Hypersonic Aeroelastic Response of Elastic Boundary Panel Based on a Modified Fourier Series Method

Hypersonic Aeroelastic Response of Elastic Boundary Panel Based on a Modified Fourier Series Method

In this paper, an analytical method is proposed to directly obtain the aeroelastic time domain response of the elastic boundary panel. Based on a modified Fourier series method (MFSM), the vibration analysis of elastic boundary panels is carried out, after the dynamics equation of the panel is obtai...
