Abstract

At present, the dynamic modeling methods of elastic aircraft mainly include two kinds: mean axis method and quasi-axis method. The two methods have their own advantages and disadvantages, and there are few articles on the comparison of the two methods. In this paper, based on the Lagrangian equation of energy theory, the modeling methods of the mean axis system and the quasi-axis system are derived, and the elastic models obtained from the quasi-coordinate system and the mean axis system are compared and analyzed. The correctness of the hypotheses is verified by numerical calculation according to the hypothetical conditions, which lays a solid foundation for the further study of aeroelastic modeling.
