Some Simple Conical Camber Shapes to produce Low Lift-Dependent Drag on a Slender Delta Wing

ROYAL AIRCRAFT ESTABLISHMENT Some simple conical c~mbcr shapes to produce low lift-depend,cnt drag on a slender delta wing G. G. Brebner This note presents some of the theoretical aerodynamic characteristics of narrow delta wings having flat csntre portions and two types of simple conical camber designed to produce zero load at the leading edge at the design C,.,. Slender wing theory is used in...

Stability of Symmetric and Asymmetric Vortices over Slender Conical Wing-Body Combinations

Theoretical analyses of the stability of symmetric and asymmetric vortex pairs over slender conical wing-body combinations consisting of a slender circular or elliptic cone and a flat-plate delta wing under small perturbations in an inviscid incompressible steady flow at high angles of attack with or without sideslip are presented. The three-dimensional flow problem is reduced to a problem in t...

Non-conical Flow past Slender Wings with Leading-edge

Calculations of the Effect of Blowing from the Leading Edges of a Slender Delta Wing

The thin-jet model, applied by Spence to the study of the jet flap, is combined with the vortex-sheet model, applied by Mangler and Smith to the study of leading-edge separation, to study the effect of blowing from the leading edges of a delta wing at incidence. A jet-vortex sheet, supporting a pressure difference related to the curvature of the streamlines in it, leaves the leading edge in a d...

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

Wing rock is a highly nonlinear phenomenon in which the aircraft undergoes limit cycle roll oscillations at high angles of attack. A single neuron control scheme for suppression of wing rock of slender delta wings is presented. The effectiveness of the control scheme is demonstrated through software simulation and real-time control experiments in a wind tunnel on a 80 swept back wing. The suppr...
