Aileron control of small-aspect-ratio aircraft; in particular, delta aircraft

Abstract

The aerodynamic and inertia characteristics associated with small-aspect-ratio wings are shown to affect aileron control, causing a tendency towards excessive aileron power combined with poor initial response. Simple formulae are given for the determination of the critical parameters and the effects of these on some aileron manoeuvres are analysed. Touchiness of lateral trimming is also expected to add to the handling difficulties of such aircraft. Finally, design criteria are discussed for the attainment of optimum aileron control.
