    摘要: An electric control system and method for operating the cowl doors of an aircraft engine that includes one embodiment with one or more electric motors that are energized to move the cowl doors to the open position. The motor is de-energized and the cowl doors are allowed to close under their own weight, driving the motor and causing it to operate as a generator. An electrical load absorbs the energy generated by the motor while the cowl doors close, thereby limiting the speed at which the doors close.

    摘要: A thrust reverser system includes one or more actuators each having a locking mechanism that prevents unintended actuator movement, and thus unintended thrust reverser movement. Each of the actuators additionally includes a lock inhibitor assembly that engages the lock and prevents it from moving to its locked position until the actuator is moved into a stow position. Upon movement to the stow position, the lock inhibitor assembly disengages the lock, and the lock automatically moves into its locked position.

    摘要: A thrust reverser system includes one or more actuators each having an integrated locking mechanism that prevents unintended actuator movement, and thus unintended thrust reverser movement. Each of the actuators with the integrated locking mechanism includes a housing, a drive shaft, and a lock. The drive shaft includes an outer surface, is rotationally mounted within the housing, and is operable, in response to the operation of the one or more motors, to rotate in a first rotational direction, to thereby move the thrust reverser to the deploy position, and a second rotational direction, to thereby move the thrust reverser to the stow position. The lock is movably mounted within the housing and is operable to move between at least a first position and a second position, and includes at least a side surface and a bottom surface. One or more gears are provided on the outer surface of the drive shaft, each of which is adapted to mesh with gears that are operably coupled to the thrust reverser. In addition, one or more protrusions extend from the outer surface of the drive shaft. Each of the protrusions includes a stop surface configured to fixedly abut the lock side surface when the lock is in the first position, and a tapered surface configured to slidingly abut the lock bottom surface when the lock is in the first position. Thus, rotation of the drive shaft in the first rotational direction is prevented and rotation of the drive shaft in the second rotational direction is allowed when the lock is in the first position.

    摘要: A thrust reverser system that has one or more moveable thrust reverser components for redirecting the thrust of a jet engine. The thrust reverser system has a torque limiter coupled between synchronization mechanisms that mechanically couple actuators used to drive the thrust reverser. The torque limiter reduces the potential for the transmission of excessive torque between thevdifferent moveable thrust reverser components, and reduces the likelihood of secondary system damage due to a jam in the system. Thus, the cost and/or weight associated with each of the components comprising the system may be reduced.

    摘要: A controllable motor includes a rotor. A first stator winding set is operable, upon being energized, to generate and apply a first torque to the rotor. A second stator winding set independent of the first stator winding set is operable, upon being energized, to generate and apply a second torque to the rotor. A motor control is coupled to the first and second stator winding sets. The motor control is operable to selectively energize one of the first or second stator winding sets to thereby generate and apply one of the first or second torques to the rotor, and simultaneously energize both the first and second stator winding sets to thereby generate and apply a third torque greater than the first or the second torque.

    摘要: An improved jet engine thrust reverser that includes a sensor to determined the rotational position of a motor. The system includes an actuator, a motor, motor position sensor, and an electronic control unit. The electronic control unit converts the rotational position of the motor to thrust reverser system using, for example, a summation algorithm and reset logic. The summation algorithm incrementally calculates absolute position of the thrust reverser from the sensed motor rotational position.
