The Aerodynamic Characteristics of Three Tapered Airfoils Tested in the Variable Density Wind Tunnel


Book Description

This report contains the lift, drag, and moment characteristics of tapered Clark Y, Gottingen 398, and U.S.A. 45 airfoils as obtained from tests made in the Variable Density Wind Tunnel. The results are given at both low and high Reynolds numbers to show scale effect and to provide data for use in airplane design.




Tests in the Variable Density Wind Tunnel to Investigate the Effects of Scale and Turbulence on Airfoil Characteristics


Book Description

The effects of scale and turbulence on the lift and drag of five airfoils, the N.A.C.A. 0006 , the N.A.C.A. 0021, the Clark Y, The U.S.A 35-A, and the U.S.N. P.S.6, hve been investigated in the Variable Density Wind Tunnel. Tests were made over a wide scale for only two different conditions of turbulence.
