Based on the wind tunnel test data of a transport aircraft with ice and the analysis of icing lift characteristics, it is concluded that icing has little effect on the lift coefficient in the small angle of attack (AOA) range. An online principal component estimation algorithm of lift coefficient polynomial based on prior knowledge enhancement was designed to overcome the ill-conditioned problem of data matrix due to insufficient excitation and collinearity between regression variables. The maximum lift coefficient and stall AOA were estimated by using the good linear relationship between the slope variation of the lift curve and the maximum lift coefficient after icing. Compared with traditional methods, the designed method has significant advantages such as high maturity, good real-time performance, and no need for active excitation. Simulation results show that the estimation accuracy can meet the requirements of AOA protection, and the designed method has good engineering application prospects.
