Abstract

本发明公开了一种由船体(1)、叶片(2)和螺母(2)组成的带孔式战舰,叶片(2)由螺母(3)固定在船体(1)上,叶片(2)上开有孔。采用以上方法后,当叶片转动后,水会从该孔中流到叶片(2)背面压区,原来负压区被水充满,负压不存在了,叶片(2)内回流和旋涡减少,消耗动力减少,工作效率提高。

Description

带孔式战舰
本发明涉及在水中航行的战舰。如护卫舰、航母和潜艇等。
已有的战舰在水中航行时,通过转动螺旋浆,螺旋浆的叶片将水向后推,战舰靠水的反作用力将其向前推,达到船舶向前航行的目的。因为在螺旋浆高速转动过程中,叶片正面受压,而背面形成负压,其负压区域又形成回流和旋涡,该回流和旋涡影响水的流动,消耗动力,降低工作效率。
本发明的目的就是提供一种无负压、少回流的旋涡的带孔式战舰。
为了达到以上目的,本发明的带孔式战舰的技术方案为:在叶片上开有孔。
采用以上方案后,因为在叶片上开有孔,水从该孔中流到叶片背面负压区,原来负压区被水充满,负压不存在,叶片内回流和旋涡减少,消耗动力减少,工作效率提高。
下面用附图和实施例对本发明的带孔式战舰作进一步说明。
附图1为本发明带孔式战舰第1实施例结构总图。
附图2为本发明带孔式战舰第1实施例局部放大图。
在附图1和附图2所示的第1实施例中,本发明的带孔式战舰由船体(1)、叶片(2)和螺母(3)组成,叶片(2)由螺母(3)固定在船体(1)上,叶片(2)上开有孔。

Claims (1)

1.一种带孔式战舰由船体(1)和螺母(3)组成,叶片(2)由螺母(3)安在船体(1)上,其特征在于:叶片(2)上开有孔。
