Correction Methods of Aerodynamic Force and Moment Coefficients Based on the Identification Data

In this paper, three methods are proposed to correct the aerodynamic parameter sheet based on the identification data in typical flight states, including the optimized model fitting correction method based on L2 regularized least squares method, the deviation model fitting correction method and the neural network based fitting correction method. The correction results of these three methods are calculated with longitudinal aerodynamic data of the common aero vehicle, which verify the validity of the methods, and the comparison between them is also illustrated.
