摘要: 为了精确计算具有航迹可编程能力飞行器从起飞至抵达目的地的航程,提出了一种航程计算方法。根据航迹可编程飞行器飞行过程的特点,将航程计算分解为起飞段和巡航段,分别建立了飞行器水平面内扇面转弯、垂直面内程序下滑和巡航段多航路点曲线转弯航迹描述数学模型,采用几何方法分别给出了各段航程计算方法,并归纳推广至具有N个航路点的复杂航迹的航程计算。系统验证表明:该方法计算的飞行器航程理论值与飞行器导航系统实测真值误差较小,具有计算速度快、精度高的特点。

Abstract: To accurately calculate the voyage of the aircraft with the track programmable capability from the takeoff to the destination, a simplified method of calculating the voyage is proposed. According to the characteristics of the flight path of the programmable aircraft, the flight calculation process is decomposed into the flight section and the cruise section, the aircraft in plane turning model, the vertical in plane program decline model and the cruise section of multi way road curve description mathematical model are established. The geometric method is used to give the calculation method of each voyage, and the proposed method is generalized to the complex trajectory with N waypoints. The system verification shows that the error between the calculated value of the aircraft range and the measured value of the aircraft navigation system is very small, and it has the characteristics of fast calculation and high precision.

Key words: track programming, in-plane turning, program downtime, multiple waypoints, geometric method, voyage calculation, simulation verification
