A Preliminary Study of the Hypersonic Flow of Helium-Air Mixtures

Abstract

Theoretical predictions were developed to describe the effects of the addition of varying amounts of helium to the flow of air in a hypersonic wind tunnel. Much greater over-all flexibility in operational Mach number and Reynolds number was demonstrated. Preliminary experimental studies have, in part, substantiated the theoretical predictions. Various possibilities for the use of a helium-air mixture as a wind tunnel testing medium were examined.
