Abstract
A thrust reverser actuation system includes a plurality of actuators, a power drive unit, and a gear set. Each actuator is coupled to receive an actuator input torque and is configured, upon receipt of the actuator input torque, to move between a stowed position and a deployed position. The power drive unit has only one output shaft, and is configured to supply a drive torque via the output shaft. The gear set is connected to the output shaft and is coupled to each of the actuators. The gear set is configured to receive the drive torque via the output shaft and to supply the actuator input torque to each of the actuators.

A thrust reverser actuation system, comprising:
- plurality of actuators, each actuator coupled to receive an actuator input torque and configured, upon receipt of the actuator input torque, to move between a stowed position and a deployed position;
- a power drive unit having only one output shaft, the power drive unit configured to supply a drive torque via the output shaft;
- and
- a gear set connected to the output shaft and coupled to each of the actuators, the gear set configured to receive the drive torque via the output shaft and supply the actuator input torque to each of the actuators.
A thrust reverser actuation system, comprising:
- a plurality of actuators, each actuator coupled to receive an actuator input torque and configured, upon receipt of the actuator input torque, to move between a stowed position and a deployed position;
- an electric motor having only one output shaft, the electric motor adapted to be selectively energized and configured, upon being energized, to supply a motor drive torque via the output shaft;
- and
- a right angle, speed-reducing gear set, the gear set having a gear set input shaft, a first gear set output shaft, and a second gear set output shaft, the gear set input shaft connected to the motor output shaft to receive the motor drive torque, the first gear set output shaft and the second gear set output shaft each coupled to at least two of the actuators to supply the actuator input torque thereto.
A thrust reverser actuation system, comprising:
- a first moveable thrust reverser component configured to move between a stowed position and a deployed position;
- a second moveable thrust reverser component configured to move between a stowed position and a deployed position;
- plurality of first actuators, each first actuator coupled the first moveable thrust reverser component, each first actuator further coupled to receive an actuator input torque and configured, upon receipt of the actuator input torque, to move between a stowed position and a deployed position, to thereby move the first moveable thrust reverser component between its stowed position and deployed position, respectively;
- plurality of second actuators, each second actuator coupled the second moveable thrust reverser component, each second actuator further coupled to receive an actuator input torque and configured, upon receipt of the actuator input torque, to move between a stowed position and a deployed position, to thereby move the second moveable thrust reverser component between its stowed position and deployed position, respectively;
- an electric motor having only one output shaft, the electric motor adapted to be selectively energized and configured, upon being energized, to supply a motor drive torque via the output shaft;
- and
- a gear set connected to the output shaft and coupled to each of the first actuators and to each of the second actuators, the gear set configured to receive the drive torque via the output shaft and supply the actuator input torque to the first actuators and the second actuators.
