According to Pratt & Whitney, the assessment demonstrated the company’s integrated digital engineering capabilities as development advances toward engine assembly and testing. The XA103 engine is being developed for future U.S. Air Force platforms under the NGAP programme.
Jill Albertelli, president of Pratt & Whitney’s Military Engines business, said the milestone reflected the company’s investment in digital infrastructure and cooperation with the Air Force. “This milestone demonstrates Pratt & Whitney’s investment in digital infrastructure, showcasing seamlessly integrated digital capabilities and reinforcing our strong collaboration with the U.S. Air Force,” Albertelli said.
“As we move forward with assembling our engine for testing, our NGAP team is simultaneously developing novel digital validation tools,” she added. “The performance we expect this engine to deliver exceeds anything available today, reinforcing the critical importance of continuous improvement and stable investment in maintaining propulsion as a strategic competitive advantage.”
Pratt & Whitney said the XA103 features an adaptive engine design intended to improve survivability, fuel efficiency and thermal management. The company stated that the engine is also designed to provide enhanced power generation capabilities for next-generation combat aircraft.
According to the company, these capabilities are intended to help the U.S. Air Force meet future operational requirements and maintain air dominance. Pratt & Whitney added that its NGAP team is currently working with suppliers to procure components required for engine assembly.
The company expects assembly of the XA103 test engine to support testing activities planned for the late 2020s. Pratt & Whitney said the programme continues to progress alongside development of new digital validation tools and manufacturing processes.
