Analysis on Influence of Attached Cavity on the Traj ectory of Submarine Launched Missile
摘要
Abstract
To study the influence of attached cavity on the traj ectory of submarine launched missile (SLM),the motion equations of SLM was established,and the external force and external moment were analyzed according to the characteristic of pressure distribution.The transverse force model at rear of nose cavity was established.By modeling hydrodynamic forces and solving the movement equation of missile,traj ectory results under different conditions were obtained.The results obtained by traj ectory calculation model were compared with the experiment results under the same conditions.The results show that transverse force at rear of cavity caused by cavity’s asymmetric development has great influence on the missile’s being righted.Cavity length difference between incident and suction side has more effect on pitching angle and pitch rates of exiting water than launched depth and tube-exit velocity.关键词
