The Engines of Pratt & Whitney
This book describes the evolution from piston engines to gas turbines by the engineers who created those engines. Included are hundreds of archival photographs, as well as over a dozen tables listing specifications and applications. The story starts with the founding of the company in the 1920's to provide reliable air-cooled piston engines to the military and to help create coast-to-coast commercial flight service. Pratt & Whitney quickly dominated commercial and military flight in the 1930's - ultimately providing half the horsepower of American engines during WWII. Jack Connors explains how Pratt & Whitney came from behind the competition on developing gas turbines after the war with the debut of the J57, which powered the B-52 in 1952 and later the Air Force Century Series fighters (F-100, F-101, F-102) and the Navy A3D, F4D, and F-8 airplanes.
