Abstract

Abstract:

Transonic static aeroelastic analysis has always been a difficult problem in engineering design. In this paper, based on the linear static aeroelastic equation in the modal coordinate system, a new efficient transonic static aeroelastic analysis method based on high precision modal aerodynamics is developed. The method still solves the linear equation,but for the key aerodynamic increments caused by the modal deformation, which can be obtained by the one-way CFD(Computational Fluid Dynamics)/CSD(Computational Structural Dynamics) interaction. With the method, effective fusion of high efficiency linear method and high accuracy CFD/CSD interaction method is realized. To validate the effects of the method, static aeroelastic problems of a small aspect ratio wing with/without control surface and the aileron efficiency of a fighter aircraft are analyzed, and the results of the classical linear method, CFD/CSD interaction method and test flight identification are compared, which show that the method developed has a comprehensive advantage in terms of efficiency, accuracy and robustness, and has high engineering application value.

Key words: aeroelasticity, transonic, structure modes, CFD/CSD interaction, aileron efficiency, test flight identification
