GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. The engine is designed to meet stringent … Commentary: When GE tests a new engine, it mounts it on an old plane. Managing the high intake temperatures at high altitudes is a key challenge for the initial design. [8] Since its founding as GE's first affinity network, AAF has expanded globally to provide members with development and networking opportunities while helping contribute to the growth of the company and volunteering in the communities where GE operates. This new engine class, revealed today as GE’s Affinity TM is optimized with proven GE technology for supersonic flight and timed to meet the Aerion AS2 launch. The engine is designed to meet stringent Stage 5 subsonic noise requirements and beat current emissions standards and, according to GE, the Affinity engine features: Efficient performance throughout the full flight envelope with a high-altitude service ceiling of 60,000. It is purposefully designed to enable efficient supersonic flight over water and efficient subsonic flight over land, without requiring modifications to existing compliance regulations. [2] GE’s Affinity™ is a new class of medium bypass ratio engines that provide exceptional and balanced performance across supersonic and subsonic flights. It lacks an afterburner, and has a combustor with advanced coatings and uses additive manufacturing technologies. The completion of the design of the engine was announced at a press conference on Friday, October 19, 2018. The CFM56 is derived from the B-1's GE F101. GE’s Affinity™ is a new class of medium bypass ratio engines that provide exceptional and balanced performance across supersonic and subsonic flights. The revolutionary new GE Adaptive Cycle Engine is the latest in a proud legacy of game-changing propulsion innovations from GE Aviation. The “Affinity” engine is optimized with proven GE technology for supersonic flight and timed to meet the Aerion AS2 launch. Called Affinity, the engines borrow from GE expertise in building jet engines for fighter planes and well as commercial engines for the latest generation passenger jets like Boeing 787 Dreamliner. It will be used on the company’s 12-passenger AS2 business jet. GE’s Catalyst turboprop is expected to fly on Textron Aviation's Cessna Denali next year. 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. GE Aviation this week provided a glimpse into design challenges that the company is working through as it progresses on the twin-shaft, medium-bypass Affinity engine selected to power the Aerion AS2 supersonic business jet. Its detailed design review should be completed by 2020 for the first prototype production. Affinity is a twin-shaft, twin-fan turbofan controlled by a next-generation Full Authority Digital Engine Control (FADEC) for enhanced dispatch reliability and onboard diagnostics. F110-GE-129 engines, with 29,400 lb f (131 kN) of thrust, power 40 F-15 fighters of South Korea. They are twin-shaft turbofans built around the core of an airline engine. The GE9X is a lot bigger than a 747's existing engines. 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. At the May 2017 EBACE, Aerion announced its selection of GE Aviation to power the Aerion AS2 supersonic business jet. ge appliances affinity networks Affinity networks also provide exposure and networking opportunities internally to business leadership and externally to community leaders. Affinity is a new engine which will be launched by GE and will have an exceptional performance for subsonic and supersonic flights. The engine is designed to meet stringent Stage 5 subsonic noise requirements and beat current emissions standards and long-term regulatory goals. It is optimised for supersonic flight over water and subsonic flight over land, and designed to meet Stage 5 subsonic noise requirements as well as current emissions standards. They act as a heat barrier to keep parts cooler, allowing the engine to run at higher temperatures for greater efficiencies. The engine employs design features and lessons learned from GE’s supersonic military engines while pulling features from GE’s Passport™ business jet engine GE’s Affinity … GE Affinity GE Aviation Briefing at NBAA 2018. GE Aviation has a global service network to support these offerings. GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. GE’s Affinity is a twin-shaft, twin-fan turbofan controlled by a next generation Full Authority Digital Engine Control (FADEC) for enhanced dispatch reliability and onboard diagnostics. GE claims that the Affinity, which is based on the company's supersonic fighter jet experience and lessons learned from building engines for the Boeing 787 Dreamliner, will be up to the job. 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’s Affinity: A new Supersonic Engine for Business Aviation The aviation industry hasn’t seen commercial supersonic transportation since the Concorde, that entered service in the 1970s. Its new Affinity engine, GE Aviation refers to power plants with an average degree of bypass. Durable combustors for hot and harsh conditions and advanced coatings for turbine section. GE’s Affinity is a new class of medium bypass ratio engines designed to provide balanced performance across supersonic and subsonic flights. We compare it to its donor engine, the CFM56. Its high-pressure core is derived from the CFM56, matched to a new twin fan low-pressure section for a reduced bypass ratio better suited to supersonic flight. Performance throughout the flight envelope with a high-altitude service ceiling of 60,000 feet. The General Electric Affinity is a turbofan developed by GE Aviation for supersonic transports. Preceded by fixed inlet guide vanes with movable flaps, the twin blisk fans have wide-chord titanium blades. The CFM56-5 sitting on an A320 has a cruise thrust of around 5,000lbf at 37,000ft, a bypass ratio of 5 and a fuel consumption of 0.6 lb/lbf/hr. 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. 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 … GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. The Affinity integrates a unique blend of proven military supersonic experience, commercial reliability and the most advanced business jet engine technologies. announced in October last year that it would be using the General Electric Affinity engine. Oct 20, 2018 - GE Aviation announced the initial design of its first supersonic engine Affinity built for business jets. [4] Before we look at Mach 2 engines, let’s start with comparing some key data for the GE Affinity, an engine optimized for a modest SST speed of Mach 1.4. 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.
