Summary:

A series of tests has been conducted in the variable-density wind tunnel on several airfoils of different sizes and sections to determine the effect of tunnel-wall interference and to determine the effect of tunnel-wall interference and to determine a correction which can be applied to reduce the error caused thereby. The use of several empirical corrections was attempted with little success. The Prandtl theoretical correction gives the best results and its use is recommended for correcting closed wind tunnel results to conditions of free air.
