Aerodynamic Characteristics of Four NACA Airfoil Sections Designed for Helicopter Rotor Blades
Description:
"The purpose of the present work is to extend the previous investigation and to derive additional airfoil sections designed to minimize the undesirable characteristics of the previously tested airfoils. The tests of these additional airfoils were made in the Langley two-dimensional low-turbulence tunnel (LTT)" (p. 2).
