Wind-speed accelerating wind turbine

A wind-speed accelerating wind turbine comprising:

• a wind turbine;
• an inner nacelle;
• and an outer nacelle provided outside the inner nacelle, wherein the wind turbine is installed in the inner nacelle, the inner nacelle includes:
• a front nacelle member having a cross-section area formed so as to linearly or curvilinearly contract from a wind inlet to an installed position of the wind turbine;
• and a rear nacelle member having the contracted cross-section area formed so as to linearly or curvilinearly expand or maintain the same cross-section area from the installed position of the wind turbine to a wind outlet, and a wind dispersion part is formed at the wind outlet of the rear nacelle member.

A wind-speed accelerating wind turbine comprising:

• a wind turbine;
• an inner nacelle;
• and an outer nacelle provided outside the inner nacelle, wherein the wind turbine is installed in the inner nacelle, the inner nacelle includes:
• a front nacelle member having a cross-section area formed so as to linearly or curvilinearly contract from a wind inlet to an installed position of the wind turbine;
• and a rear nacelle member having the contracted cross-section area formed so as to linearly or curvilinearly expand or maintain the same cross-section area from the installed position of the wind turbine to a wind outlet, a wind dispersion part is built at the wind outlet of the rear nacelle member, and the outer nacelle has a wind inlet at a position corresponding to a wind outlet of the inner nacelle or in a vicinity thereof, and is formed so as to linearly or curvilinearly expand or maintain the same cross-section area from the wind inlet to the wind outlet.

A wind-speed accelerating wind turbine comprising:

• an inner nacelle in which a wind turbine is installed;
• and an outer nacelle provided outside the inner nacelle, wherein the inner nacelle integrally includes a front inner nacelle member having a wind inlet having a flat transverse cross-section having a width longer than a height and includes a rear inner nacelle member having a wind outlet having a flat transverse cross-section having a width longer than a height, the front inner nacelle member has a transverse cross-section area formed so as to contract from the wind inlet to a connecting part with the rear inner nacelle member, the rear inner nacelle member is formed so as to expand or maintain the same transverse cross-section area from the contracted connecting part of the front inner nacelle member to the wind outlet and has a wind dispersion part or a wind dispersion shape at a the wind outlet, the wind turbine is installed in a vicinity of the connecting part of the front inner nacelle member and the rear inner nacelle member and is configured to have a wind dispersion part in a gap that is not the wind turbine at the connecting part of the front inner nacelle member and the rear inner nacelle member, the outer nacelle integrally includes a front outer nacelle member having a wind inlet having a flat transverse cross-section having a width longer than a height and includes a rear outer nacelle member having a wind outlet having a flat transverse cross-section having a width longer than a height, the front outer nacelle member has a transverse cross-section area formed so as to contract from the wind inlet to a connecting part with the rear outer nacelle member, the rear outer nacelle member is formed so as to expand from the contracted connecting part of the front outer nacelle member to the wind outlet and has a wind dispersion part or a wind dispersion shape at the wind outlet, the wind inlet of the front outer nacelle member is disposed between the connecting part of the front inner nacelle member and the rear inner nacelle member and the wind outlet of the rear inner nacelle member, and the wind outlet of the rear inner nacelle member is disposed at or in a vicinity of the connecting part of the front outer nacelle member and the rear outer nacelle member.

A wind-speed accelerating wind turbine comprising:

• a wind turbine;
• and a nacelle, wherein the wind turbine is installed in the nacelle, and the nacelle includes:
• a front nacelle member having a cross-section area formed so as to have a circular (including elliptical and polygonal) wind inlet, linearly or curvilinearly contract, and gradually form a dispersion shape from the wind inlet to an installed position of the wind turbine;
• and a rear nacelle member having a cross-section area linearly or curvilinearly expanding or maintaining the same cross-section area while maintaining the wind dispersion shape from the installed position of the wind turbine to a wind outlet.
