About
The Single-actuation Drive Type 1 is an electromechanical rotary drive specifically engineered for the deployment of large mechanical system elements on spacecraft. Its primary purpose is to facilitate the unfolding and positioning of critical components like solar array panels, booms, and antennas. The drive was released in 2009 and has a proven flight heritage, having been deployed on several satellites including Amos-5, Telkom-3, KazSat-3, Express-АТ1, Express-АТ2, and Express-АМ8. It operates with a nominal slew rate of 2-4 degrees per second and has a torque rating of 25 N·m. A safety clutch actuates between 50-75 N·m, and the output shaft maintains an antitorque moment not exceeding 2 N·m in a de-energized state. The drive is designed to operate within a wide temperature range of -50 to +60 °С and has an operational life of at least 100 cycles or 48 hours. Its compact dimensions are 70 x 94 x 92 mm, and it weighs 0.75 kg. The estimated production and delivery time for this product is 6 months.
