摘　　要：在分析有关资料的基础上,对某型航行器的入水弹道进行了详细计算。在考虑入水空泡的基础上,建立了入水过程的运动学和动力学模型,在Matlab环境下进行了仿真计算,求解了航行器带空泡航行阶段的流体动力,给出了2种外形航行器在2种典型工况下的入水深度、姿态和速度随时间的变化。结果表明,展开翼对航行器的空泡段时间影响不大,对入水弹道有非常明显的影响。On the basis of analyzing the relevant information,the paper calculated underwater trajectory of a certain type of airborne vehicle in detail. On the basis of considering entry cavity,we established the kinematics and dynamics model of the water process,and the simulation calculation was carried out in Matlab environment on solving the aircraft with cavity navigation phase fluid power,and two kinds of shape craft under two typical conditions of the water depth,posture and speed change over time were given. The results show that the spread wings of the airborne vehicle has a little influence on cavity time and has a very obvious effect on water ballistic.
