摘　　要：本文研究了推力可调空空导弹在复杂场景下的攻击能力和潜在优势。论文设想了一种具有推力可灵活调节特征的空空导弹概念,针对此类概念建立了三维轨迹动力学模型,引入轨迹优化方法研究空空导弹的攻击能力。针对目标丢失再捕获和发射后变更目标两种作战场景开展了飞行性能仿真研究,并且与传统固体火箭动力的空空导弹进行了对比。仿真结果表明:在目标丢失再捕获的场景下,当初始弹目距离为70~100 km时,推力可调空空导弹允许的目标最大丢失时长比传统动力空空导弹增加大约20~40 s,允许的目标最晚丢失时间比传统动力空空导弹晚约20 s;在发射后变更目标的场景下,当初始弹目距离为70~100 km、新旧目标横向距离为30 km时,推力可调空空导弹允许的最晚目标变更时间容忍裕度比传统动力空空导弹推迟大约10~70 s。The attack capabilities and potential advantages of thrust adjustable air-to-air missiles in complex combat scenarios is explored.This paper envisions a concept of thrust adjustable air-to-air missiles and establishes a three-dimensional trajectory dynamics model,then employs trajectory optimization methods to study the attack capabilities of thrust adjustable air-to-air missiles.Numerical simulation is conducted for two envisioned combat scenarios:target loss recapture scenario and target change scenario after launch,and their capabilities are compared with traditional powered air-to-air missile.Simulation results indicate that in the target loss and recapture scenario,when the initial missile-to-target distance is between 70 to 100 km,the maximum allowable target loss duration of thrust adjustable air-to-air missiles is increased 20 to 40 s approximately than that of traditional solid-propellant air-to-air missile,and the latest allowed target loss time is about 20 s later than traditional air-to-air missile.In the target change after launch scenario,when the initial missile-to-target distance is between 70 to 100 km and the lateral distance between the new and the old targets is 30 km,the tolerance margin of latest target change time for thrust adjustable air-to-air missiles is delayed by approximately 10 to 70 s compared to traditional solid-propellant air-to-air missile.
