A blade element momentum code (BEM) has been integrated into the graphical user interface (GUI) XFLR5 of the panel code XFOIL. The resulting software, QBlade, features various correction algorithms, such as the Prandtl tip and hub loss correction, Shens new tip and hub loss correction and Snels correction for 3D crossflow effects. An additional module for the extrapolation of polars to a range of 360° is included in the new software. Furthermore various algorithms, to optimize chord and twist distribution are provided to assist the blade design process. For a validation a simulation has been compared to the results of the software WT_Perf and to experimental data.
