The Bench-Top Wind Tunnel offers a complete system ready foraerodynamic experimentation. A range of models and all necessary instrumentationare included to provide accurate results, suitable for undergraduate study andresearch projects. Pitot tubes attach to the working section and connect to aliquid manometer so students can analyse pressure at different positions andcalculate air speed. supplies a two-component balance with the Wind Tunnel. Ituses an electronic force sensor to measure the lift or drag forces on modelsfitted to the Working Section. It has a clear digital display giving a directreading of the measured force value, for real-time data collection. Abench-mounting metal frame holds all parts of the wind tunnel in one compactunit. Air enters the tunnel through an aerodynamically designed effuser andhoneycomb flow straightener that accelerates the air linearly. It then entersthe working section and passes through a grille before moving through a diffuserand then to a variable-speed fan. The grille protects the fan from damage byloose objects. The air leaves the fan, passes up through a silencer unit andthen back out to atmosphere. A controller with an electronic drive allows theuser to vary the fan speed accurately from zero to full speed. The electronicdrive keeps the chosen speed constant.
