飞行动力学是飞行仿真的基础。首先建立了战斗机质心运动和绕质心转动的数学模型。经过对比和筛选,系统选取了急转弯、桶滚、破S机动、伊曼回旋、低强势回旋、高强势回旋和眼镜蛇机动等7种典型的空战机动动作并在Vega和MFC平台下实现了该飞行仿真系统。该系统既可以直观地展示空战中基本机动动作,也可以作为导弹制导系统的重要子系统完成制导算法的验证等工作。
The Flight Dynamics Model(FDM)is the basis of flight simulation.In this paper,the centroid motion and turning model of aircraft is established.Seven maneuver movements including break turn,barrel roll,split S,immelman turn,low Yo-Yo,high Yo-Yo,cobra maneuver is choose in the system.The flight simulation system is implemented using Vega and MFC platform in the end.The system can display the basic maneuver movements in air combat.It can also be used to validate the guide algorithm in missile guide sytem.
