Is thrust linear across throttle for all engines?

35.8k Graingy  2 months ago

I've always worked on the assumption that 50% throttle is 50% thrust for jet engines. Propellers are presumably much more complicated with RPM and pitch and whatnot, though what about the OG propeller?
Is the effect on the... Blasto BFE150 (The fighter jet turbofan) above certain throttles only a visual effect? Or is the function of the engine actually impacted in any way?

    @crazyplaness or that’s just the consequence of reduced drag. Have you compared two identical designs?

    @Graingy I’m pretty sure that fuel consumption is non linear though so multi engine planes with 50% throttle might be more efficient than a twin jet with 100% throttle

    @crazyplaness That’s good to hear (I think?)

    @Graingy I tested it and it’s the same

    @crazyplaness Huh. Thanks.
    I’m mostly concerned about the afterburning turbofan, though.

    I did a test and it is. A engine at 50% throttle produces 50% of its max thrust

    @hpgbproductions ah
    Well, I’ll have to take your word for that. Thanks.

    @Graingy thrust is proportional to throttle, except for the spool up/down time, which also has linear thrust

    @hpgbproductions Jets are linear, or they're not? Or do you mean the visuals on the big engine?
    You mean the thrust multiplier?

    Yes, use the thrust output variable

    @TheMouse Hm.

    I thought I read at one point that it did, but I cannot find that comment at the moment.
