1. A rotor aircraft, comprising:

  • an engine having an output shaft;

    at least one forward thrust device driven by the engine to provide forward thrust to the aircraft;

    wings for providing lift while in forward flight;

    a rotor having a rotor drive shaft and mounted for selectively providing lift; and

    rotor drive means for selectively providing torque to the rotor drive shaft from the output shaft of the engine at a speed proportional to a speed of the output shaft of the engine while in a first mode and for selectively providing torque to the rotor drive shaft to rotate at a speed independent of a speed of the output shaft of the engine while in a second mode.
