To design a more realistic low-boom supersonic demonstrator concept, theoretical engines were replaced with F-100 type engines. The original nacelle for the theoretical engine is replaced with a larger nacelle that is assumed adequate to house the F-100 engine. The process to redesign the configuration is then described and the rationales for design changes are given in some detail. Computational fluid dynamics (CFD) analysis was used to compute the equivalent area (A(sub e)) of the configuration during the redesign process. The goal of redesigning the configuration to match the CFD Ae of the configuration to a low-boom target was accomplished. The ground signature for CFD A(sub e) of the redesigned configuration has similar low-boom characteristics as that of the original low-boom configuration with theoretical engines.
