Description
Summary:Unsteady aerodynamic loads may be described in terms of the aerodynamic excitation arising from unsteady separated flows (buffet) or the associated uncoupled structural response (buffeting). Buffeting response measurements arc usually made on nominally rigid or aero-elastically tuned models, with buffeting levels determined from the narrow band response of wing root strain gauges or wing tip mounted accelerometers. In such cases the model structural dynamics are tuned to provide sufficient buffeting response. The original document contains color images.
