Yo Zenoth Idk if you would see this comment but the LM Decent engine has a IRL counter part. The TWR TR-201 which is the the LM Decent engine but simplified for use as a second stage on the early delta 1000-5000 rockets. Both the LM Decent Engine and the TWR TR-201 were pressure fed so you can assure yourself safe on the info you put out

Thoughts and corrections: I've never played KSP 2, so I can't really comment on those. -The Poodle was probably inspired by the dual engine configuration on the original centaur stage, now making a return with Centaur V and the dual engine Common Centaur for CST-100 flights. -the RS-25 powerhead is an absolutely messy marvel. it has FIVE pumps, most operating independently of each other. The fuel preburner runs the HPFTP, after which fuel is routed through the regen channels, where some is tapped off and used expander style to run the LPFTP, before going to the MCC. The Oxygen preburner powers the HPOTP, and a small kick pump which runs on the same shaft as the HPOTP to raise the pressure of a little bit of oxidizer to route to both preburners.(These are the ONLY pumps that run on the same shaft in the engine). Some oxygen coming out of the HPOTP is routed through a hydraulic turbine (this uses liquid instead of gas, think about what they use in hydroelectric dams) which is used to power the LPOTP. -The Skipper, for me has always been whatever I want it to be. I've always seen it as a generic kerolox vacuum engine, used for a variety of purposes, but most often I've seen it used as an Mvac stand in. -The plumes for the Cheetah and Wolfhound have always made me headcannon those as hydrolox engines, also because they have rediculously high ISP, even if their real life counterparts ran on hypergols. I have considered going into waterfall and adjusting the plumes, but the ISP is still way too high. (General formula for converting real ISPs into KSP ones, if real ISP is > 300, subtract 300, divide by 2, then add 300. For example, the vector. 451 - 300 = 151 151/2 = 75.5 ~~ 76 = 376. For balance reasons, the normal vector doesn't have this, but the Wolfhound and Cheetah are way up there.) -The J-2X was considered for the SLS Block 2 upper stage, as where the Pyrios boosters, in the PDR, however, in the CDR, they really solidified SLS's purpose as being meant for deep space, and that meant everything that would detract from that ability was out the window. The old EDS would have gotten slightly less payload to TLI than the EUS, and the new BOLE boosters have their thrust profiled specifically to give better payload capacity to deep space compared to the RSRMVs and Pyrios. Plus, the new GSE, new ML required, etc just wouldn't make liquid boosters worthwhile unless you had a high enough flight rate that the big solids damaging the flame trench was a cause for concern. -The Terrier does make me think LMDE, however, the plume makes me think it's running Methalox. The LMAE did not have any radiatively cooled segments, it was entirely ablatively cooled since it was partially stuck up in the LM, and there would be no place to radiate the heat away to. It also could not gimbal or restart.
@zenothksp
@zenothksp 5 ай бұрын
Awesome! I like seeing other peoples thoughts on the engines too. I did consider the Poodle as the Centaur but in game the plumbing looked off, and according to some people it is the transstage on the Titan-IIIC. For the plumes of Terrier, Cheetah and Wolfhound I did think they looked different to the RS-25/Vector which is why I put the fuels as hypergol (irl they are), but the different plumes are probably due to different expansion ratios. And sadly in KSP the performance (ISP/Thrust) is all over the place compared to real engines, so I didn't really look into that when deciding the propellants.

I think the Skipper engine is loosely based on the J-2, as that is the only comparable upper stage engine. The Poodle is probably based on the RL-10, but when the devs saw the comically large nozzle on the RL-10B2, they thought about making it comically small, it was also the most efficient chemical engine for a long time, just like the RL-10B2. The making History DLC of course messed that all up with power creeping the hell out of the poodle and adding the Skiff Engine.
@benwaffleiron
@benwaffleiron 5 ай бұрын
i think it makes sense that the terrier, swivel, reliant, and poodle engines seem a bit confusing, since i think they were the first rocket engines added to the game in ksp 1, and thus weren't really based on any one particular real-life engine

small correction: the fuel that cools down the Nozzle are verticle as the wall, not on the nozzle wall. You said the supportrings around the nozzle cool it, but they are only for stability. The Channels where the fuel runs through the wall and IS the wall, on some engines you can see these tubes (for example: F1).

@@zenothksp fair enough, thanks for the explanation. I haven't watched the whole video yet because I'm playing KSP1 and KSP2 engine knowledge isn't of that much use to me... I'm really sad about the KSP2 situation though. I bought the game for full price on release day (back in early-access), and to say I'm disappointed would be a huge understatement :/ I was so hyped for the game but after a few hours I just stopped playing it and installed KSP1 back on and modded it instead. I made about 5 crafts and every single one got somehow corrupted by bugs, my Kerbals despawned, my landers sinked beneath the ground, and one spaceship just... disappeared from orbit. I wish I could have enjoyed the game, but I just couldn't bear myself to spend another 5 hours building a ship, just to see it despawned and/or swallowed by the ground on craft loading (I just went to tracking center, then went to control the craft and boom - it was beneath the ground, on it's way to the core... on next reload of the craft it no longer existed.) Sad story indeed :/ KSP2 is dead, long live KSP.
