NACA 0012 AEROFOIL MODEL WITH TAPPINGS

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 AF1300D. 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.

TecQuipment’s Smoke Generator (AF1300Y, not included) increases the educational value of the experiments by showing the flow of air around the model.

Case Study
Texas A&M University Zachry Engineering Education Complex

Recently one of the USA’s largest engineering schools, Texas A&M University, invested in a new engineering education complex that would revolutionise the way they teach their 20,000 engineering students. One element of this new complex was a new model for laboratories that would allow them to fully utilise equipment and space by creating “common labs”, shared facilities within Zachry Engineering Education Complex completed in 2018. The new building was only part of the story; they invested heavily in new teaching equipment to be housed in this facility, including a vast range of practical engineering teaching products from TecQuipment.
