GE Aviation began testing its engine core for the ADaptive Versatile ENgine Technology (ADVENT) program with the U.S. Air Force Research Laboratory. The core test demonstrates GE’s most advanced core propulsion technologies including lightweight, heat-resistant ceramic matrix composite (CMC) materials. These core technologies, along with an adaptive low pressure spool, will result in a 25% improvement in fuel efficiency, a 30% increase in operating range and a 5-10% improvement in thrust compared to today’s fixed-cycle engines. The ADVENT program is scheduled to conclude in 2013 with a full engine test. GE will continue to mature the ADVENT technologies through the Air Force’s Adaptive Engine Technology Development (AETD) program, which will conclude in 2016 following fan rig testing and a core engine test.
