Abstract

This paper aims at the problem of inaccurate aerodynamic model of aerial guided bomb in high-altitude rarefied atmosphere. By designing the excitation input and flight data acquisition scheme, the identifiable flight source data are obtained. Then, based on the dynamic equation, the flight source data is converted into the equation output of aerodynamic coefficient. Finally, by minimizing the sum of squares of equation output errors, an aerodynamic parameter identification method based on linear regression is proposed. This method has the characteristics of simple structure, easy implementation and strong engineering feasibility. The method is verified by the flight simulation data of a six degree of freedom nonlinear model of an aerial guided bomb. The results show that this method can accurately identify the corresponding aerodynamic data.

Key words： aerial guided bomb; aerodynamic parameter identification; equation error method; regression analysis
