Shamim Mohamed of Plotfoil fame created a Perl script to convert the Lednicer file format to the Selig format. The more recent plots were generated using a modified version of his Matlab code.

Thanks go to Mark Barton for creating the airfoil plots in gif format for the Version His simple Matlab code for reading the various formats and plotting the airfoils is listed here.

History and Credits First, to those people not listed here who have offered useful information to help build and improve the dataset, thank you! Some details are listed in the update history. First, in addition to these below links, there are more links included with the airfoil listing page.Īirfoil Format For reference, the original airfoils in the list and new ones added by Selig are in an x,y format starting from trailing edge, along the upper surface to the leading edge and back around the lower surface to trailing edge e.Īirfoil Contributions If you would like to contribute airfoils to this site, please email them to m-selig illinois. Updates to the list will occur infrequently and in batches. Those contributions thought to be of general interest will be added. Typically, this description will be reduced to a few words in the database. Please include a description of the airfoil and also identify the source. If you would like to contribute airfoils to this site, please email them to m-selig illinois. So far, no multielement airfoils are included in the database. Some of the airfoils listed do not close at the trailing edge, i. Lednicer's contributions are upper surface points leading edge to trailing edge and then lower surface leading edge to trailing edge e. For reference, the original airfoils in the list and new ones added by Selig are in an x,y format starting from trailing edge, along the upper surface to the leading edge and back around the lower surface to trailing edge e. You can browse the directory, but it is suggested that you use your web-browser "find" button to search for keywords. This addition brought the total number of airfoils to over Since this time, the number of airfoils has expanded to include overand more will be added as they become available.Ĭurrently, the airfoils are listed in alphabetical order by the file name, which most often is the airfoil name or close. Originally the site included mostly low Reynolds number airfoils aboutbut in December the site was greatly expanded when David Lednicer of Analytical Methods, Inc.
The UIUC Airfoil Coordinates Database includes the airfoils, and they cover a wide range of applications from low Reynolds number airfoils for UAVs and model aircraft to jet transports and wind turbines.
