A Method of Static Aeroelastic Analysis Based on Three Dimension Aerodynamic Force and Aeroelastic Correction for Hypersonic Vehicles

摘要

Under the hypersonic condition, considering the complexity of the coupling between the aerodynamic and the structural, and considering the compromise between the analytical precision and the analytical efficiency, this paper develops an aerodynamic analysis method based on the piston theory considering the elasticity correction-a aerodynamic engineering method which can be applied to coupling with arbitrary three-dimensional structure, so as to rapidly complete the static aeroelastic analysis of hypersonic aircraft. In this paper, a hypersonic wing is taken as an example, and the rigid aerodynamic force is compared with the literature, which proves the rationality of the method. The results compared with those calculated by CFD / CSD coupled numerical method are close.which shows that the elasticity correction method of this paper has engineering applicability.
