摘要: 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.

Abstract: The flying qualities evaluation of high angle of modern attack aircraft lacks of quantitative evaluation criteria. Based on the conventional flying qualities criteria, with mission-oriented flying qualities evaluation method, various flying by wire systems with different transfer function parameters were tested, by subjective evaluation method and objective evaluation method. Thus, quantitative longitudinal and lateral flying qualities criteria for high angle of attack aircraft were developed. The result of comparison between the conventional flying qualities evaluation criteria and the quantitative evaluation criteria for high angle of attack aircraft shows that with higher short period damping ratio and control anticipate parameter in longitudinal and higher roll mode time constant in lateral, the flying qualities for high angle of attack aircraft get better. Therefore, the developed criteria is more adaptable in evaluation the flying qualities for the high angle of attack aircraft. This new criteria could be used as a guideline when designing modern air fighters.

Key words: high angle of attack, flying qualities, criteria for evaluation, mission-oriented, air fighter
