In this report, the gust responses of a threedimensional elastic wing are investigated theoretically and experimentally, where the two kinds of gust, sinusoidal gust and random gust, are treated. It is assumed here that the deformation of an elastic wing is generated by bending moment and torsional moment which act on a wing independently.
First, for the responses to the sinusoidal gust, the modes of deformation are calculated applying the modes of natural oscillation of a cantilever beam. The results of calculation agree well with the experimental values.
Next, the frequency transfer functions of deformations by bending moment and torsional moment are obtained for the random gust responses. In this case, the phase difference of the gust along the wing span is taken into consideration. The calculated results agree well with the experimental results.
