Four-digit series. The NACA four-digit wing sections define the profile by: For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord....

**NACA airfoil WikiVisually**

We were given an outlined code in our engineering class for a 4 digit airfoil. I have input all equations and the program runs, however it doesn't seem right.... The naming convention of NACA 6-series of airfoils is a combination of the location of maximum thickness, the type of mean line used to generate the chamber line, and the thickness ratio. A NACA 63-415 will have its maximum thickness at approximately 30 percent of chord, the design lift coefficient is 0.4, and the airfoil is 15 percent thick. NACA 4 and 5 digit NACA 6 and 7 Series

[edit] Equation for a symmetrical 4-digit NACA airfoil Plot of a NACA 0015 foil. The first digit. p is the location of maximum camber as a fraction of the chord (10 p is the second digit in the NACA xxxx description). gives the designed coefficient of lift (CL). give p. how to make essiac tea for dogs The older, 4-digit series simply used the mean of a collection of successful early airfoils. I have always used a collection of Fortran subroutines to generate the contour, and it uses tabulated data and splines to generate the shape.

First, t should be 0.12 not 12. Second, to make a smoother plot, increase the sample points. It is also a good idea to use vectorize method in numpy: how to read online articles National Advisory Committee for Aeronautics airfoils. During the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil — a four digit number that represented the airfoil section's critical geometric properties.

The German article has good diagrams which would just need the captions translated. --pfctdayelise 14:25, 2 August 2008 (UTC) Equation for a symmetrical 4-digit NACA airfoil. The third coefficient, 0.3537, seems to be wrong.

- A Description of the NACA 4-Digit System. The National Advisory Committee for Aeronautics (NACA), NASA's predecessor, used a four digit numbering system to describe a large number of airfoil sections.
- Equation for a cambered 4-digit NACA airfoil Plot of a NACA 2312 foil, generated from formula The simplest asymmetric foils are the NACA 4 digit series foils, which use the same formula as that used to generate the 00xx symmetric foils, but with the line of mean camber bent.
