Demonstration of 156 Inch Motor with Segmented Fiberglass Case and Ablative Nozzle. Volume I--Motor Design and Fabrication.

摘要

The objective of this program was to successfully test fire a one million pound thrust class, 156 in diameter, segmented FRP case, solid propellant rocketmotor, followed by the hydroburst test of the fiberglass case. Volume 1 contains a program summary; detailed discussions on the design and fabrication of the motor components, including the segmented fiberglass reinforced plastic case, the propellant and the grain, insulation and liner, ignition system and the nonhydroclaved nozzle; and subscale joint seal development. Insulation materials included silica cloth phenolic, asbestos- filled and silica-filled NBR (nitroso- butadiene rubber). Details on epoxy bonding materials are also given. Ablative nozzle materials were graphite cloth phenolic, carbon cloth phenolic, silica cloth phenolic and glass cloth phenolic. The joint seal material was neoprene rubber (MIL-R-417) WITH NYLON BACKUP RINGS. (AH-PL)
