Study of Production Methods for High Temperature Solid Propellant Motor Nozzles.

Abstract

The program investigated low-cost fabrication processes to permit the use of advanced materials in nozzles to achieve high performance in a severe motor environment (2000 psi - 20 sec - 100 lb/sec flow). Three materials and manufacturing processes were selected as primary candidates by an initial screening process. Detailed full-scale nozzle designs were developed for each of the candidates. Performance was evaluated in subscale motor firings. A final selection was made and is recommended for demonstration in a full size nozzle test. The sleected material is a carbon-carbon composite, manufactured from a graphite cloth layup (preform) by carbonization and successive resin infiltration/carbonization cycles for densification (> 1.45 gm/cc) and graphitization. A program plan was developed to manufacture and test the nozzle in the specified motor environment. (Author)
