Kurzfassung

The paper describes the experimental evidence for the DLR-F11 high lift configuration to be used within the context of the 2nd phase of the AIAA High Lift Prediction Workshop. The model geometry is representative for a wide-body commercial aircraft. For the present purpose a wing/body combination is considered with a continuous slat and flap system in landing setting. Slat and flap are intersecting with the fuselage in order to suppress side edge interference effects and their aerodynamic impact on maximum lift. A CAD model in various degrees of detail has been refurbished, serving as the common geometrical basis for the scheduled CFD investigations. Experimental data of the European project EUROLIFT for low and high Reynolds number conditions have been made available, making use of the same wind tunnel model. The data for low Reynolds numbers have been gathered in the Low Speed Wind Tunnel of Airbus in Bremen, B-LSWT, Germany, while the high Reynolds-number data have been measured in the European Transonic Windtunnel, ETW, under cryogenic conditions. The Reynolds numbers between both datasets differ by an order of magnitude. In addition to force and moment data, which are available from both wind tunnel tests, a comprehensive validation database is available of the tests in the B-LSWT. The experimental data comprise oil flow pictures, transition information by hotfilms and infrared thermography, as well as PIV velocity data in various locations of the F11 configuration for a sample of angles of attack up to and beyond maximum lift. The main features of the experimental evidence are analyzed, comparing pressures and forces for low and high Reynolds number conditions. Examples of the oil flow pictures, transition information, and off-body velocity data are presented and briefly discussed.
