Abstract

In order to meet the requirements for reducing flight speed in the subsequent process of some long-rang rocker subcarrier ammunition,a study is conducted on the scheme of using body to achieve deceleration.A typical structure for implementing body deceleration scheme is selected in the articl, and the main aerodynamic parameters were calculated,and the aerodynamic characteristics were analyzed. Ballistic model is established using quaternion method,and through ballistic numerical simulation,ballistic characteristics is analyzed.Finally,the mechanism fo the body deceleration scheme is studied,and a method for optimizing design was proposed.For typical main body deceleration schemes, the deceleration effect is best achieved by designing the center of mass position at the pressure center position at a speed of 200 m/s and an angle of attack of 90° or 270°.

Key words： long range rocket; cluster muition; deceleration scheme; quaternion
