Abstract
A method is disclosed herein. In various embodiments, the method comprises: coupling a sheath to an airfoil of an integrally bladed rotor, the sheath comprising a plurality of apertures disposed therein; and coupling a plurality of locators to the integrally bladed rotor, each locator in the plurality of locators disposed through a corresponding aperture in the plurality of apertures.

A method comprising,
- coupling a sheath to an airfoil of an integrally bladed rotor, the sheath comprising a plurality of apertures disposed therein;
- and
- coupling a plurality of locators to the integrally bladed rotor, each locator in the plurality of locators disposed through a corresponding aperture in the plurality of apertures.
An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising:
- commanding, via the processor, a scanner to scan around a first airfoil of a bladed rotor;
- determining, via the processor, an apex of each locator in a plurality of locators associated with the first airfoil;
- and
- generating, via the processor, a first six point nest of the airfoil based on the apex of each locator in the plurality of locators.
A sheath, comprising:
- a first protrusion, a second protrusion and a third protrusion extending from a first surface, the first protrusion, the second protrusion, and the third protrusion configured to contact a pressure side or a suction side of an airfoil in response to coupling the sheath to the airfoil;
- a first edge roll and a second edge roll configured to contact a leading edge or a trailing edge of the airfoil in response to coupling the sheath to an airfoil;
- and
- a fourth protrusion configured to extend outward from the sheath and contact a platform of a rotor in response to couple the sheath to the airfoil.
