飞行器机动规避空空导弹生存力仿真研究

飞行器规避空空导弹的逃逸机动策略对于提高其本身的生存力至关重要。为了得到飞行器规避敌方空空导弹的机动方式和过载的最优解,对空空导弹和飞行器等进行数学建模,并通过数字仿真对机动规避生存概率进行计算分析。当飞行器在低、中、高空以不同的速度,进入角与来袭的空空导弹遭遇时,通过飞行器以不同机动方式、机动过载进行对抗,统计了飞行器有效逃离攻击的生存概率,得到了机动方式和过载的最优解。飞行器的机动方法正确,机动过载增大到一定数值其生存概率达到 100%。此时的机动过载为飞行器重量设计、主传力结构布置等提供依据。

Simulation Study on Survivability of Aircraft Maneuvering toEvade Air-to-Air Missile

The escape maneuver strategy of air-to-air missile is very important to improve its surviv-ability. In order to get the optimal solution of maneuvering mode and overload of aircraft avoidingenemy air-to-air missile , mathematical modeling of air-to-air missile and aircraft is carried out, andthe survival probability of maneuvering escape is calculated and analyzed by digital simulation. Whenaircraft encounters air-to-air missile at different speeds , angles of entry and attack at low ,medium andhigh altitude , the survival probability of flight effectively escape attack is calculated by different ma-neuvering mode and maneuvering overload. The optimal solution of maneuvering mode and overloadis obtained. The maneuverability of the aircraft is correct,and the survival probability of the vehiclereaches 100 % when the maneuverability overload increases to a certain value. At this time .the maneuvering overload provides the basis for the weight design of the aircraft and the arrangement of themain force transmission structure.
