Research Achievements Review, volume 4, no. 6: Chemical propulsion research at MSFC
A 1972 NASA Research Achievements Review volume reporting chemical propulsion work at Marshall Space Flight Center, compiled by agency staff for engineers and program managers. The plates are dark halftone photographs of bench hardware — bolted flange rings, metal bellows assemblies, and instrumented test fixtures — annotated with leader lines, part names in capitals, and inch scale bars, useful for circular machined forms, callout typography, and high-contrast grey-on-black texture.
