This paper presents the extension of the prescribed velocity method, known as the Split Velocity Method, for the purposes of modelling flexible aircraft gust responses. This is achieved by performing aeroelastic simulations using the computational fluid dynamics flow solver DLR-TAU coupled with a modal structural solver. This method is demonstrated by computing the response of a wide-body aircraft to a series of 1-cosine gusts. The results are compared to an existing prescribed velocity method, the Field Velocity Method. It is shown that the Field Velocity Method is a simplification of the Split Velocity Method and this results in noticeable differences in the solution for short wavelength gusts, where the velocity gradients are greatest
