Strut-braced wing (SBW) can contribute to reducing regional aviation's environmental impact. However, trade-offs emerge, with increased parasite drag compensated by lower induced drag and wing weight. The paper proposes a parametric model to consider the induced drag penalties in the preliminary design stage. The potential reduction in mission fuel consumption is estimated for the ATR 72-600.
