Explaining all KSP rocket engines! (Real life, cycles, cooling & MORE) 

"Energetic combustion event". I like that. Right up there with "Rapid unscheduled disassembly". 🤣

gg for keeping ksp2 alive, that was worth the wait

I remember a couple months ago you posted a sneak peak of this video on Reddit. It turned out great!

Thank you for all the nice comments and support so far!

This is genuinely really impressive work. Well done 🙏

You are really underrated, imo you're up there with Everyday Astronaut and Scott Manley. Awesome video!

Definitely make the SpaceX Merlin, and Raptor Video man! It would be super interesting to watch!

youre wayy too underrated fr your content is amazing

Very cool. I love seeing videos about rocket engines and KSP, and this is the best of both worlds. Great job!

Sick video, keep it up

Cool ass video, you need mote subs

You Made My Day. Well Maybe Cuz I'm Going on a Road Trip to Mont Blanc That's 9hrs...

The amount of research that must have took you is impressive. Great job with the illustrations because they helped me understand these types of engines and its a topic that usually gets me very confused. Keep it up! 👏

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.

I love using this video and KSP 2 to replicate the rocket engines in Juno: New Origins (Although unfortunately in KSP 2, there's no nuclear water engine)

cool video, pretty accurate

thank you man its exactly what i was looking for for along time

Was hyped to see a video on this topic!!

Keep it up dude this was amazing!

Holy shit. ONLY 889 SUBS? This is quality content, man! I looked at the sub and like count late into the video and expected at least 5k haha. This is great content, keep it up!

Im thrilled!

this was extremely informative, I learned many new things. thank you.

LOVE IT.

Just a minor correction 🤓, the terrier plume on (stock) waterfall is methalox, and the wolfhound (supposedly) is hydrolox (I think it looks more like methalox at sea level but the mod creator said that it was hydrolox...). But don't worry!!! Stock Waterfall Effects plumes were selected based on KSP performance rather than on their analogues... So you're still correct! Also... Nice video😄

Really well made video

This is sick! Could you do one on all the srbs too?

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). There is an amazing Video from Everyday Astronaut about how Rocket Engines work and its definetly worth it!

Good video, you explain it well

You should do air breathing engines next

Worth the wait, pretty good video

You might want to check out Restock revamping of those engines for more precise depiction of the plumbing in KSP 1

R.I.P. KSP2

Could you please also cover the KR-2L Rhino from the first game? I'm very curious how that thing works

Love the video man

i dont know existence of SABRE. Thank you.

Yipee new video

cool video

❤❤

very cool video however please never again compare thrust based engines to horsepower based engines no matter the topic, it's a huge shame considering the high quality of every other part of the video

mislleading tilte no solid engines explained

Sorry, but it's Lr, not XLR

the poodle is the transtage engine, drago was ranting about this and you addressed none of it
