Kurzfassung
The transition prediction capability of two different semi/empirical methods originating from fixed wing applications is studied for steady, rotary wing application. This includes the AHD method, used with approximated boundary layer data, as well as the Drela eN envelope method, based on integral boundary layer parameters. The methods have been implemented in the DLR's structured flow solver FLOWer. A two-dimensional test case (Somers airfoil) and three-dimensional rotor test case at hover (DLR Bo 105 flight test ) serve to validate the computed transition locations.
