FILAMENT-WOUND PRESSURE VESSELS.
Abstract
Air pressure storage vessels are required in high-performance aircraft to perform various emergency functions. Glass filament-wound bottles afford a substantial weight savings over steel, and are less subject to corrosion problems. However, they have been subject to fatigue failures because of the stresses imposed on the relatively weak resin binder system. By redesigning the spherical bottle to a cylindrical shape having isotensoid dome ends, and by using the MultiShell method of fabrication, a weight savings of 10% to 15% coupled with an increase in ultimate burst pressures of 15% to 30% has resulted. This redesigning takes advantage of the unidirectional strength characteristics of the glass filament and reduces the stress on the resin binder system to an acceptable level. Results of comparative testing on the redesigned vessels and on Government furnished vessels indicate that the specifications for vessel performance should be materially upgraded. Changes in MIL-T-25363B to reduce costs and increase reliability are recommended. (Author)
