Abstract : Two replicate columbium carbide nozzles were designed and fabricated. They were tested at the Rocket Propulsion Laboratory in the 5,000 pound solid-propellant char motor. Although minor difficulties occurred at the attachment fitting because of a subsequent change in test vehicle, the performance of the refractory carbide material from a standpoint of thermal shock resistance was excellent. The erosion performance was also good. (Author)
