Typo at 7:34 : as I say, at launch, the four boosters of Soyuz are at 100%, the central one is at 70%. Speech is correct, text isn't.
This video tries to decipher some of the things we see when we watch a rocket launch, more precisely when looking at the flames coming out of the rocket nozzle during the first seconds of the flight. The second episode will focus on the rest of the flight.

this reminds me of an anecdote form the Cuban crisis times. When the soviets were supplying Cuba with mid range nuclear rockets, they were unloading them just on shores for the Cubans to later pick up and transfer. So, the US government invested quite a lot to develop a heli, that could lift the rockets one by one and deliver them to an american ship nearby. After this project was ready to start, the responce of the Soviets was to just chain the rockets in pairs. If it works simple, you'd better not to look for Murphy's laws in action for your expensive project

I've been a space geek for over 30 years now, and I still learned a ton during this video. Well put together! Don't worry about the French accent, I'm from Canada, I'm used to it ;-) One thing about the F-1 engine that has fascinated me from day one is the black smudge around the exhaust. It is the result of the turbopump exhaust passing through liquid helium and liquid oxygen heat exchanger coils. The resultant helium and oxygen gas are used for fuel and LOX tank pressurization, etc, and the now much cooler turbo exhaust gases pass into a manifold, which then vents it inside the nozzle extension. This boundary layer cools the nozzle extension, since the nozzle, throat, and combustion chamber are regeneratively cooled. Passive cooling for the nozzle extension, active cooling for the rest of it. (The heat exchanger is the bottom half of the cylinder thing next to each engine bell, and the manifold is the thick ring around the nozzle. A gas generator downstream of a gas generator.) . Keep up the great work! I will be watching part 2 next.

Amazingly detailed, accurate and knowledgeable rendition of the complexities of a rocket engine that can be discerned simply by looking at the exhaust. Thank you for this very educational and useful video. I'm a native English speaker and I found two features of KZfaq that we can now use in order to mitigate any problem because of the wonderful French accent; i.e., the closed caption button (cc) that gives the English as text at the bottom of the screen, and the 75% playback speed available from the "nut shaped" settings button. So thanks again French Space Guy!! A friend of mine was a professor at a well known university here in the states in Aerospace Engineering and he regularly recommended this video series to his students.

Really, really good. I'm going to show my kids this video, but I'll have to stop it many times along the way. You switch from one vehicle to another very quickly. I know 70% of these vehicles, so the pace is great for me. It's tougher for folks who know few of them. Great choice of subject material. Liftoff is the most viscerally engaging part of most rocket missions... except landing, and there isn't much variety there.

Found this video recommended by an "AIAA Engage" forum contributor. Fantastic! Comments here look very positive. Note for viewers challenged by the pace or accent, try 0.75 speed at the KZfaq settings menu, English subtitle setting is also available here. This helped on my second viewing of a few phenomena. No need for the author to adjust anything.
