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 passes into the AF1600 through a honeycomb flow straightener and a grille. It then passes into an aerodynamically designed effuser (cone) that accelerates the air in a linear manner before it moves through the working section. Finally it passes through a diffuser, then into the 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.

The speed of the axial fan (and therefore the air velocity in the working section) is controlled by an electronic drive control in the separate On/Off unit mounted on the tunnel’s associated instrument frame along with other ancillaries.

The working section is of a square section with tapered chamfered corners and an acrylic roof and floor. The sides are full length acrylic panels, one side is hinged at the top and the other is removable. The whole unit is supported in an aluminium framework. Each side panel has a holder to support wind tunnel models. On the top of the working section are two Pitot devices and a wall tapping to measure the static pressure upstream and downstream of the working section.

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 horizontally (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.

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
  • 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
