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.
Included with the wind tunnel:
- Three-Component Balance
- Balance Angle Feedback Unit
- Dual Differential Pressure Display Unit
- 32-Way Pressure Display Unit
- Dual Axis Pitot-Static Traverse
- Versatile Data Acquisition System (VDAS-F)
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)
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 450 mm by 450 mm and 1000 mm long. Package includes the Aerofoil with Tappings, a Three-Component Balance, two Differential Pressure Transducers, a 32-Way Pressure Display Unit and data acquisition (VDAS-F).
The high wing model aircraft with NACA profile wings for use with the Large Subsonic Wind Tunnel (AF1600) is good for experiments with lift, drag and pitching moment of fixed wing aircraft.
A set of different shape models for use with the Large Subsonic Wind Tunnel (AF1600S) each with identical frontal area to allow students to compare the different coefficient of drag for each shape. Includes a dummy stem for tests to cancel out the drag due to each model’s support arm.
A 150mm chord NACA2412 aerofoil with 590 span featuring a variable flap that adjusts +/- 90 degrees for use with the AF1600 Subsonic Wind Tunnel.
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.
