Abstract: An apparatus for monitoring the structural integrity of a component. A monitoring structure is applied to a component that is subject to structural degradation. The monitoring structure includes an electrical conductor that becomes cracked if the component becomes structurally degraded. When the component is a ductile metal component that may be degraded by bending, the electrical conductor is formed of a brittle material that cracks when the ductile metal component is bent. When the component is a brittle ceramic heat shield wherein a crack having a critical length is of concern, the electrical conductor is located at a predetermined location wherein a critical length crack in the component will propagate into the conductor. A crack in the electrical conductor is detected with a monitoring device to indicate a degraded structural condition in the component.

Abstract: The invention relates to an assembly that consists of a structural element and at least one control element for detecting degradation of said structural element. Said control element comprises an electroconducting control structure that is decoupled from a functionality of the structural element and that has a defined electrical property. The control structure and the structural element are firmly interlinked to such an extent that the degradation of the structural element effects a degradation of the control structure and thus a change of the defined electrical property of the control structure. The structural element is for example a ceramic heat shield of a combustion chamber of a gas turbine. The control structure consists of a brittle ceramic conductor material.
