Abstract

Es wird ein Rotorelement (10) zur Umströmung durch ein Fluid und für einen Rotor (20) offenbart. Es umfasst ein Rotorblatt (12), das zwei Seitenflächen aufweist, und eine dem Rotorblatt (12) zugeordneten Strömungsleitfläche (14), deren Nachlauf wenigstens teilweise die Anströmung an einer der Seitenflächen des Rotorblattes (12) beeinflusst.
