Abstract
Systems and methods for hydraulic droop control of an aircraft wing. One embodiment is a hydraulic droop panel system for an aircraft wing. The hydraulic droop panel system includes a first hydraulic actuator attached to a flap of the aircraft wing, and a second hydraulic actuator attached to a droop panel of the aircraft wing and fluidly coupled with the first hydraulic actuator. The second hydraulic actuator is configured to move the droop panel to a droop position corresponding with movement of the flap and the first hydraulic actuator.
Claims20
A hydraulic droop panel system for an aircraft wing, the hydraulic droop panel system comprising:
- a first hydraulic actuator attached to a flap of the aircraft wing;
- and
- a second hydraulic actuator attached to a droop panel of the aircraft wing and fluidly coupled with the first hydraulic actuator, the second hydraulic actuator configured to move the droop panel to a droop position corresponding with movement of the flap and the first hydraulic actuator.
A method for controlling a droop position of an aircraft wing, the method comprising:
- mechanically coupling a first hydraulic actuator to a flap of the aircraft wing;
- mechanically coupling a second hydraulic actuator to a droop panel of the aircraft wing;
- fluidly coupling the second hydraulic actuator and the first hydraulic actuator with hydraulic fluid;
- and
- moving the flap to drive the first hydraulic actuator and force the hydraulic fluid from the first hydraulic actuator to the second hydraulic actuator, the force of the hydraulic fluid causing the second hydraulic actuator to move the droop panel to a droop position corresponding with movement of the flap and the first hydraulic actuator.
A wing of an aircraft, the wing comprising:
- a flap configured to move via a mechanical actuator;
- a spoiler;
- and
- a hydraulic linkage between the flap and the spoiler configured to translate movement of the flap into a rotation of the spoiler about a hinge.
