A set of two NACA0012 aerofoils.
One aerofoil has a span that extends the full width of the working section of the Subsonic Wind Tunnel (AF1600S). This model has the characteristics of a two-dimensional aerofoil.
The other aerofoil has a span that extends for half of the working section of the wind tunnel. This model has the characteristics of a three-dimensional aerofoil. Comparing the measured lift and drag of the two aerofoils shows the differences between two-dimensional and three-dimensional aerofoils.
Using a Pitot tube, students can traverse the aerofoil wake of the full-width aerofoil. This gives them the downstream pressure distribution to find the drag on the aerofoil. They can compare their results to direct measurements from a balance (available separately).
Students can compare the results from the full-width aerofoil with the tapped aerofoil model (AF1600b, available separately) as it has the same (NACA0012) section.
TecQuipment’s Smoke Generator (AFA11, not included) increases the educational value of the experiments by showing the flow of air around the model.
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).
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.
A pair of boundary layer models with a mounting plate, also a pitot and a static probe for investigating boundary layer. One plate is roughened, the other smooth to allow comparisons on boundary layer growth.
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.
