The design and analysis of picosatellite deployer with controllable release function

Picosatellite deployer is used for carrying and releasing picosatellites during the launching and in space respectively. For releasing several picosatellites placed in one deployer controllably, one design scheme based on memory alloy spring is presented to make arbitrary picosatellite have the same separation velocity with combination springs. The key components of deployer are optimized and its kinematics characteristics are obtained with the help of kinematics simulation and analysis. The deployer's sample is obtained and its key technical indexes are verified, all experiment results shows the rationality of the scheme and the correctness of the analysis.
