Abstract

1. Ветроэнергетическая установка с пониженным уровнем шума, содержащая неподвижно закрепленные на оси передний и задний обтекатели, расположенный между ними ротор в виде втулки с лопатками основной ветротурбины и кольцевой диффузорный ускоритель, зафиксированный на обтекателях посредством неподвижных стоек и лопаток направляющего аппарата, отличающаяся тем, что за основной ветротурбиной по направлению потока размещена, по крайней мере, одна дополнительная ветротурбина, расположенная внутри кольцевой обечайки, диаметр которой меньше внутреннего диаметра кольцевого диффузорного ускорителя.2. Ветроэнергетическая установка по п.1, отличающаяся тем, что лопатки дополнительной ветротурбины закреплены на втулке ротора основной ветротурбины.3. Ветроэнергетическая установка по п.1, отличающаяся тем, что кольцевой диффузорный ускоритель выполнен в виде трех кольцевых крыльев, расположенных вдоль оси друг за другом и имеющих последовательно увеличивающиеся диаметры.1. Wind power installation with a reduced noise level, comprising front and rear cowls fixedly mounted on the axis, a rotor located between them in the form of a sleeve with blades of the main wind turbine and an annular diffuser accelerator fixed to the cowls by means of fixed racks and vanes of the guide apparatus, characterized in that at least one additional wind turbine located inside the annular shell, the diameter of which is smaller than the main wind turbine in the direction of flow inner diameter of a ring diffuser accelerator. 2. The wind power installation according to claim 1, characterized in that the blades of the additional wind turbine are mounted on the rotor sleeve of the main wind turbine. The wind energy installation according to claim 1, characterized in that the annular diffuser accelerator is made in the form of three annular wings located along the axis one after another and having successively increasing diameters.
