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 AF1450d symmetrical aerofoils. The Three-Component Balance (AF1450t, 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.
TecQuipment Smoke Generator (AFA11, not included) increases the educational value of the experiments by showing the flow of air around the model.
