Utility class that handles power transmission in conjunction with FGRotor.
This class provides brake, clutch and free-wheel-unit (FWU) functionality for the rotor model. Also it is responsible for the RPM calculations.
When the engine is off the brake could be used to slow/hold down a spinning rotor. The maximum brake power is defined in the rotors' config file. (Right now there is no checking if the input is in the [0..1] range.)
The clutch operation is based on a heuristic approach. In the intermediate state the transfer is proportional to the clutch position. But equal RPM values are enforced on the thruster and rotor sides when approaching the closed state.
The FWU inhibits that the rotor is driving the engine. To do so, the code just predicts the upcoming FWU state based on current torque conditions.
Some engines won't work properly when the clutch is open. To keep them controllable some load must be provided on the engine side (EngineFriction, aka gear-loss). See the notes under 'Engine issues' in FGRotor.
Property tree
The following properties are created (with x = your thruster number):
propulsion/engine[x]/brake-ctrl-norm
propulsion/engine[x]/free-wheel-transmission
propulsion/engine[x]/clutch-ctrl-norm
Notes
-
EngineFriction is assumed constant, so better orientate at low RPM values, because piston and turboprop engines don't 'like' high load at startup.
-
The model doesn't support backward operation.
-
And even worse, the torque calculations silently assume a minimal RPM value of approx. 1.
