Abstract
Traversable strain sensor readers for reading a plurality strain sensor reference features on a turbine component include a traversing system configured to traverse the traversable strain sensor reader along at least a portion of the turbine component, and a reader configured to read at least a portion of the plurality of strain sensor reference features while the traversing system traverses the traversable strain sensor reader along at least the portion of the turbine component.
Claims18
A traversable strain sensor reference feature reader for reading a plurality strain sensor reference features disposed on a component, the traversable strain sensor reader comprising:
- a traversing system configured to traverse the traversable strain sensor reader along at least a portion of the component;
- and a reader configured to read at least a portion of the plurality of strain sensor reference features while the traversing system traverses the traversable strain sensor reader along at least the portion of the component;
- wherein the traversing system comprises:
- a set of wheels with one or more wheels that contact a first surface of the turbine component, and one or more wheels that contact a second surface of the turbine component.
A method for determining strain on a turbine component:
- providing a turbine component comprising a plurality of strain sensor reference features disposed along a turbine component separated from one another by a plurality of first distances at a first time;
- traversing a traversable strain sensor reader along at least an edge portion of the turbine component at a second time to read the plurality of strain sensor reference features separated from one another by a plurality of second distances at the second time;
- and, comparing the plurality of second distances to the plurality of first distances to determine a plurality of non-linear strain measurements of the turbine component between the plurality of strain sensor reference features;
- setting location values from the first measurement time to position the traversable strain sensor reader at a correct initial starting position for the second measurement time.
