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.

The Lockheed T-33 Shooting Star (or T-Bird) is an American subsonic jet trainer. It was produced by Lockheed and made its first flight in 1948. The T-33 was developed from the Lockheed P-80/F-80 starting as TP-80C/TF-80C in development, then designated T-33A. It was used by the U.S. Navy initially as TO-2, then TV-2, and after 1962, T-33B.

Eight Pratt & Whitney TF33 engines power the U.S. Air Force’s B-52 Stratofortress long-range, heavy bomber that is capable of flying at high subsonic speeds at altitudes up to 50,000 feet. It can carry nuclear or precision guided conventional …

The Pratt & Whitney TF33 turbofan engine was developed from the highly successful Pratt & Whitney J57 engine core. Starting in 1960, the civilian version (designated the JT3D) powered the Boeing 707-120 and McDonnell Douglas DC-8 airliners. The TF33 military version powered the Boeing B-52H Stratofortress and KC-135s.

2025年3月6日 · The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, a 14-stage compressor section (7-stage intermediate pressure, 7-stage high-pressure) and and a 4-stage turbine (1-stage high-pressure, 3-stage low-pressure). The TF33-P-3 has a maximum continuous power rating of 14,500 pounds of thrust (64.499 kilonewtons) at 9,750 r.p.m., N1.

2023年11月16日 · Pratt & Whitney, an RTX subsidiary, has agreed to sustain the US Air Force’s (USAF) TF33 engines, which power the service’s B-52 Stratofortress and E-3 Sentry aircraft. In a 15 November press release, the contractor committed to establish a new and “holistic sustainment solution” to reduce obsolescence.

2023年11月16日 · Pratt & Whitney, a part of Raytheon Technologies, has secured a contract worth up to $870 million from the US Defense Logistics Agency (DLA) for the sustainment of TF33 (also known as JT3D) engines.

2015年6月6日 · The Air Force began using the TF33 to power B-52 Stratofortresses in March 1961 and it still uses them today. The engine also has been keeping E-3 Sentry Airborne Warning and Control System planes flying since 1973, according to Pratt & Whitney. The company built about 8,600 TF33s for commercial and military use since production began in 1959.

The Air Force currently owns approximately 2,300 TF33 engines of various models that it uses on seven weapons systems, mainly the KC-135, E-3 Advanced Warning and Control Systems (AWACS), B-52, and E-8 (Joint Surveillance and Target Attack …

The TF33 low-bypass turbofan engine, developed by the American company Pratt & Whitney has been made on the basics of the civil JT3D engine.
