Short abstract: The balance of induced and parasite drag and the rollup process of wingtip vortex from a NACA 0012 wing was affected by allowing the freestream to pass through chordwise slots connecting the leading and trailing edge of the wing at multiple spanwise locations. Three wing configurations, one with 8 slots equally spaced, the second with 11 slots elliptically spaced (resembling lift distribution), and the third without any slots were tested at the University of Dayton Low-Speed Wind Tunnel (UD-LSWT).
