Abstract
UN PROPULSEUR CAPABLE DE DEVELOPPER UNE POUSSEE IMPORTANTE A FAIBLE VITESSE ET TOTALEMENT IMMERGE COMPORTE DES PALES ENTRAINEES PAR UNE CHAINE D'ENTRAINEMENT, TENDUE ENTRE DEUX ROUES DONT LES FACES DETERMINENT UN PLAN DE REFERENCE. CES PALES ORTHOGONALES AUDIT PLAN DE REFERENCE, QUI SONT LIBRES EN ROTATION AUTOUR DE LEUR MANCHON ET ENCASTREES PAR CE MANCHON DANS LA CHAINE D'ENTRAINEMENT, PRESENTENT AU MOINS UNE CAME DISPOSEE SUR LEUR MANCHON, POUR UN APPUI SUR AU MOINS UN RAIL LATERAL.A THROTTLE CAPABLE OF DEVELOPING SIGNIFICANT THRUST AT LOW SPEED AND TOTALLY SUBMERSIBLE HAS BLADES DRIVEN BY A DRIVE CHAIN, TENSIONED BETWEEN TWO WHEELS, THE FACES OF WHICH DETERMINE A REFERENCE PLAN. THESE ORTHOGONAL BLADES AUDITED REFERENCE PLAN, WHICH ARE FREE TO ROTATE AROUND THEIR SLEEVE AND RECESSED BY THIS SLEEVE IN THE DRIVE CHAIN, HAVE AT LEAST ONE CAM ARRANGED ON THEIR SLEEVE, FOR SUPPORT ON AT LEAST ONE SIDE RAIL.
