Abstract
Concurrent engineering approaches for the disciplines of computational fluid dynamics (CFD) and electromagnetics (CEM) are necessary for designing future high-performance aircraft. A characteristic-based finite-volume time-domain (FVTD) computational algorithm, used by CFD and now applied toCEM, is implemented to analyze the radar cross section (RCS) of the ogive and cone-sphere. The technique utilizes a scattered-field formulation of the time-dependent Maxwell equations. The FVTD formulation implements a monotone upstream-centered scheme for conservation laws for the flux evaluation and a Runge-Kutta multi-stage scheme for the time integration. The results are obtained from the electromagnetic fields via a Fourier transform and a near-to-far field transformation.
