摘要
舰载机在航母上降落时,舰尾气流的扰动是影响着舰精度的主要因素。以变后掠翼舰载机为研究对象,根据其操纵特性,设计了引入侧偏速率反馈的抗侧风飞控系统控制律,优化自动着舰引导系统轨迹控制器系统参数,并根据系统结构配置构建仿真系统。通过对比侧偏速率反馈引入前后的系统性能表明,引入侧偏速率反馈明显降低了舰尾流对变后掠翼舰载机的影响,提高了着舰安全性。
Wind and atmosphere turbulence have deep influence on landing precision,when the aircraft is preparing to land on the carrier.The variable swept wing carrier-aircraft was regarded as research object,and the flight control law introduced side velocity feedback was developed with its handling feature.Trajectory control parameter of the automatic carrier landing system was optimized.The simulation system was constructed for verifying and evaluating the performance of this system.The simulation result indicates that the system limits the influence of the turbulence on variable swept wing aircraft,and has a great meaning for improving the landing performance and security.
