A system for coupling at least one component to a blade of a gas turbine engine includes a blade holder and an intensifier tool. The intensifier tool includes a plate configured to contact the component and a heating device coupled to the plate. The system further includes an adhesive layer disposed between the component and the blade, a pressure strip coupled to the plate and the blade that fully encloses the plate, and a pressure applicator coupled to the plate. The adhesive layer has a uniform bond thickness along a length of the component due to pressure applied by the pressure applicator. Upon being heated by the heating device, the adhesive layer is cured, thereby coupling the component to the blade.

A heating device includes: a heat generator configured to generate heat when supplied with electric power; a first insulator and a second insulator respectively layered on a front surface and a back surface of the heat generator and covering the heat generator; a first heat transfer body layered on the first insulator so as to cover the first insulator and a second heat transfer body layered on the second insulator and covering the second insulator; and a circumferential edge structure configured to seal circumferential edges of the first insulator and the second insulator. In the circumferential edge structure, the circumferential edges are sealed by direct or indirect joining of the first heat transfer body and the second heat transfer body.
