The interior noise of jet aircraft can compete with luxury cars. Propeller driven aircraft, however, generally suffer from an unpleasantly loud cabin noise. The aerodynamic and acoustic effects of non-axial inflow on wide-chord, advanced high speed propellers are studied by means of a lifting surface theory. Starting from the flow equations for a perturbed, axially subsonic flow, expressions are derived for the pressure and velocity field of a propeller. By using a Green's function representation in separated, cylindrical coordinates the boundary condition at the hub is naturally incorporated.
