Pratt & Whitney J57-P-29W Turbojet Engine, Cutaway
The production engine was the first to reach and exceed 10,000 pounds (4535 kilograms) of static thrust; as a result, the North American F-100 became the first mass-produced fighter to reach supersonic speed in level flight.
It powered several other military airplanes, including the McDonnell F-101, Convair F-102, Douglas A3D and F4D, Chance Vought F8U, and Boeing B-52 and KC-135. It also powered the Boeing 707 and 720, and Douglas DC-8 commercial airplanes.
In 1953, the Collier Trophy, U.S. highest aviation honor, was awarded to Leonard Hobbs, Chief Engineer of Pratt & Whitney Division of United Aircraft Corp. for his development work on this engine.
During the 15 years that this engine was produced – until 1965 – more than 20,000 were manufactured for civilian (JT3), and military (J57) use.
