Rolls-Royce has begun manufacturing of the world’s largest composite fan blades, for its UltraFan demonstrator engine. “This design provides a three-dimensional aerodynamic fan system that helps achieve lower fuel burn in a high flow/high bypass engine that is lighter weight and has lower noise. Turbofans currently designed for the next generation of medium-haul airliners are constructed from composite materials with titanium shaped leading edges. Recently however, RR has anounced that it will make a switch to composite blades for … The shaft spins the fan blades at the front of the engine drawing in more air air and ensuring the process continues. The GE90 fan blade is the first ever composite fan blade in service on a commercial jet engine. Epoxy resin with carbon fiber is predominantly used material type for manufacturing composite fan blades. GKN took over Filton wing component and assemblies manufacturing unit and Filton-West is their new production plant making wing spars and trailing edge for A350. Subscribe. 3 Minute Read. RR, for the past 40 years has been using titanium fan blades (it's first attempt on the Rb211-22B resulted in bankruptcy). Our manufacturing capabilities include key technologies like forging, high-speed 5-axis machining, assembly and balancing of critical components. Further development of the composite material is necessary to allow composite blade designs to approximate the dimensions of a metallic fan blade. Post navigation Previous Post Next Post.
