The Application of Maximum Likelihood Method to Identify the Flight Polar Curve

in this paper, the basic principle of nonlinear maximum likelihood method to identify the flight polar curve is presented. The simulating and processing results of measured flight test data show that the method can identify smooth nonlinear polar curve and the algorithm is the good convergence property and the uniqueness of the result. Besides, the present method can be popularized to identify the other types of nonlinear curves in the engineering field conveniently.
