150MM CHORD NACA 2412 AEROFOIL WITH VARIABLE FLAP An unsymmetrical section (cambered) aerofoil with adjustable flap. The adjustable flap allows students to study the effects of control surfaces such as flaps, ailerons, elevator or rudder. Students can also examine the difference between unsymmetrical and symmetrical aerofoils, by comparing the results to the AF1300d symmetrical aerofoils. The Three-Component Balance (AF1300t, available separately) can hold the aerofoil to measure lift, drag and pitching moment. Using a Pitot tube, students can traverse the aerofoil wake to find the downstream pressure distribution and find the drag on the aerofoil. They can compare these results with the direct measurements from a balance. Smoke Generator (AFA11, not included) increases the educational value of the experiments by showing the flow of air around the model.
