1. A wind-speed accelerating wind turbine, comprising:
a wind turbine; and
a nacelle, wherein
the wind turbine is installed in the nacelle,
the 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 that disperses wind outside the nacelle is formed at a rim of the wind outlet of the rear nacelle member,
the wind dispersion part includes a plurality of isosceles triangles extending radially outwardly from the rim of the wind outlet and equally spaced from each other to form a star-shape.
