| Abstract: | Linearized theory for compressible unsteady flow is used to treat the problem of a partial-span rectangular control surface, hinged at its leading edge and mounted on a rectangular wing, oscillating in supersonic flow. The motions of the wing-aileron configuration are assumed to consist of vertical translation, pitching, and aileron rotation. The velocity potentials for this configuration are derived as power series in terms of a frequency parameter to the fifth power of the frequency of oscillation. From these potentials closed expressions for section force and moment coefficients at any spanwise location we derived. The section force and moment coefficients are employed in a particular flutter study in which the spanwise position of the aileron is varied. |
