DESCRIPTION

The C30 – Computer Controlled Wind Tunnel enables the user to carry out advanced studies in the Aerodynamics fields including boundary layer experiments, flow visualisation, pressure distribution, study of turbulence and offering the possibility of developing self-design aerodynamics profiles to be tested.

The wind tunnel comprises outstanding features such as computer control, remote operation, datalogging and diagrams plotting in real time.

The system also benefits from clear visualisation of every model under test due to the architecture of the working section in transparent material and the compact design of all components.

TECHNICAL SPECIFICATIONS

• • A stand-alone computer controlled subsonic wind tunnel for conducting experiments in aerodynamics
  • The wind tunnel is mounted on a steel base on wheels for mobility
  • Working section of 310mm by 310mm and 600mm long
  • The unit operates as an open circuit system
  • Inverter controlled AC suction fan to drag the air flow through the working section
  • Accurate speed control up to 40m/s
  • The duct incorporates a honeycomb flow straightener to even the direction of flow
