General Electric Company, doing business as GE Aerospace,[4] is an American aircraft engine supplier that is headquartered in Evendale, Ohio, outside Cincinnati. It is the legal successor to the original General Electric Company founded in 1892, which split into three separate companies between November 2021 and April 2024, adopting the trade name GE Aerospace after divesting its healthcare and energy divisions.[5][6]
GE Aerospace both manufactures engines under its name and partners with other manufacturers to produce engines. CFM International, the world's leading supplier of aircraft engines and GE's most successful partnership, is a 50/50 joint venture with the French company Safran Aircraft Engines. As of 2020, CFM International holds 39% of the world's commercial aircraft engine market share (while GE Aerospace itself holds a further 14%).[7] GE Aerospace's main competitors in the engine market are Pratt & Whitney and Rolls-Royce.
The division operated under the name of General Electric Aircraft Engines (GEAE) until September 2005, and as GE Aviation until July 2022. In July 2022, GE Aviation changed its name to GE Aerospace[8] in a move executives say reflects the engine maker's intention to broaden its focus beyond aircraft engines. In April 2024, GE Aerospace became the only business line of the former General Electric conglomerate, after it had completed the divestiture of GE HealthCare and GE Vernova (its energy businesses division).[9]
History
Early efforts
General Electric had a long history in steam turbine work, dating back to the 1900s. In 1903 they hired
This work made them the natural industrial partner to develop
Early jet engine work took place at GE's Syracuse, New York, (steam turbine) and
Military and civilian expansion
These changes in fortune led to debate within the company about carrying on in the aircraft engine market. However, the engineers at Lynn pressed ahead with the development of a new engine, the TG-180, which was designated J35 by the US military.[13]
Development funds were allotted in 1946 for a more powerful version of the same design, the TG-190. This engine finally emerged as the famed
Starting in 1961, General Electric started one of their most important research and development efforts, the GE1 technology demonstrator (originally designated the X101). The GE1 was a basic gas generator (compressor, combustor and turbine) onto which a variety of components such as fans, afterburners or other thrust vectoring devices could be added later. The design incorporated technologies such as a scaled compressor with variable stator vanes, an annual combustor, turbine-cooling advancements, and new materials for several government research programs. The US Government initially supported development of the GE1 to produce the J97 engine. The GE1 design and technology helped General Electric produce a range of engines, including the GE1/6 turbofan demonstrator for the TF39 engine the GE4 for the Boeing 2707 supersonic airliner, and the GE9 engine for the USAF's Advanced Manned Strategic Aircraft, later GE F101 engines for the B-1 bomber.:[14][15] The General Electric F101 was later developed into the General Electric F110 and CFM International CFM56 engines.
The
Another military-to-civilian success followed when GE was selected to supply engines for the
In the early 1970s, GE was also selected to develop a modern turboshaft engine for helicopter use, the T700. It has been further developed as the CT7 turboprop engine for regional transports.
Commercial aviation powerplants
In 1974 GE entered into an agreement with
The success of the CFM led GE to join in several similar partnerships, including Garrett AiResearch for the CFE CFE738, Pratt & Whitney on the Engine Alliance GP7000, and, more recently, Honda for the GE Honda Aero Engines small turbofan project. GE also continued the development of its own lines, introducing new civilian models like the GE90, and military designs like the General Electric F110.
GE Aerospace today
GE and competitor Rolls-Royce were selected by Boeing to power its new 787. GE Aviation's offering is the GEnx, a development of the GE90. The engine was also the exclusive power plant on the Boeing 747-8.
The Lynn facility continues to assemble jet engines for the
The Evendale plant conducts final assembly for the CFM International's CFM56, CF6, as well as LM6000, and LM2500 power plants.
The Durham, North Carolina, facility conducts final assembly for the CFM LEAP, GEnx, CFM56, GE90, GP7200, and CF34 power plants.
Crucial parts for these engines are crafted in secondary GE Aviation facilities, such as those in
Along with the purchase of Smiths Aerospace, the purchase included opening the first University Development Center at Michigan Technological University in Houghton, Michigan, in the effort to work with engineering students to provide training in engineering and software development. The program has performed well and GE Aviation has announced further UDC openings at Kansas State University. In July 2008, governments in the
On December 23, 2012, GE announced that it has agreed to purchase the aeronautical division of Avio, an Italy-based manufacturer of aviation propulsion components and systems for civil and military aircraft, for $4.3 billion U.S. (EUR3.3 billion).[25]
GE Aviation follows through to develop a
On July 18, 2022, GE announced that GE Aviation had been renamed "GE Aerospace",[8] and would become the successor to the GE company once the spinoffs of its subsidiaries are completed. GE Aerospace will own the GE trademark and logo, and will license the brand to the other companies, GE HealthCare and GE Vernova.[27]
Additive manufacturing
Recently, they have started incorporating 3D printing technologies in their engines and have incorporated the manufacturing process in the newly designed GE9X, the largest jet engine in the world.[28]
