Abstract

L'invention concerne un système de propulsion par jet d'eau variable comprenant un moteur, une pompe à hélice à pas variable montée dans un logement sphérique, un logement variable et un conduit d'entrée variable, ainsi qu'un microcontrôleur. La pompe, la buse et l'entrée sont commandés par le microcontrôleur. Ce microcontrôleur est programmé pour commander la pompe pour qu'elle fournisse une puissance variable de façon continue pour maintenir un fonctionnement efficace du moteur, pour commander la buse pour maintenir un fonctionnement efficace de la pompe, et pour commander le conduit d'entrée pour maintenir une récupération efficace de la hauteur manométrique totale de l'eau entrante. Le logement sphérique de la pompe est ajusté par rapport aux extrémités des pales de l'hélice pour un fonctionnement plus efficace du système à tous les pas, y compris à des pas nul ou inverses. Un pas nul ne produit aucune action de pompage et, par conséquent, une transmission de puissance hydraulique neutre. Un pas inverse combiné à une grande buse variable produit un écoulement inverse et, par conséquent, une poussée inverse, ce qui permet d'éviter l'utilisation d'un <= auget >= pour dévier la direction d'écoulement du fluide.
