Abstract

A number of methods of determining quantities are described which define the flow in lowdensity, hypersonic wind tunnels which use plasma generators to heat the working fluid. Although the fluid was heated to a plasma state initially, with a typical bulk temperature of 12,000 R, the measurements reported were for the purpose of calibrating the flow in the aerodynamic nozzle of a wind tunnel where it is descriable that the fluid be recombined before or during the expansion to high speeds. All of the methods considered may be classed as gasdynamic or aerodynamic as opposed to, say, spectroscopic methods. Measurements of total enthalpy, total and static pressure, and local mass flux are discussed, with descriptions of the equipment and typical results included. The emphasis is placed on procedures not requiring assumptions for the data reduction which cannot be checked. An appendix containing an account of the effect on nozzle flow which was caused by one method of swirling gas injection into the plasma generator electrode section is also included.
