Composite fan blades: The increasing bypass ration for more efficient motors will inevitably increase the blade size and weight. Rolls-Royce has started manufacture of the world’s largest fan blades, for its UltraFan ® demonstrator engine that will set new standards in efficiency and sustainability. Since the PD-35 engine is still at the research and development stage, the fan demonstrator was scaled down to fit the smaller PD-14 engine, on which it was tested, Inozemtsev explains. Access important shareholder information. The three-dimensional braided composites, with intertwined fiber bundles in the through-thickness direction, have advantages of high interlaminar shear strength, fracture toughness, and excellent impact resistance, making them a promising material for applications in the field of aeroengine fan blades.

The fan blades and fan cases being made at the facility are a feature of the Rolls-Royce UltraFan engine demonstrator, a new engine design which will reduce fuel burn and CO2 by at least 25% compared to the first Trent engine. Safran and Albany inaugurate third composite fan blade production plant for LEAP engine, in Mexico Querétaro (Mexico), February 21, 2018 Safran and Albany inaugurated today, in Mexico, a third joint manufacturing plant to make composite parts for the LEAP aircraft engine. The fan blades feature steel leading edges and glass-fibre trailing edges to better absorb bird impacts with more flexibility than carbon fiber. The investment needed to add this capability will start this year, with delivery of the first parts expected in January 2019. … GIF credit: Adam Senatori /GE Reports Where the GE90 has 22 blades and the GEnx holds 18, the GE9X will have only 16, even though it is the largest engine of the three. The material allowed GE engineers to design blades that result in lighter and more efficient engines, allowing airlines to save fuel by shedding precious pounds. �?
