SYSTEMS AND METHODS FOR THROAT INSPECTION

Abstract:

A method includes generating inspection requirements for a radial section of a turbine nozzle by generating a resultant curve along the radial section and along a vane of the turbine nozzle, generating a middle inspection point along the resultant curve at a nominal throat location, generating first and second arrays of inspection points on sides of the middle inspection point along the resultant curve, generating a middle inspection vector normal to the middle inspection point, and generating first and second arrays of inspection vectors parallel to the middle inspection vector that intersect the resultant curve at the first and second arrays of inspection points, respectively. The inspection requirements include the middle inspection point, the middle inspection vector, the first and second arrays of inspection points, and the first and second arrays of inspection vectors. The method also includes generating a coordinate measuring machine (CMM) output file including the inspection requirements.
