The invention provides a double-duct shaftless water-jet propeller which comprises a power cabin, a front impeller and a rear impeller, a front flow channel and a rear flow channel which are communicated with each other are arranged in the propeller, the front impeller capable of rotating is arranged in the front flow channel, the rear impeller capable of rotating is arranged in the rear flow channel, and the front flow channel and the rear flow channel are communicated with each other. The power cabin is used for driving the front impeller and the rear impeller to rotate. A front inlet rotating valve is arranged at an inlet of the front flow channel, a rear inlet is arranged at the butt joint position of the rear flow channel and the front flow channel, a rear inlet rotating valve is arranged on the rear inlet, an electric control device is arranged in the power cabin, and the electric control device controls the front inlet rotating valve and the rear inlet rotating valve. According to the shaftless water-jet propeller, the propulsion mode of the shaftless water-jet propeller is changed by changing the opening and closing conversion of the inlet, and the mechanism allows the speed of water flow to be adjusted, so that the thrust is changed.
本发明提供了一种双涵道无轴喷水推进器,包括动力舱、前置叶轮和后置叶轮,所述推进器内设有相互连通的前流道与后流道,所述前流道内设设有可以转动的前置叶轮,所述后流道内设设有可以转动的后置叶轮,所述动力舱用于分别驱动前置叶轮与后置叶轮转动;所述前流道的进口设有前置进口转动阀门,所述后流道与前流道对接处为后置进口,后置进口上设有后置进口转动阀门,所述动力舱内设有电控装置,所述电控装置控制前置进口转动阀门和后置进口转动阀门。本发明通过改变对进口的开闭转换,实现了无轴喷水推进器推进模式的变化,这一机制允许调整水流的速度,从而实现推力的变化。
