小型水下运载器快速上浮导弹发射过程扰动分析

Disturbance Analysis of Missile Launching Process during Fast Floating of Light Underwater Vehicle

摘要:

区别于传统潜艇发射导弹，小型水下运载器由于尺寸小、重量轻、上浮速度快，导弹发射过程对其动力学特性具有重要影响。针对小型快速上浮运载器，对上浮过程、发射过程及开盖过程扰动进行建模，并对典型上浮发射导弹过程进行仿真分析。结果表明，开盖及发射过程对运载器弹道及姿态的扰动较小，而对上浮速度影响较大，发射后运载器控制效率显著下降。

Abstract:

Missile launching process has an important effect on kinetic characteristic of light underwater vehicle compared to traditional submarine launching missile due to its small size，light weight and fast floating process. Aiming at light and fast floating underwater vehicle，a disturbance model of floating，launching and uncapping process is established. In addition，the typical floating and missile launching process is simulated and analyzed. The simulation results indicate that the disturbance of uncapping and launching process has a small effect on trajectory and attitude of vehicle，but has great influence on floating speed. The efficiency of control system degrades significantly after launch.
