RL10 Chart

RL10 Family Tree Chart
Includes every RL10 variant except for the Derivative, OTV and Category engines. Moved the post here because its probably better here.

For a more detailed look, see the attached PDF below.

Will you add the derivatives someday?

I will now have nightmares beacuse of the RL10CX-3EL

That's transphobic why would you say that

 

[QMSP]

Ok, they might as well give the the later ones different names because they look nothing like the original RL-10

They still have the RL10 turbopump and valves, only the nozzle is changed because its 3D printed.

Why do they even need so many of these, the original was from like the 1960’s, why can’t they just make an original engine? It would be more efficient due to technological improvements

Well, the RL10 keeps getting used because of its extreme reliability. It's heritage is also extensive, giving rocket and launch vehicle companies some peace of mind concerning the engine reliability and the reduced need for extensive testing.

The RL10-II, IIA, IIB, IIC, III, IIIA, IIIB and IIIC as well as the Category II and IV engines just have too little info to be reasonable on the chart. All I know is that the IIB is a version of the A-3-3A. I don't know the relationships between them and the other engines, except for the fact they were all considered for the Orbit Transfer Vehicle studies.

If you want a more efficient engine you're looking at NTP, and would you look at that...

Spoiler

RL10 derived NTR!

 

[TheMacTester]

where is the RL-10 A2

I could add that as a spin-off of the RL10B-2

where is the RL-10 A2

I don't know. They didn't designate one I guess.

It's Commercial Trans

Short for "Commercial Transportation." It was meant to be significantly cheaper so that commercial NASA and Aerojet partners can use it without draining their money in the first launch.

I was referring to the giant nozzle

 

[TheMacTester]

I was referring to the giant nozzle

you could say its... massive

 

[TheMacTester]

can you make the RL9

 

[Lemniscate Biscuit]

can you make the RL9

Give me some references and the thrust, mass and efficiency.

I think I've already asked about this one (A while ago), but would you consider the RL-60 for the Redux? I found a little paper that has some nice photos and info. It was made to be roughly the same dimensions as the RL10B-2 for installation / design purposes. Don't think it's a direct derivative of the RL-10, but shares a lot of common aspects.

[TheMacTester]

is there a sea level Rl-10

 

[MonkeSpaceflight]

is there a sea level Rl-10

There is one included in the mod iirc. Used on the DC-X.

oh yeah, i remember that, it was in New Horizons

This is planned to be in the ACE mod since it isn't directly a RL10.
