Abstract
A telescoping aerial refueling probe includes a second section and a ball screw. The first section is telescopically mounted to the second section. The ball screw is rotationally mounted along the longitudinal axis of the probe. A hydraulic motor rotates the ball screw to drive a ball screw nut and attached first section relative the second section. The hydraulic motor communicates with the hydraulic system and is operated in response to a control system. A backup motor such as an electric motor alternatively drives the ball screw upon failure of the hydraulic motor. As only the backup motor is required for redundancy, minimal additional weight is added to the probe and a relatively compact system is provided.
