一种过失速区飞行敏捷性评估方法的研究

A Method for Fighter Agility Assessment in Poststall Air Combat

在评估过失速机动飞行的敏捷性中，首先建立了具有过失速机动（ＰＳＴ）能力的战斗机Ｆ２的数学模型，对常规战斗机Ｆ１与ＰＳＴ战斗机Ｆ２的空战进行了数值仿真，计算了在两架战斗机中Ｆ２首先攻击时间（ｔ１）和攻击时间范围（ＴＷＩＦＥ）。结果表明，战斗机Ｆ２比Ｆ１更具有空中格斗优势，空战中发动机推力、迎角变化率、操纵规律和离轴发射角（μ０）等因素对战斗机过失速机动敏捷性有一定影响。

In this paper,mathematical model is established for a poststall technology(PST)fighter aircraft F2, and the air combat maneuvers between the PST fighter F2 and a conventional fighter F1 are simulated numerically,then the first firing time(t 1) and time within firing envelope(TWIFE)of the PST fighter are obtained.The results show that PST fighter F2 is superior in the combat,and the facts such as engine thrust,angle of attack rates,control laws and missile off boresight angle have some influence on fighter agility in poststall air combat.
