FIELD: engines and pumps.
SUBSTANCE: invention relates to water power engineering and can be used in hydroelectric power stations at river-, sea- and ocean-sites with notable streams and waves. In compliance with this method, working blades are arranged in assembly consisting of confuser and diffuser and drive by accelerated water flow forced through aforesaid assembly anchored to bottom, deep in water. Ar minimum drag, maximum water stream speed in the assembly narrow section is reached. Additional acceleration of water flow occurs due to outer water flows flowing all around aforesaid assembly. The latter represents Laval nozzle with streamline outer surface. Confuser and diffuser feature slope directed towards bottom and upper part extending forward and rearward. Nozzle position is corrected by varying anchoring rope tension, filling sea cocks with air or water, and thanks to sloped sections of confuser and diffuser.
EFFECT: higher efficiency, expanded performances.
