Abstract

This paper highlights the results obtained by coupling the aeromechanic tool HOST with the DLR CFD solver FLOWer within the framework of the EU-Project GOAHEAD. The process was applied to predict the flow around the GOAHEAD configuration in forward flight at Mach number of 0.204 and fuselage pitch angle of -2.5o. Comparisons of the CFD results with experimental measurements revealed very good agreement for main rotor pressure and the front part of the fuselage. Main rotor power could be predicted with an accuracy of 0.25%.
