A UAV rocket booster which can be separated automatically and safely is proposed to improve the separation safety of booster mechanism of rocket-propelled UAV during take-off.Taking a UAV as an example,a theoretical model of UAV booster with the goal of optimal separation safety is established by using theoretical mechanics and rigid body kinematics knowledge.The design basis of the key parameters in the booster is obtained,and a three-dimensional model of booster is established.The separation trajectory of the improved separation mechanism is obtained by using the rigid body dynamics analysis method.An experiment system including the booster and the simulated UAV part is established to verify that the separation trajectory and attitude of the booster have the same changing trend with the simulation structure.The results show that the booster can effectively avoid the hidden danger in the process of separation,and improves the safety of the booster mechanism separation.
