Abstract
1419546 Ships' bow thruster units PLEUGER UNTERWASSERPUMPEN GmbH 6 Feb 1973 [15 Feb 1972] 5723/73 Heading B7V A ship's bow thruster unit comprises a circular section propeller tube which is within, or which shares a common wall with, a pressure equalizing tunnel and which is offset in a forward direction relative to the tunnel. Fig. 4 shows the first arrangement. The tube 2 may be offset to the point where it contacts the tunnel 4, Fig. 5 (not shown). Fig. 8 shows an example of the second arrangement. The tube and tunnel ends at each end of the thruster unit may lie on a dished notional surface, Fig. 9 (not shown).
