A Computerized Procedure to Obtain the Coordinates and Section Characteristics of NACA Designated Airfoils

The report describes the technical and analytical aspects of a computer program written to give airfoil coordinates, incompressible inviscid section characteristics and two-dimensional drag-rise Mach numbers for a large number of NACA airfoils from a simple one card input. The computer program is a...

Zusammenfassung:	The report describes the technical and analytical aspects of a computer program written to give airfoil coordinates, incompressible inviscid section characteristics and two-dimensional drag-rise Mach numbers for a large number of NACA airfoils from a simple one card input. The computer program is a combination of two separate programs. One program gives the airfoil surface coordinates with only the NACA airfoil designation as input, and the other program uses the surface coordinates to predict incompressible, inviscid pressure distribution from which the section characteristics and drag-rise Mach number are determined. The capabilities and accuracies of the computer program are described.
