基于低空风预测模型的安全航迹规划方法

A Safe Track Planning Method Based on Low Altitude Wind Prediction Model

针对低空救援过程中地形与低空风对救援航空器的航迹的综合影响,提出基于低空风预测模型的安全航迹规划方法。建立低空风预测模型;通过预测模型得出救援区域的风场数据,并提出基于Dijkstra算法的航迹修正方法;以四川省汶川县为例,建立低空救援仿真环境,完成航迹规划的对比分析验证。实验结果表明,方法得出的规划航迹不仅满足安全要求,而且在飞行时间和航行路程方面更有优势。

Aiming at the influence of terrain and low air wind on the track of rescue aircraft in the process of low altitude rescue,a safe track planning method based on low altitude wind prediction model is proposed.First,establish low air forecast model;Then,the wind field data of the rescue area are obtained by predictive model,and the track correction method based on Dijkstra algorithm is proposed.Finally,taking Wenchuan County of Sichuan Province as an example,a low altitude rescue simulation environment was established to complete the comparative analysis and verification of track planning.The experimental results show that the planned track obtained by this method not only satisfies the safety requirements,but also has more advantages in flight time and voyage distance.
