This book was released on 1993 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test program has been conducted to develop design concepts for assembling large external pressure housings from ceramic cylinders and hemispheres by joining them with removable titanium joint rings and split wedge bands. The proposed design concepts have been validated with 6- and 12-inch- diameter housings assembled from many interchangeable housings components. The test results show that there appears to be no reduction in structural performance under external pressure associated with (1) linear scaling up of ceramic housing components, and (2) the presence of inclusions

Book excerpt: A test program has been conducted to develop design concepts for assembling large external pressure housings from ceramic cylinders and hemispheres by joining them with removable titanium joint rings and split wedge bands. The proposed design concepts have been validated with 6- and 12-inch- diameter housings assembled from many interchangeable housings components. The test results show that there appears to be no reduction in structural performance under external pressure associated with (1) linear scaling up of ceramic housing components, and (2) the presence of inclusions or voids 0.05 inch in diameter. Weight-to-displacement of 0.6 has been achieved by housings assembled from 94-percent alumina monocoque cylinders and hemispheres designed not to exceed - 150,000 psi compressive stress. The cyclic fatigue life of the ceramic components is determined by the rate of crack growth on the ceramic bearing surfaces under axial bearing loading. The rate of crack growth is minimized by encapsulating the ends of ceramic components in titanium end rings filled with epoxy adhesive. The height of the flanges on the circular, U-shaped end caps is critical for the cyclic fatigue life of the plane bearing surfaces on the ceramic cylinders and hemispheres. The fatigue life of cylinders is 500 pressure cycles to design pressure when their ends are protected by NOSC Mod 1 end caps with flanges whose height h = 3.22x cylinder thickness.

Stachiw and published by . This book was released on 1987 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scale model ceramic pressure housing assemblies have been designed, fabricated, and pressure-cycled 2,000 times to the 9,000-psi external design pressure without failure. The Model 1 cylinder, fabricated from 99.5-percent alumina ceramic, is 9 inches long and has an inside diameter of 5.624 inches and an outside diameter of 6.00 inches. The Model 2 cylinder, fabricated from 94-percent alumina ceramic, is the same as Model 1 in length and inside diameter, but its outside diameter is 6.037 inches. Each housing assembly was either a single cylinder or two cylinders of the same model joined together. The single cylinder housing assembly consisted of a cylinder and two titanium spherical end closures with a 5.624-inch inside diameter and a 0.136-inch thickness, that provided radial support for the ends of the cylinder. The two-cylinder assemblies were radially supported and joined together by a titanium T-ring in the center, and by titanium spherical end closures at either end od the lengthened cylinder. Fretting of the bearing surfaces on the ends of ceramic cylinders was eliminated by fitting the ends of the cylinders with U-shaped titanium rings held in place by epoxy adhesive. The weight-to-displacement ratio of the pressure housing assembly was 0.57.
