Abstract

Rotorblatt (1) mit mindestens einem an dem Rotorblatt angeordneten piezoelektrischen Dämpfungselement (2) und mit mindestens einer Dämpfungssteuerung, die zum Ansteuern des mindestens einen piezoelektrischen Dämpfungselements mittels elektrischer Energie eingerichtet ist, wobei das mindestens eine piezoelektrische Dämpfungselement zum Aufbringen einer Kraft mittels der elektrischen Energie auf das Rotorblatt ausgebildet ist und mit dem Rotorblatt derart zusammenwirkt, dass eine Verformung des Rotorblattes durch die aufgebrachte Kraft des piezoelektrischen Dämpfungselements gedämpft wird.
