20220355915, Nov 10, 2022

Filed:

May 5, 2022

Appl. No.:

17/737729

Inventors:

- Dublin, IE
Daniel Henry Roberts - Monrovia CA, US

International Classification:

B64C 13/28
B64C 13/34

Abstract:

Various flight control components can be operated through gearbox driven rotary actuators. In the event of a jam occurring the gearbox, the gearbox can be decoupled from a surrounding support housing to enable free-trailing or limited motion relative to the support housing. The motion may or may not be damped. Decoupling the gearbox enables the flight control component to move to a neutral or non-interfering position even when user control over the component has been lost.

Daniel Henry ROBERTS - Monrovia CA, US

Assignee:

EATON CORPORATION - Cleveland OH

International Classification:

F15B 15/26

US Classification:

91 41

Abstract:

An actuator includes a cylinder and a piston disposed in the cylinder. The piston has a head and a rod. The actuator further includes a collapsible locking member disposed in the head of the piston, and a gas-filled capsule disposed in the cylinder. The gas-filled capsule is in an expanded position when fluid in the cylinder is below a threshold pressure, and the gas-filled capsule is in a collapsed position when fluid in the cylinder is above the threshold pressure. The actuator also includes a lock piston operably connected to the gas-filled capsule. The lock piston engages the collapsible locking member and biases the collapsible locking member radially outward to a locked position when the gas-filled capsule is in the expanded position.
