What it's like inside rocket engines! Viking 2 and Vulcain 1! 

Even Scott Manley told em 😂

When the Awesome Scott Manley knows more than a museum display! LOL

bruhh those guys better change is now.

Isn't it the propulsion system of Ariane 4 too btw? (not Ariane 1)

Wow 😂

Correcting Elon fixing museums

I mean the museum had it wrong for a very long time. If i remember correctly it was already wrong when Scott Manley did his video.

The guy from dude perfect was first for RU-vidrs if you count Jeff’s penis rocket

Maybe. Someone could always just throw cash at Bezos and get a commercial astronaut ride.

@@patreekotime4578 Can't compare the Bezos joyride with a trip around the moon!

Actually, of the people from Dude Perfect went to space in a New Shepard.

I think that one guy went to space on New Shepard. So Tim will the first (probably) in orbit and around the Moon. But then again almost anyone has a RU-vid channel these days so what qualifies for a RU-vidr? I would just say Tim will be the first Dodd in space :D edit: nvm, smeone else was faster

Safran took over later. The engines were designed in LRBA (Laboratoire de Recherches Ballistiques et Aerodynamiques) which later became SEP (Societe Europeenne de Propulsion). The chief designer of Viking was Karl-Heinz Bringer, but he was not the one who came up with the thrust chamber design -- this came from elsewhere.

@@cogoid good addition ! I didn't knew about that ! My knowledge start at about 2013 when it was named Snecma :)

@@RomainCavallini Oh. It actually goes back all the way to Peenemünde. After the war, the Germans who did not go to USA or USSR were starving to death, and they were offered food if they were willing to come to Vernon and work on Super-Vergeltungswaffe 2. Some decided to join, and there was a village of ex-Peenemünde engineers established in the forest on the other side of the river from Vernon. But there were no funding to actually make Super-V2, so they switched to the much smaller hyperholic Wasserfall rocket, and derived a small meteorological research rocket from it. They named it Veronica. But they could not make it to work reliably. The engine worked well most of the time, but sometimes unexpectedly exploded. Fortunately, another group which was working on antiaircraft missiles "PARCA", has developed in late 1940s a reliable hyperholic engine which did work reliably. In the end, they did not use it for the military missile (it switched to solid fuel), but it was adopted for Veronique AGI. This is where this design of the injector and of the whole thrust chamber came from. That was little by little scaled up without changing the principle to Vexin, Vesta, and Valois. Then Karl-Heinz Bringer, who was an expert in gas generators, suggested to bulid a turbopump-driven engine, the Viking. There were of course largely thousands of French engineers and many French companies working on these developments.The Germans only provided some guidance based on from their prior experience. There were also contributions from international partners. AFAIK, the turbopump was made by a company in Germany. And the fuel seems to have even come from the USSR, with which France always had a special relationship.

I think it is somewhat sad that there is so much French engineering brilliance trapped in the EU beauracracy - so many great things that could be invented by them!

@@bartwaggoner2000 Bureaucracy can be a drag, but cooperation between European countries is essential. The combustion chamber and the nozzle for this engine, though designed in France, are actually fabricated in Sweden. It's really good to combine the best know-how from every country.

bro started correcting museum sign lol just shows how knowledgeable he has gotten all these years

cant wait for the 5min video! /

@@Half_Finis oh there is a bit to talk about, just on the Ariane you have Viking, Vulcain, Vinci, Aestus and HM-7B, plus a bunch of various size solid motors, and those all use different fuels and cycles plus sometimes super unique design choices like on the Viking shown here... it's not as large a family as US engines and definitely nowhere close to the insanity of the soviet union but still can make for an interesting video :)

And they aren't really french engines anymore (at least for the Vulcain 1), because nowadays there is a lot of development from countries Germany and Italy too. The Vulcain 2's test site for example is in Germany and there's likely a lot of engineers from all over Europe working on it.

@@cromefire_ I was speaking specifically of this line of rather simple French engines with annular injectors. These are quite unique, and their basic design stayed the same for several decades. There are no mainstream engines from the USSR or USA that resemble these, even though in all three countries the development was conducted by teams of engineers of many nationalities.

Good luck buddy

Learn how to maintain every engine possible.

Check out Rocket Propulsion Elements by Sutton. Make sure you learn your calculus (including differential equations and multivariate calculus and vector calculus). Make sure you learn lots of linear algebra. Good luck!

Good luck from Australia mate, if you apply yourself you’ll get there!

thank you all so much :)

I was thinking the same thing.

Ya I was thinking how cool would it be to be the dude paid to cut up a whole rocket engine and what kind of blade did he use

Now they need someone who can light it so the curious attendee doesn't need to bring his flashlight app.

Cobalt is what high end drill bits and end mills are made of. Taking a hacksaw to this nozzle wouldn't even scratch it.

@@AcidGambit419 abrasive zipcut wheel. .045 ( aprox 1 mm ) thick or a jewelers saw blade . the abrasive blade cuts pretty much anything.

Seconding that. Would be really cool to see Tim tour around to different complexes and exhibits and do a fun little learn together video. I know the man is very very busy but it's just an idea. This video was awesome!

Watch my video on how to start a rocket engine! You’ll learn all about it!

That's why you see white vapour pouring out of a starship during a hop and ice coming off a F9 while it's coming back. The engine chill system.

yep, this not only protects the pumps from thermal shock but rather also the propelant from boiling due to the warm pumps, which avoids bubbles that can damage the pump to destruction.

I'm impressed they can chill down the turbo pumps -- without having leaks from the hydrogen side into the oxygen side (hydrolox). Or from the oxygen side into the RP-1 side (kerolox), or from the wherever to whereever (methalox).

@@EverydayAstronaut are you still in Holland?

Thank you! I enjoyed doing those, I feel like it added a lot!

Spacesuit still there, in cloth form .

This was a relatively uncommon design. The guy in charge of the development of this engine was a specialist in gas generators. He invented the three-component gas generators during his previous tenure at Peenemünde and naturally wanted to use them for everything. The cool thing is that you can adjust the temperature of the steam at will, and the gas will also not explode if you use it for pressurizing both the fuel and the oxidizer tanks. But for this to work well, the steam still had to be very hot, at a few hundred degrees Celsius, and this mandated making the tanks of the rocket from steel, which, unlike aluminum alloys, maintains strength even at elevated temperatures. SpaceX uses steel for Starship for a similar reason.
