Glad you could clear up some of my misconceptions, thanks 1) Interesting! I just assumed (shouldn't assume so much I guess ) that since I've seen videos of f-14 and such do it, that most other jets can do it as well. Anyone have a .craft which can do this btw? 2) I don't really mind a high SFC, I don't have enough patience to fly very long anyway! Wow did not know! If you have proper sources I suggest you write something on the wiki page, read it all but it didn't say anything about that! (Not doubting you, did read about it on some other webpage) So is there a .craft for a mach 3+ aswell, or perhaps just some pointers in constructing one? Ah so the ksp engines do behave like I thought they should Must fly some more and learn to fly them better I suppose! You guys talked about SFC and efficiency, aiding understanding of those things in flight would be a fuel rate meter or some other measurement of fuel consumption. Good reasons on the heat issue! The fuel meter would be a better incentive to not just floor it all the time. The plans on the different engine parts sounds excellent, really brings a lot of customization enabling planes of wider range of sizes! Making a long and extra powerful engine is great, I don't really like to have too many engines.

I see! However my opinion is still that they are too weak. For example, many fighter jets easily break the sound barrier at sea level, while I cant get more than mach 0.5 with the FAR Slothful Hummingbird. Also to note, 150kN thrust is very similar to the engine in sr-71 blackbird, so the value itself isn't unrealistic. Regardless of actual values, two engines and a lightweight airframe should do mach 3.2 like the blackbird, in my opinion A question, does ksp simulate the exhaust velocity of the jet engines? Because a "basic" engine could have more static thrust, but too low exhaust velocity to go much above mach 1, compared to a ramjet style engine that has less static thrust but keeps going past mach 3. Actually to me, 3 types of engines are needed: Turbofan (airliner engine), for heavy planes that are subsonic. High static thrust but low exhaust speed. "normal" jet engine perhaps with afterburner, for lighter "fighter jet" style planes. Lower thrust but higher exhaust speed. Still viable in a wide range of operation from sea level to "pretty high" (unsure if the ksp atmospheric model is comparable to the earths, but like 16 000 m.) Then the ramjet, which plain sucks a low altitudes and speeds, but has a very high exhaust velocity enabling speeds above mach 3. Soo... One more suggestion Was flying along trying to push the mach numbers ever higher, and realized all I did was trying to find the best altitude with full throttle all the time. Found that it was very sensitive and I didn't think it was all that fun. So my suggestion here to make things more interesting is adding overheating as a element. Basically trying to take of at 100% will blow your plane up, so you have to dial it back a bit and beware of the temperature and wait for some more speed for cooling. Only when in the correct altitude/speed range can you really floor it! But then if you are going too fast (over 3.5 or something) you start to heat up again, so that the speed limit isn't really how much thrust you have but your cooling capacity. In my mind, this will make pushing ever greater speeds more exiting because if you're not on top of it, the plane will blow to bits. Of course this is mostly only relevant to the ramjet category and perhaps a bit for the "normal" engines. The turbofans should be easy to fly. Anyway just my 2 cents, and I'm no jet engine expert anyhow so I might just be plain wrong Thanks!

Thanks for the mod, much needed! Just having some troubles, overall it seems that the engines are underpowered. But it might have just been me, so I tried a couple of the example aircraft. Some of them had wrong cg/col positioning and the control surfaces was not setup. Fixed those problems and tried flying them, but I could only fly the FAR Slothful Hummingbird and the FAR Javelin Racer II, with any success (didn't try all of them though). Got them up to 2.6 and 1.03 mach respectively. The others just didn't fly well or stalled way to easily, as in the case of the su-35 which just felt like it didn't have enough power and stalled when trying to take a turn. So is it just me or is this just like it's designed to be like?
