Abstract:

The difficulty in producing subscale test nozzle inserts with a high thicknessradius of curvature ratio has been bypassed by redesigning the inserts to incorporate a 0.100-in. liner thickness instead of the 0.150 in. thickness originally required. The emphasis on free standing pyrolytic graphite liners with suitable backup materials promises to increase the reliability of nozzle inserts during firing although the problems encountered in finish machining have increased substantially. Conseqently the ratio of parts shipped to liners fabricated has been reduced. Effort is being made to decrease the scrap rate through improved machining techniques. Author
