一种飞机的航迹模拟仿真算法

An Algorithm for Simulation of Flight Track Simulation

飞行仿真中,飞机航迹模拟没有考虑飞机是匀速还是变速,一般由简单的直线和圆组合来表示,这种表示算法较为理想化或简单化。为了建立逼真空情,实现复杂多样的飞行动作模拟,本文对飞机运动的数学模型进行研究,归纳总结飞机直线飞行算法,针对飞机转弯航迹过于理想和简单化提出一种新的模拟算法来模拟飞机转弯航迹。将飞机匀速和变速转弯用一种算法实现,增加新的转弯方式并提高飞机航迹多样性。最后将新算法替代老算法在航管模拟训练系统中进行应用与仿真,与真实飞机航迹数据对比,证实新的算法可以模拟出变速转弯航迹,并使整体航迹更加接近真实。

In flight simulation,the aircraft track simulation does not take into account the aircraft is uniform speed or change speed. It is usually represented by a simple combination of straight lines and circles. This algorithm is generally ideal or simplified. In order to establish a realistic implementation of complex air situation and flight simulation,mathematical model of aircraft motion is studied. The aircraft linear flight algorithm is summarized,and a new simulation algorithm is proposed to simulate the turning track of aircraft in order to simplify the turning track of aircraft. A new method of turning and increasing the diversity of aircraft tracks is achieved by using an algorithm for uniform and variable speed turns of an aircraft. The application and simulation of the new algorithm in ATC simulation training system,compared with the track data of the real aircraft,confirm that the new algorithm can simulate the transmission turning track,and make the whole track closer to the true.
