GE’s Affinity™ is a new class of medium bypass ratio engines that provide exceptional and balanced performance across supersonic and subsonic flights. 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.

GE’s Affinity integrates a unique blend of proven military supersonic experience, commercial reliability and the most advanced business jet engine technologies. 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.

It is purposefully designed to enable efficient supersonic flight over water and efficient subsonic flight over land, without requiring modifications to existing compliance regulations. The engine is designed to meet stringent Stage 5 subsonic noise requirements and beat current emissions standards and long-term regulatory goals.
