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.
What gets me and overshadows the brilliant presentation is that so much engineering went into designing a weapon of mass destruction, likely other innocent human beings.
you take a small pressure vessel full of whatever amount of water you going to need you have an existing to drop and ignite thermite into your tank you have a pressure release valve at a certain point or I should say a certain pressure it will pop turning your pump and all you have is a very simplistic system wow
As a chief engineer that has designed numerous gas turbines, industrial turbines and turbopumps, it's scary how many features in the V2 are still being used today. I also greatly appreciate the amount of time and effort put into this video. The more you know, the more you appreciate how good this video is and how much research went into it.
Would like to thank you for this video. My V2 has been just standing in my driveway for years; with all of my neighbors laughing at me, saying "You'll never get that thing running!" Well with your video, they won't be laughing anymore!
WOW, what an incredibly deep dive into the V2 turbo pump, easily one of the most interesting engineering videos I've ever seen. Absolutely fantastic work.

Please Give us part 2 and Continue with the v2 series !! This is undoubtedly one of the top 5 best UA-cam science channels:) Thanks for Inspiring Me and Teaching Us So Much :)) PLEASE CONTINUE THIS SERIES!!!!!!!!! WAITING EAGERLY FOR PART 2 .
The concept of this pump alone is enough to be amazed at... but imagine the difficulty of making the pump that handled the fuels...in the 30's no less ! No CNC machines... All that work and precise engineering and care only to be blown to pieces at the end of its mission. Crazy
*1940ies. And it was made by Concentration Camp Prisoners. But being blown to Pieces after a few Minutes was/is the Destiny of literally all Rocket Engines until the RS-25 Space Shuttle Main Engine came up.
I think literally hundreds of V2’s rained down on England during WW2 so it’s probably not so hard to acquire V2 rocket parts in England. Just like it’s easy to find Samurai swords in the United States after the Japanese handed over hundreds of thousands of swords upon surrender to U.S officers who brought them all home to the US.
@@slimchance7335 - It wasn't hundreds, it was thousands. Something over 2,000 V2's were launched at England. Even more were launched against Antwerp in Belgium where the allies had major materiel depots. About 5,000 total were launched in anger.
@@slimchance7335 V2's were raining down on England at 5000 mph, I doubt there were any parts to be had. The Allies captured a shit ton of V2s after the war and like this guy said this turbo pump is on display in the museum at Peenemünde. Did you watch the video?
@@johnarnold893 hate to be that guy, but 5000 kph, 3300 mph top speed. It's not like a nuke where ground zero is vaporized, there will still be fragments, albeit small, lodged in the ground. He says while showing a piece, 'it's a bit grimy, but it was in the ground for 80 years.'
I am deeply impressed with the quality and extent of this video... but also on how entertaining the host it is! I am thoroughly enjoying it, one of the best technical videos I've watched on UA-cam. Outstanding - Thank you for producing it and sharing it with the world!
what a turbo pumped rush! hard to believe that i just watched almost 2 hours of intricate rocket science without feeling bored for even a second. i'm so looking forward to part 2!
I was interested in this video being a retired marine engineer sailing the 7 seas for most of my life. At first I started to feel that the method of teaching was kind of slow and methodical I was only really interested in the turbine but as the video went on and you discussed steam production along with excellent demonstrations of same, I was hooked, hook line and sinker. 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. Thank you very much for sharing and It is hard to imagine the amount of research you must have put into this topic and then share it with us. You have a gift Sir thank you once again.
i have to say, I have watched many many videos talking about how the fuel systems of rockets (modern and old) worked. and while i had enough understanding to comprehend the theory, i always felt like i still lacked a lot of understanding.... This video, if you are not scared off by the duration is absolutely amazing. 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. I almost skipped over this video and it would have been a bloody shame if i had.
Who could give this a thumbs down? You obviously know the subject intimately and are able to present the information clearly and confidently. Two thumbs up!
WoW you have put some work into this video, I am half way through it, and already you have given me insight into the working of rocket motors I didn't have 1 hour ago😀 Will continue tomorrow night
By "more than anyone should probably know", I meant because it is an arcane (but interesting) piece of history, that no one should probably know that much about such archaic technology. Definitely not threatened by Iran if the best they can do is 70 year old turbopumps.
@homomorphic are you forgetting the only thing that kept the space station alive after the shuttle was grounded was a warehouse full of ancient soviet (not even russian!) rocket engines that follow this design fairly closely? Its a engine that's half a century old, and still in frequent use Warhead and heatshield tech might be constantly worked on, but those old rocket engines just keep on trucking
What was it that somebody from NASA said when asked why their rockets were better than the Russians? "Our German scientists are much better than their German scientists..." :)
Good post. Koryolev (sp) was brilliant. He weren’t German the other reply mentioned Energia. That was an impressive beast. He was the Soviet’s VonBraun.
Near the end of the war, Von Braun and most of his team packed up and made their way west because they wanted to be captured by the Americans instead of the Soviets. That's why "our Germans [were] better than their Germans."
the structure of the explanation is great! the problems are described in detail and the solution is explained in steps. The level of detail in the explanations is crazy! Greetings from Germany- Great work!!
I'm impressed by the quality of this documentary. For such a long one about a pump, I thought I'd quickly get bored. But now, because of you I'll sleep much later than planned today and I'll be tired at work tomorrow. I'm looking forward to part 2.
I haven't subscribed to *anything* on UA-cam in about 10 years until now, this guy is the best presenter I've ever seen in here and now I actually understand how rockets work. Fantastic!!!! A bit of genuine humor smattered in, taking a step back in the flow here and there to make sure everything makes sense, the models and diagrams, some V2 launches I have never seen before and noticing little quirks in what went wrong. Incredible.
Hi and thanks for taking the time to post and thanks too for subscribing. Be sure to take a look at Turbopump Part 2, which looks at some surprising physical effects of the pump system on the rocket in flight. Best wishes A&NTV
This is truly one of the best videos that I've ever seen. I can understand how much work you've put into this and am very impressed. You are very talented in presenting technical details so they can be understood by anyone interested. I also like the "speed". It feels like someone takes the time to show these things especially to you. And I share Martin D A's opinion: That is not a blind clickbait but a wonderful science lesson! Please keep up the good work!
Excellent presentation. Every "UA-cam" director should watch this over and over and over before making their own video....then simply emulate the presentation technique.....and publish. It's got all the required "C" elements of quality communication.....clear, concise, correct, and complete.
... and that rhythmic thumping sound you can hear is the MI5/FBI (delete as appropriate) helicopter SWAT team hovering above your house. If there's a bold knock at the door make sure you're not holding a black hockey stick when you open it. KR RJD A&NTV
It might be the FBI asking for your help in winning the space race against the private space adventurers. Ask for the cute FBI agent phone number as a condition for giving your help (I saw that in Sneakers).
Parts shown seem like straightforwardly machinable parts. Cast aluminum and steel? Ok, we have drawings. Cannot obtain H2O2 at 80%, that's tightly controlled; Will Wheaton was building an H2O2 model rocket for a while (2010-ish) and ran into supply problems on it. Bearings are Auto-grade (none higher than 8000 rpm, certainly auto-store accessible). Problem is all the test runs, would make BIG noises, so best not do it in your apartment foyer or old lady Robbins in 2A will tirade on the super and you'll have to sit through another, "I will not create vengeance weapons in my apartment" lecture again. LOL.
Great job on this. Incredible look at actual V2 parts and breakdown of design principle. Amazing how little things have really changed. The V2 engine is the flathead Ford of the rocket engine world. Thank you!
It never occurred to me that there was a steam "engine" in the V2. The amount of detail you describe all the parts clearly shows the interest and dedication you have towards this subject - I have found myself glued to the chair . Great, great respect! A great thanks to all involved in creating and sharing this video to all of us! After watching this video and the one about the gyros I feel I want to see a V2 in person! It is so ironic that so much technology, money and human life was put in creating this rocket - just for the sake of war and vengeance!
It is sad... and ironic, yes. But we also wouldn't have made it into space or to the moon without the incentives of the cold war ICBM arms race. Unfortunately, war is a powerful motivator for technological progress... more powerful often than curiosity.
Waaw..super remarkable demonstration of V2 rocket working.I am really amazed by this...never seen any video putting so much serious effort to make V2 alive again.thank you so much for making such a wonderful video.Thanks a lot.
Fascinating engineering lecture. I once had the honor of meeting Dr. Von Braun whilesoaring sailplanes at Elmira, NY. He was a truly dedicated engineer and cordial to bewith. R.W. Ruppert, P.E.
Outstanding. Very well made. I wish I could find similar videos like this, in depth, educational, and importantly by someone who actually knows what they're talking about. With the algorithm changes I seem to only get the same round of documentaries or more often viral videos from someone who has read half a wikipedia article and feels qualified to teach.
Was happening to me, then I figured I had to give the algorithm something to work with. I broke out, and started watching things I didn't like but were vaguely connected to something I would like. Now I rule the algorithm! Example: Started clicking on a few poorly done "science fiction" videos, eventually go to the good stuff. Also gave me more space science and space history.
I found a bunch of channels that make 10 min vids on various topics I like(engineering, science, tech, military tech). I thought they were all unique and well researched, and decently presented. Then I noticed that many of them rehash the same stories, events, weird history, inventions. 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.
@@TheBozn Not with people like this, the guy who makes "Homemade Documentaries", "Everyday Astronaut", AronRa, and many others actually know what the hell they're talking about AND put so much effort into making truly great and incredibly informative videos despite the hit-seeking stupidities of Google and their latest algorithms.
You're the first one to actually take a V2 apart and explain how the V2, not just any rocket, was actually engineered. I eagerly await your next video!
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.
Absolutely the best instructional video ever presented on not only basic rocketry but specifically the V2/A4. A real masterpiece. However I have been waiting for over two years for PART 2!! Robert when are we going to be treated to the conclusion of this epic work? Please post part 2.......
Impress is an understatement, you have shown me so much more of Von Brauns Ideas and what made him important to Nasa despite his WW2 involvement, all credit to you and your team Thank you so much for the history Of The V2 rocket looking forward to watching more once again thanks to you.
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.
Interested information for sure. I worked at a power plant for 35 years including steam turbine, pumps ect .. Thanks for all of the work putting this video together.
Comprehensive, technical and thorough while being understandable and relateable...quite a feat to pull off all. Truely impressive presentation. Thank you..I look forward to future content.
Remarkable discussion on the A2/V2 turbo pump. Dr. Wernher Von Braun would be pleased with this level of explanation. 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 !
Thank you, that was very interesting to me (aeronautics engineer)! The fascination, effort and detail you put into the production of this video is very much appreciated!
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.
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?
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.
59:40 steam generator demonstration. This crude demo is really excellent. It's a few steps out on a rickety limb, but it paid off well. I've had some difficulty imagining how this system works in concert with the rest of the rocket engine, but with your elegantly simple design here, it's spelled out quite well. I'm glad you realized its importance as the starting (and sustaining) energy charge in this system and you came up with a simple way that we can clearly see the components at work. Well done.👏
Love the numerous mentions of companies "still trading". I bet they don't put "We built parts for the V2" in their brochures. They should do though. They were asked to do an engineering job, and they did it well.
Absolutely great video. The level of detail and effort is unbelievable. I'm a rocket engineer myself, and completely agree with a comment you made in an earlier video - V2 is a great case study. For anyone who likes a 'chronological' approach to learning things there is no better way to be introduced to concept of rocket engineering than studying the very first long range ballistic missile. Please continue the effort, can't wait for the next part. Also, really enjoy this long video documentary-like format. I am definitely going to share this with my coworker!
I have an OCD about detail. So, this video was Nirvana. Finally, I knew the V2 propulsion system details. I’ve no words to express my gratitude for this unsurpassable presentation.
What kind of guy geeks out on a technology from soooo long ago and further yet, recreates it in miniature then spends untold hours creating a video to put on UA-cam documenting and displaying it function? My kind of guy, that's who. Thank you for your time and effort on this project. EXCELLENT WORK MY FRIEND.
WOW, I thought I knew my rocket science before this, was I ever wrong! Amazing detail and I had not heard about the V2's ability to throttle itself, nor that it had three thrust settings effectively.
I'm really impressed with the research you've done. Also, that blanking plate at 23:29 was made only a couple of kilometres from where I live. Kind of crazy how widespread the manufacturing process for these things was.
Incredible amount of detail. Models, actual components and all the technical details and science behind it. This must be the culmination of years of work. Absolutely fantastic.
Watch Turbopump Part 2 now! ua-cam.com/video/CmTxAFY03fU/v-deo.html
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.

Yeah but the russians have totally embarrassed the west with rockets over the last 30 years
I guess the smarter German scientists were the ones who found a way to get captured by the Americans not the Russians. Natural selection.
This was an excellent explanation of the A4/V4 turbopump. Well done.
the structure of the explanation is great!
the problems are described in detail and the solution is explained in steps. The level of detail in the explanations is crazy! Greetings from Germany- Great work!!
I'm impressed by the quality of this documentary. For such a long one about a pump, I thought I'd quickly get bored. But now, because of you I'll sleep much later than planned today and I'll be tired at work tomorrow. I'm looking forward to part 2.
I haven't subscribed to *anything* on UA-cam in about 10 years until now, this guy is the best presenter I've ever seen in here and now I actually understand how rockets work. Fantastic!!!! A bit of genuine humor smattered in, taking a step back in the flow here and there to make sure everything makes sense, the models and diagrams, some V2 launches I have never seen before and noticing little quirks in what went wrong. Incredible.
Hi and thanks for taking the time to post and thanks too for subscribing. Be sure to take a look at Turbopump Part 2, which looks at some surprising physical effects of the pump system on the rocket in flight. Best wishes A&NTV
This is truly one of the best videos that I've ever seen. I can understand how much work you've put into this and am very impressed. You are very talented in presenting technical details so they can be understood by anyone interested. I also like the "speed". It feels like someone takes the time to show these things especially to you. And I share Martin D A's opinion: That is not a blind clickbait but a wonderful science lesson! Please keep up the good work!
Excellent presentation. Every "UA-cam" director should watch this over and over and over before making their own video....then simply emulate the presentation technique.....and publish. It's got all the required "C" elements of quality communication.....clear, concise, correct, and complete.
Finally a video series detailed enough I can build my own V-2 at home.

@@RocketPlanet The only controlled stuff in it would be propellants, reagents and the payload, no?
It might be the FBI asking for your help in winning the space race against the private space adventurers. Ask for the cute FBI agent phone number as a condition for giving your help (I saw that in Sneakers).

Parts shown seem like straightforwardly machinable parts. Cast aluminum and steel? Ok, we have drawings. Cannot obtain H2O2 at 80%, that's tightly controlled; Will Wheaton was building an H2O2 model rocket for a while (2010-ish) and ran into supply problems on it. Bearings are Auto-grade (none higher than 8000 rpm, certainly auto-store accessible). Problem is all the test runs, would make BIG noises, so best not do it in your apartment foyer or old lady Robbins in 2A will tirade on the super and you'll have to sit through another, "I will not create vengeance weapons in my apartment" lecture again. LOL.
This is one of the best produced and technical educational videos I've ever seen on UA-cam. Absolutely fantastic.
Great job on this. Incredible look at actual V2 parts and breakdown of design principle. Amazing how little things have really changed. The V2 engine is the flathead Ford of the rocket engine world.
Thank you!
thanks 75 yr olds 1st 1951 4 door flathead.
It never occurred to me that there was a steam "engine" in the V2. The amount of detail you describe all the parts clearly shows the interest and dedication you have towards this subject - I have found myself glued to the chair . Great, great respect! A great thanks to all involved in creating and sharing this video to all of us! After watching this video and the one about the gyros I feel I want to see a V2 in person! It is so ironic that so much technology, money and human life was put in creating this rocket - just for the sake of war and vengeance!
It is sad... and ironic, yes. But we also wouldn't have made it into space or to the moon without the incentives of the cold war ICBM arms race. Unfortunately, war is a powerful motivator for technological progress... more powerful often than curiosity.
I'm curious why did they use steam to turn the turbine; why not make it electric ?
All of yours videos (also about astronomy) are just pleasure to watch. Short, understandable explanations. Bravo.
This is one of the most fascinating videos I've ever seen.
My God that was deep. I do love the chicken feeder rocket engine part
Waaw..super remarkable demonstration of V2 rocket working.I am really amazed by this...never seen any video putting so much serious effort to make V2 alive again.thank you so much for making such a wonderful video.Thanks a lot.
Fascinating engineering lecture. I once had the honor of meeting Dr. Von Braun whilesoaring sailplanes at Elmira, NY. He was a truly dedicated engineer and cordial to bewith. R.W. Ruppert, P.E.
The killed some members of my family, don't be so proud. He was a Nazi,

Greetings from Australia
Outstanding. Very well made. I wish I could find similar videos like this, in depth, educational, and importantly by someone who actually knows what they're talking about. With the algorithm changes I seem to only get the same round of documentaries or more often viral videos from someone who has read half a wikipedia article and feels qualified to teach.
Was happening to me, then I figured I had to give the algorithm something to work with. I broke out, and started watching things I didn't like but were vaguely connected to something I would like.
Now I rule the algorithm!
Example: Started clicking on a few poorly done "science fiction" videos, eventually go to the good stuff. Also gave me more space science and space history.
Yeah, UA-cam is dead
I found a bunch of channels that make 10 min vids on various topics I like(engineering, science, tech, military tech). I thought they were all unique and well researched, and decently presented. Then I noticed that many of them rehash the same stories, events, weird history, inventions. 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.
@@TheBozn Not with people like this, the guy who makes "Homemade Documentaries", "Everyday Astronaut", AronRa, and many others actually know what the hell they're talking about AND put so much effort into making truly great and incredibly informative videos despite the hit-seeking stupidities of Google and their latest algorithms.
Agreed many crap documentaries by amateur idiots.
One of the best videos on a technical topic that I've ever seen, really. This 60's vintage rocket nerd thanks you.
You're the first one to actually take a V2 apart and explain how the V2, not just any rocket, was actually engineered. I eagerly await your next video!
Fantastic video! The best material about the rocket V-2! Waiting for the second part and continue to do 3d model for next parts)
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.
What an amazing lecture! Could not look away, despite the considerable detail. Nice work in making a for-the-ages keeper for engineering training.
This series of videos is amazing. a) the level of detail b) the excellent presentation c) the sheer excitement. Love it!
Excellent presentation! Far above and beyond any other explanation I've seen. Well done!
I just wanted to come back and watch this again. This was my first introduction into turbopumps and I'm very grateful.
Vielen Dank für die anschauliche Demonstration. Sehr gute Arbeit!
Translation from German: Thank you very much for the vivid demonstration. Very good work.
Absolutely the best instructional video ever presented on not only basic rocketry but specifically the V2/A4. A real masterpiece.
However I have been waiting for over two years for PART 2!!
Robert when are we going to be treated to the conclusion of this epic work?
Please post part 2.......
One of the best films I've ever seen.
If youre going to be nerdy then go big or go home, and this is going really big!!!
Loved it
Go big! Rockets all the way.
I believe this might be the greatest youtube video ever made. Well done and thanks for sharing your knowledge with us !
I can not thank You guys enough for producing such high quality content!
This is beyond awesome!! This channel’s playlist associated with the V-2 is an incredible treasure trove of information!!
Impress is an understatement, you have shown me so much more of Von Brauns Ideas and what made him important to Nasa despite his WW2 involvement, all credit to you and your team Thank you so much for the history Of The V2 rocket looking forward to watching more once again thanks to you.
Professor, brilliant presentation.....this is the type of super quality teaching we need in our high schools.
Many thanks
Incredible depth of research and amazing presentation. Thank you for this tremendous effort.
This is exactly what I’ve been trying to find for so long. Can’t tell you how thankful I am for the specific and detailed info
Wow! What a magnificent peace of work! Huge thanks!
Im so blown away what a time you must of had researching all of this !! i never learned so much from a video in my life great job !!!!!!!!
Such level of detail and deep knowledge reminds me the NTSB reports… no words to congratulate you.
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.
Superb presentation. Great in-depth explanations of the turbopump parts & operation.
Excellent! I've heard people mention rocket turbopumps many times, but never understood how they work. You are a fantastic teacher.
Excellent work. Clearly a passion for history and rockets! Thank you!
Interested information for sure. I worked at a power plant for 35 years including steam turbine, pumps ect ..
Thanks for all of the work putting this video together.
Wow, that was really detailed. When he started pulling out stuff he 3d printed, I was like watching Santa taking out gifts. So cool.
Way more in depth than i expected, awesome video.
Comprehensive, technical and thorough while being understandable and relateable...quite a feat to pull off all. Truely impressive presentation. Thank you..I look forward to future content.
It has taken65 years to find some one like you and your fantastic. attention to detail, now how can I contact you. John
Remarkable discussion on the A2/V2 turbo pump. Dr. Wernher Von Braun would be pleased with this level of explanation. 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 !
Thank you, that was very interesting to me (aeronautics engineer)! The fascination, effort and detail you put into the production of this video is very much appreciated!
Wow, just wow man! That was an education. I've leveled up, thank you!
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.
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?
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.
59:40 steam generator demonstration. This crude demo is really excellent. It's a few steps out on a rickety limb, but it paid off well. I've had some difficulty imagining how this system works in concert with the rest of the rocket engine, but with your elegantly simple design here, it's spelled out quite well. I'm glad you realized its importance as the starting (and sustaining) energy charge in this system and you came up with a simple way that we can clearly see the components at work. Well done.👏
This is very interesting and very well researched. Thank you for sharing!
just finished this vid.
I can honestly say that that 1 hour 50 minutes was better spent than watching the whole of Bridgerton. Many thanks.
Love the numerous mentions of companies "still trading". I bet they don't put "We built parts for the V2" in their brochures. They should do though. They were asked to do an engineering job, and they did it well.
...and for the manufacturing they used Jewish slave labor.
Absolutely great video. The level of detail and effort is unbelievable. I'm a rocket engineer myself, and completely agree with a comment you made in an earlier video - V2 is a great case study. For anyone who likes a 'chronological' approach to learning things there is no better way to be introduced to concept of rocket engineering than studying the very first long range ballistic missile.
Please continue the effort, can't wait for the next part. Also, really enjoy this long video documentary-like format. I am definitely going to share this with my coworker!
Wow! Extremely well done! Old school graphics were a real treat.
I have an OCD about detail. So, this video was Nirvana. Finally, I knew the V2 propulsion system details. I’ve no words to express my gratitude for this unsurpassable presentation.
This is like a professor delivering an amazing lecture, very high quality content! thanks a million.
What kind of guy geeks out on a technology from soooo long ago and further yet, recreates it in miniature then spends untold hours creating a video to put on UA-cam documenting and displaying it function?
My kind of guy, that's who.
Thank you for your time and effort on this project.
EXCELLENT WORK MY FRIEND.
WOW, I thought I knew my rocket science before this, was I ever wrong! Amazing detail and I had not heard about the V2's ability to throttle itself, nor that it had three thrust settings effectively.
Extremely well presented and explained development of the V2 turbo pump and why it is the heart of a liquid fuelled rocket.
this is insanely dense for a youtube content, well done!
I am so blown away by the engineering of something that was the first of its kind
Very informative :-), well presented
all my years never seen anyhting in depth on youtube like this very nice
I'm totally out of words, very very impressive. I really need you as a teacher :(
Keep it up!
Incredibly well done video. Excellent explanations and models.
Absolutely a gem of a video. Very impressive design, explained in an equally impressive video. Beautiful !
I have been looking for these information for over 3 years. Thank you! What a relief! I am celebrating this moment!
I'm really impressed with the research you've done. Also, that blanking plate at 23:29 was made only a couple of kilometres from where I live. Kind of crazy how widespread the manufacturing process for these things was.
Incredible amount of detail. Models, actual components and all the technical details and science behind it. This must be the culmination of years of work. Absolutely fantastic.
