摘要
为了研究超空泡运动体水平面运动特性,将六自由度运动解耦,建立了有倾斜无侧滑的运动方程。考虑重力稳定方案情况下,分析了超空泡运动体的受力特性。提出两种水平面机动控制力产生方案,一是两自由度空化器方案;二是倾斜转弯方案。研究表明,采取重力稳定方案时,能保证运动体姿态及水平面弹道在扰动下不发散且以较小的幅值周期振荡。两自由度空化器的机动控制力产生效率高于倾斜转弯方案的效率。
In order to study the horizontal motion characteristics of supercavitating vehicles（SV）,the 6-DOF motion was decoupled and the dynamic equations of SV moving in horizontal plane with incline and un-sideslip were established.Considering the gravity stabilization scheme,the load characteristics of SV were analyzed.Two schemes of horizontal maneuvering control forces were advised,one is tow-DOF cavitator（TDOFC）;The other is BTT.The results show that the vehicle gesture and horizontal plane trajectory aren＇t divergent and periodic oscillations with small amplitude under small disturbance when owned gravitational stability scheme.The maneuvering control forces generation efficiency of TDOFC is higher than BTT＇s.
