APPARATUS FOR FABRICATING ROTOR ASSEMBLY

PROBLEM TO BE SOLVED: To provide a rotor assembly capable of reducing a high load in the radial direction and an influence of a vibration response of an airfoil caused by a dynamic response of a blade when the tip of the airfoil hits against an abrasive casing and friction is generated. SOLUTION: Th...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rotor assembly capable of reducing a high load in the radial direction and an influence of a vibration response of an airfoil caused by a dynamic response of a blade when the tip of the airfoil hits against an abrasive casing and friction is generated. SOLUTION: The airfoil 42 includes: a first sidewall 44; a second sidewall 46 connected to the first sidewall at a leading edge 48 and a trailing edge 50; a root 54; and an end 60 obliquely extending between the first and second sidewalls by forming an angle facilitating the reduction of a load in the radial direction generated to the airfoil during end friction.
