The Turbomachinery and Propulsion Department (TU) built its long-lasting experimental tradition on-field, conceiving, developing and operating measurement techniques and devices that could stand the challenging conditions of typical turbomachinery flows.

The portfolio of the TU Department provides a wide range of measurement techniques of interest for the turbomachinery community, from pressure and temperature measurements to heat-transfer and turbulence characterization, with particular attention devoted to the miniaturization of the devices and their applicability to real engine testing.

Within the VKI-Instrumentation Service, the TU Department provides its expertise in the following fields:

Pressure measurements

  • Pneumatic miniaturized total pressure probes
  • Pneumatic miniaturized multi-hole probes (3hole, 4hole and 5hole probes)
  • Cooled pneumatic multi-hole pressure probes
  • Fast-response total pressure and directional probes (virtual 3hole, 3hole)
  • Cooled fast-response pressure probe (up to 1700 [K])
