无动力运载器水弹道特性计算

Computing of Water Ballistic Trajectory Characteristic for Unpowered Vehicle

针对无动力运载器浮心重心距、发射离管速度和折叠尾翼解锁距离3种设计要素参数值一定的变化范围,对一种无动力运载器的水弹道特性分别进行了仿真计算和分析比较,获得了3种设计控制参数变化对运载器出水速度、俯仰姿态及弹道袋深等的影响趋势,对水下运载器性能设计具有一定指导作用。

Aimed at certain variation range of parameters for three kinds of essential design factor in distance of gravity center of buoyant centre,launching velocity leaved from canal and deblocking distance of fold empennage？on unpowered vehicle,the paper made respectively the simulation computing and analysis comparison for each kind of water ballistic trajectory characteristic of unpowered vehicle.The results showed that three kinds of influence trend of design control parameter variation have been obtained for speed leaved out of water,pitching attitude and pocket depth of ？ballistic trajectory and so on.It has certain guidance significance for performance design of underwater vehicle.
