Claims20
A vane guide assembly for a gas turbine engine, comprising:
- an airfoil having an end bonded to an opening of a platform by an adhesive;
- and
- a pull tab partially located in the adhesive and having a portion extending from a bondline formed by the adhesive.
A vane guide assembly for a gas turbine engine, comprising:
- an airfoil having a first end bonded to an opening of an outer diameter platform by an adhesive and a second end bonded to an opening of an inner diameter platform by an adhesive;
- a first pull tab partially located in the adhesive bonding the first end to the opening of the outer diameter platform, the first pull tab having a portion extending from a bondline formed by the adhesive bonding the first end to the opening of the outer diameter platform;
- and
- a second pull tab partially located in the adhesive bonding the second end to the opening of the inner diameter platform, the second pull tab having a portion extending from a bondline formed by the adhesive bonding the second end to the opening of the inner diameter platform.

A method for testing a bond between an end of an airfoil and a platform of a vane guide assembly, comprising:
- inserting a pull tab partially into a gap between an exterior surface of the end of the airfoil and an opening in the platform;
- injecting an adhesive into the gap;
- curing the adhesive in order to form the bond between the end of the airfoil and the platform of the vane guide assembly, wherein a portion of the pull tab extends from a bondline of the adhesive after it has cured;
- and
- pulling the portion of the pull tab until it either breaks or dislodges from the bondline.
