Improvement in wing performance using a wing with sinusoidal leading edge (The effect of the wing camber and the wing camber position)

Effect 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...

Robust MRAC for a Wing Rock Phenomenon in Delta Wing Aircrafts

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

Aiaa 2002–0413 Active Flow Control of Separation on a Wing with Oscillatory Camber

Aiaa 2001–0293 Active Control of Separation on a Wing with Conformal Camber

A preliminary investigation of a wing with a conformal camber is discussed. The wing uses an adaptive actuator mounted internally to alter the shape of the suction surface which results in a change in the effective camber by increasing the maximum thickness and moving the location of maximum thickness aft. Since the actuator motion can be altered continuously, this allows the wing shape to be e...

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...
