Large Volume Metrology
The inspection of large objects calls for dedicated metrology solutions and technologies. We offer solutions for accurate and contactless inspection capabilities that are used within a wide variety of large volume measurement and inspection applications: aircraft fuselage section analysis, tool assembly and alignment inspection as well as the inspection of aircraft engine inlet cowls and checking the geometry of aircraft wing.
Challenges when inspecting turbine blades
-
Non-destructive inspection: Laser scanning, X-ray and micro-CT is used to image and qualify the internal structure of turbine blades. Turbine blades are rather expensive samples.
-
High inspection accuracy: both the freeform aerofoil surface of blades as well as specific features require accurate verification. In addition, internal walls thickness is subject to tight geometric deviations.
-
Dense material: inspection of dense material requires powerful x-ray source that allows x-rays to travel through the blade.
-
X-ray scattering: the inspection of dense materials potentially leads to x-ray scattering, which may cause inferior image quality.
-
Fast inspection: turbine blades are inspected at different stages in the prototyping and production process: after concluding molding and specific machining and finishing steps.
-
Fast CT reconstruction: in a production environment, it is important to quickly obtain inspection results.
-
Larger specimens: turbine blades are somewhat larger in size and require an inspection cabinet that offers sufficiently space.
Turbine Blade Inspection
Turbine blades are designed for optimum aerodynamics and mass center location, and constitute of advanced metal alloy castings and composites to increase strength, resist extreme temperature, and avoid corrosion.
