Is designing a new generation of carbon fiber composite material using new composite materials "Micro Cooling Fan" blade, compared to the same engine, the use of this material will reduce fuel consumption by 5%. Performance of the engine fan blades produce and aviation technology combined with high-performance aircraft engines designed to maintain our competitive advantage in this area. "Micro Cooling Fan" carbon fiber composite materials continue to progress in this decade, which makes GE's engineers to design a thinner GE9X fan blades, its strength and composite materials we currently use"Micro Cooling Fan"blade fairly. Fewer, thinner blades will enhance airflow and fan lighter, more efficient, help to improve the overall GE9x engine performance and fuel efficiency.
