Experimental Investigations of Buffet Excitation Forces on a Low Aspect Ratio Trapezoidal Half Wing in Incompressible Flow.

Abstract

The paper addresses the problem of determining the steady and unsteady airloads on swept wings of low aspect ratios at high incidences. Despite great progress in the field of computational fluid dynamics, this problem is not yet accessible to computer- supported methods, at least with respect to unsteady airloads. First, the information will be discussed which is necessary for buffeting prediction. The reason for performing pressure measurements are outlined. A brief description of the test set-up and instrumentation is given.
