Abstract
An additively manufactured component is provided. The additively manufactured component includes an additively manufactured first part defining a first trench, an additively manufactured second part defining a second trench and a fiber optic sensor. The additively manufactured first and second parts are additively manufactured together with the first and second trenches corresponding in position such that the additively manufactured first and second parts form an assembled part with a fiber channel cooperatively defined by the first and second trenches. The fiber optic sensor includes a first sensor part embedded in the fiber channel and a second sensor part operably coupled to the first sensor part and extendible at an exterior of the assembled part.
Claims13
An additively manufactured component, comprising:
- an additively manufactured first part formed to define a first trench;
- an additively manufactured second part formed to define a second trench,
- the additively manufactured first and second parts being additively manufactured together with the first and second trenches corresponding in position such that the additively manufactured first and second parts cooperatively form an assembled part with a fiber channel cooperatively defined by the first and second trenches;
- and
- a fiber optic sensor comprising:
- a first sensor part embedded in the fiber channel and comprising an exterior surface and a thermal barrier coating (TBC) disposed on the exterior surface to contact with proximal portions of the first part in the first trench and proximal portions of the second part in the second trench;
- and
- a second sensor part operably coupled to the first sensor part and extendible at an exterior of the assembled part,
- wherein the TBC comprises a protruding surface feature and the fiber channel is defined by a corresponding one of the first and second trenches to include a recessed surface feature corresponding in position to the protruding surface feature.
A fiber optic sensor for operable disposition in a fiber channel of an additively manufactured component, the fiber optic sensor comprising:
- a first sensor part embedded in the fiber channel and comprising an exterior surface and a thermal barrier coating (TBC) disposed thereon to protect the exterior surface during additive manufacturing processes;
- a second sensor part operably coupled at a first end thereof to the first sensor part and extendible at an exterior of the assembled part;
- and
- a processing unit operably coupled to a second end of the second sensor part to process sensor readings obtained by the first part,
- wherein the TBC comprises a protruding surface feature that corresponds with a recessed surface feature of the fiber channel.
A fiber optic sensor for operable disposition in a fiber channel of an additively manufactured component, the fiber optic sensor comprising:
- a first sensor part embedded in the fiber channel and comprising an exterior surface and a thermal barrier coating (TBC) disposed thereon to protect the exterior surface during additive manufacturing processes;
- a second sensor part operably coupled at a first end thereof to the first sensor part and extendible at an exterior of the assembled part;
- and
- a processing unit operably coupled to a second end of the second sensor part to process sensor readings obtained by the first part,
- wherein the first sensor part and the TBC each have corresponding sections that are respectively embedded in first and second transverse components of the fiber channel.
