Abstract
Mit einem Panelverfahren werden Hubschrauberrotoren im Schwebeflug und im Vorwaertsflug berechnet. Der Rueckwirkung der Blattspitzenwirbel auf den Rotor wird mit einem Nachlaufmodell von Beddoes beschrieben. Zur Berechnung der Laermabstrahlung wird die Ffowks Williams/Hawkings Gleichung unter Beruecksichtigung der Monopol und Dipolterme verwendet.
