- Explaining all KSP rocket engines! (Real life, cycles, cooling & MORE)
In Kerbal Space Program, you can just click a rocket engine under a fuel tank, press the space bar, and you go up. In real life, it is not nearly that easy. Today, we will be covering all the liquid fueled rocket engines in both Kerbal Space Program (KSP) games, and we will be learning about their real life counterparts, engine cycles, cooling mechanisms, and much, much more. This is my first Kerbal Rocket Science video.

if youre a rocket scientist or an engineering enthusiast who wants to learn how engine propulsion works, this video is for you
"Energetic combustion event". I like that. Right up there with "Rapid unscheduled disassembly". 🤣
gg for keeping ksp2 alive, that was worth the wait
Tbh the only reason i have any ksp2 footage in here is because video production started before the layoffs were announced
Thank you for all the nice comments and support so far!
This is genuinely really impressive work. Well done 🙏
Thank you very much!
Agree
I remember a couple months ago you posted a sneak peak of this video on Reddit. It turned out great!
R.I.P. KSP2
Yep, very disappointed but not surprised
You are really underrated, imo you're up there with Everyday Astronaut and Scott Manley. Awesome video!
Thank you so much! I'm honoured to be up there with my inspirations 😅
youre wayy too underrated fr your content is amazing
Thanks!
i agree with you
Definitely make the SpaceX Merlin, and Raptor Video man! It would be super interesting to watch!
@nitrorific7211 Definitely thinking about it, I'll probably do it sometime soon
Found you on Reddit and didn’t have high hopes then I clicked and this is up to par with the greats, very amazed
@@Tw_space Thanks!
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
You Made My Day.
Well Maybe Cuz I'm Going on a Road Trip to Mont Blanc That's 9hrs...
Glad to hear, and enjoy your trip at Mont Blanc!
@@zenothksp i made it! ill go to bed soon and explore. Thank you for the kind reply!
Sick video, keep it up
Thanks, will do!
Cool ass video, you need mote subs
Thanks!
thank you man its exactly what i was looking for for along time
Hope you enjoyed it
Was hyped to see a video on this topic!!
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.
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.
Keep it up dude this was amazing!
Thank you so much!
"This guy has a dutch accent"
*picture at the Space Expo in Noordwijk*
Also the first engine I saw :D.
Coolest museum in Europe!
cool video, pretty accurate
i. Adored. this. video. Amazingly well done!
Thank you very much!
Rocket Science? Kerbal Space Program? Using illustrations ?
THIS IS HEAVEN FOR ME
Good job on the video. Deserve more attention especially from KSP and all other communities
@@PERNTNOTFOUND Thanks! That means a lot
Worth the wait, pretty good video
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)
Thats actually is a really good idea
Very cool. I love seeing videos about rocket engines and KSP, and this is the best of both worlds. Great job!
Glad you enjoyed it!
LOVE IT.
Im thrilled!
Really well made video
@@108Pi thanks!
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! 👏
Thanks! Researching the engines did take some time, but it was really fun learning about all the engines and how they work, and making the schematics also helped me understand the engines more.
Good video, you explain it well
Glad you liked it!
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!
@Makemakeboy Thanks! My previous videos are a lot lower quality than this one which is why i had the low sub count, but i am very glad you like it!
Very informative and entertaining video, earned yourself a sub
Thank you very much!
Love the video man
Thanks!
this was extremely informative, I learned many new things. thank you.
@grendizergo4193 Thanks, glad you were able to understand it!
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.
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😄
Thats actually pretty interesting, I'll have another look later today. Thanks!
This is sick! Could you do one on all the srbs too?
Thanks, I'm thinking about doing a follow-up covering the remaining engines, like jet engines, monoprop and SRB's.
I feel like making a similar video for juno new origins, I can see the amount of editing you put into this, well done
Thanks! Thats actually a really good idea, even tho JNO has less engines. You could also try recreating KSP engines in JNO, could be interesting
You should do air breathing engines next
Might do that, plus all the remaining engines (monoprop, srb's)
You making me want to get back into ksp nice vid
Go for it
this was cool!
@@clippedwings225 Thanks!
Very well made and educational. Would like to see coverage of engines from KSP1 mods, like Tantares (more Soviet engines and parts), Tundra Exploration (SpaceX) and even Near Future/Far Future/Interstellar Extended (theoretically possible electric/fission/fusion/beam power/antimatter).
Thats definitely the idea! First i want to do the remaining stock engines (jets, srb, monoprop), and then start doing modded parts from for example Cryogenic Engines and Near Future
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!
@TotallyNoAim Ah that makes sense. Thanks for the correction
@@zenothksp ur welcome
You might want to check out Restock revamping of those engines for more precise depiction of the plumbing in KSP 1
Yeah i usually play with restock, but i wanted this video to be 100% stock, and some restock engines, are analogs for different IRL engines. I did use the restock model for the vector, because the stock vector has no plumbing at all.
cool video
@@francescobarone2094 Thanks
Yipee new video
Could you please also cover the KR-2L Rhino from the first game? I'm very curious how that thing works
That one is also inspired by the J-2X, but the model is less detailed so the TPA's and fuel lines for example aren't shown. But it pretty much works the same as the Rhino in KSP2
But in ksp making history the skiff is a different engine from the rhino. And clearly resembles the j2, however the rhino looks nothing like it and has absolutely ludicrous thrust and size in comparison...
@@jjthejetplane11 The Skiff resembles the J-2, the Rhino resembles the J-2X. Im not sure if the scales are correct
my man really said 🤓🤓🤓🤓🤓🤓🤓🤓🤓🤓
love it
i dont know existence of SABRE. Thank you.
@@slevinshafel9395 Yeah its a very interesting engine, one of my favorites
❤❤
Bro I was just watching ur RSS video from one year ago and jeez ur voice has changed
Hope its for the better
please tell me what music you're playing at 8:00? i've been trying to find it
We're finally landing
@@zenothksp thank you so much! I've been asking every time I've heard it played to other RUclipsrs and haven't heard anything. I really appreciate you taking the time to share this song with me
@@hfries1788 No problem! There's a browser extension called Shazam that can recognize songs playing in your browser, I recommend you use that if you ever want to know a song
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
@krolon9786 I get that. I thought maybe it was just a fun fact comparing them to F1 engines. Thanks for the tip
1:19
If exhaust gets in the oxygen tank, it wouldn't have fuel to burn, same goes for the fuel tank, it wont have any oxygen. Unless the tanks burst, it wouldnt explode.
Just saying!
If the combustion gasses went up, they could heat up the propellant inside the tank. This increases pressure massively, so the propellant either gets forced out the tank very fast, or it raptures
Please add captions
Did you try the automatically generated captions?
@@zenothksp they had a stroke
I have a problem: When I loaded the ksp 2 the flag of the campaign is gone. How am I supposed to fix it?
@fedormaslov508 that is a well known bug but i dont know how to fix it. My solution would be to uninstall Ksp2, and ask for a refund because it will not be updated again
@@zenothksp okay
Sorry, but it's Lr, not XLR
You're partially right, the LR engines were used on the Atlas E and F, whereas the XLR engines were used on the Atlas D. I just found the XLR engines before the LR engines which is why I included them in the video, but you are right.
@@zenothksp Oh, didn't know that, thanks👍 Great video btw
mislleading tilte no solid engines explained
In the intro i explain that i will only cover liquid fueled engines. Im planning on making a video covering all remaining engines, including jet engines, monoprop engines and srb's
Shouldn't the video be marked as KSP2 video instead of KSP?
@kalkovonschpritzendorf1914 I also used a lot of KSP1 engines and footage in this video, and since the layoffs KSP2 has plummeted in the algorithm, so I just used KSP in the title
@@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.
@kalkovonschpritzendorf1914 Same way for me. I believe if you live in the European Union you can refund the game, regardless of play time
the poodle is the transtage engine, drago was ranting about this and you addressed none of it
then bro ignores my comment
Didnt ignore it, just didnt see it. There are only like 2 decent images of the transstage engine, and tbh i also kinda forgot about it@WernherVonKerman.
ksp2* not ksp
Both games are featured in the video
