Applications & Measurement Solutions

 

Turbine engines are higly specialized aircraft components that must meet enormous safety requirements. One way to meet these new metrological requirements is the use of high-resolution, optical 3D metrology.

The following highly critical turbine engine parts can be measured optically:

 

>> Break edges

of fan blades, compressor discs, turbine blades, blisks, cases etc. according to ASME

 

>> Leading and trailing edge of turbine blades

even at sharp opening angles due to a special illumination technology that enables the measurement of steep flanks

 

>> Small defects

of components (i.e. rotor blades) or component assemblies (i.e. motors) by measuring width, length, depth and volume of fractures, scratches etc.

 

>> Cooling holes

by automatically verifying angle, size, and shape of up to 500 cooling holes, some of them with different shapes

 

>> Roughness measurements

to i.e. verify coating processes or MRO actions. Roughness is measured profile based (Ra, Rq, Rz) and area based (Sa, Sq, Sz)

Measurement Report

Turbine blade measurement using optical Focus-Variation technique

 

The measuring object is a turbine blade, measured with the µCMM and a rotation unit (Real3D). In order to analyze the turbine blade, the following parameters are measured:

 

  • Geometry of a cooling hole
  • Defects
  • Airfoil analysis (leading & trailing edge radii, form deviation, profile twist, etc.)
  • Fir tree geometry
  • Profile & areal roughness

Non-contact and highly accurate measurement of critical turbine engine components

 

Turbine engines are highly specialized aircraft components that must meet enormous safety criteria. They are precision components with complex geometries and tolerances in the sometimes single-digit μm range. Functional component features such as micro bores for cooling turbine blades or defined broken edges on highly stressed components contribute both to increased efficiency and to the safe operation of these high-performance systems. One way to meet the new metrological requirements is the use of high-resolution, optical 3D metrology. Learn more about applications of Focus-Variation for break edge, defect and geometry measurement, measurement of cooling holes, coating processes, cutting edge measurement, possibilities of artificial intelligence and much more.
