Development of Pyrolytic Graphite/Silicon Carbide Composite Materials for Rocket-Nozzle Applications. Volume I. The Injector Deposition Furnace.

Abstract

A series of instrumented engineering tests with a chemical vapor deposition furnace used to prepare pyrographite/silicon carbide codeposited material for rocket nozzle applications is described. Flow into the furnace is an axisymmetric confined jet with high Reynolds and low Mach number. The gas flow within the furnace is characterized by a large separated flow region with associated hot spot and a high level of turbulence. Methods of instrumenting and collecting data, methods for defining the furnace and process characteristics, test procedures, recording and reducing data, data analysis, and model development are documented. Analytical models of the furnace during transient and steady state operation were developed and the results compared with the data obtained. Characterization of the coatings obtained and the associated deposition kinetics are also presented. (Author)
