The achievement of natural LFC in SST configurations featuring externally braced, very highly swept, high structural aspect ratio wing planforms results in outstandingly high cruise L/D ratios while maintaining low sonic-boom overpressures. A conceptual design study has been conducted with a view to range capability maximization in SSTs. A three-body configuration employing a highly swept, strut-braced planform, in which a central fuselage and two smaller outboard bodies alleviate structural wing bending and torsion, is noted to allow further increases in wingspan and aspect ratio which commensurately reduce lift-induced wave-plus-vortex drag and volume-induced wave drag.
