DEVELOPMENT AND DEMONSTRATION OF NOZZLES USING BULK PYROLYTIC GRAPHITE

Abstract

This report is a summary of the first three months of effort on the development of nozzles using bulk pyrolytic graphite. The first 1.120 inch nozzle has been designed and component parts will be fabricated during the next period. The first unit utilizes a plane oriented insulating pyroid insert and was selected from four variations of this approach. Preliminary heat transfer, temperature profile, stress and erosion calculations have been performed for the initial design and these calculations will be used in conjunction with test firing results to design the larger 2.3 inch demonstration nozzles. Design of the second development nozzle has been initiated and is partially completed. This unit utilizes partial edge oriented approach to compare performance with the plain oriented unit.
