A compact, practical open-circuit suction wind tunnel for studying aerodynamics. The wind tunnel saves time and money compared with full-scale wind tunnels or airborne laboratories.
The wind tunnel provides accurate results and is suitable for undergraduate study and research projects.
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 grill before moving through a diffuser and then to a variable-speed axial fan. The grill protects the fan from damage by loose objects. The air leaves the fan, passes through a silencer unit and then back out to atmosphere.
A separate control and instrumentation unit controls the speed of the axial fan (and the air velocity in the working section).
A metal frame supports the wind tunnel. The frame includes lockable castors for convenient mobility.
Included with the wind tunnel:
- Three-Component Balance (AF1450T)
- Balance Angle Feedback Unit (AFA4)
- NACA 0012 Aerofoil with Tappings (AF1450B)
- Dual Differential Pressure Display (DP6)
- 32-Way Pressure Display Unit (AFA6)
- Pitot Static Traverse x 2 (AF1450X)
- Model Holder
- Versatile Data Acquisition System (VDAS-F) - frame mounted
A wide variety of subsonic aerodynamics experiments (some need ancillaries), including:
- Flow past bluff and streamlined bodies with pressure and velocity observations in the wake
- Investigations into boundary layer development
- Inﬂuence of aspect ratio on aerofoil performance
- Performance of an aerofoil with ﬂap, inﬂ uence of ﬂap angle on lift, drag and stall
- Pressure distribution around a cylinder under sub- and super-critical ﬂ ow conditions
- Study of characteristics of models involving basic measurement of lift and drag forces
- Study of the characteristics of three-dimensional aerofoils involving measurements of lift, drag and pitching moment
- Study of the pressure distribution around an aerofoil model to derive the lift, and comparison with direct measurements of lift
- Drag force on a bluff body normal to an air ﬂow
- Flow visualisation
The electronic and aeronautical test facility at Milton Keynes College, UK recently purchased an AF1300 Subsonic Wind Tunnel for the teaching of the Level 3 Aeronautical Engineering BTEC Diploma students, which is used on a regular basis as part of the course.
An open circuit suction subsonic wind tunnel with a working section of 600 mm by 600 mm and 1250 mm long. Package includes a Three-Component Balance, Dual Axis Pressure Traverse and associated instrumentation such as a 32-Way Pressure Display Unit and Versatile Data Acquisition System (VDAS-F).
A flat boundary layer model to illustrate the phenomena of boundary layer development and separation. For use with the AF1450 Subsonic Wind Tunnel.
Five drag investigation models for use with the TecQuipment AF1450 wind tunnel - a streamlined shape, a sphere, hemisphere, "dimpled" sphere, and a flat plate. All the models have a 50mm frontal area for easy comparison.
This smoke generator and probe are an optional ancillary to TecQuipment's AF1125, AF1450 and AF1600. It allows the observation of airflow in subsonic wind tunnels and other airflow situations.
