Example Embodiment

[0018] As shown in the picture: the waterway water littoral combat ship is composed of the lower part of the hull 1, the bottom plate 4 and the two side cabins 3 arranged in parallel to form a rectangular rectangular bottom cabin. The cabins 3 on both sides are a hollow structure with flat outside and convex inside, and both ends are acute angles. The middle cabin 2 is a streamlined hollow body with a length smaller than that of the bottom plate 4. The gap between the middle cabin 2 and the side cabin 3 is the water passage 6. A propeller 7 is arranged in the middle of the water passage 6, and the two ends of the rectangular cuboid bilge are respectively rectangular water inlets 5 and water outlets 8. The lower sides of the water inlet 5 and the water outlet 8 are the bottom plate 4, the sides are the acute-angled points of the cabins 3 on both sides, and the upper side is the lower part of the hull 1. The upper edges of the water inlet 5 and the water outlet 8 are lower than...

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 repel water to provide power is the basic power mode for realizing ship movement under the prior art. There are following obvious deficiencies and defects in this power mode: in theory, the advance of ship equals the thrust of propeller minus the resistance of hull. In practice, more complicated factors are included. First, the water-repelling process of the propeller will cause a negative pressure zone with a large-angle cone in front of the rotating propeller, and a negative pressure zone with a small-angle cone in the rear. In the positive pressure 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 negative...
