Keywords: hypersonic, time-domain, aeroelasticitynon-linearity

Various engineering methods for hypersonic aerodynamic loads are combined and extended to solve the unsteady pressure. By numerical method, the hypersonic aeroelasticity with aerodynamic non-linearity is simulated in time domain. Some typical non-linear phenomena have been found.
