چکیده
This paper deals with the study of flow around a pitching wing at high angle attack. Different amplitudes and frequencies are studied using DIC LPT measurements. The Fluid Structure Interactions shown exhibit that vortex shedding could be reduced by actuating specific frequencies.

Effect of Amplitude and Mean Angle of Attack on the Unsteady Surface Pressure of a Pitching Airfoil
Details of pressure distributions, on a two dimensional airfoil oscillating in pitch through stall, in a 0.8 0.8 m low-speed wind tunnel are presented. Pitching occurred about the airfoils quarter-chord axis. Pitch rate, Reynolds number, and oscillation amplitudes were varied to determine the effects on pressure and lift distributions. It was found that mean angle of attack and pitching amplitu...
متن کاملEffect of Wing Sweep Angle on the Vortex Interaction of a Tail-Wing Configuration
The goal of this investigation is to study the effect of wing sweep angle on the horizontal wing-body- tail configurations in subsonic flow. For this purpose, a series of wind tunnel tests were conducted on a model having a moveable horizontal tail and a wing planform with different sweep angles. Tests were performed at different tail deflection angles. Static surface pressure distribution over...
متن کاملModeling and Simulation of the Fluid-Structure Interactions in Passively-Pitching Flapping Wings of Flying Microrobots
We present a study of the dynamics of passive wing-pitching in flapping-wing hovering flight, employing an integrated simulation approach. Here, the motion of a perfectly rigid wing is described using the Euler-Lagrange equation in Kane’s formulation, in which the passive rotating mechanism (flexure hinge) is modeled as a single-axis elastic beam and the total aerodynamic moment is computed by ...
متن کاملHigh Angle of Attack Aerodynamics
High angle of attack aerodynamics is inherently associated with: • separated flows, and thus nonlinear aerodynamics > one of the key aspects is the interaction of components, and in particular, vortex flows (vortex bursting is also an important effect) • heavily dependent on wind tunnel testing • connected with flight simulation to ensure good handling qualities > this means that large amounts ...
متن کاملThe motion of a plate in a rotating fluid at an arbitrary angle of attack
Slow motion of a thin plate at a finite angle of attack in a rotating container filled with a viscous incompressible fluid is analysed. The Ross by and Ekman numbers are assumed to be small. The solution method is developed by studying horizontal translation of an elliptical plate. The plate is shown to carry a stagnant Taylor column with it as it moves. Detailed analysis of the structure of th...
