Abstract
A system for an aircraft includes a tiltable proprotor that is tiltable between a lift position for providing lift for the aircraft and a forward flight position for providing forward propulsion for the aircraft is provided. The system includes at least one actuator for adjusting a tilt angle of the tiltable proprotor; and at least one passive damper connected to the tiltable proprotor and configured to limit a rate of change of the tilt angle of the tiltable proprotor.
Claims36
An aircraft comprising:
- a tiltable proprotor that is tiltable between a lift position for providing lift for the aircraft and a forward flight position for providing forward propulsion for the aircraft;
- at least one actuator for adjusting a tilt angle of the tiltable proprotor;
- and
- at least one passive damper connected to the tiltable proprotor and configured to limit a rate of change of the tilt angle of the tiltable proprotor,
- wherein the at least one passive damper is configured to limit the rate of change of the tilt angle of the tiltable proprotor in both tilt directions, and
- wherein the at least one passive damper is on a load path separate from a load path of the at least one actuator.
3 more elements
A method for controlling an aircraft, the method comprising:
- receiving a command at a controller to adjust a tilt angle of a tiltable proprotor that is tiltable between a lift position for providing lift for the aircraft and a forward flight position for providing forward propulsion for the aircraft;
- and
- controlling at least one actuator to adjust the tilt angle of the tiltable proprotor according to the command, wherein at least one passive damper is connected to the tiltable proprotor to limit a rate of change of the tilt angle of the tiltable proprotor,
- wherein the at least one passive damper is configured to limit the rate of change of the tilt angle of the tiltable proprotor in both tilt directions, and
- wherein the at least one passive damper is on a load path separate from a load path of the at least one actuator.
