A4 / V2 Rocket in detail: Turbopump

[@RocketPlanet]

Watch Turbopump Part 2 now! kzbin.info/www/bejne/eZ63qXR8jpVmnLc

[@typxxilps]

time to add the 2nd part here 22:10 shows Rieber which is a famous manufacturer of stainless steel kitchen sinks with a huge variety of products, very accurate parts and kits which you will appreciate if you build the kitchen on your own or need a special one with unusual dimensions or proportions. Frankenthal is a city north of Ludwigshafen which will not help the most people until they hear that Ludwigshafen is more or less BASF and that all the companies from Frankenthal have been suppliers of BASF just 10 km south where BASF needed all the parts and tubes, controls, pressure things for their chemical plant that were required for the rocket. Therefore Frankenthal companies = BASF suppliers and therefore the best spot in germany to find anything you might need that works under high pressure and in chemical reactions. Ask BASF and you will get an answer where to find a proper supplier.

Thank you very much for these videos. I'm impressed. It is not often that someone approaches the topic so carefully, substantively and professionally. Unfortunately, most of the videos about technology on the internet are rather popularizing in style. Almost no one wants to go into details. Very few people have the appropriate knowledge and understanding of the topic. And the desire to share this knowledge with others.

You would have to be careful because just a little gaseous nitrogen would heat the liquid oxygen and increase pressure in the LOX tank. But I’ve thought of this as well.

That was a brilliant explanation of the workings of these terror machines in terms of propulsion and I very much look forward to the next part. I am pleased I stayed the course because your method of teaching left me with and enormous amount of information. The educational conduct along with easy to understand explanations and your easy manner. I was trained before going to sea in an British Naval dockyard ( HMS Devonport) as an engine fitter and turner. We were taught the old school way, there was no CNC or anything as fancy in those days. So I can fully understand the machining principles in the making of these parts very tight tolerance parts.

In 1957, for a junior chemistry science fair project, I made a crude version of this steam generator to drive a little turbine I made. A quart paint can had a smaller can connected through the lid with a 1/4" quarter turn valve. A pressure equalization tube connected the paint can to the top of the upper can that contained the hydrogen peroxide. I put potassium permanganate inside the paint can and opened the valve to generate steam that spun the 4" diameter.

[@yellowboy1866]

A very interesting video, from a retired marine engineer in NZ. The turbine blades, i have seen the exact same types on a large marine engine of German make. Except they were longer and had a peg on the top with a band riveted to them. I was told that they had been hand forged and dressed. This turbine i was repairing, to keep the ferry running, as a new one was being souced from the manurfacturers. Its thrust bearing had run, due to debri blocking oil ways. Three of the stages had touched. Lots of mangled metal. They asked us to try and recover the longer blades, as they said that they could be reused for shorter blades.

I feel like in just this 2 hours of video I have developed a far deeper, richer understanding of how these pumps actually work. to a degree that i feel confident i could build my own low function model of one. a far far deeper understanding than the many hours invested elsewhere has given me. Thankyou for putting together this breakdown and walkthrough. you do a fantastic job of explaining complex systems in simple terms, and your visual walkthrough along side it is invaluable.

They were more or less interchangeable, and I cant tell who is copying who other than looking at who posted the earliest vid on a topic. They really gloss over many of the details and you end up with the same summary overview without ever seeing the details or big picture. These channels have millions of subs, and i know other people have noticed this same phenomenon from reading the comments, like this thread starter above. It is indeed a flawed characteristic of the search/recommended algorithm. I guess I need to watch more stuff that doesn't seem the most appealing, so I can find stuff that is.

What if Dr. Von Braun was a guest commentator during this episode that would just be awesome. Can't wait for the other videos to come out. Those engineers were just freaking clever and smart. It just amazes me the level of complexity in just this one part of a whole system components. What id someone did this for the Saturn F1 engine or the SSME that would be great.

They should off hang that Nazi . Strange that the german attacks with the v1 against the brits is turnend into such a nice engineering wonder . Same Nazi,s rule the world now but today they speak english !

@@egongefferie9194 Sounds like you love the CCP, good luck wit them !

[@thedevilinthecircuit1414]

Fantastic breakdown. The thing to remember about any pump is this: it does not create pressure; it creates flow. A restriction in the flow path is what generates pressure in the system.

[@FranktheDachshund]

Wow! Extremely well done! Old school graphics were a real treat.

[@chronosschiron]

all my years never seen anyhting in depth on youtube like this very nice

[@longyang-funvideo]

This is like a professor delivering an amazing lecture, very high quality content! thanks a million.

[@kingcosworth2643]

All this gorgeous engineering just to get blown up at the other end, incredible.

[@channelrafy]

"a rapid, unscheduled disassembly..." hahahaha

[@basila33]

soviet engineers used collocation "opening of the combustion chamber" instead of simple "explosion" to not scare generals :)

[@wc8932]

Lay person translation: "Massive Explosion of Rocket" lol

RUD

[@lsdlocks4673]

Like a KIA wreck - Killed In Action LOL.. It was surprising to discover that rocket science can be boiled down to steam engines LOL ..

[@danielmarshall4587]

yes that brought me a smile as well.

[@sunkid86]

I have been looking for these information for over 3 years. Thank you! What a relief! I am celebrating this moment!

[@philorkill]

This is very interesting and very well researched. Thank you for sharing!

[@walterthorne4819]

Professor, brilliant presentation.....this is the type of super quality teaching we need in our high schools. Many thanks

[@ginalee813]

Absolutely a gem of a video. Very impressive design, explained in an equally impressive video. Beautiful !

[@adrianc9692]

THANK YOU for this video. Finding detailed information on ANY turbopump is difficult because it tends to be classified. As an engineering student with a passion for aerospace, I applaud you for making this video.

[@MoritzvonSchweinitz]

What a beautiful complete geek-out about such a specialized slightly random topic! I love learning things like the different vibration modes of a V2 fuel tank and its fuel turbopump, and how how this was fixed by simply moving a pipe. I wonder how they detected that vibration/resonance problem, though? I doubt they had decent sensors?

[@NorceCodine]

Every time a rocket exploded after launch they carefully collected all the parts and looked at the type of fractures. Vibration leaves a characteristic fracture like a fingerprint. Quality control was the key why the Germans could build 900 rockets a months and out of that number 900 have functioned, while the Russians built 10 N-1 moon rockets and all 10 exploded.

[@dayradebaugh]

Incredibly well done video. Excellent explanations and models.

[@stevefink6000]

Wow, just wow man! That was an education. I've leveled up, thank you!

[@TimMartinDesign]

My Dad's RZ2 was a second generation copy of this ... great video - thank you

[@3334alfieslater]

Never clicked a link so fast!!!! Where have you been!

[@hermannkorner3212]

The duration of the clip first scared me off, but now i'm glad i watched- very worth while! Maybe split into 3-4 episodes?

[@ThiagoBouzan]

this is insanely dense for a youtube content, well done!

[@SuzukiBanditcc]

I believe this might be the greatest youtube video ever made. Well done and thanks for sharing your knowledge with us !

[@geronimo5537]

If more videos like this come out then this would be an easy one million sub channel. As for the part failure of the hole. I imagine that due to the massive amount of slave labor used to build V2 rockets that this was one of those small but vital sabotage locations that would still pass inspection.

[@MoMadNU]

Since it was designed for backflow venting and not as an injector, it probably didn't matter too much that it was partially blocked.
