This paper describes the development of a new boundary-element method for predicting the unsteady compressible flow past general configurations in subsonic flow. It permits the actual geometry of the configuration to be represented and computes the cou- pling between the steady and unsteady flow components. It adopts a description of the unsteady deformation of the geometry that avoids many of the limitations inherent with vortex- and doublet-lattice methods. The paper describes the issues that have been ad- dressed in developing the method and, through 2D and 3D validation cases, demonstrates advantages over some established methods.
