Pratt & Whitney has successfully completed the detailed design review of its Next-Generation Adaptive Propulsion system in partnership with the United States Air Force.
This milestone was achieved using a fully digital evaluation process, allowing immediate access to critical data and expediting the transition to hardware procurement for the development of its XA103 prototype ground demonstrator, set to undergo testing in the late 2020s.
The Next-Generation Adaptive Propulsion (NGAP) program is a key component of the US Air Force’s Next Generation Air Dominance (NGAD) initiative, which is aimed at developing a sixth-generation air combat system to replace and surpass current platforms such as the F-22 Raptor. The NGAD program focuses on cutting-edge stealth technology, enhanced range, increased lethality, and advanced propulsion systems that integrate artificial intelligence and data-driven decision making for superior air combat capabilities.
“The significance of this first fully digital review cannot be understated,” said Jill Albertelli, president of Pratt & Whitney’s military engines business.
“Digital processes throughout the life cycle are crucial to rapidly and efficiently deliver advanced warfighter capabilities. As we celebrate our centennial, the digital tools and processes that our NGAP team has demonstrated, and will continue to advance, will be at the foundation of our technology maturation for our future next-gen solutions.”
Pratt & Whitney’s NGAP engine features an adaptive architecture, allowing its components to actively adjust for optimised fuel efficiency, survivability, and power and thermal management – capabilities that surpass those of fourth and fifth-generation engines. This innovation is expected to play a critical role in ensuring the US Air Force maintains air superiority amid evolving global security challenges.
The NGAD program is a multifaceted initiative that involves not only next-generation propulsion but also the development of new airframes, sensors and networked capabilities designed to provide a decisive advantage in future conflicts. As strategic competitors invest heavily in their own advanced air combat technologies, the US Air Force’s NGAD program, bolstered by Pratt & Whitney’s advancements, will be instrumental in maintaining a technological edge.
With this latest development, Pratt & Whitney continues to reinforce its legacy of delivering cutting-edge propulsion solutions that enhance operational effectiveness and national security. The successful digital review and subsequent transition to hardware procurement mark a significant step forward in the evolution of adaptive engine technology.
