GE Aviation plans to invest $27m and add up to 70 new jobs over the next five years at its Newark, Delaware facility. The facility manufactures advanced aircraft engine components made of ceramic matrix composites (CMCs). The investment will enable GE to develop a ‘Lean Lab’ at the site, allowing for collaboration between engineering and manufacturing. Production technologies for CMC components will be developed and verified in Newark prior to transitioning to manufacturing facilities for mass production. CMCs aim to improve fuel efficiency, lower emissions and improve environmental performance in aircraft engines by allowing them to run at higher temperatures.
