基于JSBSim的可视化飞行仿真系统

为了模拟一个具有高真实感飞行动力学模型,并且扩展后可以与联合作战仿真系统中其它武器装备进行交互的飞行器,本文使用Unity开发了一套基于JSBSim飞行动力学模型的可视化飞行仿真系统。该仿真系统先对输入设备的输入数据进行解析,然后利用JSBSim飞行动力学模型进行计算,最后根据计算结果对飞机的姿态、位置和速度等信息进行更新,可实现飞机姿态控制、状态信息及三维地形显示等功能。实验结果表明,开发的飞行仿真系统可以有效地模拟飞机的横滚、俯仰、偏转和加油等操作,实现飞机的可视化飞行仿真。经过扩展后,该仿真系统还可用于联合作战仿真中飞机的模拟。

Visual Flight Simulation System Based on JSBSim

In order to simulate an aircraft with high realism flight dynamics model, and after expansion, it can interact with other weapons in joint operation simulation. The paper develops a visual flight simulation system based on JSBSim flight dynamics model with Unity. The simulation system first analyzes the input data of the input device, then uses JSBSim flight dynamics model to calculate, and finally updates the aircraft attitude, position, speed and other information according to the calculation results. It can realize the functions of aircraft attitude control, state information and 3D terrain display. The experimental results show that the developed flight simulation system can effectively simulate the roll, pitch, yaw, refueling and other operations of the aircraft, and realize visual flight simulation of the aircraft. After expansion, the simulation system can also be used for aircraft simulation in joint operation simulation.
