Abstract: A powered clutch actuator assembly for integration with a clutch assembly is provided. The actuator and clutch assemblies, sized to fit within constraints of an aircraft landing gear wheel-mounted taxi drive system, are engineered to occupy a default neutral disengaged position that prevents torque transfer when torque to move the aircraft should not be transferred to the taxi drive system. Multiple solenoids and diodes power rotational motion of the actuator assembly to move a bi-directional clutch component in a desired rotational direction during torque transfer. A locking solenoid automatically locks and maintains the actuator assembly in a neutral disengaged condition when none of the solenoids are powered and disengages the actuator assembly when one solenoid is powered to cause rotation of the actuator assembly. Solenoid supports structured to operate as integral heat sinks may direct heat to an on-aircraft heat sink, prolonging the working life of the actuator assembly.
