LP3 rig: ducted low-speed axial fan

The LP3 test bench consists of a low speed aircraft HVAC fan (Technofan technology) with a heterogeneous stator (3 vanes thickened due to structural purposes), a turbulence control screen (TCS), an anechoic setting chamber to avoid end reflections and 2 microphone arrays (upstream and downstream of the fan, 114 microphones).
