Abstract

Es wird eine Windkraftanlage mit einem Strömungskanal (1) zwischen zwei Kanalwänden (2), von denen zumindest eine eine Außenwand eines Bauwerks (3) bildet, mit wenigstens einer innerhalb des Strömungskanals (1) gelagerten Windturbine (8), deren Rotorachse quer zur Anströmrichtung (7) verläuft, und mit einer den Turbinenrotor (9) im Bereich seiner entgegen der Anströmrichtung (7) drehenden Umfangsseite abschirmenden Leiteinrichtung (13) beschrieben. Um vorteilhafte Strömungsbedingungen zu ermöglichen, wird vorgeschlagen, dass in Anströmrichtung (7) vor und hinter dem Turbinenrotor (9) je eine Leiteinrichtung (13) vorgesehen ist, die zwei einander bezüglich einer in Anströmrichtung (7) durch die Rotorachse verlaufenden Ebene gegenüberliegende, sich über die axiale Rotorlänge erstreckende Leitwände (13) umfasst, die an ihrer von der Windturbine (8) abgekehrten Stirnseite um zur Rotorachse parallele Achsen (15) zwischen einer den Strömungsweg in ihrem Bereich freigebenden Ausgangsstellung und einer diesen Strömungsweg sperrenden Endstellung schwenkverstellbar gelagert sind.
