舰载机/发动机一体化控制着舰复飞动态特性研究

Dynamic characteristics of landing and reflying controlled by carrier aircraft/engine integration

为提高舰载机的复飞成功率和生存率,基于发动机动态模型和舰载机气动模型,以舰载机复飞过程为任务剖面,依据能量法建立了能够准确表达舰载机动态特性的飞/发一体化控制模型。结合舰载机复飞时发动机使用特点,给出了发动机供油规律和控制规律。基于飞/发一体化控制模型,得到了舰载机复飞时着舰重力、甲板长度和甲板风速等参数的关系,为保证舰载机成功复飞提供了参考。

To improve reflying success ratio and survivability of carrier aircraft, based on the dynamic model of the engine and the aerodynamic model of carrier aircraft, and taking the landing and reflying process as the mission profile, an integrated aircraft/engine control model that can accurately describe the dynamic characteristics of carrier aircraft was established according to the energy method. According to the characteristics of the engine of the carrier aircraft in reflying, the rules of the engine fuel supply and control were given. Based on the aircraft/engine control model, the relations of landing weight, deck slippage length and deck wind speed are obtained, which provide reference for the successful escape of carrier aircraft.
