摘　　要：捷联惯导软件测试中,一般难以得到真实的航迹数据和飞行器的各种参数,针对要获得飞行轨迹数据和惯性器件输出参数,设计飞行轨迹仿真系统利用LabVIEW虚拟平台,将战斗机各种典型的飞行动作进行模块化处理,自由组合成一条飞行轨迹用于实时仿真测试。系统中的轨迹建模以几何算法为主,避免了采用差分算法时产生的计算误差,实现飞行航迹各参数的实时动态显示。对飞行中空气阻力对轨迹的影响进行了分析,加入空气阻力并建立新的模型,得到误差曲线。实验结果表明,系统能够实现轨迹的动态特性,同时空气阻力的影响也与理论相符,可以得到有用测试数据。It is difficult to get the real flight track and the flight data in strapdown inertial navigation system（SINS） software testing.This paper designed a method of emulation flight track based on LabVIEW platform.According to battleplan＇s practical flight track,this method modularized the various typical flight movements to individual parts,then combined them randomly to a flight track as needed for real-time emulation test.All the models based geometry algorithm in order to reduce the error,then displayed related flight track data dynamically.The author analyzed the influence of air resistance on the flight track,then compared it with the ideal emulation flight track,and got an error curve.The experimental results showed that this platform achieved the simulation and the influence of air resistance is consistent with the theorem.
