The aerofoil has 20 static pressure tappings along its chord on the upper and lower surfaces. They each connect to tubes that pass through the aerofoil and then out to clear, numbered, flexible tubes. Students can connect the tubes to other optional pressure-measurement instruments. They can then measure the pressure distribution around the aerofoil, from which they can find the lift.
Using a Pitot tube, students can traverse the aerofoil wake to find the downstream pressure distribution and find the drag on the aerofoil.
Students can compare these values of lift and drag with direct measurements found from a balance. They can also compare them with the results from another aerofoil with the same profile, such as the AF1600d. Varying the angle of attack of the aerofoil with respect to the air stream allows students to find the changes to the pressure distribution. It also allows investigations into the critical conditions at stall.
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.
