CHEMICAL REACTIONS BETWEEN PROPELLANT GASES AND NOZZLE MATERIALS.
Abstract
To improve our understanding of the role of chemical reactions in the erosion of rocket nozzle materials, a laboratory study of probable reactions was carried out with graphite and refractory metal carbides. Hemispherical speci mens of AGOT, ZTA, and pyrolytic graphite were exposed to hot gas streams containing nitrogen, argon, carbon monoxide, carbon dioxide, H2O(g) and HCl(g) generated by a plasma torch. Erosion rates were measured over a range of temperatures from 2000 to 3000 K. Under the flow conditions in the torch flame, significant losses were observed with each of the gases. Oxidation by CO2 and H2O(g) was by far the most destructive effect. (Author)
