The Pratt & Whitney J57 (company designation: JT3C) is an axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s. The J57 (first run January 1950 [ 1 ] ) was the first 10,000 lbf (45 kN) thrust class engine in the United States.
One XT57 (PT5), a turboprop development of the J57, was installed in the nose of a JC-124C (BuNo 52-1069), and tested in 1956. [3] [4]Rated at 15,000 shaft horsepower (11,000 kW), the XT57 was the most powerful turboprop engine in existence at the time, [5] and it remains the most powerful turboprop ever built in the United States.

The Pratt & Whitney JT3D is an early turbofan aircraft engine derived from the Pratt & Whitney JT3C turbojet. It was first run in 1958 and was first flown in 1959 under a B-45 Tornado test aircraft. Over 8,000 JT3Ds were produced between 1959 and 1985.
Eighteen C-135As (Boeing model number 717-157 [8]), powered by Pratt & Whitney J57 turbojets, were built. In later years, almost all were upgraded with Pratt & Whitney TF33 turbofan engines and wide-span horizontal stabilizers, and were re-designated C-135E.
Jet engine manufacturer Pratt & Whitney said Thursday it is launching a new version of its next-generation geared turbofan engine for Airbus, its largest commercial customer, as the French plane ...
P&W J52-P-408 being worked on in the USS Kitty Hawk's jet shop. The Pratt & Whitney J52 (company designation JT8A) is an axial-flow dual-spool turbojet engine originally designed for the United States Navy, [2] in the 40 kN (9,000 lbf) class. It powered the A-6 Intruder and the AGM-28 Hound Dog cruise missile.
The Pratt & Whitney JT9D engine was the first high bypass ratio jet engine to power a wide-body airliner. [ 46 ] The lower the specific thrust of a turbofan, the lower the mean jet outlet velocity, which in turn translates into a high thrust lapse rate (i.e. decreasing thrust with increasing flight speed).
(Reuters) - Wizz Air on Tuesday said it had signed a new support agreement with defence and aerospace firm RTX's Pratt & Whitney amid engine woes, adding that it expects 40 of its planes to stay ...
