Abstract
The flow field around the isolated HART II fuselage is computed by a computational fluid dynamics code. Velocities normal to the rotor rotational plane are extracted in a volume around the rotor as a data basis. A simple semi-empirical physics-based analytical formulation of the induced velocities is developed for use in comprehensive rotor codes. This model allows the computation of fuselage-rotor interferences on the rotor blade element level. It also allows the prediction of the rotor wake geometry deformation due to the presence of the fuselage in both prescribed wake and freewake codes. Its impact on rotor thrust, power and trim is evaluated analytically using blade element momentum theory and by DLR's comprehensive rotor code.
