基于任务的军用飞机闭环动 特性 求

Traditional aircraft flying qualities criteria provide requirements for stability and control characteristics of different military aircraft types in different flight stages, but it is hard to apply the criteria directly to the design of flight control laws for military aircrafts in specific combat missions. In the mission-oriented flying qualities evaluation approach, demonstration maneuvers are designed based on the requirements of the actual flight mission. Through the objective test results of ground simulation tests or flight tests, and considering the subjective evaluation of pilots, the flying qualities grade of military aircraft can be comprehensively evaluated. In this review paper, the process of mission-oriented flying qualities evaluation is introduced, and the main design indexes of the evaluation mission are discussed. The mission-oriented flying qualities evaluation method is applied to evaluate the flying qualities of aircraft in four typical missions and scenarios:short-range air combat, aerial refueling, air-to-ground attack, and control surface damage. The requirements of suggested closed-loop dynamic characteristics are given. In addition, the differences between these requirements and conventional flying qualities criteria are compared, and the effectiveness of these suggestions are analyzed. The research conclusions in this paper can provide a theoretical reference for determination of the mission-oriented flying qualities criteria and the flight control law design of military aircrafts.
