Analytical Investigation of Hinge Moments on Missile Trailing-Edge Control Surfaces.
Abstract
An inviscid analysis of a fin-alone with a trailing-edge elevon was made assuming various perturbations of the configuration in order to gain some insight into high elevon hinge moments experienced in flight on a missile. The perturbations examined were camber, twist and dihedral, all of which could be induced by thermal distortion. A possible fix was also investigated by considering a gap to occur between the fin trailing edge and the elevon leading edge. Deductions on the cause of the high hinge moments were made based on the calculations. The Mach number range considered was 1.6 to 3.0.
