Lifetime Prediction for Gas & Steam Turbines

Checking turbine lifetimes is vital to ensure that components do not fail prematurely. One aspect is the wear on turbine blades, which can be analyzed at different stages during operation. This makes precise forecasts of component lifespan possible. In manufacturing environments, contactless measurement systems from GOM are used to control the uniform application of thermal barrier coating onto blades.

  • Analysis of Thermal Barrier Coating (TBC)
  • Control of Cooling Holes and Pitch Corrosion
  • Inspection of Blade Deformation caused by Airflow Creep

CFD & FEA Analysis on Gas & Steam Turbines

Real component geometries are the most suitable for efficiency level analysis and efficiency optimization. Computational Fluid Dynamics analysis (CFD) makes it possible to analyze factors such as turbulence, flow and resistance.

To improve turbine efficiency, systems from GOM measure blade geometry, leading and trailing edges as well as the opening angles between individual blades. Intelligent software solutions help define the current efficiency ratings based on wear.

The finite element method greatly improves geometry and construction in component design. Precise 3D coordinate measuring data for real components supplies a reliable basis for comprehensive simulations of component behavior and their capacity limits.

Reverse Engineering / Golden Master

CAD data is remastered several times during the design process. All too often, suitable CAD data for an OEM or supplier component is not available. In this case, 3D digitizing using systems from GOM and reverse engineering offer intelligent solutions for reliable documentation. When it comes to making changes to individual components or tools, the CAD data can be swiftly updated and used as a reference for incoming parts inspection. The precise 3D point clouds of ATOS help gas and steam turbine operators create golden masters from third-party or self-manufactured turbine blades based on a comparison of different 3D models.
