Title:     
 
Drei Flatterkriterien für Windturbinenblätter.
 
Abstract:     
 
Die 2. Schlagfrequenz fx2 spielt für Windturbinenblätter eine dominierende Rolle, weil die auf das Blatt einwirkenden Luftkräfte andere Schwingungsformen verhindern. Diese Kräfte nämlich dämpfen die Ausschläge der Blattspitze. In Blattmitte können sie zu Erregerkräften werden und Flatterschwingungen auslösen, wenn eines der drei formulierten Kriterien erfüllt ist.
