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