A Laboratory Apparatus for Testing and Assessing the Effects of Hot Rocket Gases on High Temperature Materials

Abstract

The selection of suitable rocket materials is dependent on the use of an apparatus for assessing their resistance to hot nascent rocket gases. By burning a certain mixture of ammonia and acetylene in oxygen, a stream of hot gases is produced similar in composition and temperature to the combustion products of a kerosene-nitric acid propellant. A laboratory test rig, employing an ammonia-acetylene-oxygen flame is described together with mode of operation Full details of construction and temperature measurement are given. Test specimen temperatures of about 2400 deg C are attained and the resistance of the specimen is measured in terms of weight and dimension changes.
