ABSTRACT:
A reserve parachute for deployment under low descent speeds includes a rubber ring packed with the canopy and rigging lines and attached to the canopy in the region of the canopy apex and being disposed concentric with respect to a vent hem of the canopy. Upon deployment the ring expands to increase profile drag to ensure the canopy mouth faces substantially downwardly during deployment. The peripheral hem of the canopy at the canopy mouth is stiffened with a tape loop treated with polyurethane so that the peripheral hem springs apart upon deployment. An inhibitor tie is attached to a loop of the folded rigging lines within the pack to permit only a part of the rigging to be released initially; the inhibitor tie breaks at a predetermined tension in the lines to permit the remainder of the rigging lines to be released and to permit fully canopy deployment.
