Hey ! French dude here, little fun fact, have e you noticed how all the engines have names like Vulcain, Viking, Veronique, etc ? They all start in V because they are designed in Vernon ! It's a small town near Paris that host "Safran Spacecraft Propulsion " the company that designed all these engines :) And to continue on the V thing, Ariane 6 second stage engine will be named Vinci !
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.
@@TheElipsus 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.
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 TH-cam channel these days so what qualifies for a TH-camr? I would just say Tim will be the first Dodd in space :D edit: nvm, smeone else was faster
Hey Tim! currently 14 and an aspiring aerospace engineer. ive learned almost everything i know from your videos and your videos were what inspired me to pursue this path. thank you for everything youve done and made tim. good luck on dearmoon! ❤❤
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!
This is awesome, like watching a BigClive exploration only with a rocket. Listening to the first principles reasoning about what different parts contribute to the whole is such a treat. The AR style pointers that stick to the object as the video moves are phenominal.
French engines are quite unique, and there is a rather long story of how they came to be this way. It all started in late 1940s with a conventional flat shower-head injector. It sort of worked, but half of the rockets exploded due to high frequency combustion instability. Then, in 1958 this annular injector was invented as a substitute. It proved to be much more stable. The 1958 Veronique AGI engine was then scaled up several times for successive generations of larger rockets. Finally, turbopumps were added, and this engine which we saw here became reality.
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.
Very impressive Tim. You know you've made it when you can confidently tell a museum that they're wrong, without even reading about the object that they're exhibiting.
I just watch a Docu last night on TH-cam from Free Docu about the Ariane and i said the same thing Tim. It was so cool to see a real in depth Docu on these systems cause we have never seen a real behind the scenes about ESA and Ariane
This is really cool. I feel like there has always been a disconnect between the simplified diagrams and the actual hardware in these engines, this goes some distance in helping bridge that gap, and understanding how rocket engines work in a lot more physical terms. Thanks for your content Tim!
Tim Dodd, You are the MAN!!!! You have definitely grown from when you started to now that you can walk up to a rocket engine you know nothing about and figure most of it out on your own!!! Even able to tell that the museum's display placard is wrong!!! Hat off to you for being so knowledgeable and self-taught!!!
Wow, great video Tim, loved the tour you gave and the (funny) annotations. That was a cool format. Wish I would have know you were there, just 40km from my home. I would gladly have stopped by to say hello. Impressive you can name so many parts from engines you haven't seen before. Very cool!
"Looking Inside Rocket Engines I don't Know Anything About!" ... the modern version of "staring into the fire" 😉 You did a great job explaining those engines without engine-specific detailed knowledge! Someone give Tim an honorary rocket engine engineer title. 👍
Good to see you in the Netherlands Tim! It's indeed a fun museum, and the ESA Open Day is always popular and crowded, have been there once! Have fun if you still here, or come back anytime!
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!
Tim, enjoyed the on-the-fly problem solving. I am sure a fair portion of your viewership do the same thing when we visit museums, myself included. The first time I saw a J2 engine in Durham NC, I spent 30 mins continuously circling and chasing fuel and oxidizer flows. ❤ regeneratively cooled engines.
Tim your content rocks. As always, after just a couple of minutes it's clear you know your stuff and know how to communicate. Keep them coming like this. Can't wait for your training & flight!
Great video. Actual hardware is a great teaching/learning tool. Especially when you see something you have only read about, in real life. And then realise how big - or small - that thing actually is. Turbo pumps are a classic example of something generating astronomical power out of such a tiny package.
Ariane 1 engine was using water to cool down gas generator exhaust, as gas generator was burning stoichiometric. Thats what this third small pump was doing.
This is actually around the corner from where I live. I’ve been walking around this engine trying to figure it out 😅 There aren’t many other rocket engines you can walk around like this in NL. Love seeing you explore this engine!
Ok, you just gave me one reason to got to the Netherlands with the kdis. Now I only have to figure out when. But this museum looks absolutely amazing. Thanks for the great video, Tim. It's amazing to watch your progress trough rocket tech. Really impressive.
I absolutely love this! Tim doing unknown rocket engine analysis is so educational. I love how he pieces it together and isn’t scared to say something wrong. Please keep doing this. This is the core of your channel, bringing space down to Earth for everyday people.
When you look at the incredible engineering, complexity, machining, welding and exotic materials that go into a single rocket engine, it’s absolutely INSANE to me that up until recently we essentially threw multiples of them away with EVERY launch.
Hey Tim , some point back in time , indian scientists were called to work on the Viking engine . It was a agreement of providing scientists to work and help develop this engine . Scientist prof Nambi narayan was one of them who after coming to India built the same Viking engine and went for testing the same engine in French test stand . Today the same Viking engine in india is called Vikas engine and is the workhorse of the ISRO . Some industrial partner's such as MTAR technologies were people who went with the scientists to work for the French . Now to date mtar technologies is responsible for manufacturing and certifying the vikas engine used on pslv and gslv rockets of India . This was just a small info I knew about , thought to share the same .
Its so incredible the size of the piping compared to the immense amount of propellants moved through the system per second. Great video Tim thank you ✌🚀
So the second engine uses a sort of 'steam generator' instead of just combustion gasses. I suppose it uses less fuel/oxidizer that way, but of course you have the complication of water tank/ pump system. Pretty neat variation.
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.
It's fun to watch Tim's self deprecating manner as he gets it right time after time. He knows more about these engines than 99% of visitors, while claiming he knows nothing.
Dude !!! Hope you had a nice and good time in the Netherlands!! Nice video like always!! I enjoy watching your videos much and learn alot of it, wanna thank you for that I person .. too bad i didn't know you were there haha else I shaked your hand!
The turbine in the Viking 2 is an axial turbine which is what is used in all modern aviation jet engines.Generally speaking, as flow enters the turbine section it first encounter inlet guid vanes (often incorrectly called stators), then encounter the rotors (if more than one turbine is used there are stators in between each rotor), then exits via outlet guide vanes (often incorrectly called stators). If this is the case here then your labeling is wrong. However, the geometry looks a little off for this to be the case to me. Do you know how many turbines are on the Viking 2? It would be unlikely for the engine not to have outlet guide vanes as this would induce rotation in downstream flow which is energetic and turbulent.
Awesome video Tim and Team, glad to see you guys did some video’s at Space Expo it is a small exhibit but a fun one we went there several times with my family. Did you guys have a time for the ESA/ESTEC facilities tour as well? Hope you enjoyed your time in the Netherlands
Im not sure if it was mentioned, for the last rocket engine. However, I think when you realized the steam driven turbo pump, it explains the two exhaust pipes. One is a steam exhaust and the other is the gas generator to create the steam! What an interesting system!
Neat exercise, similar to what I've done looking at engines here in Huntsville. Only wish that you had a laser pointer with you so we could see all the specific bits you were puzzling over. But nevertheless, cool video.
Tim, great video. I wonder if you could expand on the animated version of your previous engines talks and link them more directly to the actual hardware? I realize there is a lot going on there but take us closer to your understanding.
16:46 the toroidal tank is for water injection to cool down the walls and gas generator! , also VIKAS engine of ISRO uses water injection as it is based on the Viking engine. Edit: oh, you figured it out! (22:46) 😅
This is such a cool video. Appreciation for any machine scales so well with how much you know about all the mechanisms that it employs and exploits and how well you can understand and explain them. Not only that, but it's a good test and tool for your knowledge of rocketry as well.
Brilliant off the cuff video Tim. Do you think that now you have scratched the surface of these engines that you will do a full deep dive on the history of the European rocket engine families? Would be an ace one me thinks.
I have been at the Space Expo, in my complex electric wheelchair, and a small boy thought I was part of the Space Expo, like a man in a moon-car! 🙂 So now when little children ask "what is that" (referring to my complex electric wheelchair) I tell them it is a moon-car 😁
Hi Tim. Thanks for the great video! Was fun exploring these engines with you and seeing your first impressions. With a spiral wound engine bell I would imagine that the smaller tube cross-section at the top would have an advantage for cooling. The smaller cross section would create higher coolant flow velocities and thus remove heat more quickly from the most critical area of the engine bell. Is this a correct assupmption?
Nothing wrong with looking at an engine you know nothing about and trying to reverse engineer it. It's a great way to check your knowledge of engine construction
All I know is they switched Ariane 5 to a Vulcain 2 later and Ariane 6 will have a Vulcain 2.1. Which sounded good at the time but now spaceX has a 350bar raptor 3 closed cycle methalox soon... we are quite literally being left in the dust.
I learned, if you are truly curious, you will find the correct answers by talking out a solution. Thought = talking. Thanks Tim, I know a lot about rockets due to your original engines videos and some research after that.
17:50 - The sign was wrong in 2019, I told them it was wrong, they said they'd fix it.

This was surprisingly awesome. Thanks, Tim, for taking the risk to talk about engines that you aren't familiar with.
Rotors and the stators also maintain the velocity while increasing the pressure. Currently in turbine operation classes for A&P license

Tim love your channel. You could clam that your moustache grew faster from the Raptor dust at Boca 😉
Well done Tim, and thanks!
The pan around to the three stooges wearing the same hoodies was funnier than it should've been. Team Everyday Astronaut in the house haha
Nothing wrong with looking at an engine you know nothing about and trying to reverse engineer it. It's a great way to check your knowledge of engine construction
Is like seeing Sandy Munro of Rocket! Make more rocket review like this!
All I know is they switched Ariane 5 to a Vulcain 2 later and Ariane 6 will have a Vulcain 2.1. Which sounded good at the time but now spaceX has a 350bar raptor 3 closed cycle methalox soon... we are quite literally being left in the dust.
Raptor and Starship are currently high on their hype cycle, though.
@@harkonen1000000 lol for good reason…
Welcome to Europe Tim.
Great video
I learned, if you are truly curious, you will find the correct answers by talking out a solution. Thought = talking. Thanks Tim, I know a lot about rockets due to your original engines videos and some research after that.
"I'm pretty sure the sign is wrong" Epic!
This is amazing! I'd love to learn more about everything ESA made :D
