摘要： A hydrokinetic turbine system, including a plurality of hydrokinetic turbines is installed on a bed of a body of water. Each turbine has a shroud with a forward entrance portion and rear exit portion. The shroud includes a propeller disposed in a middle portion thereof. An inner surface of the shroud includes a plurality of rifling vanes formed therein to induce water entering the forward entrance portion to rotate in a vortex-like fashion. A plurality of pre-spin guard blades disposed adjacent the forward entrance portion also induce rotation of water and serve to provide a barrier preventing objects from passing into the forward entrance portion. A plurality of stabilizers extending from an exterior surface of the shroud that position the forward entrance portion in the direction of current flow.
