A STUDY OF A GLASS FILAMENT-WOUND BODY FOR THE XM20 GAS GENERATOR.
Abstract
The report covers a study to determine the applicability of a glass filament-wound gas generator body (GFGG) to the XM20 gas generator development program. The results of the study indicated that the filament-wound construction, possessing high strength-to-weight ratio characteristics, was an ideal approach to the development of a lightweight gas generator body capable of withstanding a peak internal pressure of 2000 psi. The present filament-wound gas generator body weighs approximately 3.7 lb compared with 5.8 lb for an aluminum generator. It affords a safety factor of 300% based, not on the filament-wound shell structure, but on the bond strength between the adapter cap and the filament-wound shell. On the basis of the promising results achieved by this study, it is recommended that the glass filament-wound fabrication technique be considered for other propellant actuated device (PAD) applications where high strength-to-weight ratios, high length-to-diameter ratios, and ease of fabrication are principal requirements.
