The present invention relates to a heavy payload parachute ground disconnecting device. The device comprises an actuator (102) for keeping a holding mechanism (128) in a locked position during a predetermined time interval and after elapse of the predetermined time interval for releasing the holding mechanism (128) when a force acting on the actuator (102) is below a predetermined threshold. A latch mechanism (112, 122, 312, 412) releases a link assembly (110) connected to the payload when itself being released from the holding mechanism (128). In the holding position the latch mechanism (112, 122, 312, 412) transfers a predetermined portion of a payload force for acting on the actuator (102) within an operational range of the same. The device is highly advantageous by providing a simple, yet highly flexible, design for numerous payload ranges.

L'invention concerne un dispositif de déconnexion au sol de parachute à charge élevée. Ce dispositif comprend un actionneur (102) destiné à maintenir un mécanisme de retenue (128) en position verrouillée pendant un intervalle temporel prédéterminé. L'actionneur (102) permet de relâcher le mécanisme (128), lorsqu'une force agissant sur l'actionneur (102) est inférieure à un seuil prédéterminé. Un mécanisme de taquet (112, 122, 312, 412) permet de libérer un assemblage de liaison (110) relié à la charge, lorsque ce mécanisme est lui-même libéré du mécanisme de retenue (128). En position de retenue, le mécanisme de taquet (112, 122, 312, 412) transfère une partie prédéterminée d'une force de charge utile pour actionner l'actionneur (102) à l'intérieur d'un plage fonctionnelle de celui-ci. Le dispositif est fortement avantageux en ce qu'il permet d'obtenir une conception simple mais toutefois hautement adaptable à des plages de charge utile variées.
