The main objective of this paper is to present a methodology to correct the air loads computed with traditional potential flow models by means of linearised frequency domain analysis. The correction will be compared with the reference accurate steady and unsteady aeroelastic calculations performed with an OpenFSI methodology which strongly couples the structural solver MSC Nastran and the CFD code DLR TAU. This framework has demonstrated the capability to perform static and gust calculations for the FFAST wing, which is representative of a modern civil transport wing. An updated version of the framework will allow rigid body modes of heave and pitch to be included in the analysis. The linearised frequency domain solver has shown higher computational performance compared to unsteady time accurate simulation, hence will allow a reduction in the time necessary to compute the necessary corrections.
