INVESTIGATION OF ADVANCED DESIGN CONCEPTS FOR DEEP SUBMERSIBLES.
Abstract
This program investigated design concepts of filament-wound deep-diving submersible vehicles. Small scale cylindrical shell models were designed, fabricated and tested under hydrostatic external pressure. Model configurations evaluated include ring-stiffened cylinders with both constant and variable wall thickness between ring stiffeners, sandwich-wall and bilayer designs. The target collapse pressure was 13,333 psi. Problems of major concern were development of analytical techniques to predict stress levels and buckling pressures, discontinuity loads at the model ends, adhesive bonds in the sandwich-wall models, obtaining hollow glass with the desired hollowness ratio and defining material properties.
