The aerodynamic characteristics of three tapered airfoils tested in the variable density wind tunnel

Raymond F. Anderson
Feb 1931

This report contains the lift, drag, and moment characteristics of tapered Clark Y, Gottingen 393, and USA 45 airfoils as obtained from tests made in the Variable Density Wind Tunnel of the NACA. The results are given at both low and high Reynolds Numbers to show scale effect and to provide data for use in airplane design.
