Problems solved by technology

If the resistance peak value is too high, it will increase the load of the main engine. In severe cases, the hull will always be in the peak climbing stage, which will affect the use of the ship

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The present invention provides an air curtain bow seal structure, in particular an air curtain bow seal structure that improves the peak performance of an air cushion catamaran, and is also suitable for local air cushion catamarans. The structure is located at the bow of the wet deck of the connecting bridge. Open a row of fine inflatable holes or a long and thin air slit, and inflate the dense small holes or air slits through a high-pressure fan to form a sealing film similar to an air curtain, which can not only seal the air in the air cushion cabin The gas also eliminates the water-pushing resistance caused by the bow sealing device touching the water, and the present invention reduces the resistance peak value on the whole, and achieves the purpose of improving the peak-crossing performance of this kind of ship.

Abstract

The invention provides an air-curtain bow sealing structure. Through the adoption of the air-curtain bow sealing structure, the peak surpassing performance of a partial air-cushion supported catamaran is improved. According to the structure, a row of fine small air inflation holes or a slender air seam is formed in the bow of a wet deck of a connection bridge; a high-pressure fan inflates the fine small holes or the air seam, so that a sealing membrane similar to an air curtain is formed; the air membrane can seal the air in an air cushion chamber, and can also eliminate water pushing resistance generated by the contact of a bow sealing device and water. Through the adoption of the air-curtain bow sealing structure disclosed by the invention, the resistance peak is generally reduced, so that the purpose of improving the peak surpassing performance of ships is realized.

Description

technical field [0001] The invention relates to a structure for improving the resistance performance of a ship, in particular to an air curtain bow seal structure, which can change the form of the air seal at the bow of an air cushion catamaran to reduce running resistance and improve its peak performance. Background technique [0002] The air-cushion catamaran combines the advantages of the full lift hovercraft and the ordinary catamaran, with fast speed, good stability, low power consumption, and because of its large deck area, it is easier to develop into a large-scale one. Generally speaking, the air cushion catamaran has two resistance peaks, primary and secondary. At the peak of the main resistance, due to the wave-making of the air cushion generated by the apron touching the water, a trough appears in the forward part of the voyage, and the trough is lower than the plates on both sides, so that high-pressure gas escapes, resulting in a pumping phenomenon. The pumping...
