Abstract

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.
