Suppression of wing rock of slender delta wings using a single neuron controller

Experimental 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...

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...

A New Simple Analytical Model for Flow Analysis Over Slender Delta Wings

Design of a Sliding Mode Control for Wing Rock Suppression in Highly-Swept Wing Aircraft

W ing rock is an oscillatory ro lling motion which arises at high angles of attack in aircraft with highly-swept wings. In the present paper, a method to suppress wing rock through sliding mode control is proposed. Sliding mode control is designed to min imize together roll angle error and command input through a cost function. The procedure is performed on a wing-only analytical model, the con...
