A jam free dual redundant actuator lane changer system includes a primary lane system and a secondary lane system. The primary lane system is configured to provide actuation of a component during a normal operation while the secondary lane system remains in a standby configuration; and the secondary lane system is configured to provide an actuation of the component when the primary lane system fails or jams, but freed from its output to the component.

Jam free dual-redundant actuator lane changer system and process

A jam free linear actuator system includes a linear electro-mechanical actuator configured to actuate a component; a disengagement mechanism configured to disengage components of the linear electro-mechanical actuator in an event of a jammed failure; a fixed end fitting mechanical connection; and a trim end fitting mechanical connection. The fixed end fitting mechanical connection connects the linear electro-mechanical actuator to a portion of a system implementing the linear electro-mechanical actuator; and the trim end fitting mechanical connection connects the linear electro-mechanical actuator to the component.

Actuators can include a line replaceable brake unit including a window for inspecting brake elements. In particular, an actuator system includes a modular brake component having an integral brake housing configured to mount to a motor, wherein the integral brake housing is environmentally sealed; a drive coupling within the integral brake housing configured to mechanically couple with an output shaft of the motor; one or more braking disks arranged in the integral brake housing configured to brake movement of the drive coupling when engaged; an armature in the integral brake housing configured to engage or disengage the one or more braking disks with the drive coupling; and an inspection window through the integral brake housing aligned with at least a portion of the one or more braking disks. A method for implementing an actuator system is disclosed as well.

Systems provide and methods utilize a multi-bar linkage in conjunction with an actuator to provide mechanical advantage which increases as a control surface moves towards the extremes of its operating envelope.

Multi-bar linkage mechanism

An actuator having a first actuating channel, having a first motor, and a second actuating channel having a second motor where the output of the first actuating channel and the output of the second actuating channel are synchronized and methods of mechanically synchronizing two outputs of a two channel actuator.

Mechanically synchronized actuator and methods for synchronizing

A transmission with a load brake has a ball spline and a stabilizer ring for reducing chatter, a seal for preventing leakage, and an adjustment mechanism for extending the effective life of the brake disk stack. In the past, transmissions equipped with Weston brakes have experienced significant problems with instability and chatter. The present invention overcomes the problems of instability and chatter by introducing a ball spline at the junction between the output shaft and the loading assembly. The ball spline reduces friction caused by the axial movement of the output cam of the loading assembly. Also, the invention introduces a stabilizer ring around the loading assembly to reduce instability and chatter caused by the angular and transverse movement of the loading assembly. The invention also may also utilize a fluid damper in place of the stabilizer ring to reduce instability and chatter caused by the angular and transverse movement of the loading assembly. The invention substantially reduces leakage of transmission fluid by placing a seal including two sealing members around the opening in the casing of the transmission through which the output shaft passes. A layer of relatively high-viscosity grease is introduced between the two sealing members to provide a dam against leakage of transmission fluid. An adjustment mechanism may be used to reconfigure the brake disk stack to its original settings after a pre-determined number of cycles of use of the transmission.
