摘　　要：针对飞机生存力设计是一个效益与代价的综合权衡过程,提出了一种包含飞机敏感性、易损性和作战能力的生存力权衡设计模型。推导了考虑飞机作战能力的生存力计算公式,基于雷达发现概率、导弹击中概率、破片杀伤概率以及飞机作战能力的计算模型,建立了以飞机生存力最大为目标,以重量代价为约束条件,以飞机雷达散射面积、装甲质量以及挂载武器质量为优化变量的飞机生存力权衡设计模型,并应用粒子群优化算法对模型进行求解。算例分析表明,所建立的模型符合实际、易于实现,可以为飞机生存力的权衡设计提供参考。Since the design of aircraft survivability is a tradeoff process of benefits and cost, a tradeoff model of aircraft survivability including aircraft susceptibility, vulnerability and aircraft combat capability is proposed. The survivability formula considering aircraft combat capability is deduced. Based on the calculation model of detection probability of the radar, hitting probability of the missile, killing probability of the fragment and combat capability of the aircraft, the tradeoff model is established, which takes the maximal aircraft survivability as the optimization objective, takes the weight as the constraints, and takes radar cross section （RCS）, the mass of armor and the mass of airborne weapon as the design parameters, then the model is calculated by particle swarm optimization algorithm. Simulation results show that the method is effective and feasible, which can provide references for tradeoff design of aircraft survivability.
