Thrust reverser position determination system and method

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.
