✦ Synopsis

ABSTRACTS 715 described. Such material has been used to advantage as a flat or curved monochromator for X-rays and is convenient for determining some of the fundamental properties of graphite.

38. The use of pyrolytic graphite in uncooled rocket nozzles

A. C. Parmee (Research Division, Rocket Propulsion Establishment, Aybbwy, Buckinghamshire, U.K.). Tests in rocket motors over a range of combustion conditions have shown pyrolytic graphite to be markedly superior to other forms of carbon and graphite. Two nozzle designs incorporating pyrolytic graphite in the form of a shell and disc were used to establish its limits of performance over a wide range of rocket motor conditions. The results of this work, techniques used in the manufacture and testing of the pyrolytic graphite nozzles are described. The results suggest there is a possible link between deposition conditions, which cause slight differences in structure and erosion resistance.
