Abstract:
1. In combination with a ram air parachute canopy having upper and lower airfoil surfaces separated by chordwise-extending ribs to form cells inflated by inflow of air at an open leading edge, and suspension lines connecting the lower surface of the canopy to a load, the improvement comprising: a generally rectangular reefing slider having corner grommets and a plurality of intermediary grommets spaced between said corner grommets through which the suspension lines extend, said slider further having a plurality of separate retaining devices each adjacent one of said grommets and secured to said canopy for retarding descent of the slider relative to the canopy from an upper reefing position in which inflation of the canopy is restricted, said slider being releasable from said canopy to descend along said suspension lines in response to release of said retaining devices due to force created by said inflow of air to said cells, said retaining devices including slider retaining loops respectively secured to said slider adjacent each retained grommet, canopy retaining loops secured to said canopy in spaced relationship corresponding to a spacing of said retained grommets, and fastening elements for securing said slider retaining loops to said canopy retaining loops in corresponding pairs.
