We investigate the aerodynamic efficiency and flight dynamics of mono-wing and box-wing
configurations across various parameters, including aspect ratio, velocity, and lift requirements.
We find that although mono-wing configurations exhibit superior aerodynamic efficiency in
certain regimes, box-wing designs perform better in circumstances like high velocities and
increased lift demands. Box-wing configurations also prove advantageous when induced drag is
higher than friction drag due to their ability to suppress the tip vortices. Furthermore, while
analyzing the flight dynamics, low aspect ratio box-wing configurations show improved gust
tolerance and stability in longitudinal and lateral dynamics. However, no substantial difference
in flight dynamics is observed between box-wing and mono-wing designs for high aspect ratio
configurations. The findings underscore the importance of selecting the appropriate wing
configuration based on specific performance requirements and operational conditions.
