A compact, free-standing, open-circuit suction subsonic wind tunnel with a working section of 305 mm by 305 mm and 600 mm long, allowing students to perform advanced study such as analysing boundary layers, performing flow visualisation and observing velocity in the wake, offering extensive teaching and research functionality
Key Features
• A wind tunnel for conducting experiments in aerodynamics
• Safe, compact, open-circuit suction wind tunnel – a cost effective solution when compared to full-sale wind tunnels
• The optional ancillaries work with TecQuipment’s Versatile Data Acquisition System (VDAS®)
• Additional models and instruments available to extend the range of experiments
• Wind tunnel controls mount on a separate, free-standing instrument frame for ease of use
• The wind tunnel has wheels for easy mobility
• Also available as a starter set with a basic lift and drag balance and a set of models
Description
Air enters the tunnel through an aerodynamically designed effuser (cone) that accelerates the air linearly. It then enters the working section and passes through a grille before moving through a diffuser and then to a variable-speed axial fan. The grille protects the fan from damage by loose objects. The air leaves the fan, passes through a silencer unit and then back out to the atmosphere.
A separate control and instrumentation unit controls the speed of the axial fan (and the air velocity in the working section). The control and instrumentation unit also includes manometers and electrical outlets to supply electrical power to other optional instruments.
A metal frame supports the wind tunnel. The frame includes lockable castors for convenient mobility.
Working Section
The working section of the tunnel is a square section with a clear roof, sides and floor. The sides are removable. The floor and each side panel has a special position to support the optional wind tunnel models. Supplied with the wind tunnel are a protractor and a model holder to support and accurately adjust the angle of any models fitted.
Two traversing probes fit on the working section. One is a Pitot-static tube and the other a standard Pitot tube. They fit upstream and downstream of any models and connect to the manometers on the instrumentation unit (or other optional instruments) to show pressure.
Included with the AF1300
Model Holder
The model holder is supplied to hold a model if a balance is not used. It is designed to hold a shaft of diameter 11.95 ±0.015 mm (diameter) and 215 ±1.25 mm (length) mounting stem.
Protractor
The protractor fits on to the shaft of a model when a Balance is not being used. It can be used when setting up models and rotating them during experiments.
