Abstract
A device has been produced which can detect the contamination of the t est gas by the driver gas in a reflected shock tunnel. This device mon itors the static pressure in a converging duct. The duct is designed t o choke at a predetermined contamination level due to the change in th e specific heat ratio produced by the contaminants. Experimental resul ts are given for a freestream enthalpy of nominally 6 MJ/kg.
