通用航空器飞行轨迹模型研究

Research on Aircraft Conflict Model in Terminal Area Based on Bayesian Algorithm

目前我国低空空域的改革已经进入深化阶段,为评估低空空域的安全风险,有必要对通用飞机的轨迹进行研究。本文提出了非管制空域内通用航空器的自由飞行轨迹模型。模型根据通用飞机的目标航向和航向周期对通用飞机的水平轨迹进行计算,根据目标俯仰角和俯仰周期对通用飞机的垂直剖面进行计算,并通过几何方法详细计算了通用飞机的转弯轨迹。模型验证显示,该模型产生的通用飞机模拟轨迹,与实际轨迹具有很高的相似程度。模型可为低空空域的安全评估提供支持。

At present, China＇s low altitude airspace reform has entered a deepening stage. In order to assess the safety risk of low altitude airspace, it is necessary to study the trajectory of the general aircraft. This paper puts forward the model of free flight trajectory of general aircraft in uncontrolled airspace. In this model, horizontal trajectory is calculated based on the target course and heading period, and vertical profile of general aircraft is calculated according to the target pitch angle and pitch cycle. The model also calculates the turning track of general aircraft in detail by using geometrical methods. Model verification shows that the model has a high degree of similarity with the actual trajectory. It can provide support for the safety assessment of low altitude airspace.
