The tough part would be managing failures. If a motor on one side fails then they need to rebalance the stack so that it flies correctly. One could shut off a motor or gimbal the motors so that the resulting thrust vector drives the stack where it needs to go. There were analog controls in those days which were very good and very effective. The tough part would be polishing them, getting them to prevent problems and to respond to problems. The problem with analog controls is parts tolerance. You have to adjust to overcome it. It's tough. Today we use digital controls. Digital controls bring the feedbacks into software, where it is more easily managed and modeled.

The part that confuses me is why the Soviet engineers wasted time and money on a super heavy lift vehicle. A more sensible solution would be to send up multiple payloads, rendevous them in orbit, then send the resulting married ship to the Moon. Energia could put 100,000 pounds into orbit. It was composed of multiple strap on stages of something like a Proton rocket. The Saturn Five third stage weighed 271,000 pounds. I am not sure about the total mass of the mission, assume that they're the same. That's 540,000 pounds. About five of these vehicles. Make seven in case of failure. Both sides had orbital rendezvous figured out by the mid 1960s. Duplicating the US Command Module with the Soyuz manned capsule and the Lunar module, plus a "tug" to get them out of orbit and back to Earth was not an insurmountable problem. This idea of huge heavy lift vehicles to get the whole mission up in one big mass simplifies planning but makes the engineering a lot tougher. I do not understand why the Soviets wasted time and money on the N1. They got the Energia to work just fine.

Yes, the SSME (Space Shuttle Main Engines) RS-25 are closed cycle, but Fuel-rich While the Soviets went on the other side, rather than Fuel-rich They went Oxygen/Oxidizer-rich, which does need proper metal alloys to withstand the crazy high temps and other considerations with dealing of hot oxygen laden gas In the end though, both did good on their own While US did the Closed-cycle, Fuel-rich by using Liquid Hydrogen as fuel (which is much safer and more efficient, and will not cause blockages and soot in the engine.) The Russians did the Oxygen-rich Closed cycle because they used a much cheaper and abit more common fuel source, RP1/Kerosene If we use Fuel-rich closed-cycle with RP1/Kerosene, the engine will get plugged and may cause the engine to fail (because of the soot blocking the piping inside the engine, after the fuel pre-burner) At least now we can do a full-flow staged combustion, where we can both close the cycle on both the Oxidizer and the fuel, SpaceX Raptor Engine That uses Methane and LO2

American Lockheed and Northrop engineers concluded Petr Ufimtsev work and this Russian technology would be the future of the United States Air Force. The first Stealth aircraft in history was made in 1935 Russia. The Kozlov PS (Prozrachnyy Samolyot) an single AIR-4 was modified by Sergei G. Kozlov to demonstrate his technology of stealth or invisible aircraft for Russian air superiority. Covered with a transparent plastic sheeting and with interior structure and opaque parts painted silver, born the first stealth aircraft in the world. Ufimtsev was inspired in Kozlov concept of complete stealth or invisible technology but Ufimtsev not try an complete stealth or invisible concept as Kozlov, Ufimtsev focus in make a stealth or invisible technology only to radar. Sergei G. Kozlov believed the Russian Stealth technology must be stealth or invisible to everything including to the five sense organs of the human body. Aircraft and projects based in Petr Ufimtsev work and Russian stealth technology: Lockheed F-117 Nighthawk (Stealth attack aircraft) Northrop Grumman B-2 Spirit (Stealth bomber) Lockheed Martin F-22 Raptor (Stealth air superiority fighter) Lockheed Martin F-35 Lightning II (Stealth multirole fighter) Sukhoi OKB Sukhoi PAK FA T-50 (Stealth / Anti-Stealth / air superiority / multirole fighter) Sukhoi OKB and Hindustan Aeronautics Limited Sukhoi/HAL FGFA (Stealth Air superiority fighter) Tupolev OKB, Sukhoi (UAC) Tupolev PAK DA (Stealth supersonic strategic bomber) Russian Aircraft Corporation MiG MiG Skat (Stealth UCAV and A.I bomber) Chengdu Aircraft Industry Group Chengdu J-20 (Russian-Chinese Hybrid Stealth air superiority fighter / multirole combat aircraft)"

Funny emphasis on this, the whole "They were ahead of us in technology" theme. A Russian company had a visionary military/high-tech system that was promised to be a generation ahead, but which failed and failed, and got canceled. In retrospect it turns out that it really was visionary. This isn't a unique story. "Someone came up with a better way of doing it but before the bugs could be ironed out, conditions changed and it was terminated." The unusual thing with this story is that someone came along 20 years later and finished bringing it to market, and they all lived happily ever after. It's the story of the little rocket engine that could, not a lesson of some sort about national virtue and hubris.

+thepoultrypeople No, the vast majority (Possibly all) ICBMs in service today are solid-fuel devices. It is not safe to store Liquid fuel rockets fully fuelled for any length of time, and for an ICBM you need a quick response time. So the first generation of ICBMs used liquid fuel but needed to be fuelled before launch, which was a difficult procedure. Liquid fuel motors are generally used for Civilian launches due to their higher efficiency, but such rockets are fuelled on the pad immediately before launch.

The makers of this documentary understand the NK33 and the RD-180 are two very different engines right?
@la_potat60654 жыл бұрын
By the looks of things they do indeed understand it actually as 2 totally different engines. NK33 just recycles the preburner exhaust waste back into the combustion chamber at 15:00. Rather risky because potential soot formation from unburnt/incomplete combustion of preburner waste could clog up the fuel injector causing the engine to be destroyed. Perhaps that explains all the new filtration systems added on nk33 after the nk15 which uses the same cycle. No surprise that barely any rockets use this closed cycle due to how questionable the soot from the recycled preburner mixture is, being rather inferior to the oxidiser rich preburner staged combustion closed cycles from the RD-58 and onto the RD-180. RD-180 uses the more advanced staged combustion cycle where the entirety of the oxygen is sent to the preburner mixed with partial rp1 to vaporise the liquid oxygen in superheated gaseous form on an oxidier rich preburner 42:00. In effect having vaporised super heated oxygen (from the oxidiser rich preburner) in the combustion chamber to meet with the unvaporised RP-1 fuel results in the complete combustion of RP-1 fuel. Thus a clean burn is achieved with only CO2 and H20 for exhaust, and all the former soot formation problems are resolved. The requirement however was to produce a nickle super alloy metal that won't literally burst into flames in an oxidiser rich preburner environment.

@ 6:28 the NASA controller was saying that no American had the same amount of authority,responsibility or autonomy as the Russian space program controller, and that it took a whole bunch of American scientists/engineers to equate to the Russian approach, which is probably why Russia was so far ahead, one person pulling everything together is always better than having disparate groups of people trying to achieve the same goal but not working together on their aims. A huge difference between the two systems was that the USA had, or should have had a massive advantage in terms of technology having got most of the Nazi rocket scientists out of Germany and into America to build up what became NASA, and in my opinion that actually backfired on the USA, they relied on the V2 technology and the ex-Nazi scientist team to take the USAs programme forward, and so they were trying to advance technologies that were already as far advanced as they could be taken and only when that was realised did they start rethinking their approach and technologies in the space race, in the meantime the USSR had overtaken them by starting from scratch, or at least with a lesser reliance upon the Nazi rocket engineering, allowing them to advance quicker by exploring more than one option/design at a time. @ 11:16 the narration mentioned that Kusnetsov did not have any experience with rocket engines and that it was a gamble bringing him into the space programme, but really apart from Von Braun and his team nobody really had any experience of rocket propulsion on a large scale, and sometimes that can be an advantage, no preconceived idea of what a rocket looked like or how it worked, or you could say that he was not just going to take what was already accepted as the “gold standard” of rocket propulsion systems and try and make it do something it was not capable of doing. Think 💭 about the amount of money that both the USA and USSR ploughed into the space race and into the Cold War in general, and then think 💭 about what that money could have been used to do, things like building more schools 🏫 and hospitals 🏥, highway 🛣️ maintenance and construction, a better welfare and housing system, medical research into things like cancer and heart ❤️ disease, all these things would have benefited the citizens of their countries but that would never have been even thought 💭 about, at the time of the Cold War was so much more important to the political leadership of the individual countries and the world, at a time where money to “fight” the Cold War was almost limitless, especially in the USA 🇺🇸 and USSR, driven by a rational fear of WWIII, and the M.A.D scenario, which in my opinion was not driven by the general population of the world but by the political leadership’s insecurity and paranoia. Some people would say that without the Cold War we would probably be earthbound and so many other advances attributable directly to the Cold War would probably still be only a dream of inventors everywhere, and they would probably be correct.
