Component surface profile scans are performed to determine relative profile heights along a two-dimensional scan line generated by the profilometer. Three-dimensional profile information is obtained by translating the scan line across the surface. Real time profile information is gathered without physical contact, which is helpful for extracting off-line engineering information about component surface conditions, including surface spallation, perforation, and gaps between components. The system is capable of determining blade tip gap between a turbine blade tip and its opposing abradable surface in the turbine casing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for surface profile inspection of off-line industrial gas turbines and other power generation machinery","description":"Internal components of power generation machines, such as gas or steam turbines, are inspected with a laser profilometer inspection system that is inserted and positioned within the turbine, for examp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9709463","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
