Abstract
There is provided an hydraulic actuation system for an aircraft, the hydraulic actuation system includes an actuator (A), a primary actuation arrangement to provide hydraulic fluid to control the actuator (A), wherein the hydraulic actuation system is configured to detect a fault in the actuator (A). The hydraulic actuation system also includes a secondary actuation arrangement to provide hydraulic fluid to control the actuator (A) in response to a detection of a fault in the actuator (A).
Claims13
A hydraulic actuation system for an aircraft, the hydraulic actuation system comprising:
- an actuator (A);
- a primary actuation arrangement to provide hydraulic fluid to control the actuator (A), wherein the hydraulic actuation system is configured to detect a fault in the actuator (A);
- and
- a secondary actuation arrangement, wherein, in operation, the hydraulic actuation system is configured to switch operation from the primary actuation arrangement to the secondary actuation arrangement to provide hydraulic fluid to control the actuator (A) in response to a detection of a fault in the actuator (A);
- wherein the primary actuation arrangement is provided on a static part of a nacelle and the secondary actuation arrangement is provided on a rotating part of a nacelle.

A method comprising:
- providing an actuator (A);
- providing hydraulic fluid to control the actuator (A) with a primary actuation arrangement;
- detecting a fault in the actuator (A) by an hydraulic actuation system;
- and
- switching operation from the primary actuation arrangement to a second actuation arrangement to provide hydraulic fluid to the actuator (A) with the secondary actuation arrangement in response to the detected fault in the actuator (A);
- wherein the primary actuation arrangement is provided on a static part of a nacelle and the secondary actuation arrangement is provided on a rotating part of a nacelle.
