Abstract
A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include a plurality of trunnion mounts. A first four of the trunnion mounts may be coupled between a front half of the inner tank and a front half of the outer tank. A second four of the trunnion mounts may be coupled between a rear half of the inner tank and a rear half of the outer tank. The trunnion mount may be further strengthen with a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank.
