Development of a spherical acrylic plastic pressure hull for hydrospace application . developmentofsph00stac Year: 1970 to assembly varied from to inches and to inches, respectively, while the external sphericity and the diameter of the assembled capsule varied from to inches and to inches, respectively. The difference between sphericity measurements taken on indi- vidual pentagons and on the finished hull are attributed in a large measure to (1) mismatch between individual pentagons during assembly, (2) excessive polishing and buffing of the joint surface areas, and (3) difference in measuring techniques (in one case dial indicator measurement of internal radius while in the other case template measurement of the external radius). Figure 56. Measuring the diametral deviations of the bonded 66-inch capsule with a 66-inch-throat micrometer. The magnitudes of sphericity, thickness, and diametral deviations from specified nominal values when related to the size of the large-scale capsule show that these deviations are approximately of the same magnitude as those mea- sured on model capsules. While the relative sphericity deviation from the specified internal radius on scale models was within + and , on the large-scale acrylic plastic hull it was within + and The relative diametral deviation from nominal diameter for scale models was within + and , while the large-scale hull's diametral deviations were within + and Since the comparison of relative dimensional deviations has 85
