Abstract: An angled face cap probe includes a housing having a radially inner end and a radially outer end, defining a cavity, and configured to be located radially outward from an airfoil. The angled face cap probe further includes a sensor located in the cavity at the radially inner end of the housing, having a sensor body with a sensing face that is angled to match or substantially match an angle of a radially outward face the airfoil, and having a sensor flat that is elongated in a first direction. The angled face cap probe further includes an outer cap located in the cavity, coupled to the housing, and having an outer cap main body and cap legs that extend radially inward from the outer cap main body to interface with the sensor flat to resist rotation of the sensor relative to the housing.

Abstract: A low profile un-lensed non-intrusive stress measurement system probe may comprise a housing comprising a first channel and an optical face, a first hypotube disposed within the first channel and coupled at a sensing aperture in the optical face, and a plurality of optical fibers disposed within the first hypotube, wherein the first hypotube executes a bend between 45° and 90° within the housing.
