SpaceX Insane Raptor engines power the Starship that Musk is taking to Mars. What makes them so good, and why are they called the King of rocket engines?
This is a sneak peek into the Insane Engineering of SpaceX's Raptor Engine!
The Starship is nothing without its Raptor engines. They produce the thrust to help the Starship escape the earth's gravitational pull and propel it on its interplanetary journeys.
The thrust they produce has to be enormous, as the Starship is meant to lift heavy payloads of up to 100 tons. This is important if Musk's dream of planting people on Mars is to materialize. All the stuff necessary for life will be transported to the planet by the Starship.
SpaceX is not short of powerful rockets. Part of its roster of spacecraft is the Falcon 9, which is partially reusable. It is capable of blasting payloads up to 22,800 kg to low earth orbit. Falcon 9 is powered by the Merlin engine, developed in-house by SpaceX. It uses oxygen and rocket-grade kerosene as the propellant and can produce 854 kilonewton of thrust at sea level and 981 kilonewton in a vacuum.
However, the Starship needed something more powerful, and SpaceX decided to build a new engine, naming it the Raptor. With the design, SpaceX is introducing lots of insane concepts that few rocket companies have tried.
The result is a beast masquerading as a rocket engine. Each Raptor engine weighs about 1.5 tonnes and will supply 11 million horsepower to the Starship, the equivalent of four Hoover Dams!
By comparison, the Bugatti Veyron, one of the most powerful sports cars ever made, has an engine that weighs one-third but cannot produce more than 1,200 horsepower.
The exhaust of the Raptor engine is expelled at over ten times the speed of sound. If that is not crazy enough for you, the fuel in the chamber burns at temperatures high enough to melt the chamber's walls!
If you wonder why the wall does not melt, that's because of the clever way the flame is kept away from the walls by manipulating the flow of the gas. Super cold fuel is also pumped through the walls as additional security.
Design
The Raptor engine works like most rockets do, expelling gases fast enough to push the spacecraft forward. However, a lot of clever engineering makes the Raptor a mighty rocket.
The engines depart in their design from standard fare for rockets,, as SpaceX opted for a full-flow staged combustion cycle. Inside, engine ignition is handled by dual-redundant spark-plug-lit torch igniters, which means there is no need for a dedicated, consumable igniter fluid, as found in the Merlin.
The Raptor combines methane and oxygen that is deeply cooled for propellant, near their freezing point: this way, the tank stores.
At such low temperatures, the propellant is denser, which increases the overall performance of the engine.
Methane is better fuel because of its higher performance and lower cost than kerosene or hydrogen-based propellants.
Methane is far easier to store than hydrogen as it requires less effort to keep it cool at cryogenic levels. It also weighs less than hydrogen, meaning more methane can be stored in the same tank.
Methane is better than kerosene as the latter forms residue during burning, known as coking, limiting the rocket's reusability.
The higher efficiency means with almost the same size as the Merlin engine, the Raptor engine produces far higher pressure and thrust.
There is simply no other rocket engine in existence capable of producing as much energy using liquid methane and oxygen as propellant.
The development of the Raptor engine is incredibly impressive. Especially when you consider that the CEO Elon Musk didn't study anything rocket science in school but taught himself everything by listening to experts.To keep improving on my videos, I took a class on Skillshare.

Kommentaarid

  • Elon musk and his space X is spinning the earth fast

  • When we are living on Mars can we then rename it to Tattooin

  • RD-180 chamber pressure is closer to 267 bar, not 31 bar. 330 bar is correct for the Raptor test.

  • Goodddddd

  • You mean for a suicide mission to Mars. All under the disguise for a so called Global Warming (or what ever it is this week). Elon Musk is an idiot.

  • SPACE-X AND NASA FOR THE WINS!!!!! LETS GOOOO!!!! 🏁🏁🏁🏁🏁🏁🏁🏁🏁🏁🏁🏁🏁

  • okay hear me out.... MIATA!

  • That engine needs the entire ship, only it, for fuel ... and that to get to the moon? Did I hear Mars ?? I mean ... go out in the neighboring room ... nothing more ... these have no futures ... the closest star is 4 light years away ... about 37,842,921,890,323 km ... I mean with 300,000km per second, it takes 4 years to get there ... and with those rockets it was achieved with difficulty about 40km / second ... I mean ... a few schisms to satisfy dreams .... where are the engines ... photonic, or nuclear What did they talk about with enthusiasm as a child? .... well nothing ... go to ... mars ... ok a cold desert and nothing else ... 🤣🤣🤣😂

  • This video is riddled with errors!

  • how to fuck you compare a car engine to a rocket engine?

  • I can see how the military could use these rockets to quickly deliver supplies and weapon anywhere in the world in a matter of just a few hours to the nearby battle fields. This would make conventional strategic airlift less important.

  • You know the moment we have the perfect anything it becomes obsolete to a totally new technology! History tells no lies, only humans do and anti-gravity is that technology! Can you guess who else knows this?

  • That wasn't a Veyron.

  • OMG….I call BS on all of this.

  • Guess we're not allowed to discuss the huge amount of pollution that manufacturing these things creates. As this planet people overheats and we get choked into extinction. But that's ok. Let's all worship his dream.

  • must we call everything insane?

  • we should probably worry about the abundant problems on earth.

  • HEY, col thing is the gimbeling but no one ever explains how that is done. come on guys.

  • Oh ya.. Hear comes the army.. we will just steal this.. Thank you very much.

  • Yeah? So those engines will be powered by batteries? A green and clean energy so the climate is saved? Incredible how they shoot themselves into own legs by car engines but keep going with this space crap...

  • like omg, literally SO insane !!! omg

  • I love SpaceX and what they're doing, but this level of fangirling is just embarrassing. 6:03 "[The Raptor] crushes other in efficiency and safety." This claim isn't even true. The Raptor has had several failures in testing, a couple of the other rockets on that list have had none; and the Raptor has zero safety record in production. As for efficiency, the chart you show in the background shows that the RS-25 is more efficient.

  • Overhyped.... pff, YT is full of overhyped channels now.

  • 1:59 that diagram is of a merlin engine (open cycle) and not of a full flow staged combustion cycle raptor

  • Are chilam

  • Methane is not abundant on Mars, and it is obviously heavier than Hydrogen.

  • Wernher von Braun seal of approval.

  • This video is utter garbage.

  • Good old South African, Elon Musk :) The power of Africa!

  • 2050? I wish he sees him dream bear fruit 🍉

  • It looks like this Musk is a genius...🥇

  • I'd say buying expensive experts rather than listening to experts

  • The is no evidence of methane on Mars (except traces) but CH4 can be produced on Mars from the 95% CO2 of its atmosphere and water that we must harvest also for survival, and oxygen to breathe. Nothing is easy with Mars; we are much closer from the space vehicle to go there than from making a viable long term habitat on its surface.

  • 7:50 - That's really dumb (the sea level variants are supposed to be for landing on Earth and on Mars). The atmosphere on the surface of Mars is equivalent to 100,000ft on Earth so it would be a lot more logical to use the "in-vacuum engine" for landing on the surface of Mars.

  • Bruh 2000hp Car Lotus Evija or Evira I forgot.

  • mars is a light reflection. can't be landed on. you are continually being punked by all these phonies.

  • 8:20 It’s either “on the table” or “in the cards” It’s not rocket surgery

  • I think that you don't need 1000 boosters if you want a fleet of 1000 Starships to Mars. The booster can be reused quickly and launch a few Starships a day. In that case you moslty use 6 engines on each Starship. So I think 800-1000 engines per year would work out.

  • Hello 👑

  • can we stop talking bout musk as a saint? Thank you, The people of the world.

  • Million dolar to make one engine 😞😞😞😞 i can't not eben afford to buy a Lamborghini that is cheaper 😌

  • Its cool but it uses to much fuel. They need to research and development new smaller more powerful power supply's. Nuclear at least. You cant space travel with gas tanks.

  • Buggati Chiron not Veyron. And the schema was not full flow. Come on, take your homework

  • Why call everything "raptor"?!?!? Next thing a vaccine called raptor, a phone called raptor, a new type of resin called raptor, etc., 🙄

  • 1:20 in an I can't stand it. Insane, insane, insane nope I am done.

  • Oh cool. I made a sandwich the other day. But this seems ok too.

  • so, this channel is one of those channel created to glorified Elon Mask false marketing and claims? what a sad existences...

  • Trips to the moons of Jupiter, not jupiter itself.

  • Turn the F1 into a methane burner. Better yet use the Aerospike!

  • Musk is going to way pass Bezos as richest person on Earth soon.

  • Maybe you can credit the insane engineering of the Raptor Engines to, you know, the actual engineers who led its development? I.e. Tom Mueller and Jeff Thornburg.

  • the new question is, how much liquid oxygen do we have xD

  • No doubt about it. SpaceX is putting all other aerospace companies to shame. The amount of progress spaceX has accomplished is nothing short of mesmurising. I am so lucky to be alive at such a time as this.

  • Man, this thing is a work of art. And it’s components can be 3D printed? He just might reach his goal of 1,000 rockets if that’s the case.

  • Ill tell ya'll what IS INSANE! IT'S INSANE THAT WHEN WE LANDED AND DROVE AROUND ON THE SURFACE OF THE MOON COLORED TELEVISION HADN'T BEEN FULLY INVENTED. THE BIGGEST & MOST ADVANCED COMPUTER WAS THE EQUIVALENT OF AN VERY AVERAGE POCKET CALCULATOR. THAT THE ROCKET TECH TODAY IS LESS THAN WHAT IT WAS 50 YEARS AGO BECAUSE ALL OF THAT TECH WAS DESTROYED AND THE INVENTOR'S ARE LONG DEAD. THERE ARE NO SCHEMATICS OR ANYTHING. THAT IF A HUMAN LIVES IN SPACE FOR 100 MONTHS ALL OF HIS BONES WOULD HAVE BEEN PISSED OUT IN URINE AS CALCIUM. AND #1 INSANE THING IS THAT THERE ARE RELATIVELY A HANDFUL OF HUMAN BEINGS IN CONTROL OF OVER 100,000 NUCLEAR WARHEADS ON PLANET EARTH AND EVERYONE THINKS CLIMATE CHANGE IS OUR BIGGEST PROBLEM.!!!

  • 1:20 this scenario is so gorgeous.

  • If SpaceX cant land the starship And take off then a trip to the moon or Mars will be one way.. Unless it never lands.

  • Just stopped by to say your thumbnails are total clickbait rubbish.

  • 1:27 rlly... that's not a Veyron...

  • 100% this channel will get more than a million subscribers

  • Dweebbois use "Insane" without knowing what it means. And as a result sound like they're 13 year old dweebs. Hopefully they'll grow out of it.

  • Co2 is abundant on mars, not methane...

  • Pentagon : we will need to talk to all your engineer and have a look at your engine design. PS : believe me, this is not secret, if you learn history, every and i mean every technological leap will be coming from the military not vice versa.

  • No outsourcing. Will Musk be the next person to be taken out by the jealous globalists?

  • Hey, apparently I wasn’t in the first 1000 subscribers so I didn’t get my free Month of Skillshare…. Any Plans on making this cooperation again?

  • Correction RD-701 Until 2020, the engine held the record for the highest pressure successfully recorded in a combustion chamber with a pressure of 30 MPa (300 bar; 4,400 psi). This record is August 2020 was surpassed with 330 bar achieved in the SpaceX Raptor engine, also experimental as in 2021. en.wikipedia.org/wiki/RD-701

  • Илон Маск как Дарт Вейдер будет захватывать страны.

  • Superb

  • No, methane is neither lighter nor perform better than hydrogen. It has the lowest efficiency of all rocket fuels today.

    • Methalox is way more efficient than both Kerolox and the hypergolics used in other rockets today, just hydrogen fueled rockets are even more efficient.

  • That was a bugatti chiron btw not a veyron lol

  • Why is your channel so bad

  • how about co2 reduction...

  • Elon hired people to make the rocket IDIOT HAHHAHAHAHAHA

  • Who is ready to travel to Mars?

  • 1:26 that's the chiron!

  • Eventually we will be travelling to planets and moons where there is lakes of methane.

  • Too basic.

  • SpaceX's part time job is to make Rockets. Their main job is to give goosebumps Everytime you hear the name!

  • too much non engineering info, and low on actual technical/engineering side. Hype riding

  • I felt i watched an intro instead of an video about the raptor engine. The same forced voice the whole video long. Not for me

  • Afaik you cannot attribute a rocket engine with hp power. You can only measure a thrust. This Bugatti comparison is totally dull

  • When I hear someone mentioning horse power when talking about rocket engines, I sure know that either he or his audience has no clue about the subject.. Furthermore.. - Methane isn't lighter as hydrogen - Methane cannot be found on Mars (in significant amounts) - FFSC cycle means that alle the propellant goes through the preburner, the gaseous injection in the main chamber is a nice side effect - the raptor does not beat the efficiency of any hydrogen engine -.. You're mixing up so much stuff in you're hurry to fit that in a 9 min video.

    • -Burning Methane produces less thrust but better ISP ...

  • Thanks for sticking to the metric system

  • Pity about the bullshit advertising in the middle of the video. Made me turn off

  • Does the Raptor have a plaid version?

  • 6:16 Cybertruck!

  • If the Starship should visit Titan someday they are going to have a refueling depot with all the methane that moon has.

  • This is stunningly amazing. This is the Saturn V and N1 of our time. Will be a spectacular sight.

  • Another Elon Musk fanboy channel.

  • _Please add English subtitles..._

  • Because methane is lighter it you can store more?? That's not right

  • tell it to nasa!!

  • hahahaha the indian & china already ahead

  • Some people just don't deserve your love and devotion, because they are greedy and dirty.

  • Great teaching video, and fun...! I thought the plug for SkillShare was handled well....also!

  • Raptors, benefit from 3D printed parts. Strong as stainless? Titanium? Inconnell? What materials are available to be printed? Some heat characteristics as these? Strength at temp? Tolerance sub thousand's of an inch? ½? ¼? ⅒? Ever hear of peening the surface. Lessens crack growth.
