Abstract

FIELD: shipbuilding.SUBSTANCE: invention relates to the field of shipbuilding and can be used for the construction of multi-hull vessels, in particular sailing trimarans and sailing ships with a large number of hulls. A multi-hull vessel is proposed, which contains a bridge combining side paired hulls and a central hull carrying the rigging, connected to the ship’s bridge by a hinge assembly sequentially to ensure the freedom of rotation of the central hull in the transverse plane in a wide range of angles when exposed to a lateral wind load on the rigging and excluding the transfer of the torque to the ship's bridge.EFFECT: counteracting the capsizing of a multi-hull sailing vessel with a strong lateral wind load impacting the rigging.3 cl, 5 dwg

Known sailing ship (patent: US 3807333 A, MCP B63B 1/14 // B63B 15/00 // B63B 39/00, publication date: 1974-04-30), the central body of which is connected by hinged nodes with a load-bearing frame that unites the elements propulsion system, consisting of sailing equipment, paired side hulls, keel.

The disadvantage of the known technical solution is that the lateral wind load is transferred from the sail rig to the propulsion unit, which, when the critical roll angle is reached, has negative stability and cannot resist the overturning of the vessel or its part.

The closest device to the proposed one in terms of the combination of features is a multi-hull base for a sailing vessel (patent: FR 2498551 A1, MCP B63B 1/14 // B63B 15/02, publication date: 1982-07-30) including bridge beams connecting the paired side hulls a multihull vessel, which is attached over the central hull of the vessel by means of hinge joints that provide the central hull carrying the sailing rigging freedom of rotation in the transverse plane of the vessel in the range limited by the bridge beams.

The disadvantage of the known technical solution, taken as a prototype, is the small permissible angle of rotation of the central hull in the transverse plane of the ship, bounded by the bridge beams, which does not allow to resist the overturning of the ship with a strong lateral wind load acting on the sailing rig.

The problem to be solved by the present invention is to counteract the overturning of a multihull sailing vessel with a strong lateral wind load acting on the sailing rig.

The task is achieved due to the fact that a multihull vessel, including a bridge that unites the side paired hulls and the central hull of the vessel, carrying the sailing rig, connected by means of a hinge assembly, the axis of rotation of which is above the center of gravity of the central hull, and providing freedom of rotation of the central hull in the transverse the planes of the ship, according to the invention, the central hull of the ship and the bridge of the ship are connected by a hinge joint in series.

In addition, the angle of rotation of the central hull in the transverse plane relative to the ship's bridge may be limited. In addition, the resistance to rotation of the central body in the transverse plane can be varied.

The invention is illustrated by the following drawings, where FIG. 1 schematically shows a multihull vessel in which the central body is located at the rear, front view. FIG. 2 is also a ship, top view. FIG. 3 also a multihull under the influence of the wind, front view. FIG. 4 shows a multihull vessel, in which the central body is in front, top view. FIG. 5 is a multihull vessel, in which the number of central hulls and bridges connecting side paired hulls is not limited, top view.

The multihull ship (Fig. 1) includes the ship's bridge 1, which unites the paired side hulls 2, connected in series by the hinge joint 3 with the central hull 4, on which the sailing rig is installed. armament 5, in the transverse plane in a wide range of angles.

A multihull vessel operates as follows.

In the initial state, all the hulls of the ship maintain the equilibrium position. The impact of the lateral wind load 6 on the sailing rig 5 creates a torque 7 on the central hull 4.

The serial connection of the hull 4 and the bridge 1 by the hinge joint 3 allows the central hull 4 to deflect in the transverse plane of the vessel in a wide range of angles. At the same time, the moment of rotation 7 is not transmitted to the bridge of the ship 1, and the bridge 1, connecting the paired side hulls 2, maintains its equilibrium position regardless of the effect of wind 6 on the sailing rig 5. When the wind load 6 on the sailing rig 5 decreases, the central hull 4 under the influence of the force of its gravity, it seeks to occupy a position of equilibrium.

Thus, the counteraction to capsizing of the vessel under the influence of the lateral wind load on the sailing rig is achieved due to the unobstructed deflection of the sail rig and the central hull in a wide range of angles, which excludes the transfer of the torque to the bridge of the vessel that unites the lateral paired hulls.
