Abstract

Force tests were carried out on a typical missile configuration, featuring a slender body cruciform canard and cruciform tail, in a 1.2-m wind tunnel at subsonic, transonic, and supersonic speeds at various incidence and control deflections. Some discussions on the induced rolling moment experienced by this configuration during maneuvering attitudes are presented. It was observed that the induced rolling moment was primarily due to the interaction of asymmetric flow field induced by the canard deflections on the tail. This induced rolling moment was negligibly small when the tail fins were removed. Also, the variation of the induced rolling moment with incidence was approximately sinusoidal for most of the canard deflections. This paper also includes some discussions on a current method adopted for eliminating such undesirable induced rolling moments by allowing the tail fin to roll freely.
