| 摘要 |
The present invention pertains to a wind power installation (1) for generating energy, especially electric power, by means of the movement of ambient air, which installation comprises a flow channel (3), in which the ambient air is formed into a stream which flows through the channel, wherein the flow channel (3) comprises an outer jacket (5) forming its boundary, with:
a first section (A) with a tapering, funnel-like cross section, into which a first portion of ambient air enters and is accelerated;a second section (B) of essentially constant cross section, in which a rotor (20) is present, which can be set into rotation by the through-flowing ambient air, wherein the second section (B) comprises a tubular extension (67);a third section (C), through which the tubular extension (67) of the second section (B) extends and which comprises a tapering, tubular inlet funnel (44), which surrounds the tubular extension (67) and serves to allow a second portion of ambient air to enter the flow channel (3);a fourth section (D), in which the tubular extension of the second section (B) terminates, and which comprises a plane of the least cross section (the “0” plane) of the flow channel through which the first and second portions of ambient air flow;a fifth, expanding, section (E); anda sixth section (F), which follows the fifth section (E), and in which at least one air acceleration device (11) is arranged. |

1. A wind power installation for generating electric power by means of movement of ambient air, the installation including a flow channel having a boundary formed by an outer jacket in which the ambient air is formed into a stream flowing through the channel, the channel comprising seriatim:
a first section with a tapered funnel-like cross-section of decreasing cross-section into which a first portion of ambient air enters and is accelerated; a second section of substantially constant cross-section formed by a tube and having a rotor therein which is rotatable by the through-flow of ambient air, the rotor coupled to and driving a generator; a third section into and through which an extension of the tube of the second section extends such tube extension having the substantially constant cross-section, the third section including a tapered inlet funnel of decreasing cross-section surrounding the tube extension and serving to allow a second portion of ambient air to enter the flow channel around the tube extension; a fourth tapered section in which the tube extension terminates, said fourth section ending in a cross-sectional plane of least cross-section through which the first and second portions of ambient air flow; an expanding fifth section; and a sixth section in which at least one air acceleration device is arranged. |
