Title (EN) GLIDE MODULATOR SYSTEM AND METHOD FOR A RAM AIR PARACHUTE
(FR) SYSTÈME DE MODULATEUR DE GLISSE ET PROCÉDÉ POUR UN PARACHUTE À AIR DYNAMIQUE
Abstract:
(EN) A system and method is provided for shortening specific suspension lines near the center of a ram air parachute in order to distort the airfoil section only in the center section of the canopy. This distortion of the center section results in a significant alteration of the glide ratio of the parachute by simultaneously reducing the forward speed and increasing the rate of descent. Meanwhile, because the canopy is only distorted in the center section, the wingtips remain extended and pressurized so that the steering apparatus at the trailing edge of the canopy remains fully functional to direct the heading.
(FR) L'invention concerne un système et un procédé pour raccourcir des lignes de suspension spécifiques à proximité du centre d'un parachute à air dynamique afin de déformer la section de surface portante uniquement dans la section centrale de la voilure. Cette déformation de la section centrale conduit à une modification significative du rapport de glisse du parachute en réduisant simultanément la vitesse d'avance et en augmentant la vitesse de descente. Par ailleurs, étant donné que la voilure n'est déformée que dans la section centrale, les extrémités de l'aile restent étendues et sous pression de telle sorte que l'appareil de direction au niveau du bord de fuite de la voilure reste totalement fonctionnel pour contrôler le cap.
