为保证歼击机投放武器外挂物的投放安全性,采用基于欧拉方程的投放数值模拟与风洞试验相结合的方法,对武器外挂物的投放安全性分析方法进行研究。文中以某歼击机投放某型滑翔弹为算例进行分析,仿真计算的滑翔弹姿态角和投放轨迹与风洞试验数据基本吻合。通过仿真计算对风洞试验进行了补充。应用该方法对滑翔弹的投放安全性进行了全面的分析,保障了飞机空中投放滑翔弹飞行试验的安全,同时验证了分析方法的可靠性。

In order to insure release safety for external stores of weapon released from jet fighter, the method combining numerical release simulation based on Euler equations with the wind tunnel experiments was proposed to analyze release safety for external stores of weapon. This paper uses some kind of glider bomb released from the jet fighter as example. The simulated attitude angles and release trajectories are consistent with wind tunnel experiment results. The numerical simulation replenishes the wind tunnel experiments. Comprehensive analysis of the release safety insures success of flight test. It also confirms dependability of the analytical method.
