过失速下俯敏捷性及纵向控制效能需求研究

结合飞行安全和作战效能需求,对过失速战斗机的大迎角/过失速迎角下俯敏捷性指标及纵向控制效能需求进行了研究.为了满足飞行品质和过失速敏捷性指标要求,采用非线性动态逆方法设计了某推力矢量飞机快回路和慢回路飞行控制律.在此基础上,根据过失速下俯敏捷性和滚转敏捷性指标要求,对所需的最小俯仰推力矢量偏角进行了计算分析,所得结果对先进战斗机的设计有一定的参考价值.

Research on Pitch down Agility and Pitch Control Requirement at Post Stall

Considering the requirement of flight safety and combat efficiency,the pitch down agility metrics and the longitudinal control requirement for advanced post-stall aircraft at high-angle-of-attack/post-stall was discussed in this paper.In order to meet the request of both flying quality and post-stall agility,a nonlinear dynamic inverse(NDI) method was engaged to design the fast-loop and slow-loop flight control law of a thrust vectoring control aircraft.And then the min deflection of the pitch thrust vector...
