Unsteady Flows Produced by Small Amplitude Oscillations of the Canard of an X-29 Model

Abstract

This investigation develops previous flow visualization studies by quantifying the flowfield around the tandem wing of an X-29 model in the wake of an oscillating canard. The local velocity above and below the wing was measured with the canard oscillating and compared to the cases with the canard static. A structured disturbance pattern was documented in the wake of the oscillating canard then compared to the random flow pattern behind the static canard. Considering the dual vortex system shed from the oscillating canard, the tip vortex dominates the flowfield, the leading edge vortex passes well above the wing. (EDC)
