Abstract

La présente invention concerne les parachutes et plus particulièrement un dispositif de commande et d'assistance pour l'ouverture du parachute destiné à limiter le choc à l'ouverture qui se produit lorsqu'un parachute s'ouvre rapidement. Ce parachute est caractérisé en ce qu'il comprend une pluralité de cordes de prise de ris dont chacune est reliée à une suspente respective parmi l'ensemble des suspentes, en un point éloigné du point de convergence des suspentes, la corolle auxiliaire étant reliée aux cordes de prise de ris, le point où les cordes de prise de ris sont reliées aux suspentes principales étant suffisamment proche de la jupe de la corolle principale pour que, pendant le gonflage du parachute, la force exercée par la corolle auxiliaire sur les cordes de prise de ris produise un effet de prise de ris notable sur la corolle principale et que, lors de l'ouverture initiale, ces cordes de prise de ris déterminent la forme et la dimension de l'orifice d'entrée de la corolle principale
