Title:
VIRTUAL TURBOMACHINE BLADE CONTACT GAP INSPECTION
Document Type and Number:
Japanese Patent JP2017078401
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a computer system and computerized method for virtually inspecting contact gaps of a blade stage of a turbomachine.SOLUTION: The system may include a digitizing device 130 for obtaining a three-dimensional model 132 of a shroud 134 of each blade of the blade stage. A computer system may include at least one module configured to perform the following steps: extracting a geometric location data of a hard face plane of each shroud from the three-dimensional model; generating a three-dimensional virtual rendering of the shrouds of the blade stage on the basis of the geometric location data and known dimensions of the blade stage, the three-dimensional virtual rendering including a rendering of contact gaps between adjacent shrouds; and inspecting the blade stage using the three-dimensional virtual rendering.SELECTED DRAWING: Figure 1
