| 20090108129 | JAM TOLERANT ELECTROMECHANICAL ACTUATION SYSTEMS AND METHODS OF OPERATION - In a vehicle, having a fixed supporting structure and a load movable relative thereto, a jam tolerant actuating system, a method for controlling this system including: Locating a physical coupling/decoupling mechanism between the load and an actuator assembly as close a practicable to the load; constructing the coupling/uncoupling mechanism to be reversible, and hence testable; and controlling the connection/disconnection via decision making electronics which will detect any system failure by monitoring, at a minimum: actuator main motor load and speed, and actuator output load. Also set forth are specific embodiments of pivotable rotary geared actuators as well as linear ball screw type actuators embodying the coupling/uncoupling mechanisms of this invention. | 04-30-2009 |

| 20090314884 | JAM-TOLLERANT ACTUATOR - An actuator, comprises a housing, a first prime mover for producing rotary motion, a first gearbox arranged to convert in use the rotary motion from the first prime mover into rotary motion having higher torque and lower speed. The first gearbox comprises a casing mounted for rotation relative to the housing of the actuator and a second gearbox arranged to convert rotary motion of the casing of the first gearbox into rotary motion having lower torque and higher speed. | 12-24-2009 |
| 20110127375 | Method for monitoring a no-back device of an adjustable horizontal trim actuator, corresponding system and aircraft - The present invention relates to a method and a system for monitoring of an actuator equipped with a no-back device or no-back brake and in particular an adjustable horizontal trim actuator provided in aircraft. | 06-02-2011 |
| 20130026287 | Method And Device For Detecting An Uncontrolled Movement Of An Aircraft Control Surface - Method and device for detecting an uncontrolled movement of an aircraft control surface. | 01-31-2013 |
| 20130327887 | DEVICE FOR AN ADJUSTABLE FLAP OF A WING - The invention concerns a device for a adjustable flap adjustably mounted on a main wing surface of an aeroplane wing, in particular, a landing flap, with at least one adjustment unit for purposes of adjustment of the adjustable flap, which has an actuator arranged, or that can be arranged, on the main wing surface, and has a kinematic adjustment mechanism running between the actuator and the adjustable flap, wherein the adjustable flap is mechanically coupled with the actuator via the kinematic adjustment mechanism. At least one damping unit for purposes of damping a dynamic loading effected by the adjustable flap on the adjustment unit, which can occur as a result of a critical malfunction event occurring in the region of the adjustable flap, is arranged, or can be arranged, between the main wing surface and the adjustable flap. | 12-12-2013 |
| 20140138482 | Asymmetry Brake With Torque Limit - An electric fail-safe is operable to move a first ramp between distinct positions. The first ramp is associated with the second ramp. There are balls intermediate the first and second ramps. When the electric fail-safe brake is in an actuated condition, the second ramp forces stationary brake disks to engage rotating brake disks which rotate with a shaft to cause braking of the shaft. There is a keeper associated with the second ramp which abuts a stop surface to limit the amount of torque applied to the rotary and stationary disks after a predetermined amount of braking force has occurred. A brake with a test switch is also disclosed. | 05-22-2014 |
| 20140263829 | APPARATUS FOR USE ON AN AIRCRAFT - An actuator is arranged to move an aircraft component such as a landing gear leg, flap or aileron between a first position and a second position, net load from external forces acting on the aircraft component tending to drive it towards the first position. The actuator comprises a threaded screw and a threaded nut. A main prime mover is configured to apply torque to the screw or nut acting in opposition to the net load under normal operating conditions. An emergency prime mover is configured to apply torque to the screw or nut acting in the same sense as the net load under emergency operating conditions in which the interface between the nut and the screw has become partially jammed to the extent that the component cannot be moved from the second position to the first position by operation of the net load alone. | 09-18-2014 |
