Flat Disc Acrylic Plastic Windows for Man-Rated Hyperbaric Chambers at the USN Experimental Diving Unit.

摘要

Flat disc acrylic plastic windows were designed,fabricated,evaluated and delivered to EDU for replacement of glass windows used to date. The large (window diameter = 6.950inches;thickness = 1.650inches) and the small (window diameter = 4.450inches,thickness = 1.040inches) windows have been found on the basis of an extensive evaluation program to be more than adequate for man-rated service under 450psi maximum operational pressure in steel flanges with Di (diameter of opening in flange) of 5.000and 3.000inches. All windows were proof tested to 675psi pressure at 120F ambient temperature prior to delivery. (Author)
