Attachment 2_852601-1011_B-BULKHEAD-PRESSURE_TANK_DISTRO_A.pdf

This is a technical drawing specification document for a pressure tank bulkhead component. The document is marked "FOR OFFICIAL USE ONLY" and is approved for public release with unlimited distribution.

The drawing provides detailed engineering specifications for a bulkhead pressure tank assembly. Key specifications include material composition per NASA-STD standards, post-processing requirements involving heat treatment schedules for laser powder directed energy deposition components, stress relief procedures, hot isostatic pressing requirements at specified temperatures and pressures, and rapid quench cycling protocols. The document mandates surface finishing to 125 microinches except as noted, with dimensional tolerances per ASME Y14.5M-2009. The design incorporates multiple mounting holes arranged in a circular pattern around a central hub, with precise measurements including diameters ranging from approximately 11.250 inches to 0.850 inches. The section view (A-A) details the cross-sectional geometry with specific wall thicknesses and radial dimensions. The revision control indicates an initial release date of 3/06/2021 and a public release date of 2/16/15. This is a component-level drawing suitable for manufacturing and quality assurance purposes, with no procurement-related information, response dates, or contract terms included.
