Abstract : The upper and lower panel of a ram air inflated parachute canopy are connected interiorly of the canopy by lines extending between the panels at points spaced chordwise and spanwise of the panels so that airflow is unrestricted within the canopy and the weight and bulk of chordwise ribs is eliminated. The parachute suspension lines have connections to the lower panel at points where the interior lines connect to the lower panel and these connections may be made by loops incorporated in the lower panel. The interior line lengths and the proportions of spanwise end panels of the canopy may correspond to a triangular chordwise cross sectional shape of the canopy. The upper panel may have an extension forwardly of the lower panel with lines extending between the extension and the suspension lines to downwardly curve the extension and partially close the open forward end of the canopy.
