Vessel propulsion plant

FIELD: engines and pumps.

SUBSTANCE: invention relates to shipbuilding, namely to a vessel propulsion plant. The vessel propulsion plant has a hull (10) with a midship part (12) and aft part (14). The plant comprises two propulsion units (30, 301), the units are fixedly secured on the hull (10) at both sides of the hull center line (10) and on specified aft part (14). Each of the propulsion units (30, 301) comprises a housing with propeller (48) of outside surface of the housing. The housing further determines internal space, where drive mechanisms (52, 54, 56) are installed to rotate propeller (48) by the propeller shaft (46), and additionally comprises opposite internal (14) and outside (42) sides. The internal space is connected with internal part of the hull (10), and internal (44) and outside (42) sides are connected in the fore part of the propulsion unit along front edge (36) of the vessel. The vessel comprises the propulsion plant. Also comprises a method of the hull (10) reequipment using the propulsion plant.

EFFECT: document describes design and operation of the vessel propulsion plant.

SUBSTANCE: invention relates to ship building, particularly, to ship after equipped with propulsive-steering gear arranged outside the ship hull. Ship after is equipped with crinoline. Crinoline deck has opening closed by detachable platform for propulsive-steering gear to be secured thereat. Guide posts are arranged along the edges of said opening with their top ends rigidly coupled with the bracket attached at ship hull.

EFFECT: improved operating and servicing conditions.

FIELD: transportation.

SUBSTANCE: suspension comprises screw-clamp arranged in the form of doubled bracket installed on vessel transom. Two parallel guides are fixed to screw-clamp, in lower part of which carriage is installed, movable in vertical direction. Carriage has horizontal joints, with the help of which it is connected to side screw-clamps rigidly fixed on sheer clamps of speedboat. Hydrojet engine of speedboat has remote control from vessel.

EFFECT: unification of screw-clamp with serial suspended engines, simplified of speedboat suspension design.

SUBSTANCE: this boat comprises hull, three keels composed of wheel units. Tow keels are locates at boat aft in symmetry about its lengthwise axis while third keel is arranged at boat lengthwise axis centre. Wheel unit comprises three wheels secured in cantilever regularly and in symmetry about rotational axis to run along the boat lengthwise axis. They feature equal size and different weight. Two of said three wheels have maximum and minimum weight while third one features average magnitude of both.

EFFECT: ease of motion on ground, higher speed in shallow water, better heading stability.
