摘　　要：针对在空中飞行模拟中变稳飞机与模型飞机的差异导致模拟逼真度下降的问题,提出一种相似性匹配技术,使驾驶员感受到一个更为接近模型飞机响应的飞行动力学特性。从理论上研究相似匹配技术,推导出合适的模型状态的转换逻辑;将转换逻辑加入到数值仿真试验和人机闭环地面试验中对其验证。结果表明,通过采用相似性匹配技术和调节跟踪参数值,整体跟踪效果得到改善,模拟逼真度得到显著提高。For the problem of decreasing the simulation fidelity which caused by differences between variable stability aircraft（ VSA） and model aircraft in the air flight simulation,a method of similarity matching technology was proposed to make the pilot could feel a flight dynamic characteristic closer to the model aircraft response. The similarity matching technology was theoretically studied,and the appropriate transformation logic of model states was derived; and the transformation logic was verified in the numerical simulation tests and human-machine closed-loop ground simulation tests. The results show that,by using similarity matching technology and adjusting these tracking parameters,the overall tracking effect is improved,and the simulation fidelity is enhanced greatly.
