow rates (2 t/s in case of the Satur F1 engine)
- a rather big chamber diameter
- an open chamber
This might explain, why it is difficult to achieve very high pressures.
If you were asking WHY the want to achive this: Higher pressure means faster exhaust gases means higher ISP. Additionaly, the mixing of the components might be better, leading to a more complete burning, also improving ISP.
At least this is, what I think to know about it (regarding the 'why' part)
@@LoneStarr1979 thx
Original outro music! Yes!
If only people weren't so scared of nuclear engines. So much simpler, much more powerful and efficient. Still, the Raptor will undoubtedly be a classic.
I expect we won't be using nuclear engines until we can build them off planet. *sigh*
Not enough thrust for launching. But they would definitely help to get to Mars.
For starship, nuclear engines wouldn't make sense since they don't have enough thrust to land.
@@EwanKlinkhamerX3Emerald But you can make a nuclear-powered space-only interorbital tug to tow Starships between planets. Saves the fuel and allows for higher interplanetary payloads.
wait for interstellar Musk , maybe next generation
Yeah, some HD shots would be awesome.
Where is the Apollo CSM of you Saturn V?
Indeed no CM/escape tower. Having once had a Saturn V model of similar size, I noticed that, too...
Good job👍thanks 4 the update
Rocket Science?
That's simple, it is the *engineering* that you are talking about, come on!
Common sense.
Really?
It's true, I like to say that rocket science is quite easy. The hard part is rocket engineering where much of the effort is expended pushing the design as close to the limits as possible.
its true,even an idiot like me understands that rocket science is "simple in theory" but tremendusly complicated when you want to balance pressures/temps/weight/cost AND make as less possible points of faillure and million other things i cant think of.
You're not a rocket scientist, but just a nerd? Man, I need to step up my game. Thanks for helping me do so!
So now we have Raptor engines, but what about SpaceX's plans for the new TreX engine?
Really stealing my joke! Just remeber a Don never forgets!
"I'm just a nerd that loves rockets"
I can relate, I've always loved rockets since I was a kid in the Sputnik days.
I used to live in mcgregor tx. The engine tests would make every window on the house shake
Love all of what u do mate continue it s soo interesting ❤️❤️❤️
What's not to like about this video? Some people are just sad. Keep it up Scott.
I think that the SHS may go through a development similar to Falcon Nine, that it gets higher and more capable over time as Raptor evolves.
Thx for the for the videos about Space Exploration ! Always enjoy and (almost) everytime understand your explanations ! Keep it up !
You may not be a rocket scientist, but you are one to us! 😊. Love the technical content, as usual great stuff!
Yup! waiting for an interview with SpaceX! Kudos for the Videos!
the bad thing about watching this in relative real time is that you cant skipp ahead and find the test video but i cant stop watching these interesting videos.
