The Influence of Non-linear Longitudinal Aerodynamic Characteristics on the Power Spectral Response of Aircraft to Atmospheric Turbulence
Published online by Cambridge University Press: 07 June 2016
Summary
The power spectral technique has been extended to show the effect of aerodynamic non-linearities on the normal acceleration response of a rigid aircraft in the cruise configuration. Non-linearities in the normal force and pitching moment variations with incidence have been considered. The resulting changes from the linear root-mean-square values of normal acceleration were only 3 to 5½% for a root-mean-square vertical gust velocity of 20 m/s.
