研究飞机着陆近地告警系统,为了研究近地告警系统中近地告警曲线阈值的计算方法,保证飞机安全性,提出了近地告警系统,同时对飞机的飞行运动模型和二维地形模型进行了深入的研究并进行仿真计算,提出了一种新的近地告警曲线计算方法,即实验统计法,并以近地告警系统对过大地形接近率报警为例,利用实验统计法进行了报警曲线的计算和拟合。将实验得到的报警曲线和标准的报警曲线进行比较,可以看出实验所得到的报警曲线与标准报警曲线十分吻合,进一步验证了方法的可行性和正确性,可为系统提供一种准确、简单的告警曲线阈值研究方法。
In order to study the method of calculating the near-ground warning curve threshold of the near-ground warning system and ensure the safety of the aircraft, a near-ground warning system is proposed. At the same time, the aircraft’s flying motion model and two-dimensional terrain model are studied In-depth study and simulation calculation, a new method of calculating the near-ground warning curve is proposed, that is, the experimental statistical method. Taking the near-ground warning system as an example, the near- Calculate and fit. Comparing the experimental alarm curve with the standard alarm curve, it can be seen that the experimental alarm curve is in good agreement with the standard alarm curve, further verifying the feasibility and correctness of the method and providing an accurate and simple Alarm curve threshold research method.
