39-523: T-stage is a British term for a compressor used in a particular concept for a variable cycle combat engine. The T-stage is part of the HP rotor in this concept. A US concept for a variable cycle combat engine also uses a similar compressor arrangement as part of the HP rotor. It is called a core driven fan stage (CDFS) by General Electric Aviation in their Variable Cycle Engine (VCE) which ran in 1981. Alternative concepts including an LP driven stage are shown in

78-419: A household in the village was $ 153,056, and the median income for a family was $ 169,125. About 2.7% of the population were living below the poverty line , including 3.2% of those under age 18 and 3.9% of those age 65 or over. About 56.4% of the population were employed, and 63.4% had a bachelor's degree or higher. As of the census of 2010, there were 2,767 people, 1,063 households, and 877 families living in

117-463: 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). General Electric had a long history in steam turbine work, dating back to the 1900s. In 1903 they hired Sanford Alexander Moss , who started

156-667: A new mid-sized turbofan, which emerged as the CFM56 . A 50/50 joint partnership was formed with a new plant in Evendale, OH to produce the design. At first, sales were very difficult to come by, and the project was due to be canceled. Only two weeks before this was to happen, in March 1979, several companies selected the CFM56 to re-engine their existing Douglas DC-8 fleets. By July 2010, CFM International had delivered their 21,000th engine of

195-505: A second manufacturing facility in Evendale, Ohio , near Cincinnati , was opened. J47 production ran to 30,000 engines by the time the lines closed down in 1956. Further development of the J47 by led to the J73 , and from there into the much more powerful J79 . The J79 was GE's second "hit", leading to a production run of 17,000 in several different countries. The GE and Lockheed team that developed

234-704: A small high-bypass engine using technologies from the TF39. The resulting TF34 was adapted to become the CF34 , whose wide variety of models powers many of the regional jets flying today. 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. In 1974 GE entered into an agreement with Snecma of France, forming CFM International to jointly produce

273-451: A turbine consisting of 300 components with one piece. The electron beam melting has good speed for economy, precision to reduce processing work, and size capability for larger parts; the hot process reduces stresses in the part and penetrates deeper than laser for thicker parts with coarser, cheaper metal powders . Additive techniques can be used across the engine and even in the over 1,500 °F (820 °C) hot section. They are used in

312-584: 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 Bromont, Quebec ; Hooksett, New Hampshire ; Wilmington, North Carolina ; Asheville, North Carolina ; Madisonville, Kentucky ; Rutland, Vermont ; and Muskegon, Michigan ; where the engine blades and vanes are manufactured. Smiths Group and General Electric announced on January 15, 2007, that

468-510: The General Electric F110 and CFM International CFM56 engines. The TF39 was the first high-bypass turbofan engine to enter production. Entered into the C-5 Galaxy contest in 1964 against similar designs from Curtiss-Wright and Pratt & Whitney , GE's entry was selected as the winner during the final down-select in 1965. This led to a civilian model, the CF6 , which was offered for

507-597: The I-A . GE quickly started production of improved versions; the I-16 ( J31 ) was produced in limited numbers starting in 1942, and the much more powerful I-40 (J33) followed in 1944, which went on to power the first US combat-capable jet fighters, the P-80 Shooting Star . Early jet engine work took place at GE's Syracuse, New York, (steam turbine) and Lynn, Massachusetts , (supercharger) plants, but soon concentrated at

546-715: The Lockheed L-1011 and McDonnell Douglas DC-10 projects. Although Lockheed later changed their engine to the Rolls-Royce RB211 , the DC-10 continued with the CF6, and this success led to widespread sales on many large aircraft including the Boeing 747 . Another military-to-civilian success followed when GE was selected to supply engines for the S-3 Viking and Fairchild Republic A-10 Thunderbolt II , developing

585-495: The Persian Gulf reached agreements with GE to expand engine maintenance operations there. The Wall Street Journal reported that Mubadala Development Company , which owns Abu Dhabi Aircraft Technologies, an overhaul, and maintenance company, signed an agreement worth an estimated $ 8 billion with GE; Abu Dhabi Aircraft Technologies will maintain and overhaul GE engines used in commercial aircraft purchased by airlines based in

624-715: The CFM56 family, with an ongoing production rate of 1250 per year, against a four-year production backlog. 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

663-802: 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.: The General Electric F101 was later developed into

702-618: The J79 and the F-104 Mach 2 fighter aircraft received the 1958 Collier Trophy for outstanding technical achievement in aviation. Other successes followed, including the T58 and T64 turboshaft engines, the J85 turbojet, and F404 turbofan. Starting in 1961, General Electric started one of their most important research and development efforts, the GE1 technology demonstrator (originally designated

741-722: The Lynn plants. On 31 July 1945 the Lynn plant became the "Aircraft Gas Turbine Division". GE was repeatedly unable to deliver enough engines for Army and Navy demand, and production of the I-40 (now known as the J33 ) was also handed to Allison Engines in 1944. After the war ended, the Army canceled its orders for GE-built J33s and turned the entire production over to Allison, and the Syracuse plant closed. These changes in fortune led to debate within

780-637: The Persian Gulf. 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). GE Aviation follows through to develop a supersonic engine concept for Aerion with a configuration accommodating reasonably well requirements for supersonic speed, subsonic speed and noise levels. On July 18, 2022, GE announced that GE Aviation had been renamed "GE Aerospace", and would become

819-543: The US patent "Variable Cycle Gas Turbine Engines" filed in 1975.

The per capita income for

975-532: 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. 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 General Electric J47 , which saw a great demand for several military aircraft;

1014-414: The development of turbosuperchargers at GE. This led to a series of record-breaking flights over the next ten years. At first, the role of the high-altitude flight was limited, but in the years immediately prior to WWII they became standard equipment on practically all military aircraft. GE was a world leader in this technology; most other firms concentrated on the mechanically simpler supercharger driven by

1053-517: The engine itself, while GE had spent considerable effort developing the exhaust-driven turbo system that offered higher performance. This work made them the natural industrial partner to develop jet engines when Frank Whittle 's W.1 engine was demonstrated to Hap Arnold in 1941. A production license was arranged in September, and several of the existing W.1 test engines shipped to the US for study, where they were converted to US manufacture as

1092-599: The former was divesting Smiths Aerospace to the latter for £ 2.4 billion ( US$  4.8 billion). GE Aviation closed the transaction on May 4, 2007. Smiths Aerospace, which was an important supplier, became an operating subsidiary of GE Aviation known as GE Aviation Systems . This acquisition will reportedly give the combined unit the clout to resist pricing pressures from its two largest customers, Boeing and Airbus . Analysts further assert that it enables General Electric to acquire assets similar to those it desired in its failed bid for Honeywell in 2000. Along with
