Abstract: A lost core mold component comprises a first leg and a second leg with a plurality of crossover members connecting the first and second legs. The plurality of crossover members includes outermost crossover members spaced from each other. Adjacent ends of each of the first and second legs, and second crossover members are spaced closer to each other than are the outermost crossover members. Central crossover members extend between the first and second leg and between the second crossover members. The outermost crossover members extend for a first cross-sectional area. The second crossover members extend for a second cross-sectional area and the central crossover members extend for a third cross-sectional area. The first cross-sectional area is greater than the second cross-sectional area. The second cross-sectional area is greater than the third cross-sectional area. A gas turbine engine and component are also disclosed.

Abstract: Systems and methods for depth measurement are described herein. A depth measurement device may comprise a first light source configured to direct a first beam of light, a second light source configured to direct a second beam of light, and a mirror. The mirror may be for viewing at least one of the first beam of light and the second beam of light. The depth measurement device may further comprise a housing. The depth measurement device may further comprise an eyepiece. The first beam of light and the second beam of light may be configured to intersect at a desired location. The eyepiece may be configured to maintain a consistent line-of-sight between the eyepiece, the mirror, and the desired location. In various embodiments, the second beam of light may be oriented at an acute angle with respect to the first beam of light.
