A method for constructing reduced order models of an aerofoil subject to gusts is presented. The method is based on subspace system identification in the frequency domain in order to obtain a model which retains the dynamic information of the original system, while having a comparatively smaller dimension. The gust is prescribed through the domain using the split velocity method to obtain the system frequency response. This is used to find the state matrices of the reduced system. By prescribing a series of 1-cosine gusts, it is shown that the reduced system obtained agrees well with the original system.
