Airfoil Tools
Airfoil Tools lets users search among 1,638 airfoils and load airfoil data for analysis.
About Airfoil Tools
Airfoil Tools is a web-based set of tools for searching, comparing and plotting airfoils. It searches 1,638 airfoils and allows filtering by thickness and camber, with preview images and links to original data sources. Users can download dat file data in various formats or use it in the site's tools. The plotter generates full-size SVG plans to a chosen chord width, with adjustable camber, thickness and pitch. The comparison tool overlays two or more airfoils and can plot lift and drag polar diagrams for a range of Reynolds numbers. Additional utilities generate NACA 4- and 5-digit sections and calculate Reynolds number ranges. User-added airfoils can be pasted as dat file data, but they are stored only in the browser session and must be re-added when the browser is reopened. Validation of user-added airfoils is described as less rigorous, and polar diagrams are generated using Xfoil for most airfoils.

Airfoil Tools FAQ
How many airfoils can I search on Airfoil Tools?
The site allows searching 1,638 airfoils, with filtering by thickness and camber and preview images of the airfoil sections.
Are user-added airfoils saved between sessions?
No. Currently, user-added airfoils are stored only in the browser session and must be added again when the browser is re-opened.
Can I print a full-size airfoil plan?
Yes. The SVG plan can be printed out full size or over multiple pages for large sections.
