Research on Launch Dynamics Modeling and Simulating for Surface-to-air Missile Supported by Adapter

The launch dynamics analysis model of surface-to-air missile supported by the adapter was established, and the model was verified by test data. Simulation analysis shows: the missile begins to generate pitch angular speed at semi-constrained state after mid-adapter leave the tube, and the speed increases with distance between the mid-adapter and the rear adapter, and as the thrust of the engine increases to decreases, as the launch angle decreases, the missile's pitch angular speed increases, gravity is the main cause of the launch disturbance in the direction of the pitching.
