The “Affinity” engine is optimized with proven GE technology for supersonic flight and timed to meet the Aerion AS2 launch. GE Aviation and Aerion jointly are developing the first engine in more than half a century to power a civil supersonic aircraft. Thrust will be reduced at takeoff to meet Chapter 5 noise regulations, requiring a longer balanced field takeoff as an acceptable compromise. [7], The high-pressure core is derived from the nine-stage compressor and single-stage turbine of the CFM56, matched to a new low-pressure section optimised for supersonic speed with a 133 cm (52in) diameter fan instead of the 155-173 cm (61-68.3in) fan of the 6:1 bypass ratio CFM56. 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 final engine configuration is a core with billions of operational hours – suggesting the CFM56 – and a new low-pressure section optimised for supersonic speed. 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. “GE Aviation has more than 60 years of experience in designing and building engines adapted for supersonic aircraft. Affinity is a new engine which will be launched by GE and will have an exceptional performance for subsonic and supersonic flights. 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. In February 2018, Aerion released the GE engine configuration. • Efficient performance throughout the full flight envelope with a high-altitude service ceiling of … The GE9X is a lot bigger than a 747's existing engines. It is purposefully designed to enable efficient supersonic flight over water and efficient subsonic flight over land, without requiring modifications to existing compliance regulations. In this video, GE showcases its initial design of the first-ever supersonic engine purpose-built for business jets. 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 Aviation has a global service network to support these offerings. GE’s Affinity™ is a new class of medium bypass ratio engines that provide exceptional and balanced performance across supersonic and subsonic flights. The GE Affinity engine line, a new class of medium bypass ratio engines, has yet to mature – and may see advantages from the company’s use of Dassault Systèmes digital thread platform. 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 initial design of its Affinity medium-bypass-ratio turbofan was completed by October 2018. Its new Affinity engine, GE Aviation refers to power plants with an average degree of bypass. Affinity Up Close Among the Affinity’s features is a high-altitude 60,000-foot (18,288-meter) service ceiling, the highest bypass ratio of any supersonic engine, a special non-augmented supersonic exhaust system, an engine core adapted from GE’s commercial airline portfolio, and GE’s additive design and manufacturing technologies that optimize weight and performance.
