Engine technology advances might achieve a 10% reduction over today’s CFM LEAP and Pratt & Whitney Geared TurboFan engines. So, advanced design and production is key to the business case for the NBA.
Despite using these advancements on Boeing defense programs (the T-7 Red Hawk trainer and MQ-25 unmanned aerial refueling airplane), assimilating them into commercial airplane development and production has high hurdles.
Boeing has had mixed success using advanced technology design and production on its current commercial programs.
Regulatory approvals will be challenging.
Engines will be 10% better than the LEAP and GTF—but are these the correct comparisons?
