The DELTALAB EA600 subsonic wind tunnel is a high level teaching aid designed for a wide range of experiments in aerodynamics. The integral fan generates a flow up to 45 m/s through a transparent test section of 230 x 230 mm. Different accessories are provided (including pitot tube and aerofoils) which allow verification of the laws of aerodynamics.

Teaching objectives

The wind tunnel allows a wide range of spectacular experiments, including:
- Measurement of flow velocity and gradients in the test section
- Measurement of pressure differentials around an aerofoil
- Study of the pressure gradient around a cylinder

Using additional equipment:
- Measurement of lift and drag using a 2- component balance
- Measurement of lift, drag and pitching moment with a 3-component balance


Technical specifications

The wind tunnel is bench-mounted to allow easy mounting of the instruments and models.
It consists of:
· A carefully designed contraction to provide uniform air flow
· A transparent test section with panels prepared for the location of probes
· A diffuser and honey comb connecting the test section to the suction fan
· An axial fan and motor assembly mounted on a separate metal support, to provide isolation from vibration in the test section. The variable speed fan is controlled to provide air speed variation from 1 – 45 m/s
- A diffuser for return of air to the laboratory
- The wind-tunnel is of metal with a stoved finish and PVC construction
- Test section: 230 x 230 x 500 mm
- Maximum airflow: 45 m/s
- Fan power: 3 kW
