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 کاملnumerical investigation of delta wings leading edge configuration effects on the flow behavior using large eddy simulation approach
determining characteristics and behavior of fluid flow and obtaining the aerodynamic coefficients are important and considerable tasks in investigation of flow over the bodies. in this research, leading edge radius effects on the flow behavior over a delta wing with a sweep angle of 50 degree at different reynolds numbers between 0.5×106 and 2.5×106 are investigated numerically. three different...
متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
