windows default iconQBlade Publisher's description

is an open source wind turbine calculation software, distributed under the GPL.

is an open source wind turbine calculation software, distributed under the GPL. The software is seamlessly integrated into XFOIL, an airfoil design and analysis tool. The motivation for this was to create a one solution software for the design and aerodynamical computation of wind turbine blades. The integration in XFOIL allows for the user to rapidly design custom airfoils and compute their polars, extrapolate the polar data to a range of 360°, and directly integrate them into a wind turbine rotor-simulation. This skips the step of exporting and importing foil and geometry data between different codes, and the troubles associated with that. At the same time the integration of QBlade into XFOIL’s sophisticated GUI (XFLR5) makes this software accessible to many more interested people than the usual command line interface software tools. The software is especially adequate for teaching, as it provides a ’hands on’ feeling for HAWT rotor design and shows all the fundamental relationships and concepts between twist, chord, foils, turbine control and type and the power and load curves in an easy and intuitive way. QBlade also includes post processing of conducted rotor simulations and gives deep insight into all relevant blade and ro tor variables for verification, to compare different rotor configurations, or even to study the numerical algorithm (Blade Element Momentum Theory) and the dependency’s among the aerodynamic variables themselves. In addition to that ,the resulting software is a very flexible and user-friendly platform for wind turbine blade design that can also act as a modular system for future implementations that can exploit the possibilities that a combination of manual and parametric airfoil design and analysis coupled with a blade design and simulation tool offers. The functionality of QBlade includes the following


Extrapolation of XFOIL generated or imported polar data to 360В° AoA
Blade design and optimization, including 3D visualization, using XFOIL generated or imported profiles
Turbine definition (rotor blade, turbine control, generator type, losses...)
Computation of rotor performance over lambda (tip speed ratio) range
Computation of turbine performance over wind speed range
Annual yield computation with WEIBULL distribution
Manual selection of BEM correction algorithms
Manual selection of all simulation parameters
Data browsing and visualization as post processing
Export functionality for all created simulation data
Blade geometry export functionality
Storing of projects, rotors, turbines and simulations in a runtime database
