GE XA102 adaptive cycle engine completes design review

GE Aerospace has announced the successful completion of the Detailed Design Review (DDR) for its XA102 adaptive cycle engine, marking a critical milestone for the US Air Force’s Next Generation Adaptive Propulsion (NGAP) programme.

With the DDR completed, GE Aerospace has been awarded the next contract phase, which involves procuring, assembling, and testing a full-scale demonstrator of the XA102 engine.

This achievement is particularly significant as the XA102 is the first engine in GE Aerospace’s history to be developed using model-based systems engineering (MBSE). This approach represents a transformative shift in the design and testing of advanced propulsion systems. During the design review, GE Aerospace presented a comprehensive digital engine model to USAF, validating its readiness for the next development phase.

Dr. Steve “Doogie” Russell, vice president and general manager of Edison Works at GE Aerospace, highlighted the importance of this milestone: “GE Aerospace is making great strides with model-based engineering, which has been instrumental in the success of the XA102 engine design. As we transition into the procurement and build phase, we will continue to incorporate this innovative approach while working closely with our supply chain partners to advance the engine toward a full-scale demonstration.”

Adaptive cycle engines, like the XA102, are crucial for ensuring U.S. combat aircraft maintain their superiority. These engines provide up to 30% greater range and significantly improved thermal management capabilities compared to the most advanced combat engines available today.

The NGAP programme is focused on advancing technologies and manufacturing capabilities essential for air superiority in future contested combat environments. These advancements will enable next-generation fighter aircraft to achieve improved range, survivability, and thermal management capabilities for advanced weapons and sensors.

GE Aerospace’s leadership in adaptive cycle technology is built on over 100 years of innovation and partnership with the U.S. military. The XA100 engine, a predecessor to the XA102, completed multiple successful rounds of testing, maturing adaptive engine technologies. The XA102 engine represents the next evolution of propulsion, delivering enhanced capability while maintaining a focus on affordability and sustainability.
