Wave-piercing type side wall hovercraft

Abstract

The invention discloses a wave-piercing type side wall hovercraft which comprises a hovercraft body, a front apron, a middle apron, a rear apron and air cushions arranged among the front apron, the middle apron and the rear apron, wherein the front apron, the middle apron and the rear apron are arranged on the lower portion of the hovercraft body. The flat bow design of a traditional air bag typeapron and a ship body is thoroughly changed, the ship bottom is designed to be a variant quadruple ship, the traditional air bag type apron is replaced with the jet type apron, high-frequency vibration of sailing under the sea condition is overcome, and sailing stability under the set sea condition can be achieved; the problem of air leakage between the apron and the water surface is solved, and air supplementing energy consumption is reduced; the lifting pressure is increased, so that the displacement is greatly improved; wave-making resistance of waves to the ship is reduced through wave-shaped design navigation of the prow, the navigation adaptability on the sea surface is further optimized on the basis of a side wall hovercraft, and the sea condition navigation level is improved.

Description

technical field [0001] The invention belongs to the field of sidewall hovercraft, in particular to a wave-piercing sidewall hovercraft, which is mainly used for navigation stability, increased displacement and energy saving in sea conditions. Background technique [0002] Since the advent of sidewall hovercraft, through decades of development, there have been many types of sidewall hovercraft, which are used internationally for military operations and special tasks due to the high speed of sidewall hovercraft. The typical ones are the former Soviet Union's "Bulafeng Missile Boat" and the Swiss "Smig" class sidewall hovercraft. The "Bulafeng Missile Boat" has a standard displacement of 750t and a full load displacement of 1050t. Between 10.5kPa, the speed reaches 45kn-55kn, and the energy consumption for boosting air is 6600 horsepower. In the sea state, the navigation vibration is large, the stall is large, and the high-frequency vibration will cause sequelae to the operator...

AI Technical Summary

Problems solved by technology

[0005] The present invention is a further improvement on the existing level of the side wall hovercraft, especially the widened range of use, and is more suitable for use in sea conditions, aiming at the problem of high-frequency vibration and water surface gaps caused by the over-peaking of the front and rear airbag aprons in sea conditions The technical difficulty that air leakage cannot be sealed, provides a unique spray sealing technology, which solves the air leakage problem that cannot be solved by the air bag apron to the water surface gap, the high frequency vibration problem of the air bag apron, and greatly reduces the pad lift air leakage reduce the energy consumption of the air, effectively increase the pressure of the pad lift, can change the status quo of the small displacement of the hovercraft, and provide technical conditions for the development of large displacement to adapt to sea conditions.

Aiming at the problems of high-frequency vibration and high water pushing resistance caused by the existing bow aprons over the peak, poor wave resistance, air leakage between the bow and tail aprons and the water surface, small displacement and the design problems of the traditional flat bow, a sealing is provided. , wave-absorbing, wave-piercing hull, stable navigation in sea conditions, low energy consumption, and a sidewall hovercraft with a hull structure of high cushion lift pressure, which improves the shape of the hull to adapt to sailing in sea conditions. Features, more suitable for sailing in sea conditions;

[0006] The invention provides a jet-type apron, which is more suitable for navigating in sea conditions. Aiming at the problem of high-frequency vibration caused by the head and tail airbag-type apron over the peak in sea conditions, and the high-frequency vibration problem of the airbag-type apron, the existing first The problems of high-frequency vibration and high water pushing resistance caused by the apron jumping over the peak cannot be solved, and the design problems of poor seakeeping capability, small displacement and traditional flat bow provide a jet-type apron, wave-piercing hull that is stable in sea conditions, low-energy The sidewall hovercraft with low-cost hull structure improves the shape of the hull to adapt to sailing in sea conditions. The purpose is to not only have the functions of a hovercraft but also maintain the characteristics of a surface ship, and better meet the needs of sailing in sea conditions.
