Classification: CPC G  B  H | IPC B  G  H

Claim 14:
15. An aircraft, comprising:
a fuselage;
a propulsion engine coupled to the fuselage and configured to generate thrust to propel the aircraft along a first vector during forward flight; and
coaxial pairs of rotors coupled to opposite sides of the fuselage and configured to provide lift to the aircraft along a second vector during forward flight when the coaxial pairs of rotors operate in autorotation, each rotor comprising blades that rotate about a rotor axis, each rotor coupled to a motor, each rotor inclined at an angle with respect to a horizontal plane extending through the rotor axis during forward flight, and each motor configured to supply power to and draw power from the coupled rotor,
wherein an inclination of each angle above or below the horizontal plane is based on a position of each rotor relative to a center of the aircraft and a rotational direction of each rotor about each rotor axis,
wherein a first rotor in each coaxial pair is inclined at an angle measured above the horizontal plane, a second rotor in each coaxial pair is inclined at an angle equal and opposite to the angle of the first rotor, and the angles are mirrored on opposite sides of the fuselage for corresponding coaxial pairs, and
wherein power being supplied to or drawn from each rotor by its corresponding motor adjusts a rotational frequency of the rotor to provide attitude control for the aircraft.
