NACA Airfoils {#naca-naca-airfoils align=”center”}
=============
NACA is a C++ library which can take the parameters of certain NACA
airfoils and return the coordinates of a sequence of points that outline
the wing shape. The data can be displayed with gnuplot.

NACA is available in a C version and
a C++ version and a FORTRAN77
version and a FORTRAN90
version and a MATLAB
version.
GNUPLOT, C++ programs which
illustrate how a program can write data and command files so that
gnuplot can create plots of the program results.

airfoil.
- NACA4_SYMMETRIC evaluates y(x) for a NACA symmetric 4-digit
airfoil.
- R8MAT_WRITE writes an R8MAT file.
- R8VEC_LINSPACE creates a vector of linearly spaced values.
- R8VEC_MAX returns the maximum value in an R8VEC.
- R8VEC_MIN returns the minimum value of an R8VEC.
- TIMESTAMP prints the current YMDHMS date as a time stamp.
