From Wikipedia, the free encyclopedia

Original:

A vestibule is composed of an ACBM ring (1) mounted to a flanged bulkhead (3) and a PCBM ring (2) mounted to a flanged bulkhead or barrel section (4). The rings, both machined from 2219 Aluminum forgings, mate at a “molded seal” (5); each ring is sealed at its inboard end by a pair of concentric o-rings (6). Shown here “mid-span” between the Powered Bolt locations, three internal loads try to pry the joint open: atmospheric pressure (Fa) (15.2 psia), seal compression (Fs) and flange conformance (Fc). This artist's rendering of a generic cross-section also shows (in blue) where air can leak to the vacuum of space.
