危险天气下基于多重Morphin算法的终端区三维实时改航方法

3-D Real-Time Deviation Method for Avoiding Hazardous Weather in Terminal Airspace Based on Morphin Planning Algorithm

基于多重Morphin算法,建立了终端区三维实时改航方法。该方法首先根据航空器当前飞行状态按不同的转弯角和爬升/下滑角生成一组弧线,随后在每条弧线的末端按同样方式反复运行,形成若干条由弧线组成的路径,最后对所有路径进行综合评估,找到当前时刻的改航路径。算例分析表明,该方法提供的改航路径可以保证航空器运行的安全与高效,在危险天气出现时更加充分地利用终端区空域资源,同时计算时间短、可行性高。

A 3-D real-time deviation method in terminal airspace is presented based on the multiple Mor- phin planning algorithm. Firstly, a set of arcs is generated with various changes of heading, and angles of climb/descent in accordance with present attitude. Then each end of the arcs is carried out such oper- ation to regenerate candidate deviation routes. Finally, the optimal route is selected with comprehensive assessments. The example proves the reliability and the efficiency of the method in providing safe and efficient deviation, and the improvement of the usage of hazardous-weather-effected terminal airspace.
