Abstract

L'invention porte sur un système de propulsion à palettes, qui est constitué d'au moins trois palettes (1), placées au-dessus et/ou au-dessous du bras de support (3), tandis que chaque palette est fixée en partie dans au moins un pivot séparé (4) de façon à pouvoir pivoter. Des pivots (4) sont placés sur les bras de support (3) et une extrémité de chaque bras de support (3) est fixée de façon radiale sur le corps de collecte (2) de couple. Les axes des pivots (4) sont parallèles à l'axe longitudinal de leur bras de support (3). L'axe du corps de collecte (2) de couple est perpendiculaire à l'axe longitudinal des bras de support (3). Le plan de course de chaque palette (1) est parallèle à l'axe longitudinal du bras de support (3). L'angle d'ouverture de chaque paire de palettes (1) est de 0 ° à 180 ° et de 0 ° à 190 ° pour une palette séparée (1).
