In this study, to acquire design guidelines for future aerodynamic wingtip design with a wing grid, the aerodynamic coefficients of a planar wing with a wing grid and a rectangular wing, employing CRM.65.airfoil, at low- and high-Mach number conditions are compared using numerical simulation. As the result, the planar wing with a wing grid generates the extra induced-drag coefficient when the lift coefficient is the same. This is because the wingtip vortices of the wing grid occur, and the pressure coefficient on the first wingtip becomes especially smaller. Therefore, there is no advantage in these conditions with a wing grid when no proper dihedral angle or twist angle is set.
