Abstract
A tiltrotor has a range of motion between a forward flight position and a hovering position, where a pylon and the tiltrotor are coupled via a telescoping actuator, a rigid bottom bar, and a fixed hinge that is attached between the rigid bottom bar and the tiltrotor. The tiltrotor moves from the forward flight position to the hovering position includes extending the telescoping actuator so that the tilt rotor rotates about the fixed hinge.
Claims18
A system, comprising:
- a pylon;
- and
- a tiltrotor that has a range of motion between a forward flight position and a hovering position, wherein:
- the pylon and the tiltrotor are coupled via a telescoping actuator, a rigid bottom bar, and a fixed hinge that is attached between the rigid bottom bar and the tiltrotor;
- moving the tiltrotor from the forward flight position to the hovering position includes extending the telescoping actuator so that the tilt rotor rotates about the fixed hinge;
- the tiltrotor includes one or more propeller blades;
- and
- there is a lateral distance in a range of 0.5-1 ft., inclusive, between a plane associated with the one or more propeller blades when the tiltrotor is in the forward flight position and an axis of rotation of the propeller blades when the tiltrotor is in the hovering position.
