Abstract

This paper is concerned with designing a composite wing structure with enhanced roll maneuver capability at high dynamic pressures using a control system to retwist and recamber the wing. The approach selected in this paper is a two step process. In the first step, minimum weight design satisfying requirements on strength, aileron efficiency and flutter for a specified set of fiber oritations was obtained. The control system was then designed to retwist and recamber the wing to counteract the detrimental twisting moment produced by the aileron. The distribution of control forces was obtained from a technique referred to as `Fictious Control Surfaces'. The technique of retwisting and recambering of a flexible wing demonstrated a full recovery of roll rate at all dynamic pressures.
