About
The Single-Actuation Drive, Type 5, 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 a satellite. The drive was released in 2010 and is estimated to have a production/delivery time of 12 months. It features a nominal slew rate of 2 degrees per second and a torque rating of 0-35 N·m, with a safety clutch actuation time between 35-40 N·m. The output shaft exhibits an antitorque moment not exceeding 0.2 N·m in a de-energized state. Designed for the harsh space environment, it operates within a temperature range of -60 to +60 °С and has an operational life of at least 100 cycles or 52 hours. Its compact dimensions are 85 x 93 x 80 mm, and it weighs 0.75 kg.
