飞机横航向飞行品质地面模拟试验

给出了飞机空间全姿态运动方程和发动机推力的数学模型；介绍了飞机横航向飞行品质指标的计算方法并进行了计算，其结果与作图法的结果相比误差较小，表明计算方法正确、可靠。同时还讨论了目标瞄准设计的基本原理。最后提出了飞机飞行品质指标的五种试验方法，通过模拟试验，证明所提出的试验方法正确、有效，可用于飞机飞行品质的研究，对飞机设计和其它飞行试验课题也有参考价值。

The Ground Simulation Experiment of Aircraft Lateral Directional Flying Qualities

In this paper,the mathematical models of the aircraft motion with all attitudes and its engine thrust is given.The calculation method of lateral directional flying qualities specification is also presented.The calculated results error is smaller than artificial drawing method's error,this shows that the calculation method is correct and reliable.Moreover,the basic principle of the target aiming design is discussed.Finally,five simulation experiment methods of the flying qualities are described,and they have been proved to be correct and useful by the experiment.These methods can be used to study the flying qualities,and provide the references for aircraft design and other flight test.
