Abstract

Systems and methods for virtually inspecting contact clearances of blade (140) stages of a turbomachine are disclosed. The system may include digitizing means (130) for obtaining a three-dimensional model (132) of the casing (134, 152) of each blade (140) of the blade (140) stage. The computer system may comprise at least one module configured to perform the steps of: extracting from the three-dimensional model (132) geometric position data of a hard position plane of each sleeve (134, 152); to generate a three-dimensional virtual rendering (150) of the sleeve (134, 152) at the blade (140) level, the three-dimensional virtual rendering (150) including a rendering of the contact gap between adjacent sleeves (134, 152) ; and inspecting the blade ( 140 ) level using a three-dimensional virtual rendering ( 150 ).

Description

technical field [0001] The present disclosure relates generally to machine inspection, and more specifically to virtual turbine blade contact clearance inspection. Background technique [0002] In a turbine, blades are used to generate power from the flow of a working fluid. Specifically, a plurality of vanes may be coupled to the rotor such that flow of working fluid therefrom imparts rotational motion to the rotor. Turbine blades are initially shaped based on idealized models to create efficient blades. Each blade may include a shroud at its outer end that includes a hard surface that interacts with a mating hard surface of the shroud of an adjacent blade. Hardfaces are the portions of the sleeve that contain abrasive material and are in contact with each other at base load to damp vibration. During turbine engine operation, shrouded turbine blades are subject to substantial deformation and twisting. The contact gap between two adjacent blades is critical to ensure bla...
