Abstract: 본발명은어뢰나잠수정과같은수중운동체를수중에서전진시키는펌프제트추진장치에관한것으로서, 종래수중운동체의추진장치는주로프로펠러가사용되어편향회전에따른불필요한토오크가발생되고, 과부하상태에의하여방사소음이증가되어피탐가능성이증가되는문제점이있었다. 본발명의수중운동체추진장치는회전날개(10) 및고정날개(20)와상기회전날개(10)와고정날개(20)를둘러싸는덕트(30)로구성되어, 수중에서의추진효율을향상시키고방사소음을감소시키며토오크평형에의하여수중운동체의균형을유지시킬수 있다.

Abstract: PURPOSE: A jet pump type propulsion is provided to increase propelling efficiency under the water and enable an underwater mover to balance by little radial noise and a torque balance. CONSTITUTION: A duct(30) surrounds each rotating piece of a rotating wing(10), having a fine interval between the end of the piece and the inside of the duct. The end of each fixing piece in a fixing wing(20) is fixed to the rear end of the duct. Thus, inlet flux from the rotating wing is adjusted by the inverse flux of an underwater mover to suppress cavitation. Therefore, radial noise from the rotating wing is remarkably reduced.
