Abstract
A method of supporting a cantilevered component mounted to a hub by locating a cassette in proximity to the cantilevered component, the cassette defining a volume for filling with an encapsulant; filling the volume with an encapsulant material; and causing the encapsulant to solidify to the cantilevered component to support the cantilevered component. The cantilevered component is preferably a blade on a bladed disc and the encapsulant provides support to change the vibration response of the blade during a subsequent machining step.
Claims17
A method of supporting a blade mounted on a hub, the method comprising:
- locating a cassette in proximity to the blade mounted on the hub, the cassette having a plurality of complementary alignment features and defining a volume for filling with an encapsulant material;
- filling the volume with the encapsulant material;
- solidifying the encapsulant material within the volume to support the blade on the hub;
- providing a sheet between the hub and the cassette for separating the hub from the volume, the sheet having a plurality of alignment features;
- and
- aligning the cassette to the hub by engaging the alignment features of the sheet with the complementary alignment features of the cassette.
