Abstract
It is important for flight envelop assessment in the presence of control surface damage of aircraft, which can offer information to pilot and protection control in order to improve the reliability. Considered dynamic characteristic of the wing damage, a method of dynamic flight envelop assessment was proposed. According to control surface damage could cause the aerodynamic parameter change, the damage modeling was built. Based on the least square method, the aerodynamic parameters and failure diagnosis were achieved by online. The flight envelop was assessed accurately based on identification and operating trim points. The simulation results show the effectiveness of the proposed method.
