Abstract
An adjustable blade assembly for use in a rotary machine, such as a turbine or a compressor, wherein the airfoil is separable from the assembly at the blade platform. The airfoil is provided with a root which is seated within a complementary kerf formed within the platform. Each of the two sections is fabricated independently using standard machine tools, thereby eliminating the need of hand-forming, complex blade contours. In assembly, the airfoil is loosely supported within the platform whereby the stresses generated at resonant frequencies are highly damped.
