Based on technology already well established in existing civil aircraft, the Affinity engine has been developed specifically for the Aerion AS2, a supersonic business jet … [6] It has the highest bypass ratio for a supersonic engine which means GE’s Affinity … The coatings minimize interaction with combustion gases, further protecting components inside the engine. The General Electric T64 is a free-turbine turboshaft engine that was originally developed for use on helicopters, but which was later used on fixed-wing aircraft as well. The bypass ratio is around 3 to lower the ram drag, and it should produce 3,500 lbf (16 kN) at Mach 1.4 and FL500, with a cruise fuel consumption increased by 50% over the Mach 0.78 CFM56-5. GE describes the Affinity as a “twin-shaft, twin-fan turbofan with next-generation full authority digital engine control (Fadec).” The company said the engine is … [2], GE Aviation needs to develop a configuration accommodating reasonably well requirements for supersonic speed, subsonic speed and noise levels. GE claims Affinity will have an operational ceiling of 60,000 feet and the highest bypass ratio of any supersonic engine. It features a proven engine core with billions of hours of service, a durable combustor with advanced coatings for sustained high-speed operation, and a special, non-augmented supersonic exhaust system. The final engine configuration is a core with billions of operational hours – suggesting the CFM56 – and a new low-pressure section optimised for supersonic speed. [2] The Affinity engine is built on technologies proven and refined from GE’s unrivaled commercial engine core expertise. It will be used on the company’s 12-passenger AS2 business jet. GE’s New Affinity Engine: The Future of Supersonic Air Travel admin April 12, 2019 Airplanes , Jet Charters A new engine from GE will be the latest, surpassing supersonic flight—traveling at a speed greater than sound (approximately 768 miles per hour)—and making more progress than the last 55 years according to some. GE’s Affinity™ is a new class of medium bypass ratio engines that provide exceptional and balanced performance across supersonic and subsonic flights. Acoustically treated throughout, the Affinity is designed to meet or exceed regulatory requirements. The General Electric F110 is an afterburning turbofan jet engine produced by GE Aviation.The F110 engine uses the same engine core design as the General Electric F101.The F118 is a non-afterburning variant. GE just introduced a new engine, the Affinity, for the Aerion AS2 supersonic business jet as the first new supersonic engine in more than 55 years. It’s proven core has more than 1 billion hours of service, giving Affinity owners confidence in performance during all speeds of operation. Its mach plus-enabling power is combined with the reliability of our best commercial engines. Why GE’s Affinity Is a Supersonic Enabler, A new engine could bring back supersonic air-travel, Aerion Unveils Stage 5 GE Affinity Engine for Supersonic AS2. GE s’organise autour d’un échange mondial de connaissance, le « GE Store » (offre de produits GE), au sein duquel chaque activité partage et a accès aux mêmes technologies, marchés, structures et intelligences. This is the first time production F-15s will be powered by a GE engine, since all previous F-15 models were powered by Pratt and Whitney. The Affinity engine will be used in the upcoming Aerion AS2 supersonic business jet and GE says it will operate at altitudes of up to 60,000ft (18,000m) and speeds of Mach 1.4 - 1,000mph (1,600kmh) GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. At the May 2017 EBACE, Aerion announced its selection of GE Aviation to power the Aerion AS2 supersonic business jet. GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. The initial design of its Affinity medium-bypass-ratio turbofan was completed by October 2018. La firme possède 36 filiales dans plus de 150 pays et est une valeur symbole du New York Stock Exchange. The Affinity is a twin-shaft, twin-fan turbofan that is designed specifically for supersonic applications. Anticipated to be part of a family in the 16,000- to 20,000-pound-thrust range, the GE Affinity engine will be certified to operate at altitudes up to … Performance throughout the flight envelope with a high-altitude service ceiling of 60,000 feet. The Affinity engine will be used in the upcoming Aerion AS2 supersonic business jet and GE says it will operate at altitudes of up to 60,000ft (18,000m) and speeds of Mach 1.4 - … Get an inside look at the makings of an engine capable of speeds faster than 768 mph, beyond the speed of sound. Features of the Affinity engine Affinity is a new engine which will be launched by GE and will have an exceptional performance for subsonic and supersonic flights. While Boom has selected and tested the engine for the XB-1, the General Electric J85-15, the engine for Overture is yet to be selected. The GE27 was developed in the early 1980s under the "Modern Technology Demonstrator Engines" (MTDE) program sponsored by the United States Army Aviation Applied Technology Directorate. GE’s Affinity will be the first civil supersonic engine in 55 years. Preceded by fixed inlet guide vanes with movable flaps, the twin blisk fans have wide-chord titanium blades. GE’s Affinity™ is a new class of medium bypass ratio engines that provide exceptional and balanced performance across supersonic and subsonic flights. According to GE, Affinity is a twin-shaft, twin-fan turbofan controlled by a Full Authority Digital Engine Control (FADEC) system. GE then launched the Affinity program. Commentary: When GE tests a new engine, it mounts it on an old plane. ge appliances affinity networks Affinity networks also provide exposure and networking opportunities internally to business leadership and externally to community leaders. GE’s Affinity is a new class of medium bypass ratio engines designed to provide balanced performance across supersonic and subsonic flights. Launched in May 2017 to power the Aerion AS2 supersonic business jet, its initial design was completed in 2018 before its detailed design in 2020 for the first prototype production. GE’s Affinity™, the first civil supersonic engine in 55 years, will be able to operate as high as 60,000 feet and beat current emissions standards, including stringent noise requirements. In this video, GE showcases its initial design of the first-ever supersonic engine purpose-built for business jets. It has the highest bypass ratio ever for a supersonic engine, allowing fuel savings never seen before for supersonic travel while its blisk technology enable GE’s Affinity to comply to all environmental noise standards. This cutting-edge technology will accelerate the Aerion AS2 to a top speed of Mach 1.4, enabling efficient, environmentally-compliant supersonic flight. … It is purposefully designed to enable efficient supersonic flight over water and efficient subsonic flight over land, without requiring modifications to existing compliance regulations.
