چکیده انگلیسی

The effect of wing sweep on the aerodynamic characteristics of Gurney flaps is examined. Wind tunnel models incorporating un-tapered 2.1 aspect ratio wings with sweeps of 0, 45 and 60 deg were designed and manufactured. Flap heights of 1% and 3% of the chord were evaluated. Testing was undertaken at Reynold's numbers of 100,000 and 150,000. The overarching result was that sweep attenuates the lift modulating ability of the flap, resulting from the effects of spanwise flow and reduced base suction behind the flap. Aerodynamic parameters were found to show a strong dependence on the cosine of the leading edge sweep angle as well as the square root of the flap height.
