An Experimental Investigation of the Use of Nitrous Oxide in Hypersonic Wind Tunnel Testing Facilities
Abstract
Various continuous flow hypersonic wind-tunnel testing facilities are discussed in general and the possibility of employing the exothermic decomposition of nitrous oxide to generate high temperature air is considered in detail. The feasibility of establishing high enthalpy air streams by mixing pre-heated nitrous oxide with a hot stream of nitrogen which was heated separately to temperatures ranging from 1033 deg K to 1264 deg K was investigated experimentally. The temperatures of the pre-heated nitrous oxide ranged from 875 deg K to 1055 deg K. After the decomposition of the nitrous oxide the gas mixture attained temperatures between 859 deg K and 1807 deg K. When the decomposition process was incomplete the reacted gas contained a substantial quantity of nitrogen dioxide and nitrogen tetroxide. On the other hand only about 1% of these products was formed when the reaction went to completion. The highest temperature of the reacted products amounted to 1807 deg K which indicates that nearly 80% of the theoretical temperature rise was obtained.
