Abstract
Rotorcraft including a fuselage and at least three rotor system arms each having a rotor system. Each rotor system includes a mast having at least two rotor blades and an electric rotor motor. At least one rotor system arm includes a support mechanism for pivotally supporting a floating mast about at least one pivot axis whereby the floating mast is tillable relative to a fiducial tilt position. The floating mast has a controllable cyclic rotor blade pitch. A mast tilt measurement mechanism provides a mast tilt feedback signal regarding a measured tilt position of a floating mast relative to its fiducial tilt position. A flight control system continuously controls the at least three electric rotor motors and the floating masts cyclic rotor blade pitch in response to a desired input maneuver and its mast tilt feedback signal.
Claims12
A rotor system for use in a rotorcraft, the rotor system comprising:
- a) a mast having at least two rotor blades attached thereto for rotation by an electric rotor motor to act as a rotor disc,
- said rotor disc having a controllable cyclic rotor blade pitch;
- and
- b) a dual axis support mechanism for pivotally supporting said mast about dual pivot axes whereby said mast is a floating mast tiltable relative to a fiducial tilt position by said controllable cyclic rotor blade pitch.
