They are not supported products of Pointwise, Inc. Airfoil ToolsĪirfoils can be generated with either sharp or blunt trailing edges. This script provides a way to generate NACA 4-Series airfoil geometries within Pointwise without relying on external coordinate files. If nothing happens, download the GitHub extension for Visual Studio and try again. If nothing happens, download Xcode and try again. If nothing happens, download GitHub Desktop and try again. Polar diagrams for most airfoils generated using Xfoil.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Validation of user added airfoils less rigourous. Latest updates Additional xfoil polars at new Ncrit values with changes to filter polars by Reynolds number and Ncrit Added the 'halo' option to the airfoil plotter to draw a line parallel to the airfoil envelop for wing covering or construction templates. Reynolds number calculator Check the Reynolds number range of your wing or blade so you can select the most suitable polar diagrams. Currently the airfoils are only stored in your browser session and will need to be added when the browser is re-opened NACA 4 digit airfoil generator Generate NACA 4 digit airfoil sections to your own specification and use them in the airfoil comparison and plotter. There are many sources of airfoil data or the sections can be generated using tools. Paste the dat file data into a form and the airfoil will be available to use in the drop down menus. My airfoils Add your own airfoils so they can be used in the tools. Compare lift and drag polar diagrams for a range of Reynolds numbers. The plan can be downloaded or printed full size for better resolution. Airfoil comparison Plots two or more airfoils on the same plan for shape comparison. The camber, thickness can be adjusted and the pitch set to allow for wing angle of attack, wash out or wind turbine blade angle. Airfoil plotter View and plot a full size plan of the airfoil to your chord width.
View the airfoil details page with polar diagrams for a range of Reynolds numbers. Links to the original data source for more information. Download the dat file data in various formats or use the dat file data in the tools. Airfoil search Search for airfoils available on the web or in online databases, filtering by thickness and camber with preview images of the airfoil sections. No content or images on this web site should be reproduced without permission. Your Reynold number range is 50, to 1, Airfoil Tools Tools to search, compare and plot airfoils.
When the search and comparison functions were added I decided it would be better as a stand alone web site and AirfoilTools. The plotter was first published on NACA 4 digit airfoil generator (NACA 2412 AIRFOIL) These applications were first developed as scripts when I wanted to cut ribs and foam cores for some wind turbines I was making.
