Rocket Engines

31.2k IStoleYourMeme  2.7 years ago
Auto Credit Based on IStoleYourMeme's JATO Booster

Rocket engines made from every missile in the game. All of them have no drag and are strong enough to power most airplanes by themselves, you can use them as a rocket-assisted take off booster or as a standalone engine.
Save them as a sub-assembly and put them on your plane!

By default, AG 1 activates the rocket and AG 2 activates the detacher. To change the AG for the rocket, there is a pylon hidden in each of the engines.

Inferno Engine
30 second duration
1006 mph top speed

Guardian Engine
30 second duration
2683 mph top speed

Interceptor Engine
40 second duration
2073 mph top speed*

Cleaver Engine:
6 minutes 40 second duration
447 mph top speed

Additional info:
All engines were tested by launching the booster and a massless, dragless cockpit straight up into the air. All flew perfectly straight up except for the Interceptor which required stabilization by wings. Was not able to find the cause but it should be unnoticeable on a normal plane.

All missiles will slide out the back of the engine when they die out or if your plane goes past the missile's top speed.

Cleaver has wings that protrude from its sides on ignition.

At the end of the Cleaver's duration, the exhaust will go out but the sound of the engine will still be heard (probably a bug).

I tried to make an engine for the normal unguided Rocket but it explodes regardless.

*The Interceptor burns out before it stops accelerating so the top speed is only the highest recorded.

Some planes of mine that use these:
Me 262 C-1a
MXY-7 Ohka

    Properties which aren’t listed in the normal XML file but can be added manually or with Overload, like maxFuelTime or maxForwardThrustForce. You can see them all here. They weren’t added recently, I just found out about them pretty late. The engines still work, the properties just kind of make this a pointless upload, since you can just XML edit a missile to do whatever you want without needing to worry about what kind it is. @SnoWFLakE0s

    @IStoleYourMeme Which? Although, in recent testing of a similar concept on my own, yeah, they don't work. Although, there hasn't been a patch or whatever within the last 15 days to make this obsolete..?

    Just learned that there are hidden XML properties that make most of these obsolete. Sheeit
