Dynamic Analysis on Ballistic Characteristic of Suspended Projectile's Falling and Floating Process

To investigate ballistic characteristics of the suspended projectile's falling and floating during thrown from carrier shell to stable suspension, the suspended projectile's rigid body trajectory model which based on dynamic analysis of the falling process of the rotor was build. Then calculation was conducted by quaternion other than Euler angle. According to the principle that with certain driving energy, make the suspended projectile decelerate and despin faster, and be in suspension stage for longer time, the best driving mode and the size of the driving torque can be got by changing relative parameter. The research lays a foundation for the following design and control strategy of the suspended projectile' s floating mechanism.
