One of the more serious problems associated with hypersonic wind tunnels of the blow-down variety is the obtaining of reliable pressure and temperature measurements. This report reviews the various types of instrumentation investigated for possible use in the ARL twenty inch hypersonic wind tunnel and illustrates the advantages and disadvantages of such instrumentation. Various types of flow visualization techniques are also discussed with emphasis on their applicability to possible use in the aforementioned tunnel. A description is also included of the high speed data acquisition system.
