Wind tunnel: 3.5m by 2.4m by 10.5m

Working section

The dimensions of the working section are 3.5m wide, by 2.4m high, by 10.5m long. It also offers:

• wind speed range from 4 to 40 metres per second with less than 0.2% turbulence
• air chiller to control airflow temperature to 19 °C

Balances

The tunnel has a 6 component overhead balance and a strut-mounted 'in-car' balance.

The Nutem 6-component overhead balance can be set at any yaw angle. It includes:

• a concentric turntable independent of the balance
• strut attachments with adjustable pitch angle

Alternative virtual roll centres at:

• tunnel centre-line
• 300mm above moving ground
• flex-link design with independent load cells for each measurement component

Adjustable maximum load ranges are:

• lift 300-11000 N
• fx 258-5000 N
• fy 645-3350 N
• yaw moment 83 - 830 Nm
• pitch moment 83 - 3500 Nm
• roll moment 165 - 2500 Nm
• analogue/digital conversion for acquisition of signals

Aerotech 6 component internal balance features include:

• in model mount from a vertical strut
• a faired strut with ride height control mounted from Nutem ground frame
• a strain gauged cage design

Maximum load ranges are:

• downforce 3600 N
• drag 900 N
• side Force 1000 N
• yaw moment 260 Nm
• pitch moment 700 Nm
• roll moment 120 Nm

Other equipment includes:

• a ZOC pressure scanning system
• 2D particle image velocimetry

Moving ground

The dimensions of the moving ground are 1.95m wide by 4m long belt, with a speed range up to 40 metres per second. It has a:

• boundary layer control which gives >99.8% of free stream velocity 2mm above belt

Model scales

The wind tunnel is suitable for up to 50% race car models.

Other equipment

Our tunnel also features:

• a control and acquisition system
• motor drive systems for propeller testing
