基于实现预期空战机动的飞机运动模型

Aircraft Dynamic Model for Realizing the Expected Air Combat Maneuvers

在研究空战战术和作战效能时,往往先确定期望的机动动作,继而解算预期动作的飞机动力学参数。针对如何建立既具有准确动力学特性又能适应空战机动研究的空战机动模型的问题,建立了实现预期空战机动的简化飞机动力学模型,用机动过载大小和方向、发动机状态或速度作为机动动作的输入量,较好地将飞行员的机动意图转换成机动控制的输入。同时,考虑飞机的实际限制,确定了飞机六自由度参数,并以飞机刚体六自由度模型为参照进行了机动仿真,比较了仿真结果。结果表明文中模型仿真精度高,简单实用,适用于空战仿真研究。

In air combat tactics and efficacy researching,it is often first to define the expected aircraft＇s maneuvers,then the dynamics parameters related to the maneuvers need to be determined.Aimed at this problem,the paper discusses the air combat maneuver modeling which has accurate dynamics property and also suits the need of air combat research.The simplified dynamic model is set up,in which the imports are aircraft＇s load vectors and engine＇s state or aircraft＇s velocity are taken as the imports of maneuverable action,these imports have close connection with air combat maneuver description and well transform the intension of pilot into the maneuver＇s control input.The simulation results show that the model is high in simulation precision,simple,practical and suitable for air combat tactics simulation.
