Original vintage technical manual from 1965, featuring early computer-generated graphics and diagnostic schematics for the Pratt & Whitney JT3D (military designation TF33) turbofan engine—the powerhouse that redefined the economics of the Jet Age.

This manual represents a landmark in both aviation and technological history, it showcases the nascent use of computer-aided design (CAD) and vector-based computer graphics to illustrate complex aerospace components. During this period, pioneers like William Fetter at Boeing were coining the term "computer graphics," and this manual serves as a physical bridge between traditional drafting and the digital future.

The JT3D engine itself was the first commercial production turbofan from Pratt & Whitney, most famously powering the iconic Boeing 707 and the Douglas DC-8. By introducing the turbofan architecture, the JT3D increased thrust by 35% while drastically reducing fuel consumption, effectively making long-haul international jet travel affordable for the general public.

This manual captures the "technical sublime" of the 1960s. This is a rare artifact documenting the moment when the "slide rule" era of aviation first met the digital processing power of the mainframe age.

Measures approximately 8 x 10.5 inches; includes detailed fold-out diagrams and computer-plotted performance charts over 40+ pages

Excellent vintage condition with 'dup' inked on the front in period blue ink, crisp pages and minor shelf wear to the binding; a superior reference copy.
