Subsonic Suction Wind Tunnel Description and Specifications for Lab Tenders
Subsonic Suction Wind Tunnel.
Subsonic Suction Wind Tunnel
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
