A novel parachute and method of manufacturing can be performed quickly and inexpensively. The parachute comprises a canopy having a plurality of gores with interior and exterior sides, and a pocket on the interior side of the gores formed either with folded or gathered or folded and gathered material from the gore. Preferably, each gore is fastened to adjacent gores at two spaced locations to form longitudinal apertures between gores. When the parachute is deployed some air initially passes through the apertures. However, instead of acting as a single unit like a traditional canopy each gore initially inflates separately in the crown region. As the gores become inflated they work together to close the apertures between the gores and trap air as a single unit.
L'invention porte sur la voilure d'un parachute comprenant une pluralité de fuseaux (12), au moins un des fuseaux comprenant une poche d'ouverture (25), et sur un procédé de fabrication de cette voilure de parachute qui consiste à plier en deux une pluralité de fuseaux rectangulaires, parallèles à une paire de côtés longs (12A), chacun de ces fuseaux comportant deux côtés courts (12B) et deux côtés longs (12A); fermer hermétiquement un premier côté court de chaque pluralité de la pluralité de fuseaux de façon à former une poche d'ouverture dans chaque fuseau; raccorder et rapprocher la pluralité de fuseaux des poches d'ouverture et raccorder des coins adjacents d'un second côté court de la pluralité de fuseaux.
