For more than five years, the Multidisciplinary
Analysis and Design Center for Advanced Vehicles,
under a grant from NASA Langley Research Center,
worked on multi-disciplinary analysis and design of a
large Strut-braced wing aircraft with the same capacity
as the Boeing 777. It was seen that using a strut can
significantly improve the fuel efficiency and thus
results in a considerable fuel weight saving. (2002)
The above figure shows some of the advanced concepts
that were considered to design efficient large
transport airplanes using the strut-braced concept.
The presence of a ring-type wing can considerably
reduce the induced drag thus greatly reducing the fuel
consumption. (2002)
