About
The Single-actuation Drive Type 4 is an electromechanical rotary drive developed in 2005, specifically engineered for the deployment of large mechanical system elements on spacecraft. Its primary purpose is to facilitate the controlled deployment of critical components like solar array panels, booms, and antennas. The drive features a nominal slew rate ranging from 0.3 to 0.7 degrees per second and a torque rating of 60 N·m. It incorporates a safety clutch that actuates between 100-140 N·m to prevent damage. Designed for the harsh space environment, it operates within a temperature range of -50 to +70 °С. The operational life is specified as not less than 100 cycles or 51 hours. The compact unit measures 60 x 60 x 145 mm and has a mass of 0.7 kg. This drive has a flight heritage, having been qualified and flown on the Loutch-5A, Loutch-5B, and Loutch-5V satellites.
