Pratt & Whitney is an American aerospace manufacturer with global service operations. It is a subsidiary of Raytheon Technologies. Pratt & Whitney's aircraft engines are widely used in both civil aviation and military aviation. Its headquarters are in East Hartford, Connecticut. As one of the "big three" aero-engine manufacturers, it competes with General Electric and Rolls-Royce, although it has also formed joint ventures with both of these companies. In addition to aircraft engines, Pratt & Whitney manufactures gas turbines for industrial and power generation, and marine turbines. In 2017, the company reported that in 2014 they had 38,737 employees supporting more than 11,000 customers in 180 countries around the world. In 2013, Pratt & Whitney's revenue totaled $14.5 billion.
The Pratt & Whitney JT9D engine was the first high bypass ratio jet engine to power a wide-body airliner. Its initial application was the Boeing 747-100, the original "Jumbo Jet". It was Pratt & Whitney's first high-bypass-ratio turbofan.
The LHTEC T800 is a turboshaft engine for rotary wing applications. It is produced by the LHTEC, a joint venture between Rolls-Royce and Honeywell. The commercial and export version is the CTS800. The engine was primarily developed for the United States Army's cancelled RAH-66 Comanche armed reconnaissance helicopter, but has found use in other applications.
The MTU Turbomeca Rolls-Royce MTR390 is a turboshaft developed for light helicopter applications by MTU Turbomeca Rolls-Royce (MTR). The engine is designed to power helicopters in the weight range of 5-7 tonnes in both single and twin engine configurations. So far the only application is the Eurocopter Tiger. Test runs of the MTR390 began in 1989 and the first test flight was performed in 1991. The MTR390 received military certification in May 1996 and civil approval in June 1997.
Lycoming Engines is a major American manufacturer of aircraft engines. With a factory in Williamsport, Pennsylvania, Lycoming produces a line of horizontally opposed, air-cooled, four, six and eight-cylinder engines including the only FAA-certified aerobatic and helicopter piston engines on the market.
The Pratt & Whitney F100 is an afterburning turbofan engine manufactured by Pratt & Whitney that powers the F-15 Eagle and F-16 Fighting Falcon.
Pratt & Whitney Canada is a Canada-based aircraft engine manufacturer. PWC's headquarters are in Longueuil, Quebec, just outside Montreal. It is a division of the larger US-based Pratt & Whitney (P&W), itself a business unit of Raytheon Technologies Corporation. United Technologies has given PWC a world mandate for small and medium aircraft engines while P&W's US operations develop and manufacture larger engines.
The Pratt & Whitney Canada PW100 aircraft engine family is a series of 1,800 to 5,000 shaft horsepower turboprops manufactured by Pratt & Whitney Canada. Pratt & Whitney Canada dominates the turboprops market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engine Company.

The Pratt & Whitney X-1800 was an H-block aircraft engine project developed between 1938 and 1940, which was cancelled with only one example being built.
LHTEC is a joint venture between Rolls-Royce and Honeywell. The company was originally a partnership between the Allison Engine Company and AlliedSignal Aerospace. In 1995 Rolls-Royce acquired Allison, and AlliedSignal merged with Honeywell in 1999, and adopted its name.
The Garrett TPF351 is a turboprop engine designed by Garrett Engine Division of AlliedSignal Aerospace Company. Initiated by Garrett in October 1987, the TPF351-20 engine was selected by Embraer to power the Embraer/FMA CBA 123 Vector, a high-speed commuter "pusher" aircraft. It was first tested on May 19, 1989 and then ground tested and flight tested on a Boeing 720 on July 9, 1990. The first prototype CBA 123 was tested on July 18, 1990, followed by a flight to the Farnborough Air Show in September of the same year. Both programs were cancelled in 1992, when the TPF351 was nine months from engine certification.
The Pratt & Whitney Canada PW800 is a turbofan engine in the 10,000–20,000 lbf (44–89 kN) thrust class, under development by Pratt & Whitney Canada. Intended for the regional jet and business jet market, the gear-less PW800 shares a common core with the larger, geared PW1000G. The first variants were certified on February 15, 2015, to power the new Gulfstream G500/G600.
Pratt & Whitney Rocketdyne (PWR) was an American company that designed and produced rocket engines that use liquid propellants. It was a division of Pratt & Whitney, a fully owned subsidiary of United Technologies Corporation. It was headquartered in Canoga Park, Los Angeles, California. In 2013, the company was sold to GenCorp, becoming part of Aerojet Rocketdyne.
The HAL HTSE-1200 is a turboshaft engine under development by India's Hindustan Aeronautics Limited (HAL). It is aimed at 3.5 ton single engine class and 5-8 ton twin engine class helicopter configurations. India will need 5,000-6,000 helicopters to operate in 2020s. This will be an indigenous design giving engine alternatives for the HAL-developed LUH, ALH and LCH. The first run of engine was conducted in February 2018 when it achieved 76% of the rpm required.
