摘要:

大型固定翼灭火飞机是应对森林火灾最有效的工具之一。首先针对中国缺少大型灭火飞机投水灭火飞行仿真系统的现状,基于水陆两栖灭火飞机投水灭火任务流程,对投汲水灭火仿真任务子系统、灭火飞机投汲水灭火仿真场景构建、投水数据处理与灭火效能评估方法进行了研究,设计和构建了一种水陆两栖飞机灭火飞行仿真系统,实现了大型灭火飞机投水灭火任务全流程飞行仿真。其次通过使用K-S检验方法对仿真飞行投水数据与真实飞行试验投水数据进行统计学检验,证实了本仿真系统具有较高的仿真真实度。最后还研究了在灭火飞行仿真中投水速度和投水高度对投水覆盖面积、投水均匀度和投水有效利用率3个灭火效能参数的影响,为灭火飞机指挥员进行投水方案的制订提供了支撑。本文成果对于提高灭火飞机飞行员培训效率,节省培训费用,节约灭火飞机飞行试验费用,缩短飞行试验的时间,加快中国森林航空消防力量建设具有参考意义。

Abstract:

Large fixed-wing firefighting aircraft are one of the most effective tools to deal with forest fires. Nevertheless, China still lacks a fire-fighting aircraft flight simulation system for water dropping mission. Based on the amphibious fire-fighting aircraft fire-fighting task process, this paper researches the fire-fighting simulation task subsystem, fire-fighting aircraft water-fighting simulation scenario construction, water-fighting data processing and fire-fighting effectiveness evaluation methods, and then constructs an amphibious aircraft fire-fighting flight simulation system to realize the whole process of large fire-fighting aircraft water-fighting task flight simulation. Furthermore, by using the K-S test method to statistically check the simulation flight water drop data and the real flight test water drop data, this paper confirms that the simulation system has a high degree of simulation realism. Besides, this study investigates the effects of water delivery speed and water delivery height on three firefighting effectiveness parameters: water delivery coverage area, water delivery uniformity and effective water delivery utilization rate in firefighting flight simulation, which provides support for firefighting aircraft commanders in the formulation of water delivery plans. The results of this paper are of great significance to improve the training efficiency of fire-fighting aircraft pilots, save training costs, shorten the time of flight test and accelerate the construction of forest aviation fire fighting force in China.
