Subsonic Wind Tunnel

Subsonic Wind Tunnel

Specification :

Self-contained wind tunnel for the study of subsonic aerodynamics, complete with two- component balance system and air speed indicator
• Special features:
- Contraction and Diffuser: precision glass fibre mouldings
- Test Section: clear acrylic, which retracts to permit access to the models.
- Adjustment of models can be made with the tunnel in operation.
- Fan: Variable speed motor driven unit downstream of the working section permitting stepless control of airspeed between 0 and 26ms-1
- Balance: Lift and drag Lift
- 7.0N, Drag
- 2.5N, Sensitivity ±0.01N
- Air speed: Indicated on inclined manometer directly calibrated in m/s
- Support structure: A strong steel frame including working surface and fitted with castors for easy movement
• Suitable for undergraduate and simple research work.
• Working section: 304mm wide x 304mm high x 457mm long (octagonal cross- section)
• Contraction area ratio: 3:1
• Motor rating: 1.5kW
• A user instruction manual is supplied
• Optional models and instrumentation allow:
- Investigation of the development of the boundary layer on a flat plate by measurement of total head distribution
- Flow visualisation studies around an aerofoil
- Measurement of pressure distribution around an aerofoil at various angles of attack or around a cylinder
- Measurement of lift and drag on an aerofoil with leading edge slot and trailing edge flap
- Velocity and pressure distribution measurements using a pitot static tube and yaw probe
- Measurement of drag for models of different shapes but common equatorial diameter
- Demonstration of flutter of an aerofoil
- Calibration of the wind tunnel velocity indicator using a pitot static tube
- Investigation of the wake behind a cylinder or aerofoil using a wake survey rake
