摘要: 为研究舵面破损对电传控制飞机轴间运动耦合飞行品质的影响,选取了能够反映飞机多轴运动耦合特性的飞行品质评定任务,建立了舵面破损飞机的飞行动力学模型,选取了适用于表征飞机轴间运动耦合程度的特征参数,形成了基于任务的角速率指令式电传控制飞机轴间运动耦合飞行品质的评定方法。采用该方法对具有不同舵面破损程度的算例飞机开展了飞行品质评估试验,得到了能够量化舵面破损对角速率指令式电传控制飞机飞行品质影响的特征参数取值规律。研究结果对于舵面破损情形下飞机飞行安全与作战效能评估等均有一定的理论参考价值。

Abstract: To examine the influence of control surface damage on flying qualities of inter-axis motion coupling of wire aircraft, we select the demonstration maneuver which can reflect the coupling characteristics of multi-axis motion and establish the flight dynamics model of the aircraft with control surface damage. The flying quality parameters suitable for coupling motion degree characterization are determined, and the evaluation method of flying qualities of the mission-oriented inter-axis motion coupling of the wire aircraft is realized. Based on the method, flying quality evaluation experiments are conducted on aircraft with different damage conditions, and the boundaries of characteristic parameters which can quantify the influence of the control surface damage on flying qualities of inter-axis motion coupling are obtained. The study provides theoretical reference for the evaluation of flight safety and combat effectiveness of the aircraft with damaged control surface.

Key words: control surface damage, inter-axis motion coupling, flying qualities, mission-oriented, combat effectiveness
