1946 RESTRICTED Jet Propulsion Manual – JPL / Caltech – Complete Technical Binder w/ Charts, Photos & Classified Sections
Offered here is an exceptional and complete 1946 RESTRICTED Jet Propulsion reference manual, prepared jointly by the Guggenheim Aeronautical Laboratory and the Jet Propulsion Laboratory (Caltech) for the Air Technical Service Command in the immediate post‑WWII period. This is an original classified technical binder from the era when American jet propulsion, rocket research, and gas‑turbine development were transitioning from wartime innovation into the foundations of modern aerospace engineering. This binder is collector‑grade, containing multiple intact sections, technical chapters, mathematical derivations, photo plates, and original graph inserts. The pages include “RESTRICTED” markings throughout, along with an Espionage Act notice on the title page — a hallmark of genuine mid‑century military technical documentation. Key Features
Complete 1946 restricted manual produced by JPL & CaltechOriginal enthalpy–entropy charts, thermodynamic tables, and engineering graphs
Photo plates of early gas‑turbine installations
Detailed chapters on jet propulsion, centrifugal compressors, gas turbines, and rocket propulsion
Authentic mid‑century binding with backwards‑bound pages typical of government technical compilations
No missing sections from what is visible; diagrams and inserts remain intact
Espionage Act warning on title page confirming original restricted status
Excellent vintage condition. Binder shows expected age‑appropriate wear but remains structurally sound. Pages are clean, legible, and complete, with inserts and technical plates preserved. This is not a reproduction.
This manual is ideal for serious collectors of: Early jet propulsion historyJPL / Caltech archival material
