Are developed, are tested and the two-element blades for curls windmill, ensuring their self-start and reaching of high significances of operating ratio of a wind power are recommended in production. The expediency of application of power amplifiers of a curl is theoretically proved, that has the special significance for regions with rather low velocities of a wind. The experiments on a research of a field of velocities in a near neighborhood of the transparent cylinder are executed. The inexpedience of a frequency control of rotation of a curl is shown, for it can reduce in a diminution of development of energy. The simple method of scoping of development of the electric power by the wind turbine on known midyears of a velocity of a wind in the location windturbine is offered. The aerodynamic scheme and construction of the vertically - axial wind turbine by a potency of 3 kw (for wa nt of rated speeds of a wind of 7 m Product Description popup.authors popup.nrat_date 2020-04-03 Close
