Abstract
The conventional configuration of commercial aircraft composed by a tube fuselage, a cantilever wing, a vertical and a horizontal tail, has been improved since its introduction in the 1950s, and it is unlikely that big improvements should occur without drastic changes. The strut braced wing aircraft presents itself as an option. The main difference lies on a strut connecting the wing to the fuselage, reducing the bending moment of the wing and, consequently, its weight. Alternatively, the weight could be maintained constant while the wing span is increased and the wing thickness is decreased. This combination of geometric changes reduces drag and improves performance. A drag breakdown comparison is performed between the strut braced wing and the conventional aircraft configurations, based on a regional aviation mission. Parametric drag analyses on the strut braced wing configuration are conducted. Drag reductions of 12% are obtained when comparing the strut braced wing against a conventional aircraft of similar size, and 36% when comparing a high aspect ratio strut braced wing against a conventional aircraft.
