Blade tip-timing is an extensively used technique for measuring blade vibrations in turbine and compressor stages; it is one of the preferred techniques used for characterizing their dynamic behaviors using non-contact probes. Typically, arrival time signals are acquired and processed by a dedicated measurement system. Performing a sensitivity analysis on the data processing parameters is essential for the proper design of tip-timing test campaigns.

Article Synopsis
  • Non-destructive testing is increasingly vital for gas turbine manufacturers' structural health monitoring.
  • The tip-timing method is favored for analyzing the dynamic behavior of turbine blades using non-contact technology.
  • This study examines the uncertainty in measuring Blade Tip-Timing, focusing on both the measurement setup and data processing, and assesses the impact of electronic elements and signal processing under various conditions.

The fused filament fabrication (FFF) process is widely used for producing prototypes and functional parts for diverse applications. While FFF is particularly attractive due to its cost-effectiveness, on the other hand, the fabricated parts have limitations in terms of large manufacturing time and reduced mechanical properties. The latter is strongly influenced by the fabrication process parameters, which affect the interlayer bonding and the adhesion between consecutive layers.
