The invention belongs to the field of the manufacturing industry of surface ships, underwater submarines and other aircrafts, and particularly relates to a propeller, in particular to a pump jet propeller which works by using large-area paddles to generate liquid pressure difference. And a high-speed propeller is not used, so that the rotating friction energy consumption of the propeller and water flow is reduced, and the injury to innocent fishes is avoided. The action area of the wide and large blade paddles for extruding water flow is large, the water flow pushing speed can be reduced, energy consumption is reduced, and ship pushing power is improved. When the blade paddles swing, a large low-pressure water absorption area is formed in front of the ship, forward pulling force is additionally generated on the ship, and meanwhile the forward resistance of the ship is reduced. When the blade paddles swing, water is sprayed behind the ship to generate advancing thrust, meanwhile, a high-water-pressure area is formed behind the ship, the high water pressure in the area can push the tail of the ship, and advancing power of the ship is increased. Therefore, the pump jet propeller has high application value and wide market prospect.

    本发明属于水面船舶及水下潜艇及其它航行器制造业领域,具体涉及的一种推进器,具体地说,是一种用大面积的桨叶产生液体压力差进行工作的一种泵喷推进器。不用高速的螺旋桨,既降低了螺旋桨和水流的旋转摩擦能耗,又避免了对无辜鱼类的伤害。宽大叶桨挤压水流的作用面积大,可以降低推动水流的速度,降低能耗,提升推动船舶的动力。叶桨摆动时,在船舶前方形成很大的低压的吸水区,额外对船舶产生向前的拉力,同时减小船舶前进阻力。叶桨摆动时,在船舶的后方喷水,产生前进推力,同时会在船后方形成高水压区,这个区域的高水压也能推动船舶尾部,增加船舶前进的动力。因而这种泵喷推进器具有很高的应用价值和广阔的市场前景。
