TECHNICAL DEFINITION

The Pratt & Whitney XA103 is an adaptive, three-stream variable cycle turbofan engine developed under the U.S. Air Force's Adaptive Engine Transition Program (AETP), engineered to deliver enhanced fuel efficiency, increased thrust, and superior thermal management for next-generation combat aircraft and potential upgrades to platforms like the F-35.

BACKGROUND

The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from 37,000 to 43,000 lbf. Built by Pratt & Whitney, they were designed for the Boeing 757. As a 757 powerplant, these engines compete with the Rolls-Royce RB211.
