Abstract:

In this paper, the basic characteristics and requirements of the submarine launched air defense missile unpropelled capsule was briefly analyzed. A mathematic model of capsules moving under water were established by quaternion and vector matrix, and the simulation model of submarine unpropelled capsule based on Simulink was established. Then the underwater trajectory of the unpropelled capsule was discussed. It had certain guiding significance for design of the capsule. The simulation showed that the launching velocity of the vehicle has influence on the deviation of navigation, the navigation time was related to the launching depth.
