Abstract

Weight reduction of turbofan engines is one of the main concerns of aero engine manufacturers inorder to reduce fuel burn. To achieve higher fuel efficiency, aero engine manufacturers developturbofans with higher bypass ratio, which can only be achieved with larger (and heavier) fan sections.This makes weight reduction in fan components a major consideration and becomes a key driver forthe use of composite materials in future engines. The objective of this work is 3D design; performstructural analysis by using Ti-64 alloy. This composite alloy is used for two objective orientations,one is solid structure of Ti-64 alloy and another is to construct three layered fan blades with honeycomb core of bonding by Ti-64 alloy sheets. To achieve higher fuel efficiency the objective of thisproject is to 3D design; perform structural analysis on Ti-64 alloy. This work is about the structuralanalysis of a composite fan blade with solid and honeycomb sandwich construction. The cavity ofblade is filled by Ti-64 foil like a honey comb structure. The focus of this work is to design the fanblade with honeycomb core and conduct static, model, and dynamic analysis and come up with thebest suitability among solid and honeycomb structure for the turbo fan in aero engines.
