Realistic and simple helicopter engine.
Phunlet-safe, could be coped via clipboard (red box with thrusters).
No credits needed;) , you can use it as you wish.

In-game controls via 2 variables (of red box):
_power (0..1)
_pitch (radians)

Simulation:
Power falloff with altitude
Power falloff/increase with vertical (normal) speed
Power increase near ground

Design-time customization:
_maxThrust (newtons)

A lot of additional adjustments:
_flowSpeed - air speed throu blades in m/s (0 power on that speed)
_angleStab [0..1] - angle change sensetivity
_angvelStab [0..1] - angular velocity compensation sensetivity
_halfPowerAltitude - power falloff 1/2 on that altitude
_groundEffect [0..1] power increase near ground multiplier

p.s. add air friction to craft body for more realism

not working
Doesn't work with my algodoo:(
Not to worry I trust it works great, I'll look into disassembling the code and might try and make my own version:)

If you're up for a challenge [maybe?] and have the free time could you try and make another one that works similar to VTOL. I think that would be awesome!
You must download 2.0.2 from forum page, guys... sorry for that.
Oh, I've update it for 2.0.1 compatibility, just try again. :tup:
Fantastic thing!
Nice one Kilinich. You should add one more rotating blade phenomena applicable to helicopters. Dissymmetry of lift. When an helo gets to high speed, you have dissymmetry of lift because blade relative wind velocity gets higher on one side than on the other side of the helicopter. This cause the helicopter to nose up naturaly at high speed (because of gyroscopic precession). This is in fact the phenomena behind an helicopter speed limit. So its not because of power limit most of the time but because the nose goes up and therefore less forward lift.
2Antotabo: Yes, you right, I need to re-build it.
add a sharp nose cone to the heli so it has more aerodyamic effects
