潜载无人水下航行器自航布放内弹道模型与仿真

通过对等截面鱼雷发射管自航布放无人水下航行器（UUV）过程中的受力进行分析,建立内弹道的数学模型,并对UUV自航布放的出管时间和出管速度进行实时仿真,同时,还对几种典型口径UUV自航布放过程中的阻力变化规律进行对比和分析,从理论上对UUV自航出管的可行性进行论证.仿真结果表明,选取500mm口径的UUV,通过潜艇的等截面鱼雷发射管进行自航布放完全可行.

Modeling and Simulation of the Interior Trajectory forUnmanned Underwater Vehicles During Swim-Out Launching

Based on the force analysis of Unmanned Underwater Vehicles（UUVs）during the swim-outlaunching process from torpedo tubes with uniform cross sections,the mathematical model of interior tra-jectory for the launching is established. The time cost and velocity of the launched vehicle are calculated,and the corresponding simulation curves are given. Meanwhile,the variational laws of the drag for UUV swith different dimensions are analyzed and compared,based on which the theoretical feasibility of swim-out launching is proved. Simulation results demonstrate that a diameter of 500 mm could well ensurethe vehicle to swim out from torpedo tubes without any problem.
