Systems of the raising of a marine propulsion propeller of the ship has the effect of surface a keel lateral

摘要

The invention relates to a propeller driving system for a surface-effect ship with lateral keels able alternatively to navigate on the hulls and to navigate on an air cushion, and comprising, in the rear portion of each of the lateral hulls 1, 2 at least one marine propulsion propeller 9 driven by an engine installed in a fixed position inside the hull, this propeller being submerged during navigation on the hulls so as to propel the ship in this mode of navigation, and being out of the water when navigating on a cushion. According to the invention, the propeller is supported by a movable bearing interacting with means 30 for lifting the propeller suitable for moving it between a low position and a high position, corresponding to a condition for navigating on the hulls and navigating on a cushion respectively, an articulated transmission 20 being provided between the fixed portion, driven by the engine and the movable portion 12 supported by the movable bearing, of the propeller shaft.
