Abstract

L'invention porte sur un appareil à propulsion interne d'un système fermé au moyen de la force de Coriolis, qui permet de générer du mouvement sans force externe. L'appareil à propulsion interne comprend : un corps fermé (10) dont l'intérieur est creux ; un élément de guidage (72) pourvu d'une pluralité de fentes le long de la forme cylindrique de sa surface latéral, l'élément de guidage (72) étant disposé à l'intérieur du corps (10) et placé de manière excentrée par rapport au centre du corps (10) ; un moteur (71) placé au centre du corps (10) et perpendiculaire à l'élément de guidage (10) ; une pluralité de rayons (39a) qui sont reliés vers l'extérieur et dans le sens radial à l'extrémité d'arbre du moteur (71) afin de pivoter autour du moteur (71), les rayons (39a) étant perforés à travers les fentes de l'élément de guidage (72) et disposés radialement autour de l'élément de guidage (72) à intervalles réguliers ; et une pluralité de masses de noyau (63-70) disposées dans chaque cloison et restreintes par les rayons (39a) et l'élément de guidage (72). Ainsi, l'appareil à propulsion interne fonctionne non seulement dans un champ gravitationnel, mais aussi dans un état de vide sans gravité, ce qui est un avantage en vue de l'ère spatiale à venir, grâce à l'utilisation de la force de Coriolis (Fc) dans un système fermé.
