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.

Continental Aerospace Technologies is an aircraft engine manufacturer located at the Brookley Aeroplex in Mobile, Alabama, United States. It was originally spun off from automobile engine manufacturer Continental Motors Company in 1929 and owned by Teledyne Technologies from 1969 until December 2010. The company is now part of Aviation Industry Corporation of China (AVIC), which is a Government of the People's Republic of China state-owned aerospace company headquartered in Beijing.
Volvo Aero was a Swedish aircraft, guided missiles and rocket engine manufacturer. It became GKN Aerospace Engine Systems following the company's acquisition by British engineering conglomerate GKN during 2012.
The Honeywell TPE331 is a turboprop engine. It was originally designed in the 1950s by Garrett AiResearch, and produced since 1999 by Honeywell Aerospace. The engine's power output ranges from 575 to 1,650 shaft horsepower.
Magellan Aerospace Corporation is a Canadian manufacturer of aerospace systems and components. Magellan also repairs and overhauls, tests, and provides aftermarket support services for engines, and engine structural components. The company's business units are divided into the product areas of aeroengines, aerostructures, rockets and space, and specialty products. Its corporate offices in Mississauga, Ontario, Magellan operates in facilities throughout Canada, the United States, and the United Kingdom.
The Garrett TFE731 is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace.
The Honeywell AGT1500 is a gas turbine engine. It is the main powerplant of the M1 Abrams series of tanks. The engine was originally designed and produced by the Lycoming Turbine Engine Division in the Stratford Army Engine Plant. In 1995, production was moved to the Anniston Army Depot in Anniston, Alabama, after the Stratford Army Engine Plant was shut down.
The Lycoming ALF 502/LF 507 is a geared turbofan engine produced by Lycoming Engines, AlliedSignal, and then Honeywell Aerospace.
The Honeywell/ITEC F124 is a low-bypass turbofan engine derived from the civilian Honeywell TFE731. The F125 is an afterburning version of the engine. The engine began development in the late 1970s for the Republic of China (Taiwan) Air Force AIDC F-CK Indigenous Defence Fighter (IDF), and it first ran in 1979. The F124/F125 engine has since been proposed for use on other aircraft, such as the T-45 Goshawk and the SEPECAT Jaguar, and currently powers the Aero L-159 Alca and the Alenia Aermacchi M-346. The F124 has a rather unusual design for a two spool gas turbine engine, using both axial and centrifugal compressors in its high-pressure compressor. There are currently only three production variants of the engine, although several more have been proposed throughout its lifespan.
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.
Honeywell Aerospace is a manufacturer of aircraft engines and avionics, as well as a producer of auxiliary power units (APUs) and other aviation products. Headquartered in Phoenix, Arizona, it is a division of the Honeywell International conglomerate. It generates approximately $10 billion in annual revenue from a 50/50 mix of commercial and defense contracts.
Garrett AiResearch was a manufacturer of turboprop engines and turbochargers, and a pioneer in numerous aerospace technologies. It was previously known as Aircraft Tool and Supply Company, Garrett Supply Company, AiResearch Manufacturing Company, or simply AiResearch. In 1964, Garrett AiResearch merged with Signal Oil & Gas to form a company renamed in 1968 to Signal Companies, which in 1985 merged with Allied Corp. into AlliedSignal. In 1999 AlliedSignal acquired Honeywell and adopted the Honeywell name.
The CFE Company is a joint venture established by GE Aviation and the Garrett Engine Division of Allied Signal in June 1987. The company produces the CFE738, a small turbofan engine used on the Dassault Falcon 2000. "CFE" stands for "Commercial Fan Engines".
The Honeywell T55 is a turboshaft engine used on American helicopters and fixed-wing aircraft since the 1950s, and in unlimited hydroplanes since the 1980s. Today, there have been more than 6,000 of these engines built. It is produced by Honeywell Aerospace, a division of Honeywell based in Phoenix, Arizona, and was originally designed by the Turbine Engine Division of Lycoming Engines in Stratford, Connecticut, as a scaled-up version of the smaller Lycoming T53. Both engines are now produced by Honeywell Aerospace, and the T55 serves as the engine on several major applications including the CH-47-Chinook, the Bell 309, and the Piper PA-48 Enforcer. The T55 also serves as the core of the Lycoming ALF 502 turbofan. Since the T55 was first developed, progressive increases in airflow, overall pressure ratio, and turbine inlet temperature have more than tripled the power output of the engine.
John Clifford Garrett was an American entrepreneur who founded a company in Los Angeles in 1936 which came to be known as Garrett AiResearch. The company was first named Aircraft Tool and Supply Company, then by early 1937 was renamed as Garrett Supply Company, and by 1939, AiResearch and shortly thereafter AiResearch Manufacturing Company, which then became a division within the Garrett Corporation.
Solar Turbines Incorporated, a wholly owned subsidiary of Caterpillar Inc., designs and manufactures industrial gas turbines for onshore and offshore electrical power generation, for marine propulsion and for producing, processing and transporting natural gas and oil.
A free-turbine turboshaft is a form of turboshaft or turboprop gas turbine engine where the power is extracted from the exhaust stream of a gas turbine by an independent turbine, downstream of the gas turbine. The power turbine is not mechanically connected to the turbines that drive the compressors, hence the term "free", referring to the independence of the power output shaft. This is opposed to the power being extracted from the turbine/compressor shaft via a gearbox.
