QBlade is described as 'Open source wind turbine calculation software, which integrates XFOIL/XFLR5 functionality, and allows the user to rapidly design custom airfoils and compute their performance polars and integrate into rotor design and simulation' and is an app. There are four alternatives to QBlade for Windows and Linux. The best QBlade alternative is XFOIL, which is both free and Open Source. Other great apps like QBlade are javafoil, Profili 2 and xflr5.
XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils. Given the coordinates specifying the shape of a 2D airfoil, Reynolds and Mach numbers, XFOIL can calculate the pressure distribution on the airfoil and hence lift and drag characteristics.
XFOIL is the most popular Windows & Linux alternative to QBlade.
XFOIL is the most popular Open Source & free alternative to QBlade.
JavaFoil is a new implementation of my previous CalcFoil program. Like SimProp, CalcFoil was written solely for my web pages using the "C" language.
Profili is a software developed to help the 'do it yourself' modelers. This new version can assist you in: Searching for the right airfoil for your application Creating new airfoils Analyzing the airfoil aerodynamic and more.
Profili 2 is the most popular commercial alternative to QBlade.
XFLR5 is an analysis tool for airfoils, wings and planes operating at low Reynolds Numbers. It includes:
