Sport parachute, has space delimited by extension of inferior and superior walls of sheath with intermediate zone for passing wind in form of pocket to inlet duct

摘要

The parachute has sheath to collect wind and air flow. A space delimited by extension of lower and upper walls of the sheath has an intermediate zone for passing wind in form of pocket to one inlet duct. The duct has contraction from about one third of its length up to its opposite end. The duct reunites with another duct in an extension of each one of the ducts where the air flow crosses at their intersection. An independent claim is also included for a framework constituted of a shank assembly among them for forming a rigid assembly.
