EVALUATION OF LOW-COST MATERIALS AND MANUFACTURING PROCESSES FOR LARGE SOLID ROCKET NOZZLES. ANALYSIS OF PERFORMANCE, NOZZLE 6.

Abstract

This is the sixth in a series of reports describing the results of static test firings conducted to verify the performance of ablative nozzle components fabricated from low-cost materials and/or using low-cost manufacturing processes. The throat insert of nozzle 6 was fabricated from AVCERAM C/S reinforcement and the throat extension from canvas duck. Spallation was observed in the throat, caused by one or both of the following: (1) low breaking strength of the fabric, and (2) damage to the fabric during wrapping. The throat extension of canvas duck performed well. Anisotropic material deposition was observed in the char of the AVCERAM C/S composite. The canvas duck composite exhibited excellent cost advantages for use in the throat extension. (Author)
