A dimensionally size-efficient aircraft being of a twin-
fuselage configuration that addresses long-range high-capacity passenger commercial or military application needs, unique in that propelling engines (two, three, or four engine arrangements) are centrally mounted aft of a central cross-
wing section, that section addressing the structural requirements of
fuselage attachment with a means of passage between fuselages, the outer main wings being free from hanging appendages, thereby enabling efficient aerodynamic-lift wing design, the configuration using a split stabilizer and a split vertical
tail for stable aerodynamic control. Engine locations are biased high and aft with the central and outer wings providing
ground noise abatement while in flight, passenger cabin
noise low due to aft engine locations.Efficiencies of operation derive from: 1) a low overall weight / revenue seat ratio, 2) large and adaptable passenger floor plans, 3) compatibility with existing ground terminal facilities, 4) multiple
engine configuration selections enabled by this aircraft
layout, both turbo-fan and turbo-prop, and 5) opportunities of growth within this configuration. It is a low wave-drag configuration that better approaches the cross-sectional frontal-area shape ideal for minimum drag at near
transonic speeds. This disclosure represents a general design concept and not a specific point design.
