About
The Single-actuation Drive, Type 3, is an electromechanical rotary drive specifically engineered for the deployment of critical spacecraft structure elements. Its primary purpose is to facilitate the controlled deployment of components like solar array panels, booms, and antennas, which are essential for the operational functionality of satellites. The drive was first released in 2012 and has a proven flight heritage, having been successfully deployed on the Express-AM5, Express-AM6, and Yamal-401 spacecraft. It operates with a nominal slew rate ranging from 1.2 to 2.8 degrees per second and has a torque rating of 25 N·m. A safety clutch is integrated, actuating between 50-75 N·m to prevent damage. The output shaft exhibits an antitorque moment not exceeding 3 N·m in a de-energized state. Designed for the harsh space environment, it can operate within a temperature range of -50 to +60 °С and boasts an operational life of at least 100 cycles or 50 hours. The compact design measures 70 x 94 x 92 mm and has a mass of 0.76 kg. The estimated production/delivery time is 6 months.
