The SUGAR Volt applies the Boeing Truss-Braced Wing in a future design concept for a subsonic, electrically powered airliner in response to a request for aircraft research proposals by NASA

The key aerodynamic feature of the SUGAR Volt is its extremely high aspect ratio of 27, using a wingspan of 127 ft (39 m).  That's too long for the SUGAR Volt to be accommodated at standard airline gates, so the outer wing is hinged for folding.  For aerodynamic efficiency, the wing must be both slender and thin, so the design applies a truss-braced configuration.  The truss has the form of an airfoil, which provides lift to augment that of the wing.
