短周期运动飞行品质的几种判据

飞机纵向短周期运动是影响其飞行品质的关键因素，根据国外近年来所进行的研究，综合，发纳出六种适用于小迎角飞行的短周期飞行品质标准，基于等效系统的控制期望参数（ＣＡＰ）等准则依然适用，并作了增补；对于不能用低阶系统等效的飞机提出了诸发带宽准则等相应判据，这六种准则各有其侧重点和适用范围，较全面地反映了飞机短周期运动特性，共同完成对飞行品质的评判和预估。

Some Criteria of Aircraft Short Period Flying Qualities

Aircraft short term response is a crucial element of piloted vehicle flying qualities.This paper consolidates and offers six criteria for evaluation short term pitch response of low attack angle basing on the resent foreign research.The equivalent system approach is still available and new criteria based on it are developed. Meanwhile, criteria such as bandwidth are provided for systems without proper equivalent counterparts.There are strengths and weaknesses for each criterion depending on aircraft classification and flight phase. All six criteria are used to rate and predict the aircraft handling qualities.
