HN-419
The Venkataraman airfoil fit was presented in AIAA-95-1875 by P. Venkataraman of the Rochester Institute of Technology.
The airfoil geometry is obtained through four Bezier curves, two for the upper surface (forward and aft), and two for the lower surface (forward and aft). This ease of construction makes it suitable for ease of use in CAD systems, and in airfoil shape optimization.
