The leading-edge vortex of swift wing-shaped delta wings
Recent investigations on the aerodynamics of natural fliers have illuminated the significance of the leading-edge vortex (LEV) for lift generation in a variety of flight conditions. A well-documented example of an LEV is that generated by aircraft with highly swept, delta-shaped wings. While the wing aerodynamics of a manoeuvring aircraft, a bird gliding and a bird in flapping flight vary signi...

متن کاملMotion Effects on Leading-Edge Vortex Behavior Over Delta Wings and Generalized Modeling
Effects of static attitude and three different motions on vortex behavior and its breakdown over delta wings have been investigated. These motions include 1) harmonic oscillation or ramp-and-hold motion in roll at constant resultant angle of attack, 2) harmonic oscillation or ramp-and-hold in pitch and 3) coning at constant resultant angle of attack A basic 65° delta wing configuration was test...
متن کاملOn the phenomenon of vortex street breakdown
A von Karman vortex street generated in the usual way was subjected to a deceleration, thereby changing the ratio of longitudinal to lateral spacing between the vortices. Distortion of the individual vortices followed which resulted in annihilation of concentrated vortex regions and creation of a stationary wake flow. This wake flow was itself dynamically unstable and developed into a new vorte...
متن کاملDual leading-edge vortices on flapping wings.
An experimental investigation was performed with two aims: (1) to clarify the existence of the dual leading-edge vortices (i.e. two vortices with the same sense of rotation located close to the leading edge above the leeward wing surface) observed on flapping wings in previous studies; (2) to study systematically the influences of kinematic and geometric parameters on such a vortical structure....
