A Direct Time History Study of the Response of an Airplane to Nonstationary Turbulence.
Abstract
Previous nonstationary turbulence studies are discussed. A novel way for evaluating the impulse response function for gust encounter is derived, which automatically takes into account nonsteady lift and gust penetration effects. Various nonstationary gust fields, having spectral content and level exceedance behavior representative of atmospheric turbulence, are then synthesized; airplane response is evaluated in explicit time history form so that all transient effects are included. The generalized load exceedance curves derived from the time histories are compared with the results that are indicated by an existing technique which derives nonstationary results on the basis of local stationary encounters.
