Pressure Resistant Ceramic Housings for Deep Submergence Systems

Abstract

The weight-to-displacement ratio of 0.60 achieved in the NOSC ceramic materials program by a ceramic housing assembly with a 12-inch diameter and 84- inch length is the lowest ratio achieved to date with a ceramic or glass housing for 20,000-foot operational depth with a payload capability in excess of 100 pounds. This ratio can be reduced further to 0.5 for his housing design by substituting 7150-T7E97 aluminum alloy for titanium joint housing components and raising the design stress in ceramic from 150,000 to 175,000 psi. Keywords: Titanium alloys, Alumina ceramic, External pressure housings, Deep submergence vehicles.
