摘要
分析了低动压的背面(backside)着舰工作状态下飞行员仅控制飞机姿态无法控制飞行轨迹角的物理原因。研究了低动压的背面着舰工作状态下使用背面控制策略问题,即以推力来控制轨迹,以飞行姿态来控制迎角。设计了背面技术和前面(frontside)技术控制律,并以A-7E舰载机为例进行了仿真验证。最后对背面着舰工作状态下的背面技术和前面技术进行了比较,分析了海军飞机使用背面技术着舰的原因。
This paper analyzes the physical reasons of that a pilot can not control flight path angle only by controlling aircraft attitude in backside carrier landing situation of low dynamic pressure. Next, backside control strategy is investigated which is a pilot controlling flight path angle by thrust and controlling angle of attack by aircraft attitude. Backside control strategy and frontside control strategy are designed and numerical simulation is made for an A-7E carrier aircraft. Last, backside control strategy and frontside control strategy are compared in backside carrier landing situation of low dynamic pressure with analyzing the reason of navy aircraft using backside control strategy in carrier landing.
