舵面破损对飞机轴间运动耦合飞行品质的影响

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.
