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 39 m (127 ft).  That's too long for the SUGAR Volt to be accommodated at standard airline gates, so the outer wing is hinged for folding.  To achieve high 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.

Let us imagine a SUGAR Volt airliner configured for markets now served by Boeing 737s, the highest-selling airliner in history, with more than 10,000 in service as of this writing.  The table below makes technical comparisons based on [a] specifications for the Classic version of the Boeing 737, [b] reference literature for the SUGAR Volt and [c] an elementary model...
