The General Electric Affinity was a turbofan that GE Aviation developed for supersonic transports. It was conceived in May 2017 to power the Aerion AS2 supersonic business jet, with initial design finished in 2018, and GE discontinued development in May 2021 after Aerion collapsed. Its high-pressure core was derived from the CFM56 and the F101 and F110 military engines, with a nine-stage compressor and single-stage turbine, matched to a new twin-fan low-pressure section with a 133 centimetre fan chosen for supersonic flight. The engine had a bypass ratio of about 3, no afterburner, a variable-area nozzle with a longitudinally moving cone, and an 18,000 pounds-force rating, and it was meant for Mach 1.4 to 1.6 cruise. Its cancellation left the Boom Overture without a supersonic engine supplier.
