Hose Drum Drive System (HDDS)
The Hose Drum Drive System controls the curling and the coasting of an air tanker during flight refueling. WITTENSTEIN supplies the actuator system which includes a dual redundant motor, a gearbox, and sensors for monitoring winding temperature and motor shaft position. A key feature of the actuator is a miniaturized electronic ID plate for recording the specific parameters of the individual actuator which will be measured during the final acceptance test. These data can be uploaded by the system control electronics allowing a more tailored control of system behavior, including ease of maintenance.
