超空泡射弹弹道特性影响因素仿真研究
Simulation and research on influencing factors of supercavitation projectile trajectory characteristic
摘要
Abstract
Kinematic and dynamic model for the underwater supercavitation projectile is established and simplified, based on cavity model hypothesis and the independence principle of the cavity expansion, the coupling relation between the cavitation number and velocity along with depth and the critical cavitation number are made certain, so the ballistic characteristics of the underwater supercavitation projectile are simulated and researched. The simulation result shows that the own mass and launch depth have great influence on the effective attack range of the underwater projectile, the relationship between the effective attack range and the own mass is linear increase, and the relationship between the effective attack range and the launch depth is similar to linear decrease; in practical operation, the influence of the launch depth on the effective attack range must be considered, and the effective attack range can be increased by increasing properly the own mass of the projectile.关键词
