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 xflr5.
- - XFOIL is the most popular Open Source & free alternative to xflr5.
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 xflr5.
QBlade is an 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.
