Abstract: A system for moving an aircraft thrust reverser component includes a power drive unit, a thrust reverser actuator assembly, and a tertiary lock system. The power drive unit is operable to rotate and supply a rotational drive force. The thrust reverser actuator assembly receives the rotational drive force from the power drive unit and moves the thrust reverser component between a stowed position and a deployed position. The tertiary lock system selectively engages and disengages the thrust reverser component and includes a tertiary lock power unit, an electromechanical tertiary lock assembly, and a voltage limiting circuit. The voltage limiting circuit limits the voltage magnitude of a control signal supplied to the tertiary lock assembly to a predetermined value.

Abstract: Loudspeaker ROTOSUB including a motor driven rotor provided with wings or blades that are adjustable to their pitch and where the pitch is modulated by a signal, in particular electric, corresponding to a desired sound. In particular at very low frequencies the loud speaker rotor that during each sound wave length has time to rotate many revolutions can move large amounts of air that in turn can provide a large air and sound pressure. The technic is based on the generation of sound waves by modulating the angles of the wings. At low frequencies the rotor has time to rotate several revolutions per signal cycle which provides increased pressure. Since the wings can be pivoted in arbitrary angles the pressure can be controlled in the desired way.
