Rocket Science: How the Raptor Rocket Engine Works and Full Flow Staged Combustion

What is full flow staged combustion?
How does it work?
And where did it come from?
These questions and more will be answered as we review rocket engine cycles and follow the historical development of more sophisticated and powerful rockets over the decades.
Finally coming to the debt that all modern rocket companies owe to the genius of those who have made it possible for massive reusable space launch systems like the New Glenn and SpaceX Starship to be developed.

WOW! Just WOW! Your lessons continue to amaze me! Well-researched information presented in a digestible format bordering on art! Keep up the great work, my friend!

Funny story, I work at the site in which RD-AMROSS is located in WPB. The entire “facility” was built to produce“one” functional asset and convert all RD-180 Blueprints to English. Right before they tore down the mock-up, we got to tour.
It is also the birthplace of the RL-10 and SSME ATD. They were doing some RL10C development work last week. You only hear the steam when it runs. Thanks for your awesome explanations for us jet guys 😊.

Great video, again. These are all very well done and super informative.
This site should have 1M subs

Your reverence for pioneers is palpable and contagious, thank you for being a fine node of revelation.

Thank you for speaking about cavitation because when I first learned about it it was very confusing on how tod walk with it, luckily I have a engineer friend who works on submerines and I found out there are 3 ways to deal with cavitation the size of your turbine, the presure of the fuel and the tempture of the fuel so when I looked at the ssme and saw the low pressure pump and guessed that's what it was for, I was able to figure out it's purpose and I'm happy your spreading that information. One more thing is could you speak about aucostic combustion instability in rocket engines as I have been having problems getting full exsplainations about it. It's eaeist to find how the fix it in plane engines then rocket engines and might be a good lesson on hoe sound effects engines as well the launch area around it which is relevant to space x right now. Also if you want to learn more about engines there is a great ressaerch article called a survey of automatic control methods for liquid propellent rocket engines on the hall archives website. They speak about controlling the rocket engine and touch on much more. Thanks for the good view

Another important Class for the Terran Academy Library, Admiral!

[lyleblack]

Excellent explanation, and an even better salute to dedicated visionaries, scientusts, researchers, and engineers.

[linyenchin]

Fine context for the flow of possibility. Reaching our potential in the hope to extend our realm of expertise as children of the stars.

[jt-dbtb]

Your content is amazing wasn't expecting this format for so e reason. Thank you!

[g.f.martianshipyards]

I really like the flyback-boosters of the Uragan concept. I wonder if the extra hardware weighs more than the propellant a vertical-landing booster would need to keep in reserve.

[scottdorfler]

Everytime I think I know it all I watch your channel and realize I don't. Another great video

[WayneBorean]

Excellent work. I’ve learned more about rocket engines from your videos than any books I’ve read. Your presentation style is superb.

Could you cover some of the private historical projects like the Roton? I think the ideas behind them are worthy of study.

[makespace]

Easy to follow, very well presented. Thanks!

[nearth]

Awesome job!
Thank you for yet again another fantastic presentation. Keep 'em coming, one day soon this channel is gonna explode with eager space cadets of a younger generation than I; a lot more likely now than when I was a kid to be stepping out on Mars for an enchanted evening under the stars. Yeah!

[sashagrinevich]

An incredible video. I am currently doing master's on space engineering and your visualisation of a fuel rich staged combustion cycle is exceptionally useful. Thank you for the material. Btw, Korolyov was also Ukrainian, born in Zhytomyr and studied in Kyiv Politechnic Institute ;)

[michaelplotkin]

Another great video. Thank you for the hard work.

[joseaurelio]

certo valiouse these contente.
well done

[Canxd]

Woah, I have never heard of the UR-700M before. 750t to LEO is just insane. Even more insane than Sea Dragon!

[toddmathews]

More please. Has some who's first memory is Apollo 11 I find these fascinating.

[rayoflight]

Thank you.
I like the incremental improvements you are making to your videos, which are getting better each time, both in the visuals and the descriptions.
I didn't know that NASA had already a body of research on a full-flow power pack (named BE4 ?), on which SpaceX could later impinge on.
How generous of NASA!
Once more, thank you for all your efforts in sharing knowledge about rockets...
