PYROLYTIC CARBIDE DEVELOPMENT PROGRAM
Abstract
Two symmetric Polaris nozzles were coated with niobium carbide during the investigation of the carbide coating of full scale nozzles. A concentrated effort was made to eliminate non-uniformity of deposits and the non-reproducibility of deposition rates due to growth formations on injector tips. An injector evaluation study has resulted in improved injector performance. One hafnium carbide coated nozzle was fired for evaluation; the coating failed in five seconds. (Author)
