NACA
NACA Airfoils
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.

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

List of Routines:

NACA4_CAMBERED: (xu,yu), (xl,yl) for a NACA cambered 4digit airfoil.

NACA4_SYMMETRIC evaluates y(x) for a NACA symmetric 4digit 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.
