Efektivita měření Kaplanovy turbínové lopatky

Abstract

This bachelor’s thesis focuses on evaluating the efficiency of non‑contact measuring devices used for the inspection of a Kaplan turbine blade, a component with highly complex geometry. The theoretical part summarizes the principles of contact and non‑contact measurement methods and the factors influencing their accuracy and applicability. The experimental part compares the optical scanner ATOS Q and the portable laser scanner HandySCAN 700 when measuring the same turbine blades. ATOS Q provided data suitable for detailed analysis of functional surfaces and precise evaluation in defined cross‑sections, while HandySCAN was mainly applicable for an orientational assessment of the surface. The results show that for the inspection of geometrically complex turbine blades, an optical system based on structured‑light projection is the more effective solution.
