Transonic Wind Tunnel PT-1

RI-019
Wind Tunnel
Infrastructure
CIRA
Description

CIRA Transonic Wind Tunnel PT-1 is the only Italian aerodynamic transonic wind tunnel. It is a pressurized facility, able to contribute to both industrial and research programs with an aerodynamic testing capability over the subsonic, transonic and supersonic regimes.

Due to its size, it is used mainly for research activities and for industrial purposes when aircraft parts have to be aerodynamically characterized in order to support the preliminary airplane design phases.

A list of the typical test articles is reported in the following:

  •         2D models, e.g. representative of airfoils, rotor and turbine blades sections
  •         Half-wings and half-models
  •         3D models, e.g. representative of complete vehicles configurations or of slender bodies as missiles and launchers
  •         Full scale probes
  •         Specific test set-up, e.g. dedicated to aerodynamic and aeroacoustic characterization of panels or aerodynamic protrusions, to characterization and validation of flow control devices, to the determination of laminar boundary layer sensitivity to geometry imperfections due to working tolerances.

CIRA PT-1 personnel fully support customers for wind tunnel test activity, engineering, data analysis and model definition.
