Abstract

L'invention concerne une turbine à énergie éolienne à matériau à changement de phase thermique solaire sur des paliers de lévitation magnétiques. Les paliers de lévitation magnétiques ou des systèmes de couplage (4a) et (4b) couplent deux ou plusieurs tubes alignés de façon concentrique en logeant les composants magnétiques dans les tubes assemblés (1) qui forment des structures de tube à groupe de construction hexagonale courbé (1) qui se verrouillent ensemble dans des structures de tubes concentriques. Cet écoulement d'air est conçu dans le système pour un fonctionnement 24h sur 24 de l'éolienne (2), où le soleil fournit une large différence de température entre des températures pendant le jour et pendant la nuit. Un appareil pour groupe de construction de tube (1) avec des couplages de lévitation magnétique ou des systèmes de palier (4a) et (4b), et plus spécifiquement des groupes de construction remplis de matériaux à changement de phase qui absorbent l'énergie solaire thermique pendant le jour afin qu'une source d'énergie thermique puisse entraîner une turbine en soufflerie à faible vitesse (2) pendant la nuit à partir des différences de température; l'air intérieur, sensé déplacer vers le haut le tube (1), à une température supérieure à celle de l'air extérieur, déplace vers le haut le tube (1) après récupération de la chaleur stockée par les matériaux à changement de phase (11) qui ensuite entraînent le générateur électrique à turbine (2) ayant subi une lévitation par des paliers magnétiques (4a) et (4b). Le même appareil pour groupe de construction de tube avec des couplages à lévitation magnétique ou des systèmes de palier fournit aux assemblages aérospatiaux un moyen de lévitation afin de maintenir ensemble le fuselage, l'aile, et les composants de propulsion à leur place, sans connexion physique, et les sollicitations sur le cadre du fuselage. Ces composants aérospatiaux peuvent être facilement échangés avec d'autres composants afin d'obtenir des différentes performances aérodynamiques.
