3D printing improves testing for gas turbine components

Gas turbines are complex components to manufacture, but additive manufacturing has been successfully utilized to accelerate design cycle times, reduce development test times, provide better test data and reduce the overall time to the release of the final component. It also allows for testing to be performed earlier, as early as the concept or preliminary design phases. This means that there is less likelihood that the entire component will have to be redesigned, as problem areas can be detected and eliminated early.

In a recent case study, a Siemens Energy SGT-A05 industrial gas turbine engine line was manufactured, and additive manufacturing was used for aerodynamic development testing within the preliminary design phase for boundary condition definition of new compressor static flow path components.
