NACA 0012 Aerofoil Model with Tappings
Model Number: AF1450B
Measure aerofoil pressure distribution, lift, drag, and stall behavior in the AF1450 Subsonic Wind Tunnel.
Overview
A 150 mm chord 300 mm span NACA0012 aerofoil with pressure tappings for use with the AF1450 Subsonic Wind Tunnel.
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. 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.
