能量理论在空空导弹攻击效果评价中的应用

The Application of Energy Theory in the Evaluation of Air-to-air Missile Attack Effect

针对现有空空导弹攻击效果评价方法局限于运动学方程的问题,借鉴能量机动理论,提出从能量角度评价导弹攻击效果的方法。现有方法没有考虑过载与能量消耗的关系,基于此提出机动强度来描述一段时间内飞行器的能量消耗,推导出导弹与目标机动强度的对应关系,并以此对导弹攻击效果进行评价。同时为了体现不同机动强度对飞机的后续影响,又提出机动潜力用以评价剩余机动能力。仿真算例验证了评价指标的有效性。研究结果表明,机动强度可以弥补现有评价理论在能量方面的缺失,有利于进一步提升空空导弹攻击效能评估的准确性。

In view of the problem that the existing air -to -air missile attack effect evaluation method is limited to the kinematics equation, referencing the energy -maneuverability theory into consideration,a method of evaluating missile attack effect from energy angle is proposed. Existing methods do not consider the relationship between the overload and the energy consumption. On that basis, this paper puts forward the maneuvering intensity to describe the energy consumption of the aircraft after a period of time, deduces the relationship of intensity of maneuvering between the missile and the target, and evaluates the effect of missile attack. In order to show the subsequent influence of different maneuvering intensity on the aircraft, the maneuvering potential is also put forward to evaluate the residual maneuvering. Simulation result gives credit to the evaluation index. The result of research shows that maneuvering intensity can make up for the absence of the existing evaluation theory in energy and is helpful to improve the accuracy of air-to-air missile attack effect evaluation.
