We’ve completed machining our subscale tank test endcaps! These are almost half scale parts (1:1.97) which will be attached to subscale tanks, for pressure, cryogenic sealing, and hydraulic testing this summer. They were all machined out of 6061 T6 Aluminum, with a nominal maximum OD of 6 inches at the flange. There are two designs shown below: welded (right) and circumfrentially bolted with O-ring seals (left) bulkheads. Both are set for testing and will decide which configuration we use based on testing. The welded design is lighter but less modular and less serviceable.
