The invention discloses a rotational flow shaftless pump ship propelling system. The system comprises a front fluid director, a propeller and a rear fluid director. The front fluid director, the propeller and the rear fluid director are all of an annular water flow channel type structure. By arranging the fluid directors with a plurality of independent annular pressure-equalizing water flow channels and the propeller with a plurality of independent spiral pressure-applying water flow channels, the stability of water flow is improved, violent channeling is avoided, the contact area between thewater flow and the propeller and the water flow flowing stroke are increased, edge streaming is avoided, and the conversion efficiency is greatly improved. And meanwhile, the effects of reducing vibration and noise are achieved, and the stability and concealment of the ship are improved.

    本发明公开了一种旋流无轴泵船舶推进系统,该系统包括前导流器、推进器以及后导流器。所述前导流器、推进器、后导流器均为环形水流通道式结构。通过设有具有多个独立的环形均压水流通道的导流器和具有多个相互独立的螺旋施压水流通道的推进器,提高了水流的稳定性,避免发生激烈窜流,以及增大了水流与推进器的接触面积和水流流经行程,避免缘部绕流,大大提高了转换效率。同时还具有减少振动和降低了噪音的效果,提高了船舶的稳定性和隐蔽性。
