Abstract: A brake position sensor unit includes a unitary brake shaft that transmits braking torque to a article to be slowed, connects directly to a brake unit, connects to a resolver and has a plurality of planetary gears rotating thereabout to activate a sensor when the brake unit is set.

Abstract: A propeller system includes a propeller hub 26 which supports a multiple of propeller blades 30. A tailshaft 26B extends from a propeller hub portion of the propeller hub along an axis of rotation with a propeller pitch change yoke 46 mounted within the propeller hub for movement along an axis of rotation to change a pitch of the multiple of propeller blades via pitch change linkage 44. This system does away with the necessity for the usual separate piston/cylinder actuator.

Abstract: A method of controlling an aircraft 80 comprising at least one propeller system 20 having a plurality of rigidly mounted propeller blades 32, the pitch of the blades 32 being collectively adjustable to generate a thrust, and cyclically adjustable to generate a moment. The combination of the thrust and moment may be used to generate a bending moment about an axis, or axes, X, Y, Z of the aircraft 80. The method may use two propeller systems 20 on an aircraft 80 to generate a trust, moment and/or bending moment(s). Details of the cyclic and collective blade pitch adjustment mechanisms are also disclosed.
