Outline
A sea-launching ship will have complex nonlinear motion response under the environmental loads and launch impact load, which has a vital effect on the safety of rocket launching process. Based on the three-dimensional potential flow theory, this paper focuses on the motion responses of a sea-launching ship under the action of wind, waves, and impact loads in different sea states. And the effects of the dynamic position system and the launch ignition time on the motion of the launch ship were investigated. The results show that the launch impact load has a great influence on the pitch motion of the ship, especially when the wind/wave direction is parallel to the ship direction. The existence of dynamic position system will increase the roll of the launch ship. And the launch ignition time can be selected at the moment when the pitch motion of the launch ship is about to reach the extreme point, so as to reduce the impact of the launch ship's motion on the rocket attitude during taking-off.
