Problems solved by technology

There are the following obvious deficiencies and defects in this power mode: theoretically speaking, the advance of the ship is equal to the thrust of the propeller minus the resistance of the hull
But this improvement does not change the basic power mode of ship movement under the existing technology

Embodiment Construction

[0018] As shown in the figure: the waterway waterfront combat ship is composed of the lower part of the hull 1, the bottom plate 4 and the side cabins 3 arranged in parallel to form a cuboid bottom tank. The cabins 3 on both sides are hollow structures with flat outside and convex inside and two ends with acute angles. The middle cabin 2 is a streamlined hollow body whose length is shorter than the bottom plate 4 . The gap between the middle cabin 2 and the side cabin 3 is a waterway 6 . A propeller 7 is arranged in the middle part of the water passage 6, and the two ends of the cuboid bilge are respectively a rectangular water inlet 5 and a water outlet 8. The bottom of the water inlet 5 and the water outlet 8 is the bottom plate 4, the sides are the acute-angled tip of the tanks 3 on both sides, and the top is the bottom of the hull 1. The top of the water inlet 5 and the water outlet 8 is lower than the water surface 9 .

Abstract

The invention provides a water-channel water-returning littoral combat ship and belongs to military equipment. The water-channel water-returning littoral combat ship comprises a ship body, a middle cabin, a lateral cabin, a base plate, a water inlet, a water-passing channel, a propeller and a water outlet, and is characterized in that: a bottom cabin is a rectangular cube; the water-passing channel with four surfaces being closed is arranged in the rectangular cube; the propeller is arranged in the water-passing channel; and water passes through the water-passing channel from the water inlet and is removed from the water outlet, so as to realize the advancing of the combat ship. Compared with the prior art, the water-channel water-returning littoral combat ship has the advantages of simple structure, adaptation to fluid mechanic law, small resistance, high speed, shallow drafting, silence, small target, wide moving area, strong adaptive capacity and excellent popularization and application values.

Description

1. Technical field: [0001] The invention relates to military equipment, in particular to a combat ship on the waterfront of a waterway. 2. Background technology: [0002] Relying on the propeller mounted on the rear and lower part of the hull to drive water to provide power is the basic power mode to realize the movement of the ship under the prior art. There are following obvious deficiencies and defects in this power mode: in theory, the advance of the ship equals the thrust of the propeller minus the resistance of the hull. In practice, more complicated factors are involved. First, the water repelling process of the propeller will cause a large-angle cone-shaped negative pressure area in front of the rotating propeller, and a small-angle cone-shaped positive pressure zone in the rear. In the jet area, the decreasing high-speed flow of the water body in the jet area also forms a negative pressure area compared with the surrounding water body. The existence of this negati...
