EVALUATION OF LOW COST MATERIALS AND MANUFACTURING PROCESSES FOR LARGE SOLID ROCKET NOZZLES. ANALYSIS OF PERFORMANCE, NOZZLE NO. 8.
Abstract
This is the eighth 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 material and/or using low-cost manufacturing processes. The throat approach, throat extension, and exit extension of nozzle 8 were fabricated from canvas duck phenolic; the entrance cap and throat inlet were fabricated from SNAP cured carbon fabric reinforced phenolic; and the throat was fabricated from a double-thick carbon fabric prepreg. Burn-through occurred at the thermocouple plug assembly of the throat approach, caused by improper bonding during assembly. Despite the burn-through, the excellent cost/performance effectiveness of the canvas duck was verified. Severe delamination was experienced in the throat inlet section, which had been wrapped parallel to the centerline. (Author)
