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. Durable combustors for hot and harsh conditions and advanced coatings for turbine section. The revolutionary new GE Adaptive Cycle Engine is the latest in a proud legacy of game-changing propulsion innovations from GE Aviation. The revolutionary new GE Adaptive Cycle Engine (ACE) is the latest in a proud legacy of game-changing propulsion innovations from GE Aviation. Top: The Aerion AS2 is designed to cut a trans-Atlantic flight by three hours and a … Thrust will be reduced at takeoff to meet Chapter 5 noise regulations, requiring a longer balanced field takeoff as an acceptable compromise. 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 Affinity’s high-pressure core optimizes the efficiencies of a proven commercial airline engine with the power of a military fighter engine. An engine for supersonic flight needs a lower bypass ratio than modern turbofans, having a higher flow speed for better efficiency. 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. A 747 has a fan with a diameter of 105 inches (8.75 feet). GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. Affinity is a twin-shaft, twin-fan turbofan controlled by a next-generation Full Authority Digital Engine Control (FADEC) for … GE then launched the Affinity program. It 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. Preceded by fixed inlet guide vanes with movable flaps, the twin blisk fans have wide-chord titanium blades. In this video, GE showcases its initial design of the first-ever supersonic engine purpose-built for business jets. The CFM56 is derived from the B-1's GE F101. Oct 20, 2018 - GE Aviation announced the initial design of its first supersonic engine Affinity built for business jets. [3] 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 engine is a revolution in aviation innovation. In February 2018, Aerion released the GE engine configuration. It is a unique blend of … Brad Mottier of GE Aviation briefed the media on the Catalyst Turboprop, Passport business jet engine, and announced the Affinity engine program for supersonic aircraft at NBAA 2018. 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 … GE’s Affinity will be the first civil supersonic engine in 55 years. 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. The twin-shaft, twin-fan engine with FADEC has a service ceiling of 18,300 m (60,000 ft). It is purposefully designed to enable efficient supersonic flight over water and efficient subsonic flight over land, without requiring modifications to existing compliance regulations. Managing the high intake temperatures at high altitudes is a key challenge for the initial design. GE’s Affinity engine is a revolution in aviation innovation. View the Adaptive Cycle. GE then launched the Affinity program. 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 … And airline engines its detailed design review should be completed by 2020 for the first engine.
