针对现代战斗机大迎角飞行品质缺少量化评定准则的问题,在常规飞行品质评定准则的基础上,采用基于任务的飞行品质评定方法,通过主观评估和客观评估,对多个具有不同电传操纵特性的飞机进行飞行品质评定,由此建立了定量的横向和纵向的大迎角飞行品质评定准则.将所得到的基于任务的大迎角飞行品质评定准则与常规飞行品质评定准则对比,结果表明:具有更大阻尼比和更大短周期操纵期望参数,在横向具有更大滚转模态时间常数的飞机,其大迎角飞行品质等级更优.建立的这一准则更适用于战斗机大迎角飞行的飞行品质评定研究,并可作为现代战斗机的设计标准.
In view of the lack of quantitative assessment criteria for the flight quality of modern fighter planes at high angles of attack, based on the conventional flight quality assessment criteria, a mission-based flight quality assessment method is adopted to evaluate the flight quality of multiple aircraft with different fly-by-wire characteristics Of the aircraft flight quality assessment, which established a quantitative horizontal and vertical high-angle flight quality assessment criteria.Based on the task-based high-angle flight quality assessment criteria and conventional flight quality assessment criteria comparison, the results show that: With a larger damping ratio and greater short-period manipulated desired parameters, aircraft with larger roll modal time constants in the transverse direction have better flight qualities at high angles of attack, and are more applicable to fighter planes at high angles of attack Flight flight quality assessment research, and can be used as a modern fighter design standards.
