Abstract

This paper presents a semi-experimental method which can be used to predict the gust response of a wind tunnel model. The method incorporates transfer functions of the wind tunnel model – in this case a flexible forward swept wing – which are obtained using sweep excitations with a gust generator. The prediction results are then compared with those resulting from experimental measurements and numerical simulations. The observed quantities comprise accelerations and loads data. In the ideal case, the advantage of this semi-experimental prediction of the wing’s response to gusts lies mainly in the reduction of wind tunnel time. Instead of testing each gust profile at each frequency, a measurement of several sweep excitations would suffice.
