General Electric XA102

The General Electric XA102 is an American adaptive cycle engine demonstrator developed by General Electric. Under the United States Air Force Next Generation Adaptive Propulsion program it competes with the Pratt and Whitney XA103 to power the service sixth generation F-47 air superiority fighter, part of the Next Generation Air Dominance family of systems. It grew out of the XA100 work, but was optimized differently, with more emphasis on supersonic cruise. Like the XA100 it is a three-stream engine that can send air to a third bypass stream for efficiency and heat rejection, or back to the core and fan streams for thrust, and it uses ceramic matrix composites for higher turbine temperatures. The thrust has not been disclosed, though aviation reporters speculate the 35,000 pounds-force class. Critical design review was completed in December 2023.
