The wind tunnel of the faculty of mechanical engineering at the Unviversität der Bundeswehr München is used for the investigation of two-dimensional airfoil characteristics. The measurement results in the open test section showed a relatively low repeatability and additionally larger deviations from reference data after the application of test section interference corrections. Therefore, the testing procedure is improved and the interference corrections are changed to a method, which represents the actual test situation much better. As a result, the measurements are very repeatable and the corrected airfoil polars match very well with reference data from larger wind tunnels and XFOIL calculations.    «
