过失速机动与快速机头瞄准能力

Post-Stall Maneuverability and Rapid Nose Pointing Capability

过失速机动飞机具有快速机头瞄准能力。在格斗过程中，可以获得攻击敌机的有利时机，飞机处于开火状态的时间（ＴＷＩＦＥ）是衡量过失速飞机格斗优势的一个敏捷性尺度。现通过对两种典型格斗过程的计算，讨论了首次可实行攻击时刻ｔ１的重要性，提出了ｔ１作为衡量格斗优势敏捷性尺度的可行性，并进一步分析了迎角变化率（ａ）和允许离轴发射角（μ０）等因素对这两个尺度的影响。计算和分析表明：ＴＷＩＦＥ和ｔ１均可作为衡量过失速机动飞机敏捷性的尺度，并具有同等的重要地位。

Post-stall technology (PST ) aircraft has the rapid nose pointing capability and the advantage of attacking the adversary. 'Time within firing envelope(TWIFE )' has been used as a measure of PST fighter's combat advantage. Based on thecalculations of two typical combat processes, the first firing time t1 was discussed andthought as an important agility metric to measure combat advantage in this paper. Theimpacts of attack angle velocity a and missile off-boresight angle μ0 on metrics t1 andTWIFE are discussed.
