| 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); and a sixth section (F), which follows the fifth section (E), and in which at least one air acceleration device (11) is arranged. |
