Studies on the Gust Response of a Wing : Part II. Response of a Two-Dimensional Elastic Wing

Abstract

In this report, the responses of an elastic wing to two-dimensional gusts were investigated. The deformations of a two-dimensional elastic wing caused by gust were separated into two types, i.e., the bending mode and the torsional mode. The gusts treated here were the sinusoidal gust and the random gust. In the case of sinusoidal gust, the modes of deformation were obtained both theoretically and experimentally. In the case of random gust, the power spectral functions and the frequency transfer functions were obtained experimentally. The frequency transfer functions obtained by theoretical calculations were also compared with the experimental values.
