VIRTUAL TURBOMACHINE BLADE CONTACT GAP INSPECTION

A system and method for virtually inspecting contact gaps of a blade stage (154) of a turbomachine is disclosed. The system may include a digitizing device (130) for obtaining a three-dimensional model (132) of a shroud (134, 152) of each blade (140) of the blade stage (154). A computer system may i...

More Information
Summary:A system and method for virtually inspecting contact gaps of a blade stage (154) of a turbomachine is disclosed. The system may include a digitizing device (130) for obtaining a three-dimensional model (132) of a shroud (134, 152) of each blade (140) of the blade stage (154). A computer system may include at least one module (124) configured to perform the following steps: extracting a geometric location data of a hard place plane of each shroud (134, 152) from the three-dimensional model (132); generating a three-dimensional virtual rendering (150) of the shrouds (134, 152) of the blade stage (154) based on the geometric location data and the known dimensions of the blade stage (154), the three-dimensional virtual rendering (150) including a rendering of contact gaps between adjacent shrouds (134, 152); and inspecting the blade stage (154) using the three-dimensional virtual rendering (150).
