  • the invention relates to a hull structure, in particular to an energy-saving high-speed hovercraft hull. Background technique
  • the resistance of an object moving in water to water is greater than the resistance to air movement, because the density of water is about eight hundred times that of air, so that the resistance of an object moving in water is about eight hundred times that in air.
  • the reason why the ship does not run fast in the water is the resistance of the water. When the ship runs fast, the resistance of the water also increases sharply. The water resistance hinders the speed of the ship. According to the experiment, there are three parts to the speed of the ship. The first is the friction force, which is generated by the friction between the surface of the hull and the water flow. The larger the area of the hull contacting the water, the greater the frictional resistance.
  • the second is the wave resistance, the waves that the ship sails in the water form resistance; the third is the eddy resistance.

One is to increase the power; the other is to reduce the resistance; the increase in power will increase the consumption of machinery and fuel; the most effective way to greatly improve the speed of the ship is to let the hull go out of the water. Get rid of water resistance, which can increase the speed of the ship and save fuel.
  • the bottom of a traditional ship is sealed. It must overcome the resistance of water when sailing, and consume a lot of energy.

节能型髙速气垫船船体 技术领域
本发明涉及一种船体结构， 尤其是指一种节能型高速气垫船船体。 背景技术
物体在水中运动受到水的阻力要比在空气运动的阻力来得大， 因为水的密度约 为空气密度的八百倍， 这样物体在水中运动时的阻力大约为在空气中运动的八百 倍。 船舶在水中之所以跑不快， 就在于水的阻力， 当船舶跑快了， 水的阻力也承之 急剧增加， 水阻力阻碍船舶速度的提高； 根据实验证明， 水对船舶的速度阻碍有三 部分， 一是摩擦力， 它是由船体表面与水流摩擦而产生， 船体接触水的面积越大， 摩擦阻力越大。二是兴波阻力， 船在水中航行兴起的波浪形成阻力； 三是涡流阻力， 船航行时， 船尾引起的涡流形成阻力， 它与船舶的形状有关， 叫形状阻力。 要提高 船速有两条途径， 一是增加动力； 二是减小阻力； 增加动力会增加机器和燃料的消 耗； 要大幅度提高船舶的航行速度， 最有效的办法是让船体大面离开水面， 摆脱水 阻力， 既可提高船的航速， 又能节省燃油。 传统船舶的底部是密封的， 航行时要克服水的阻力， 需要消耗大量的能源； 船 的吃水越深， 航行时的阻力越大； 为减小船舶的航行阻力， 通常将船的横截面设计 成 V形或近似 V形， 以减少水阻、 提高航行速度， 但通常船舶的航行速度不超过 30 节。 在此基础上， 经过人们的不断努力， 发明了气垫船， 气垫船通过在船体两侧或 底部设置充气垫， 航行时再向气垫内充气， 将船体升高贴近水面， 利用两侧的翼刀 进行稳定， 大大减小了航行时水的阻力， 船速可以提高到 40-60节； 但气垫船也存 在在致命的缺点， 因需对气垫进行冲、 放气， 结构复杂， 受发动机功率的影响， 使 得气垫船的载重量受到很大的限制， 一般只能承载几百吨， 同时其能源消耗惊人， 只能用于短途人员运输、 军事运输等特殊场合使用。 发明内容
本发明要解决的技术问题是提供一种安全、 稳定、 快速、 航行阻力小， 结构简 单、 生产成本低的节能型高速气垫船船体。 本发明的技术方案是： 一种节能型高速气垫船船体， 包括船体， 其中所述船体 的船底中部是向上凹的凹底， 在该凹底上设有至少两个密封气舱和至少一个向下敞 开的气舱。 上述的节能型高速气垫船船体中所述船体上设有空气增压装置， 空气增压装置 的高压出口分别与各气舱连通。 上述的节能型高速气垫船船体中所述凹底上的密封气舱与船头底部交界 处设有前滑动辊轮。 上述的节能型高速气垫船船体中所述凹底上的密封气舱和气舱与船艉底部交 界处设有后滑动辊轮。 本发明采用上述结构后， 通过船体底部采用以密封气舱与向下敞开的气 舱相结合的设计， 与常规船舶相比， 船体重量减轻， 浮力增加、 简化了船体 的结构， 易建造， 减少船体底部与水的接触面积， 降低水的粘滞阻力， 降低 能源消耗； 同时船体底部的密封气舱增加船体横向稳定性、 结构坚固性， 使 船体的稳定性更好， 更安全、 不翻侧； 气舱承载船体吃水浅， 提速容易， 航 速快； 本发明的船体经实际反复实验， 比同等载重的气垫水翼型船节约燃油
60-80%, 降低运输费用 50%以上， 提高运输效率 10倍以上， 船速可提高到 90~100节 /小时， 甚至更高， 广泛用于民用运输或军事用途， 具有巨大的经济 效益和社会效益。 附图说明
