Title:
NO-BACK BRAKE FOR FLIGHT CONTROL ACTUATION SYSTEM AND METHOD
Document Type and Number:
Japanese Patent JP2023155892
Kind Code:
A
Abstract:
To provide a no-back brake that does not easily wear out.SOLUTION: A no-back brake includes a torque tube and a brake. The brake is configured to be axially displaced in response to a force to prevent the torque tube from rotating. The brake includes a rotor that is concentric with the torque tube and that is fixed to the torque tube so that the rotor rotates with the torque tube. The brake includes a stator that is concentrically mounted on the torque tube such that the torque tube is rotatable relative to the stator. The brake includes a friction device located between the rotor and the stator. The friction device is configured to form a frictional coupling between the rotor and the stator that opposes relative rotational motion between the rotor and the stator when the brake is axially displaced. The frictional device includes a composite material.SELECTED DRAWING: Figure 4
