【Abstract】 In this paper, the subsonic unsteady aerodynamic performance of a noncoplanar wing-tail combination can be computed on condition that the velocity potential function of unsteady vortex ring is taken as an elementary solution and the method of time history (MTH)is used. That furnishes an effective and perfect computing method for designing a vehicle by analyzing its unsteady aerodynamic characteristics.The method introduced in this paper applies in particular to numerical computation for studying and analyzing the whole course of unsteady dynamic response of various vehicles.Further introduction of the application of this computing method to unsteady dynamic response of an aircraft to atmospheric turbulence, including various discrete gusts and continuous turbulence spectrums, will be given in articles to follow.更多还原
