How do you find an airfoil?
Tools to search, compare and plot airfoils. Search for airfoils available on the web or in online databases, filtering by thickness and camber with preview images of the airfoil sections. Download the dat file data in various formats or use the dat file data in the tools.

What does mod mean in airfoil designations?
On designations: many of the airfoils listed here have “mod” at the end of their designation. Typically, this means that either the camber line has been modified, the leading edge contour has been modified or that the trailing edge thickness has been changed. Some common airfoil name prefixes and their designers are:
What types of airfoils are addressed in the UIUC data site?
Besides conventionally configured aircraft, canard configured aircraft, tandem wing aircraft, three-surface aircraft, helicopters, tilt rotors and autogyros are addressed. Many of the airfoils listed below can be found at the companion site: UIUC Airfoil Data Site .
What is the maximum thickness of an airfoil?
•Airfoil has maximum thickness of 15% of chord (0.15c) •Camber of 2%(0.02c) located 40% back from airfoil leading edge (0.4c) NACA 2415 11 NACA Four-Digit Series •Earliest NACA airfoils were designated as four-digit series. •The thickness distribution is given as : •where, t = maximum thickness as fraction of chord. •The leading radius is : r
How is the NACA airfoil section calculated?
The NACA airfoil section is created from a camber line and a thickness distribution plotted perpendicular to the camber line. The equation for the camber line is split into sections either side of the point of maximum camber position (P). In order to calculate the position of the final airfoil envelope later the gradient
What is the chord width of a 20% airfoil?
At the trailing edge (x=1) there is a finite thickness of 0.0021 chord width for a 20% airfoil. If a closed trailing edge is required the value of a4 can be adjusted. The value of yt is a half thickness and needs to be applied both sides of the camber line.
