Archive image from page 94 of Development of a spherical acrylic. Development of a spherical acrylic plastic pressure hull for hydrospace application . developmentofsph00stac Year: 1970 to which the structure will be subjected the largest percentage of time during its operational life. Since the test fixtures and test details associated with the hydrostatic testing of capsule specimens varied to some extent between the model and large-scale specimen tests, they will be described separately. Testing of Models. Fifteen-inch capsule models were subjected to a large variety of hydrostatic tests in order to provide experimental data on as many facets of capsules' structural response to hydrostatic loading as possible. The hydrostatic pressure tests to which the model capsules were subjected can be divided into three general categories: (1) short-term tests, (2) long- term tests, and (3) cyclic tests. In addition to the hydrostatic tests, a single axial compression test was also performed. Figure 59. Hatch for the operational 15-inch-diameter model capsule: open. 91
