Abstract

L'invention porte sur une machine de débarquement aéroportée qui comprend un disque (2) d'enroulement de corde. Les modules rotatifs (4A, 4B) destinés à tourner en synchronisme sont disposés des deux côtés du disque d'enroulement de corde. Une manivelle (3.1) est montée entre les éléments rotatifs (4A11, 4B12) des modules rotatifs de manière à résoudre le problème du défaut d'uniformité des contraintes. Les éléments rotatifs unidirectionnels (4A3, 4B3) sont agencés pour résoudre le problème du ré-enroulement de la corde. Lorsque la corde (2.31) entraîne le disque d'enroulement de corde en rotation dans un sens sous l'effet de la gravité et entraîne la manivelle en rotation, la manivelle fait travailler un élément hydraulique limiteur de vitesse (3). L'élément hydraulique limiteur de vitesse est libre de fonctionner et la manivelle est libre de tourner lorsque le disque d'enroulement de corde tourne dans le sens inverse. La machine de débarquement aéroportée résout les problèmes de structure de contrainte irrationnelle de la manivelle de la machine de débarquement aéroportée à manivelle et piston limiteur de vitesse de l'état de la technique et de non divulgation de la technique du ré-enroulement de la corde. La machine de débarquement aéroportée évite aussi les défauts de danger potentiel pour l'utilisateur et les inconvénients.
