Aerojet Rocketdyne recently delivered four RL10 upper stage engines to NASA’s Stennis Space Center that will help power NASA’s Space Launch System (SLS) rocket as it carries astronauts aboard the Orion spacecraft to deep space. These missions are part of NASA’s Artemis program, which will land the first woman and next man on the Moon.
The SLS Block 1 rocket will use one RL10B-2 engine, the same engine currently used by the Delta IV rocket, as a part of the interim cryogenic propulsion stage (ICPS). As the rocket evolves to a more powerful Block 1B configuration, an exploration upper stage (EUS) will be added. The EUS will use four RL10C-3 engines, and the upgraded rocket will send astronauts tens of thousands of miles beyond the moon to explore deep-space.
Aerojet Rocketdyne is under contract to deliver 10 RL10 engines to NASA to support the Artemis program. One of the four engines that were recently delivered will be used to support the Artemis II mission that will use the ICPS upper stage, while the other three are slated to support future Artemis missions aboard the EUS. Delivery of the remaining six engines will be completed by 2021.

I worked on the RL-10 in 1962-1963 at Pratt & Whitney Aircraft Company in West Palm Beach, Florida. Great engine, and still in use with Aerojet Rocketdyne.

I work for P&W at the (old name) Florida Research and Development Facility, and was born into a Pratt household. On the days work effing sucks, it’s videos like this that make me realize I am living a dream. I still remember the hand bent skirt tubes and LN2 crypto tests as a kid coming out here. Very cool, Af plant 74 (mama bear), the town of apix also good subjects related. The RL10 is still hand made here, albeit the guys over there just wear Aerojet badges.

Aerojet family member here. The early 1960s was a very exciting time to work at Aerojet. We were about to send men into space. Von Braun and some of the original astronauts would visit the plant and chat with the technicians, machinists and engineers.

@@_mikolaj_ RL 10 is efficient because it is a LOX / LH2 engine that by its nature is highly efficient. However the RL 10 is beastly expensive at around $38 Million a copy. It is a small engine with 24 klbs of thrust. Compare that to a Merlin 1D vac engine for $2.17 million per engine with 200 klbs of thrust. Many times AR has offered to update the RL 10 to modern manufacturing methods and state of the art technology. The government refused to fund. There is no question this 1950s technology engineering is grossly obsolete.

@donjones4719 4 жыл бұрын

@@WWeronko I agree, have been dismayed AR is still using this old tech. Also agree a stockholder owned rocket engine company isn't going to take on expensive development costs for the fun of it. But now we see their habit of waiting for govt funding to do *anything* has come around to bite them in the ass. Aerospace companies have self-funded new tech to make sure they're ahead of any competition - even in this field, competition occurs. SpaceX will put the Delta family almost out of business. Blue Origin almost got the contract for the upper stage engines of ULA's Vulcan. I'm guessing AR made a big price cut to compete against BO. Did read that AR started developing 3D printing for the RL10 nozzle, about 1-2 years ago. Yeah, after SpaceX and Rocket Lab were already printing major parts or entire engines. But AR sat around happy and sleepy with the status quo, charging an enormous markup for their engine. The Atlas V for Starliner needs 2 AR10s. At $72 million that's already the cost of an F9 launch and more. Not griping at you, but at the layers of folly of the old-line rocket companies. (Actually, I've heard many figures for the AR10 price, from below $25M to the $38M.)

@nuke9918 4 жыл бұрын

@@WWeronko first RL-10 doesn't cost 38 million a piece. Maybe that was the A version back in the day. Since than AJR has constantly improved RL-10 design and the latest version that is supposed to fly on SLS, Vulcan and also Omega, uses extensively 3D printed parts, including the combustion chamber and an overall simplified design that uses less pieces to complete the engine. The RL-10 CX has beaten the BE-3U in bidding competitions 3 times. It's likely that the cost for ULA and NGIS was around 4-5 million a piece. SLS has a contract for 10 of them at 200 million. That's makes 20 million per engine, however the contract value also includes modifications, testing and certification of the engine for human rating, so that's inflates the cost figures by quite a bit. Human rating is a costly thing. Second thrust is not the main means of comparison for upper stages. RL-10 is supposed to push payloads from LEO to high energy orbits. So it needs efficiency. That's why it has such amazing ISP (465 sec). Merlin Vacuum has more thrust because it's supposed to push a big second stage to orbit from low velocity (due SPX needs of first stage recovery), so it has to have a ton of thrust. However when going to high energy orbit the low ISP of the merlin 1D vacuum of 345 sec puts the Falcon family at great disadvantage against rockets that uses RL-10s in the upper stage. That's why an Atlas 421 while murdered in LEO performance, already overtakes F9 on TLI payload

They're using 55 year old tech because there isn't a way to significantly improve it. You can't increase the efficiency of the combustion, it's already using a perfectly optimized nozzle, and the turbopumps all work perfectly well. The RL-10 is the single most efficient rocket engine produced *ever*, and that's why they're using it.
