  • Method for checking the mechanical integrity of stabilizing elements on the rotor blades of a turbine and scanning device for implementing the method
    Patent number: 8844360
    Abstract: A method for checking a mechanical integrity of at least two stabilizing elements includes providing the at least two stabilizing elements that mechanically interconnect blade airfoils of rotor blades of a turbine in a circumferential direction of the turbine in an installed state of the turbine. The at least two stabilizing elements are adjacent to one another and inter-engage to form an engagement section having a material volume of the at least two stabilizing elements in the engagement section. The material volume of the at least two stabilizing elements is scanned, in an automated manner using ultrasound, so as to determine whether cracks are present. The scanning is performed from an outside of the at least two stabilizing elements.
