Summary

AN IMPROVED WAY TO INCREASE THE REYNOLDS NUMBER CAPABILITY OF WIND TUNNELS HAS BEEN DEVELOPED AT THE NASA THROUGH THE APPLICATION OF CRYOGENIC TECHNOLOGY. COOLING THE TEST GAS IN THE WIND TUNNEL TO CRYOGENIC TEMPERATURES BY SPRAYING LIQUID NITROGEN INTO THE TUNNEL CIRCUIT INCREASES THE TEST REYNOLDS NUMBER BY AS MUCH AS A FACTOR OF 7 WITH NO INCREASE IN DYNAMIC PRESSURE AND WITH A REDUCTION IN DRIVE POWER.
