Title (EN) DRIVE MEANS IN A BOAT
(FR) MOYENS D'ENTRAINEMENT POUR BATEAU
Abstract: front page image
(EN)Boat propeller drive with an underwater housing which is connected in a fixed manner to a boat hull and has tractor propellers which are arranged on that side of the housing facing ahead and the blade areas of which are adapted to one another in such a manner that, at least under certain operating conditions, the aft propeller works in a cavity-generating manner whereas the fore propeller works in a cavitation-free manner.
(FR)L'invention concerne une unité d'entraînement pour hélices de bateau, dont le carter immergé est relié de façon fixe à la coque du bateau. Ladite unité comporte, en outre, des hélices tractives disposées sur le flanc avant du carter, hélices dont les pales sont agencées les unes par rapport aux autres de telle manière que, tout du moins dans certaines conditions de fonctionnement, l'hélice arrière fonctionne de manière à créer des cavités alors que l'hélice avant fonctionne sans cavitation.
