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。
Aiming at the problem that the difference between the stabilized aircraft and the model aircraft in the flight simulation leads to the decrease of the simulation fidelity, a similarity matching technique is proposed to make the pilot feel a flying dynamics more close to the response of the model aircraft. The similar matching technique is studied theoretically to derive the conversion logic of the appropriate model state. The conversion logic is added to the numerical simulation and human-computer closed-loop ground test to verify it. The results show that by adopting the similarity matching technique and adjusting the tracking parameter values, the overall tracking effect is improved and the simulation fidelity is significantly improved.
