Abstract:
Detailed measurements of static and impact pressures in the nozzle of a low-density wind tunnel are presented. Purpose of the investigation was to determine the extent to which the nozzle of the Low-Density, Hypervelocity Tunnel may be used in an overexpanded mode of operation. Expansions to static pressure from one-fourth to one-fifth of the pressure outside the exit of the nozzl are shown to be feasible with the nozzle having a nominal Mach number of 10 and boundary-layer thickness approaching nozzle radius at the exit.
