Abstract

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, namely to the high-speed vessels propulsors. High-speed vessels propulsor is designed to ensure the ships movement at high speeds and is installed on the hull of the vessel with the flat bottom and engine. In the hull rear part cylinder is arranged with paddles located along its axis, surrounding the cylinder with paddles casing, rectangular box located under the bottom and covering the bottom paddles from the left, from the right and from below.

EFFECT: enabling increase in the propulsor efficiency.

Description

The invention relates to shipbuilding and can be widely used in the construction of high-speed vessels of all types.

As soon as the steam engine was invented, it began to be used as an engine for ships. And as a mover served huge wheels with blades (plates). These wheels have big disadvantages: they are bulky and heavy, dramatically increase the width of the vessel and worsen the stability of the vessel, interfere with mooring. Therefore, at the end of the 19th century, shipbuilders decided to switch to a traction screw, which has been known since Archimedes. Since then, no one doubts the advantages of the screw, but in vain. The screw also has several disadvantages:

1. During rotation, the screw rubs against water and a decent amount of power is spent on this friction.

2. The screw spins water and it also consumes power.

3. The part of the vessel adjacent to the propeller must be under water. This part pushes the mass of water and power is also spent on this expansion.

4. The screw is difficult to manufacture.

There are many attempts to develop propulsors for ships of a different design, but they have not found application. Even for gliders and hydrofoils, the same propeller is used as the propeller.

When completing this application, we reviewed many patents. All of them are very sophisticated, difficult to manufacture and do not solve the problem of creating high-speed economical vessels.

We believe that nothing more effective than a rowing oar has been created in the world. The first paddle wheels of steam vessels were like several oars connected at one point. The problem was that low-speed engines did not allow making these wheels small-sized.

As a prototype of the propulsion we offer, we take the wheels of the first steam vessels, but made taking into account the rotation speeds of modern engines and the achievements of modern technologies.

Propulsion device

The propulsion device is shown in Fig 1. In the rear of the hull there is a cylinder 2 with plates 3 located along the axis of the cylinder. The vessel 1 has a flat bottom and cylinder 2 is located so that at any given moment only the plates located in the lower part of the cylinder are located below the flat bottom of the vessel. A cylinder with plates is surrounded by a casing 4. The lower plates are closed on the left, right and bottom by a rectangular box 5 (to the plates) and 6 (after the plates). The rotation of the cylinder is carried out by the engine. The type of engine, its location, the type of transmission - may be different, therefore, they are not shown in Fig. 1.

Propulsion

The engine rotates the cylinder 2 with the plates 3. Water enters the front of the box 5 and 6. In the box, the plates 3 capture the water and throw it back. At the same time, boxes 5 and 6 do not allow water to move down, left and right, but directs it only backward. As a result, the reactive force of the water being thrown back to push the ship forward. When the vessel enters gliding, the entire hull of the vessel is above the water, and only the rectangular box 5 and 6 and the lower plates are in the water. These parts have very little resistance, so the propulsion efficiency is much higher than that of a screw.
