战斗机俯仰瞬态敏捷性与飞行品质关系研究

A STUDY OF RELATIONSHIPS BETWEEN FIGHTER PITCH TRANaENT AGILITY AND FLYING QUALITIES

采用飞机纵向运动的非线性数学模型和线化模型分别进行数字仿真，确定俯仰瞬态的敏捷性尺度。结果表明在同样驾驶员操纵规律输入下，两种模型仿真获得的敏捷性尺度相当接近。然后采用线化模型来研究俯仰敏捷性与飞行品质的关系。最后导出了近似计算俯仰敏捷性尺度的公式。

In this paper,nonlinear and linear mathematical models of motion are used toevaluate pitch transient agility metrics for a fighter.Computer sirnulation results of bothmodels show the agility metrics are almost identical in same control law. Then relationshipsbetween pitch transient agility and flying qualities are studied using linear mathematicalmodel of motion. Finally,the approximation formulas of pitch transient agility metrics arederived.
