Abstract

The problem in given article consists in definition of power interaction of a lattice of the turbine witha liquid stream. The moment on the driving wheel is equal to change of the moment of quantity of movement of aproceeding liquid. To find the moment and capacity on a driving wheel shaft, it is necessary to define kinematicparameters of the stream which is flowing round a lattice of a wheel. At calculation new the blade systems the returnproblem of the theory of lattices is used. The return problem consists in definition of the form of a profile under theset law of distribution of speed (pressure) on a profile contour, and as in definition of power interaction of a streamand a lattice profile. For durability calculations of water-wheels it is necessary to know the hydrodynamic forcesoperating on the blade of the driving wheel. Analysis and study of the peculiarities of electromagnetic calculationdisk generator in static mode does not allow to evaluate the work make full disk generator. This regard, studies havebeen conducted dynamic mode disk generator. Studies and calculations were carried out by computer simulationusing the program «Ansoft Maxwell».Us essentially new design of micro hydroelectric power station with doublerotorthe hydro generator is offered.
