Specification for tank assemblies, positive expulsion, propellant reaction control subsystem design control
A 1964 NASA engineering specification for positive-expulsion propellant tanks in the Apollo spacecraft reaction control subsystem, issued unsigned as a contractor design-control document. The two plates are photocopied line drawings: a dimensioned tank elevation with leader-labeled ports and a bottom-view bolt circle, plus a plumbing schematic of valves, regulators and paired tanks in a ruled border.
