Abstract
A rotorcraft including a fuselage and two diagonally opposite counter-rotating pairs of rotor systems mounted on the fuselage wherein each rotor system has a mast configured to have at least two rotor blades attached thereto and an electric motor coupled to the mast for driving the mast whereupon the at least two rotor blades act as a rotating rotor disc. Each rotor system of the two diagonally opposite counter-rotating pairs of rotor systems having an individually controllable collective rotor blade pitch and an individually controllable cyclic rotor blade pitch.

1-20. (canceled)
A rotorcraft comprising:
- a) a fuselage;
- and
- b) two diagonally opposite counter-rotating pairs of rotor systems mounted on said fuselage,
- wherein each said rotor system includes:
- i) a mast configured to have at least two rotor blades attached thereto, and
- ii) an electric motor coupled to said mast for driving said mast whereupon said at least two rotor blades act as a rotating rotor disc,
- each rotor system of said two diagonally opposite counter-rotating pairs of rotor systems having an individually controllable collective rotor blade pitch, and
- each rotor system of said two diagonally opposite counter-rotating pairs of rotor systems having an individually controllable cyclic rotor blade pitch.
The rotorcraft according to claim 1 wherein each rotor system of said two diagonally opposite counter-rotating pairs of rotor systems has an individually controllable cyclic rotor blade pitch.
The rotorcraft according to claim 1 and further comprising a flight control system for controlling said two diagonally opposite counter-rotating pairs of rotor systems.
A flight control system configured to control two diagonally opposite counter-rotating pairs of rotor systems in a rotorcraft according to claim 1, in response to an input control indicating a desired maneuver to operate the rotorcraft for takeoff, hovering, forward flight and landing.
A flight control system configured to control the two diagonally opposite counter-rotating pairs of rotor systems in a rotorcraft according to claim 2, in response to an input control indicating a desired maneuver to operate the rotorcraft for takeoff, hovering forward flight and landing.
A computer readable storage medium comprising instructions which, when executed by a flight control system in a rotorcraft according to claim 1, cause the flight control system to control the two diagonally opposite counter-rotating pairs of rotor systems in response to an input control indicating a desired maneuver to operate the rotorcraft for takeoff, hovering, forward flight and landing.
A computer readable storage medium comprising instructions which, when executed by a flight control system in a rotorcraft according to claim 1, cause the flight control system to control the two diagonally opposite counter-rotating pairs of rotor systems in response to an input control indicating a desired maneuver to operate the rotorcraft for takeoff, hovering, forward flight and landing.
A method for operating a rotorcraft comprising the steps of:
- a) providing a rotorcraft having:
- a fuselage,
- two diagonally opposite counter-rotating pairs of rotor systems mounted on the fuselage,
- each rotor system including:
- a mast configured to have at least two rotor blades attached thereto, and
- an electric rotor motor coupled to the mast for driving the mast whereupon the at least two rotor blades act as a rotating rotor disc,
- each rotor system of the two diagonally opposite counter-rotating pairs of rotor systems having an individually controllable collective rotor blade pitch,
- each rotor system of two diagonally opposite counter-rotating pairs of rotor systems having a controllable cyclic rotor blade pitch;
- and
- b) controlling the two diagonally opposite counter-rotating pairs of rotor systems in response to an input control indicating a desired maneuver to operate the rotorcraft for takeoff, hovering forward flight and landing.
