Effects of Aerodynamic Lags on Aircraft Responses,
Abstract
Results of a theoretical study on the effects of unsteady aerodynamics on symmetric aircraft responses due to elevator and vertical turbulence inputs, are presented. Several linear models were developed to describe unsteady lift and downwash and delays due to horizontal tail length. Results for three example aircraft types show that calculated normal acceleration levels due to turbulence are very 'little affected by including unsteady wing lift and downwash. However, there appears to be a noticable influence on plunging acceleration and pitch rate response to elevator or vertical turbulence inputs.
