摘要
灭火飞机一直是森林草原大型火灾的重要消防力量,然而火场环境复杂危险,导致灭火飞机事故频发,确定灭火飞机在火场中的安全飞行区域尤为重要。本文提出了灭火飞机在火场环境的安全飞行边界分析方法,可识别火场环境对灭火飞机飞行安全的关键影响因素,采用火场仿真与火场实测数据相互校验的方法,获得大体量且准确度高的火场环境数据,在此数据的基础上综合各影响因素绘制安全飞行边界,最终确定飞机的安全飞行区域。该方法一部分解决了灭火飞机试验、试飞及运营阶段的航迹规划问题,可将安全飞行边界作为基准,进一步探索更优的灭火作业位置和路径,缩短灭火飞机研制周期,提高飞行安全性,为灭火飞机的高效、安全运行提供有力支持。
Fire-fighting aircraft has always been an important force for large forest and grassland fires.However,the complex and dangerous environment of the fire leads to an endless stream of aircraft accidents.It is particularly important to determine the safe flight area of the fire-fighting aircraft in fire.This paper puts forward an analysis method of the safe flight boundary of fire-fighting aircraft in fire,and identifies the key influencing factors of fire en-vironment on flight safety of fire-fighting aircraft.The method of mutual verification between fire simulation and measured fire data is used to obtain large volume and high accuracy of fire environment data.On the basis of the data,the safety flight boundary is drawn by integrating various influencing factors,and finally the safe flight area of the aircraft is determined.This method partially solves the path planning problem of the fire-fighting aircraft in the test,test flight and operation stages.The safe flight boundary can be used as a reference to further explore the opti-mal fire-fighting position and path,shorten the development cycle of fire-fighting aircraft,and improve flight safety.
