As supersonic aircraft designer Aerion ceased operations over a lack of available funding, GE Aviation has confirmed that it has discontinued development work on the twin-shaft, medium-bypass Affinity engine that was to have powered the Mach 1.4 Aerion AS2 business jet. GE Aviation also noted that it is redeploying its Affinity team to other programs.
The engine-maker announced plans in October 2018 to move forward with the Affinity for the AS2, saying it would be designed using a “proven engine core adapted from GE’s commercial airline portfolio” with the latest technology full authority digital engine control, an advanced twin-fan, durable combustor, and advanced acoustic technology that would meet or exceed regulatory requirements.
