Abstract: Producing a component having an in use gas washed surface includes: obtaining a reference component having a reference shape with an in use gas washed surface; setting one or more performance threshold for the reference shape, the threshold defining an acceptable performance for the reference shape; obtaining a manufactured component made to the reference shape; measuring the manufactured component and determining a displacement distribution indicative of the geometric deviation of the manufactured component from the reference shape; determining a performance sensitivity distribution for the reference component, the sensitivity distribution having a plurality of points, each point indicative of a performance factor for the reference component; combining the sensitivity distribution and displacement distribution to determine a performance prediction for the manufactured component; determining whether the performance prediction is within the performance threshold; accepting or rejecting the component for use if the predicted performance is within or outside the performance threshold, respectively.

Abstract: A method of producing a component having an in use gas washed surface, including: obtaining a reference-component having a reference shape with in use gas washed surface; determining performance-sensitivity-distribution for the reference-component, the performance-sensitivity-distribution having plurality of points, each point indicative of a performance factor for the reference-component; identifying plurality of zones on the reference-component performance-sensitivity-distribution, each zone including at least one plurality of points; setting geometric-tolerance for each zone; manufacturing a component according to the reference-component; machining the manufactured-component outer surface so the manufactured-component surface is within predetermined geometric-tolerance for each reference-component corresponding zone; additionally/alternatively; measuring the manufactured-component geometry to determine whether the manufactured-component is within geometric-tolerance for each corresponding plurality of reference shape zones, and accepting production-component for use if geometry of the production-component is within the geometric-tolerance for each plurality of zones, or rejecting the production-component if the geometry is outside the geometric-tolerance for plurality of zones.
