In this paper, we briefly introduce some recent achievements of the author in the calculation of the unsteady dynamic response of aircraft to continuous atmospheric turbulence power spectrum.In this paper, we first introduce the unsteady lift plane aerodynamic technology into the calculation of aircraft response to turbulence spectra The numerical calculation method of the aircraft response spectrum and its statistical properties is established. The calculation shows that it is necessary to include the unsteady aerodynamic effect. By using the method described in this paper, two hypothetical prototypes are evaluated and applied, Assessment comments.The method described in this article can be used as anti-turbulence characteristics of aircraft design, analysis or assessment tools for aircraft design practice.
