An aircraft is equipped with hingeless rotors on tilting nacelles, and the tilt angles of the nacelles are controlled using either or both of an actuator and a mast moment generated by a hingeless rotor. An aircraft with two or more rotors on tilting nacelles can achieve control of yaw orientation by differential tilt of its nacelles or masts. Hingeless rotors can be manipulated to control a tilt angle of a mast by changing the rotor blade pitch to produce a mast moment. The rotor and nacelle tilt of a tiltrotor rotorcraft can be controlled and effected ...
What is claimed is: 1. A method of controlling an aircraft having first and second hingeless rotors on first and second tilting masts, respectively, the first and second masts having first and second tilt actuators, respectively, comprising:providing a 4 bar linkage wherein said tilt actuators are rotary actuators that cooperate to assist in tilting the first mast, and wherein said 4 bar linkage comprises a first link, a second link, a tilting nacelle and an inner wing;changing rotor blade pitch on the first rotor to produce a first mast moment that cont...
