Title (EN) ELASTICALLY SUPPORTED THRUSTER STRUCTURE
(FR) STRUCTURE DE PROPULSEUR A SUPPORT ELASTIQUE
Abstract: front page image
(EN)The propeller thruster installation comprises a propeller unit (1) rigidly supported in an inner tunnel tube (2) which in its turn is elastically coaxially supported in an outer tunnel tube (6) which is rigidly secured to the hull (8) of the ship. In order to reduce the transmission of noise and vibrations from the propeller unit to the interior of the ship the annulus (7) between the outer and inner tunnel tubes is filled with elastic gas cushions (12), or a continuously maintained "bubble curtain" (12, 22) of air.
(FR)L"installation de propulsion à hélice comprend une unité à hélice (1) supportée de manière rigide dans un tube interne formant tunnel (2) qui est à son tour supporté coaxialement de manière élastique dans un tube extérieur formant tunnel (6) fixé de manière rigide à la coque (8) du bateau. Afin de réduire la transmission de bruit et des vibrations de l"unité à hélice à l"intérieur du bateau, le volume annulaire (7) entre les tubes extérieur et intérieur formant tunnel est rempli de coussins élastiques de gaz (12), ou d"un "rideau" de bulles d"air produit en continu (12, 22).
