AN INVESTIGATION ON THE EFFECT OF SECOND-ORDER ADDITIONAL THICKNESS DISTRIBUTIONS TO THE UPPER SURFACE OF AN NACA 64,-212 AIRFOIL

摘要

This report describes a series of low speed airfoil designs based on modifications to the NACA 641-212 airfoil. Designs are based on potential flow theory. This report describes one of a series of airfoil modifications carried out under Contract HAS 2-8599, Application of Multivariate Search Techniques to Optimal Wing Design in Non-Linear Flow Fields. Mr. Raymond Hicks of National Aeronautics and Space Administration's Aeronautical Division, Ames Research Center, served as contract monitor for the present study.
