Archive image from page 192 of Development of a spherical acrylic. Development of a spherical acrylic plastic pressure hull for hydrospace application . developmentofsph00stac Year: 1970 Figure D-2. Equatorial ring and tapered pins needed for attaching the ring to the acrylic plastic capsule. The model capsule was fabricated in an identical manner to those already discussed in the main body of the report (Figure D-4), except that 10 radially tapered holes were drilled through the wall along the capsule's equator (Figure D-4). For implosion testing, the model was equipped (Figure D-5) with the simplified end closures (Figure 63) described in the main body of the report. The test condition for imploding the equatorial ring capsule was short-term pressurization at 100°F. The choice of this test condition was based on the program's need for implosion data on acrylic plastic capsules at various temperatures to establish the temperature-versus-implosion-pressure relationship of acrylic plastic capsules. Since the total number of model cap- sules available for the acrylic plastic hull program was limited, the implosion testing of the equatorial ring capsule had to satisfy two requirements. It had to establish the adequacy of the equatorial ring restraint design while at the same time it had to provide additional data for the study on the effect of temperatures on the implosion pressure of acrylic plastic capsules. 189
