GE Aviation Demonstrates Highest Core Temperatures

GE Aviation completes testing its engine core for the ADaptive Versatile ENgine Technology (ADVENT) program with the U.S. Air Force Research Laboratory.

GE Aviation has completed testing its engine core for the ADaptive Versatile ENgine Technology (ADVENT) program with the U.S. Air Force Research Laboratory on February 6, 2013, achieving the highest combination of compressor and turbine temperatures ever recorded in aviation history.

The accomplishment is a result of 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, result in a 25% improvement in fuel efficiency, a 30% increase in operating range and a 5% to 10% improvement in thrust compared to today’s fixed-cycle engines.

The ADVENT program is scheduled to conclude this year 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.

The core test began on October 4, 2012, and included 16 test periods and more than 60 operating hours focused on reaching the demonstration point, which occurred on February 6, 2013. In reaching the demonstration conditions, the GE ADVENT core achieved the highest combination of compressor and turbine temperatures ever achieved in the aviation industry. This successful test not only lays the foundation for the full engine testing planned later this year, it also provides proof of a solid advanced technology suite for the AETD program and the expected follow-on programs.

"We couldn't be happier with the ADVENT core testing results, which validate the technology choices that will enable the Air Force to meet the aggressive performance targets required for future missions," says Jeff Martin, GE Aviation’s general manager for advanced programs. “GE Aviation is honored to partner with the Air Force in the demonstration of these unique technologies.”

“This is a critical milestone that gives us great confidence as we prepare for the full engine test in ADVENT later this year and move forward on the design of the AETD engine,” says Dan McCormick, GE Aviation’s general manager for the ADVENT & AETD programs. “We’ll integrate these proven ADVENT technologies into our AETD engine, along with advanced controls and exhaust system designs.”

GE Aviation also completed the Initial Design Review milestone for the AETD program with the Air Force on February 8, 2013.  This milestone marks the point at which the team is ready to progress through preliminary design of the engine on the path to the Preliminary Design Review milestone scheduled for November 2014.
