Problems solved by technology

The storm torpedo that uses air bubbles (actually a kind of air cushion) to reduce drag, although it moves extremely fast, needs to use a lot of energy, so it severely limits the shape, weight and range of the torpedo when using this technology
As for the application of this type of air cushion drag reduction technology on the top of other ships and submarines, until now there have been no truly mature and complete specific application reports

Embodiment Construction

[0026] In various torpedoes, the entire outer surface of the front rectifying cone of a submarine, part or all of the outer surface of the rear of the cone, and the most forward surface of the part below the water surface line of various ships, as well as the rear or lower part of it Part or all of the surface, the installed jet-type drag-reducing jacket is provided with a gas-moving gap (2) jet-type drag-reducing jacket (1) shell layer on the outer surface; , and the rib-shaped support strips (3) between the outer surfaces of the ship; and the internal space of the drag-reducing coat between different rib-shaped support strips; installed in torpedoes, submarines, ships, and high-speed ships. To provide the air required for the work of the jet-type drag-reducing jacket, it can be composed mainly of a large-scale booster blower (6), or a high-temperature and high-pressure gas generation engine (30), or the main engine jet port.

Abstract

The invention provides a resistance-reducing technology mainly based on gas cushion resistance reduction. The resistance-reducing technology is characterized by installing resistance-reducing outer cover devices on the outer surfaces of parts, in contact with water bodies, of torpedoes, submarines and high speed surface ships. Gas jet-type resistance-reducing outer covers (1) are installed on the outer surface of the most front rectifying cone area of a torpedo and a submarine or all the outer surface of a torpedo body and a submarine body, and the front portion, the front lower portion and all the surface of the part below the water surface line of a high speed ship. The working gas of the gas jet-type resistance-reducing outer covers is provided by a pressure-jump booster fan (6) arranged in the torpedo body, the submarine body and the ship body or at the upper portion of the ship surface or a special gas yield engine (30) capable of generating high temperature and high pressure gas, or is provided by gas jet of a main engine of the torpedo and the submarine.

Description

Technical field: [0001] The invention relates to a drag reduction technology that can be applied on the outer surfaces of torpedoes, submarines and surface warships. Background technique: [0002] Although the air-cushion drag reduction technology has some applications in the upper part of torpedoes, submarines, and surface ships, in the air-cushion drag reduction technology applied to ships, the hovercraft can only travel on the upper surface of the water, and it needs to use a large amount of air supply. So it is impossible to make it very large. The storm torpedo that uses air bubbles (actually a kind of air cushion) to reduce drag, although it moves extremely fast, needs to use a lot of energy, which severely limits the shape, weight and range of the torpedo when using this technology. As for the application of this type of air cushion drag reduction technology on the top of other ships and submarines, there have not been any really mature and perfect specific applicati...
