Engineering: Aerodynamics Learning Equipment

A wind tunnel is a tool used in aerodynamic research to study the effects of air moving past solid objects. A wind tunnel may consist of a tubular passage with the object under test mounted in the middle. Air is made to move past the object by a powerful fan system or other means. These products help teach students aerodynamic and air flow hands-on.

Subsonic Wind Tunnel 600mm (AF1600 - Base Unit)

An open circuit suction subsonic wind tunnel with a working section of 600 mm by 600 mm and 1250 mm long. All instrumentation required to begin experimentation is included.

Subsonic Wind Tunnel

A practical open-circuit suction wind tunnel for experiments in aerodynamics. The Subsonic Wind Tunnel is a cost effective option to provide extensive experimental capabilities in aerodynamics.

The wind tunnel gives accurate results and is suitable for undergraduate study and research projects. TecQuipment offers a comprehensive range of instrumentation, including a computer-based data acquisition system.

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 atmosphere.

A separate control and instrumentation unit controls the speed of the air velocity in the working section and supplies electrical power to other instruments.

The working area 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 wind tunnel models. Supplied with the wind tunnel are a protractor and a model holder to support and accurately adjust the angle of any model fitted.

Two Pitot-static tubes are provided with the wind tunnel. One is fixed near to the inlet of the working section and measures the air-flow rate. The second Pitot-static tube is attached to a two-axis traverse that allows movement horizonally (fore to aft) and vertically, for measurements throughout the working area. The traverse positions are measured using integrated DTI devices. They connect to digital pressure displays so users can observe detailed pressure readings.

A metal frame supports the wind tunnel. The frame includes lockable castors for convenient mobility. Electronic sensors on the included instrumentation can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®, included). VDAS® allows accurate real-time data capture, monitoring, display, calculation and charting of all relevant parameters on a suitable computer.

Subsonic Wind Tunnel: Learning Outcomes

A wide variety of subsonic aerodynamics experiments are possible (models not included), for example:

  • 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
  • Pressure distribution around objects under sub- and super-critical flow conditions
  • Study of characteristics of models involving basic measurement of lift and drag forces
  • Study of the characteristics of aerofoils involving measurements of lift, drag and pitching moment
  • Drag force on a bluff body normal to an air flow
  • Flow visualisation (with Smoke Generator)

Subsonic Wind Tunnel Starter Set

A starter set consisting of the Subsonic Wind Tunnel AF1300, Basic Lift and Drag Balance AF1300Z and a set of Three Dimensional Drag Models AF1300J.

Subsonic Wind Tunnel

The Set A set of parts including TecQuipment’s Subsonic Wind Tunnel (AF1300), the Basic Lift and Drag Balance (AF1300Z) and the Three-dimensional Drag Models (AF1300J). This complete starter set includes all parts needed for experiments in aerodynamic drag.

The Wind Tunnel (AF1300) The wind tunnel gives accurate results and is suitable for undergraduate study and research projects. TecQuipment offers a range of additional and optional models and instrumentation to extend the experiments, including a data acquisition system (VDAS®).

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). The control and instrumentation unit also includes manometers and electrical outlets to supply electrical power to other optional instruments.

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 of the instrumentation unit (or other optional instruments) to show pressure.

A metal frame supports the wind tunnel. The frame includes lockable castors for convenient mobility. Optional wind tunnel instruments can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®, not included). VDAS® allows accurate real-time data capture, monitoring, display, calculation and charting of all relevant parameters on a suitable computer.

The Basic Lift and Drag Balance (AF1300Z) A simple-to-fit balance that mounts on the side of the wind tunnel working section. This balance holds the models in the working section and measures the lift and drag forces on the models, created by the air moving past them. The balance also works with other optional models.

The balance includes a digital display unit to show the forces. The display can connect to TecQuipment’s VDAS® to log experiment data on a suitable computer.

The Three-dimensional Drag Models (AF1300J) A set of models, each with a different shape but the same frontal area for direct comparisons. The models fit in the wind tunnel working section, held by the balance to allow students to see how shape affects aerodynamic drag. The models include ‘classic’ aerodynamic test shapes including a smooth sphere, a dimpled sphere and a streamline shape.

Experiments This Starter Set includes parts for experiments in three dimensional drag due to different body shapes and surface dimples.
