10/12/2021 - Coordinates for the MH112 and MH120 were incorrect. The coordinates have now been corrected. Thanks to Robbert van den Bosch for catching this.
9/2/2021 - Thanks to Alan Eliasen, a script was written in his programming language Frink to create a single webpage showing plots of all the airfoils (snapshot from 9/2/2021): airfoils.svg - uses SVG graphics (scalable vector graphics) to create the plots
airfoils.html - uses HTML5 Canvas for rendering and may not be displayed in large browser windows or older browsers due to browser limitations
 For more details, check out his script: airfoilPoster.frink6/27/21 - Added the Jochen Günzel JX-GS-04, JX-GS-06, JX-GS-10, JX-GS-15 airfoils -- a family of airfoils for building a complete wing for fast slope racing (F3F). He writes: 'Maybe the most remarkable aspect of these airfoils is their complete artificial design made with an enhanced version of Xoptfoil by Dan Prosser named Xoptfoil-JX (https://github.com/jxjo/Xoptfoil). Target of the design was taking special care of the turbulent situation close to the ground level boundary layer of the wind at a slope.' 
6/27/21 - Updated some of the airfoil file names in the updates section.
6/4/21 - Added Drela airfoils: HT13, HT14, HT21 from http://www.charlesriverrc.org/.

5/31/21 - Added the AS6091, AS6092, AS6093, AS6094, AS6095, AS6096, AS6097, AS6098, and AS6099 thin 'bird-like' airfoils reported ref: Ananda, G.K. and Selig, M.S., 'Design of Bird-Like Airfoils,' AIAA SciTech, 2018 AIAA Aerospace Sciences Meeting, AIAA Paper 2018-0310, Kissimmee, FL, January 2018: here.
5/27/21 - 5/30/21 - Updated zipfile archive in 'Selig' format: coord_seligFmt.zip. This file contains all airfoils (approx 1,600). Removed the previous companion .tar.gz file. Thanks go to Alan Eliasen (https://frinklang.org/) who helped identify some coordinate files needing minor fixes to make the set consistent in format.
9/16/20 - Added this bullet point: From XFOIL documentation verbatim: 'Some Fortran implementations will also choke on airfoil names that begin with T or F. These will be interpreted as logical variables, defeating the name-detection logic. Beginning the name with _T or _F is a workable solution to this 'feature'.' For instance, the FX 76-120 airfoil file begins with 'FX 76-120'. Attempting to analyze this airfoil (file) will create a bogus airfoil shape in XFOIL, e.g. as seen using the XFOIL GDES command after loading the airfoil. Renaming the first line to 'Wortmann FX 76-120' (or '_FX 76-120') resolves the problem.
8/16/20 - Thanks to Koen Stegen for catching a link typo. No change in airfoil coordinate data.
8/8/20 - Many moons ago, Peter Gasparovic provided a smoothed version of the RAF 6 airfoil, which he states is often used on propellers. The airfoil file name is raf6prop_sm.dat, and it is in the updates directory. He noted that he took 'the coordinates for 12% airfoil from NACA TR-259 and smoothed it in LE section.' The points are much higher quality than the original and suitable for analysis in , say, XFOIL.
8/7/20 - Added three new 21% thickness wind turbine airfoils provided by Prof Joseph Saab: SP4621HP, SP4721LA and SP4721BS. He writes: 'We have developed a family of high chord-based Reynolds number airfoils for large size wind turbines, which are theoretically quieter than available profiles. They were developed with a modified BPM TE-noise prediction method we have incorporated into the TU-Berlin QBlade environment for wind turbine development.' The design Re is 7.7 million (with a working range from 4 to 9 million). The transition points were set at 5% for the upper surface and 10% for the lower surface. The SP4721BS is a bird-saving derivative with a calibrated TE thickness to induce a tonal noise to alert birds of the presence of the wind turbine and should be used in limited-span sections and bird migration affected areas. The new Saab-Pimenta airfoils SP4621HP, SP4721LA and SP4721BS are in the updates directory. The airfoils are described in the thesis from the USP (Sao Paulo State University) public archives here. For complete details, see the Poli-Wind research group site at https://sites.usp.br/poli-wind/.
8/6/20 - Added new contributions from Francisco Espenica. The additions are the 5 marine turbine airfoils: IST-MT1-12.dat, IST-MT1-15.dat, IST-MT1-18.dat, IST-MT1-21.dat, and IST-MT1-24.dat. He writes: 'These airfoils result from an optimization effort aimed at increasing hydrodynamic performance while maintaining a low suction peak. The source work consists of my Master Thesis, which is currently in the process of being published.' The airfoils naming key is: IST - Instituto Superior Técnico, MT1 - Marine Turbine, and XX - 2 digits defining the airfoil maximum thickness. The airfoils have been added to the updates directory.
3/7/20 - Added mention of corrected NACA coordinates from Theory of Airfoil Sections (Abbott and von Doenhoff) courtesy of Ralph Carmichael, PDAS: https://www.pdas.com/avd.html.
 3/3/20 - NASA TP 1391, RC12-64c, coordinate error suspected.
 3/2/20 - Fixed a point on the NACA 65(1)-212 (a=0.6). The file name is naca651212a06.dat. Deleted the airfoil CAD folder. The zipfiles (.zip and .tar.gz) have not yet been updated.
 10/9/18 - Added the vertical axis wind turbine (VAWT) airfoils MI-VAWT1 and MI-STRUT1 airfoils from Dr. Mazharul Islam. He designed them during his doctoral studies at the University of Windsor, Canada. For coordinates, see the updates directory.
 5/6/17 - Replaced MH 46 airfoil file (thanks to Lincoln Ross). Fixes thickness ratio. Now it is 11.39% per Martin Hepperle website.
 12/30/16 - Removed M8 and M9 because the coordinates were found to be wrong.
 11/25/16 - Added NASA Armstrong Prandtl-D airfoils from NASA TP-2016-2190972: Al Bowers, et al., 'On Wings of the Minimum Induced Drag: Spanload Implications for Aircraft and Birds.' See the updates directory.
 5/13/16 - Added a link to Python scripts for converting .dat text files (this type) to SVG format files: https://github.com/jdcasey/airfoil-utils. Thanks for John Casey for this github repo.
 4/8/16 - Added McDonnell Douglas (MDA) 30P/30N multielement airfoil coordinates and rigging info for the coordinates with labels: #Slat, # Main, and # Flap. See the updates directory: file 30P-30N.dat. Thanks to Brent Pomeroy for this addition. 
 1/25/13 - Added Barnaby Wainfan's BW 05 02 09 found online at www.rcsoaringdigest.com. 
12/20/12 - Added the Supermarine 371-I (root) and 371-II (tip) airfoils thanks the contribution by Dr. Neil Fomison. 
12/20/12 - Added the S4094, S4095, and S4096 airfoils that were designed for and used on the E-flite UMX ASK-21 scale RC sailplane. The root airfoil is the S4094 and it blends into the S4095 and S4096 toward the tip. The design Reynolds number is between 15,000 and 20,000. The airfoils include a blunt trailing edge to accommodate injected molded manufacturing considerations. 
12/20/12 - Added the LRN 1015 airfoil tested by NASA and sent in by Sebastian Maciejewski. Thank you! This airfoil is used on the Northrop Grumman RQ-4 Global Hawk, and it's hard to believe that it was only added now. It's been around since 1991 (Ref. NASA TM 102840). 
5/13/12 - Thanks to Pritesh Mody for correcting the SC(2)-20412 airfoil coordinate @ 0.73 on lower surface. The coordinates files have been updated, but (heads-up) these corrections have not been migrated to the zipfile download or AutoCAD .dwg files.

4/1/10 - Thanks to Christoph Hiemcke for catching a missing sign on the last few lower-surface trailing-edge points of the FX 67-K-170/17. The coordinates are fixed in the coordinate files here ~/coord/ and ~/coord_seligFmt/ but not elsewhere (yet).
9/13/09 - Major website overhaul and some fixes. Still a work in progress.
2/19/08 - Added the TSAGI R-3A submitted by Zverkov Ilya. He writes that: it is a general aviation airfoil. It has wide spread in Russia for ultra light aircrafts. The first reference is Krasilshikov P.P. 'Airfoil characteristics atlas', TSAGI, Moscow, 1940. Original airfoil has 15% thickness. This one is 12% thick.
5/15/07 - Added a Rhinoceros (3D CAD software) airfoil suite from Rick Loheed.
11/29/06 - Added NACA 65(3)-618.dat provided by Bob Kuykendall.

 3/16/04 - Added these notes for Microsoft IE users.
 Missing Links: Some people who use Microsoft IE have reported that the links below are not displayed. This is a Microsoft browser problem. If anyone has a solution, let me know.
 Resized images: The new version of IE by default will automatically resize graphics images to fit your screen. The plots of the airfoils below are large and will likely be resized. In the IE Tools -> Internet Options -> Advanced area, this resize 'feature' can be disabled if desired. Search for 'Enable automatic image resizing' under the Multimedia section heading.
 12/12/02 - Big Update. Added several new airfoils from many sources, and the version number was incremented to 2. There are now 1550 airfoils in the database. Dave Lednicer was able to track down a new Liebeck airfoil for the listing. Also, Lawrence Hur (UIUC undergrad) gathered up 250 or so new airfoils! I've also added many airfoils from Mark Drela and Martin Hepperle. The coordinates from Martin Hepperle might not match perfectly with those from before because he regenerated the designs to higher precision. Hopefully, I have not forgotten anyone!
 12/12/00 - Added link to Prof Mark Drela's public release of XFOIL for airfoil design and analysis.
 9/15/00 - Replaced the image on the ads page. The old one below was retired after several years of service.
 NSU2D Navier-Stokes CFD calculation courtesy of C.K. Song (B.S., UIUC/AE).
 4/9/00 - Added MH64 to the update dir.
 3/25/00 - Added the EH 2.0/7.0 and EH 1.0/7.0 to the update dir.
 9/26/99 - Added the faq_ads.html FAQ regarding airfoil performance data.
 3/26/99 - Added the NACA 64(2)-415 to the update dir.
 3/5/99 - Decided to move the updates to one single directory. Added to the updates directory: Mark Drela's MRC 16 and MRC 20 used on the Decavitor human powered hydrofoil, and also the E591.
 8/23/98 - The AH21 was incorrectly attributed to Althaus. The AH21 is an Andrew Hollom airfoil designed as an improvement over the RG15. The original AH21 airfoil was 9%, then a 7% version was designed. Both versions are not included in the main listing. The archives still contain the incorrect reference.
 8/20/98 - Another update to Lednicer's NACA.EXE code.
 8/6/98 - Posted an update to Dave Register's airfoil plotting program.
 7/15/98 - Added some more links under 'Other Airfoil Data and Information Sites'.
 8/28/97 - Opus ftp site for airfoil coordinates (UIUC Airfoil Data Site) is back online.
 8/20/97 - Added more airfoils: cootie.dat drgnfly.dat, du861372.dat, fx711530.dat, lds2.dat, naca1.dat, nlf0115_lfmt.dat, nlf1015_lfmt.dat, pfcm.dat, sc20010.dat, sc20012.dat, sc20402.dat, sc20403.dat, sc20404.dat, sc20406.dat, sc20410.dat, sc20412.dat, sc20414.dat, sc20503.dat, sc20518.dat, sc20606.dat, sc20610.dat, sc20612.dat, sc20614.dat, sc20706.dat, sc20710.dat, sc20712.dat, sc20714.dat, sc21006.dat, sc21010.dat, sg6040.dat, sg6041.dat, sg6042.dat, sg6043.dat, sg6050.dat, sg6051.dat.
 4/3/97 - More about the LS(1)-0413 [GA(W)-2]: The NASA LS(1)-0413 listed are the original coordinates from the report NASA TM X-74018, which also includes original coordinates for the LS(1)-0413MOD. The report NASA TM X-72697, which covers the GA(W)-2 tunnel tests, only includes the coordinates measured off the model. Finally, the LS(1)-0413 coordinates listed in NASA-CR-145139 in August 1976 appear to be wrong.

 3/6/97 - A viewer found a bug: 'The airfoil data listed for the LS(1)-0413 [GA(W)-2] differs from that published in NASA-CR-145139 in August 1976. The differences are greatest near the leading and trailing edges.' The file has not yet been corrected. See ls0413.html
 Added *.zip archives of 12-15-96 database.
5'6 In Cm 1/22/97 - A correction - The Wortmann FX 71-L-150/30 airfoil file (fx71l150.dat) was actually a duplicate of the Wortmann FX 71-L-150/20 airfoil (fx711520.dat). The gif plot for the errant Wortmann FX 71-L-150/30 was removed.
 11/13/96 A correction - The airfoil that was identified as the MS(1)-0413 in the database should be the MS(1)-0313 instead. This change has been made. The gif plot has not been change as of this date.
 11/9/96 - Posted some new airfoils to the Airfoil Data Site: bw3.dat, davis_corrected.dat, e231.dat, e476.dat, e477.dat, e478.dat, eh0009.dat, eh1090.dat, eh1590.dat, eh2010.dat, eh2012.dat, eh2510.dat, eh3012.dat, griffith30SymSuction.dat, s8038.dat (designed for David Ribbe's winning scale R/C MiG 15flickr pictures), s8055.dat.
