RESEARCH AND DESIGN OF AMPHIBIOUS AIRCRAFT FIRE-EXTINGUISHING SIMULATION MANAGEMENT SYSTEM BASED ON DIS

Forest fires are devastating to forest resources and ecosystems and large fire fighting aircraft is one of the most effective tools for forest fire fighting. Aiming at the gap between the use experience of large fire-fighting aircraft in China and the simulation of fire-fighting flight by water drop, this paper studied and designed a firefighting simulation management system for amphibious aircraft with high simulation performance and high real-time performance by using Windows operating system and Qt user graphical interface development framework. Firstly, the characteristics of the Distributed Interactive Simulation System(DIS) and the requirements of the aircraft fire extinguishing simulation management system were analyzed in this paper, and then a software development framework for the aircraft fire extinguishing simulation management system based on the Model-View-Control(MVC) and modular ideas was proposed. The system was divided into six modules to properly handle the relationship between task scheduling, data management, dynamic model invocation, and human-computer interaction, which not only realized the required functions of the system but also improved the stability of the system. Finally, the software of the aircraft fire extinguishing simulation management system was developed. After testing the software, the test results showed that the fire extinguishing flight simulation management system can meet the mission requirements and has high real-time performance and simulation effects.
