GE Aviation's adaptive cycle engine test exceeds expectations

GE Aviation’s adaptive cycle engine core test exceeded target temperatures by more than 130 degrees Fahrenheit, demonstrating the highest combination of compressor and turbine temperatures ever recorded in aviation history. Based on the successful core test’s proof of the durability of the hardware, the first full adaptive cycle engine test is scheduled for the fourth quarter of 2013 in cooperation with the U.S. Air Force Research Laboratory (AFRL). GE’s adaptive cycle engine integrates proven commercial engine technologies: the next-generation LEAP* high-pressure compressor; heat-resistant ceramic matrix composites (CMCs) in the combustor and high-pressure turbine; and additive manufactured components that result in a 25% improvement in fuel efficiency, a 30% increase in aircraft operating range and a five-to-10% improvement in thrust compared to today’s most advanced military combat engines. Following completion of full engine testing in the Adaptive Versatile Engine Technology (ADVENT) program, GE will continue to mature its adaptive cycle technology through the Air Force’s Adaptive Engine Technology Development (AETD) program, which is scheduled to conclude in 2016 following fan rig testing and a core engine test.
