The Analysis of Aircraft Maneuver Efficiency within Extend Flight Envelop

Abstract

Using thrust vector must be one of key technique characters for the forth generation fighters especially in condition of High AOA(Angle of attack). The general effectors lost the maneuver efficiency or get poorly, so new type of control law must be found to improve the maneuver efficiency of aircraft within extended flight envelop. The control law should not only overcome those problems but also satisfy requirement of the forth generation aircraft. For those reasons, the Receding Horizon Optimal (RHO) control law is brought out to solve those problems. Simulation results comparison between using the general effectors and using the general effectors with thrust vector all together show: within the extend flight envelop thrust and thrust vector use together can guarantee aircraft following pilot command exactly, the RHO control law can solve those problems perfectly and satisfy the requirement of the forth generation fighter.
