Close-Coupled Oscillating Canard Effects on Post-Stall Lift Enhancement

摘要

The effects of an oscillating close-coupled canard on the canard/wing vortexinteraction for increased lift enhancement were studied. Two test conditions were studied: the first with a model angle of attack of 22 deg. and the second of 34 deg. The canard was positioned at three mean deflection angles equal to 4, 7 and 10 deg. for the model angle of attack of 22 deg. and -4, -7 and -10 deg. for the model angle of attack of 34 deg. At each of the canard mean deflection angles,
