摘　　要：针对飞行器航迹研究,捷联惯性导航系统的性能评估需要飞行轨迹数据和相应的惯性器件参数,但真实飞行数据较难获得,且不易灵活调整。为了仿真实际的速度、位置、姿态等飞行数据,设计了三自由度飞行器模型的航迹发生器。在建立三自由度飞行器模型的基础上,设计了飞行器的航路飞行控制方案,并实现了多航路点的飞行仿真与导航验证。实验结果表明,算法所产生的飞行轨迹数据和惯性器件数据过渡平滑、符合飞行动力学特点,并且通过调整参数设置能够方便地制定航迹,对于分析和提高捷联惯性导航系统性能具有重要的理论参考价值。The performance appraisal process of the INS（inertial navigation systems） needs flight track data and corresponding inertial component output parameters,which are usually difficult to obtain and hard to change flexibly.To simulate the actual flight data,a track generator based on 3-DOF（Degree of Freedom） aircraft model is put forward and realized.After modeling the 3-DOF aircraft,a program of aircraft flight routes is designed,flight simulation and navigation authentication based on multi way points are realized.The simulation results show that the flight track data and inertial component output parameters generated in the paper are smooth transition and consistent with the characteristic of flight dynamics,and users can easily adjust tracks by changing the parameters.Track generator in the paper has great theoretical and referrible significance for improving INS performance.
