Beschreibung
Zusammenfassung:	Disclosed is a blade (30) for an impeller (20) of an independently driven turbomachine, in particular for a fan; the blade, which is operatively connected to a hub (40) of the impeller (20), can be driven at variable speeds and is elastically deformable in accordance with the speed of the impeller (20), the blade (30) having a first blade geometry in a first speed range and a second blade geometry in a second speed range, the blade (30) taking a predetermined fluidically relevant shape in accordance with the impeller speed.
