GE Aviation Completes ADVENT Engine Core Tests

GE Aviation has completed testing of its engine core for the Adaptive Versatile Engine Technology (ADVENT) programme with the US Air Force Research Laboratory. It achieved the highest combination of compressor and turbine temperatures recorded in aviation history, according to the manufacturer. As part of the programme, GE has used core propulsion technologies including lightweight, heat-resistant ceramic matric composite (CMC) materials. When combined with an adaptive low-pressure spool the core technologies result in a 25 per cent improvement in fuel efficiency; a 30 per cent increase in operating range and; a five to 10 per cent improvement in thrust when compared to a current fixed-cycle engine, according to GE. The ADVENT programme is scheduled to conclude this year with a full engine test, whilst GE continues to develop the ADVENT technologies through the Air Force’s Adaptive Engine Technology Development (AETD) programme, set to conclude in 2016.
