Abstract: An electromechanical portion of the control stick includes a two-axis gimbal, with each axis including a mechanical gimbal structure supported by rolling element bearings, cam based centering mechanisms, linkages to connect a geared power-drive including a resolver commutated brushless DC motor and compound-planetary gearhead to provide active force feedback, and several electrically independent RVDT position sensors. The gearing architecture uses a fixed-cage, rotating internal gear arrangement on a planetary gearhead, which may be single or multi-stage. The output torque of the gearhead is provided by a feature on the outer housing of the rotating internal ring gear, allowing an axial placement of the entire power-drive in a more central location, reducing the moment load on the gearhead output cage bearings, and facilitating a compact drive arrangement of the gimbal using linkages. Additionally, a common power-drive can be used for both the roll and pitch axes.

Abstract: Referring to FIG. 2, disclosed is an aircraft compound no-back/offset gearbox (2) with an integral load proportional safety (no-back) brake (50). The four gears are all 16 diametral pitch, involute external spur gears with 20 degree standard pressure angles.

The shearout (40) is essentially a quill shaft with external splines at both ends and an hourglass-shaped shear neckdown in the middle. The purpose of the no-back brake (50) is to prevent air loads from causing slat movement in the event of a torque tube disconnect. Referring to Figure, the no-back consists of a set of ball ramp (22) and brake plate components connected to the gearbox's output shaft.
