Solar Array Drive Mechanism (SADM)
Type SADM-1-2-2-2B SADM is designed with lightweight method. And it is the lightest SADM which is developed and applied in the practical engineering by SAST.The mechanism has 4-level maturity. It is applied successfully in satellites, Lunar exploration and deep-space detection. The product design life can be over 5 years(LEO). It can be promoted and widely applied on driving solar array of spacecrafts.
