Windmill powerplant

A wind power unit in the form of a support-installed power-generator having at least one turbine mechanically connected to at least one generator and with a front shell defining at least one input channel to the turbine, the front shell having an interior and exterior surface and a trailing edge, the unit including a central shell having an external surface and cooperating with the front shell to form a turbine output channel between the front shell and the central shell, the unit having an annular external shell surrounding at least a portion of the central shell and cooperating with the central shell to form a diffuser output channel, the unit comprising:

• an additional annular shell having an interior and exterior surface and having a trailing edge, the annular shell being located intermediate the external shell and both of the central and front shells, the interior surface of the additional annular shell cooperating with external surfaces of the front and central shells to form a first annular intermediate channel that is connected in an intermediate part with the turbine output channel, the external surface of the additional annular shell cooperating with the internal surface of the external shell to form a second annular intermediate channel connected with the first intermediate channel and with the diffuser output channel;
• a movable output part on the trailing edge of the additional annular shell, wherein the output part is movable to change a cross-section of the first and second intermediate channels, which increases the kinetic energy of the air flow through the first and second intermediate channels;
• and
• a movable output part on the trailing edge of the front shell, wherein the output part is movable to change a cross-section of the turbine output and first intermediate channels, which increases the kinetic energy of the air flow through the first and second intermediate channels.

A method for transforming energy of a first gas flow using a wind power unit in the form of a support-installed power-generator having at least one turbine mechanically connected to at least one generator, the method comprising:

• accelerating the energy of a first gas flow in front of the turbine by using a component of the first gas flow, while simultaneously creating rarefaction behind the turbine by creating rarefaction across an output section of a profiled duct communicated to a minimum-section zone, where the first gas flow is affected by the component of the first gas flow streaming directly past a deflector;
• streaming the first gas flow past the outer envelope to produce rarefaction in the output section due to ejection;
• and
• creating multi-stage acceleration of the first gas flow, which increases the use of the energy of the first gas flow.

A wind power unit in the form of a support-installed power-generator comprising a support, at least one turbine and mechanically connected to at least one generator, a central shell having an external surface, a front shell having an interior and exterior surface and a trailing edge and defining at least one input channel of the turbine with the front shell cooperating with the central shell to form a turbine output channel between the front shell and the central shell, and an annular external shell surrounding at least a portion of the central shell and cooperating with the central shell to form a diffuser output channel, the unit comprising:

• an additional annular shell having a trailing edge cooperating with the external surfaces of the front and central shells to form a narrowing-extending first intermediate channel that is connected in an intermediate part with the turbine output channel, the additional annular shell cooperating with the internal surface of the external shell to form a second intermediate channel that is connected with the first intermediate channel and with the diffuser output channel;
• and
• a movable output part on the trailing edge of the additional annular shell, wherein the output part is movable to change a cross-section of the first and second intermediate channels, which increases the kinetic energy of the air flow through the first and second intermediate channels.
