RD-810 is a Ukrainian derivative of Russian engine RD-120. Russian RD-120 is developed in 1990 and China got this technology in 1990s from Russia. In 1995 USA got this engine and updated for there requirements. In 2006 government of India got blueprints of RD-810 engine from Ukraine. For people wondering yes it is 30 year old engine technology and it depends on ISRO to innovate it just like China and USA did. China got this technology in 1990s and created Yf engines in 2007 which power all LONG MARCH family rockets.

[@yangshujian]

Not quite correct for the Chinese YF part. All Chinese liquid engines are named YF-XXX, including those hypergolic ones developed during 1970s, like YF-20, which is still powering the Long March 2/3/4 families today. The Chinese engine derived from RD-120 is called YF-100, which is being used on Long March 5/6/7/8, namely the "new generation Long March rockets" only. Today the majority of the Chinese launches are still completed by rockets powered by hypergolic engines, just like Vikas. Only about 15% of China's annual launches use the clean YF-100 engines. Yet they are all used to launch the heaviest payloads, like space station modules, cargo spacecrafts, or advanced communication satellites, all of which require high energy that the traditional engines can't handle.

[@JohnSmith-vn8dm]

The YF-115 is also closely derived from the RD-120. I didn't know the US had any updated RD-120 though, are you sure about that? I know they bought some RD-120s for the Atlas 3.

Great video and explanation. You mentioned about metallurgy. I know this engine and Kaveri are totally different but can metallurgy knowledge be transferred to Kaveri team or it is completely different? 😬

[@arunramachandran5012]

The correct term is material science and metallurgy is one part of it. Yes, one of the biggest challenges in engineering today IS material science but nobody is giving it the due focus and value. Even Elon Musk routinely says that for SpaceX and Tesla, the biggest challenge is material science and his advice to young engineers is to focus on that field. Yes, some of the material science expertise can absolutely be transferred from the work done on Kaveri. But obviously, some of the specs and engineering requirements are also going to be brand new.

Material science is a well funded (by market and governemnts) multi trillion dollar Industry. It has been in existence since at least 1 lakh years. It has been a separate field of study since the first half of 20th century. It touches every aspect of your life and it is everywhere, even inside your pussy. Every year thousands of new materials get developed for millions of applications. People are always in the search of the new miracle material with desirable properties. Some examples of big breakthroughs in material science are plant fiber based fabric, processed leather, refined copper and silver, Ceramics, Steel, Aluminium (in 20th century), Kevelar, Plastic, Graphene, rubber, bitumen, refined silicon, body friendly materials, high melting point alloys, ultralight alloys, ultralight tiles, silicon nitride, high temperature superconductors.

[@Dennis56781000]

@@newworld2086 Someone once commented that Jet engines are far more sophisticated than Rocket engines. This is due to the fact that Jet engines have moving parts and require a very high degree of engineering and manufacturing expertise. That's why you'll see Rocket engine tech proliferating while Jet engine tech is a closely guarded secret that no one shares. Kaveri would require 5-10 billion dollars and a decade to function tbh. You will be amazed to know we spent only 2000 crore over a span of 30 years on Kaveri which is peanuts and it's a miracle that folks at GTRE still churned out a working engine.

most important development

[@manishsramon]

Whoever is questioning ISRO's decision to derive their preliminary design out of RD series. Most semi cryo sea-level engines in the world are of Soviet Origin. SpaceX's Raptor is also a Soviet Derivative in its preliminary design (RD180), which Elon himself admitted in an old video-look for it. It's just not considered wise to start everythig from scratch. Co-axial Swirl Injector technology is what made Soviets pioneers of Liquid Propellant engines while on the other hand in NASA was busy trying perfecting not so practical impinging injector design (In which they eventually did succeed). After the collapse USSR, NASA somehow managed to got that Soviet technology patented in their own names (Probably by buying some people at the Energomash I guess). Now there are literally enjoying loyalities on Soviets achievements. Well, their (NASA) story is that they invested ~$3 Billion to perfect that technology used in RD-180 cluster that later got incorporated in ULA's Atlas-V rocket.

[@sidharthcs2110]

Ther Merlin is definitely not related to RD 180. RD 180 is a closed cycle design

[@Phantom369-h3i]

False, Elon just praised the rd-180 for its high chamber pressure and thrust to weight ratio and for making the metallurgy work out for LOX rich engines. He never said that raptor is a derivative of rd-180.

It will be eagerly awaited, and telecast as well - an easy deal to telecast, it is Earth where the drop-off happens and doesn't have to be animated. OSIRIS-REx after dropping it off, will go on to do other missions.

4:25, If we get SC-120 then ADMIRE Test is very near, Because Merlin-1D is same engine as Vikas but with different fuel, Grasshopper was tested with Merlin-1D which is similar to SC-120.

[@azadahamed9677]

Marlin 1D and vikas are completely different engines. They use different fuels, marlin is regeneratively cooled where vikas is water cooled, the expansion ratio , chamber pressure, specific impulse all are better in marlin. And using hypergolic fuel instead of cryogenic or semi cryogenic fuel is way easier. So both are not the same.

[@prakhargupta3104]

I think another reason for chill down is to prevent cavitation during engine start when cold liquid touches hot surface and perhaps the primary reason.
