CFD Analysis of Box Wing Configuration

Box wing configuration is an unconventional non planar configuration comparable to a conventional wing whose wings are connected on the tips by vertical wing-lets. In this way the wing configuration forms a rectangular box in the front view. The box wing configuration allows for savings in induced drag which results in reduced fuel consumption. To understand the basic aerodynamic features and their influence on box wing aerodynamics, CFD analysis is carried out based on various design parameters like height to span ratio and cant angle of box wing for optimum induced drag using ICEM CFD and ANSYS CFX solver. The design mission and geometry constraints of the reference aircraft are applied to the box wing aircraft so that performance and operational characteristics of both aircraft can be compared.
