This report documents wind tunnel tests of a series of 20 gore Disk-Gap-Band parachutes to determine the effects off [sic] gap length, band length, band billow, and cloth air permeability on the parachute aerodynamic characteristics. Measurements for the steady-state drag-force, opening shock force, oscillation stability, and inflation stability were made of the various configurations and are presented in tabular and graphical format.
