Abstract
A method for forming a parachute of a round configuration when deployed, and having a diameter D and a central vent of a diameter d, includes the steps of sewing together a plurality of elongated bolt widths of parachute cloth, the parachute cloth bolt widths being sewn together along lengthwise edges thereof to provide a sheet having seams interconnecting pairs of the bolt widths of cloth, the sheet having a width of about 1/2 D, less 1/2 d, cutting triangular pieces from the sheet, cutting opposite side edges of the triangular pieces to a length such that each side edge length is substantially equal to 1/2 D, cutting the triangular pieces from outboard edge ends to provide arc-shaped outboard edges, and sewing together the triangular pieces along the side edges thereof to produce main seams and to provide a round parachute canopy.
