Engine manufacturer Pratt & Whitney will use new digital design technology to accelerate its work on the XA103, its submission for the U.S. Air Force’s Next Generation Adaptive Propulsion (NGAP) program.

Next Generation Adaptive Propulsion, or NGAP, calls for the development of adaptive cycle engines that can be reconfigured in flight between high performance and high efficiency modes by adjusting the engine’s bypass ratio. The winning design from the program is expected to eventually power the U.S. Air Force’s next generation fighter, the Boeing F-47, though with NGAP not expected to be finalised until 2030 there is a strong possibility that initial models will have to rely on an interim engine option.
