Book Exploratory Evaluation of Alumina Ceramic Cylindrical Housings for Deep Submergence Service The Second Generation NOSC Ceramic Housings

Download or read book Exploratory Evaluation of Alumina Ceramic Cylindrical Housings for Deep Submergence Service The Second Generation NOSC Ceramic Housings written by Jerry D. 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.

Book Exploratory Evaluation of Alumina Ceramic Housings for Deep Submergence Service Fourth Generation Housings

Download or read book Exploratory Evaluation of Alumina Ceramic Housings for Deep Submergence Service Fourth Generation Housings written by and published by . This book was released on 1990 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned vehicles operating at depths in excess of 10,000 feet require for the optimization of their performance parameters (i.e., speed, range, payload, maneuverability) pressure hulls with a low weight-to- displacement ratio, preferably less than 0.5. Such low weight-to-displacement ratios cannot be achieved with metallic pressure hulls because of their low specific strengths. Aluminum oxide ceramics possess specific strength in the 82, 000 to 139,000 psi range, which is adequate for achieving a 0.5 weight-to- displacement ratio in pressure hulls fabricated from the material. The intrinsic cost of the material is low (less than $0.2/pound). The material is nonmagnetic, impervious to water, inert in seawater, a good conductor of heat, and possesses a high modulus of elasticity. Its major drawback is brittleness, which results in low point impact resistance. There appears to be also a limitation in the maximum size that can be fabricated by the present manufacturing process.
