Title
(DE) ROTOR MIT INTEGRALER BESCHAUFELUNG
(EN) ROTOR WITH INTEGRATED BLADING
(FR) ROTOR A AUBES INTEGREES
Abstract
(DE) Die Erfindung betrifft einen Rotor mit integraler Beschaufelung, insbesondere für ein Triebwerk, an dem umfänglich und sich im wesentlichen radial erstreckend Rotorschaufeln angeordnet sind, wobei die Rotorschaufel zur Verringerung von Schwingungen einen metallischen Schaufelfuss, einen metallischen Schaufelblattabschnitt, der wenigstens einen Teil der Schaufelvorderkante und des daran angrenzenden Bereichs der Schaufelfläche bildet, und ein Schaufelblatt aus faserverstärktem Kunststoff aufweisen.
(EN) The invention relates to a rotor with integrated blading, especially for a propulsion unit on which rotor blades are arranged circumferentially and extend in an essentially radial manner. In order to reduce vibrations, the rotor blades comprise a metallic blade footing, a metallic blade pan section, said section at least constructing a part of the blade fore-edge and the area of the blade surface which is adjacent to said blade fore-edge, and a blade pan made of fiber reinforced plastic.
(FR) L'invention concerne un rotor à aubes intégrées destiné notamment à un propulseur. Les aubes ont une disposition sensiblement radiale et sont réparties sur toute la circonférence du rotor. Afin de réduire les vibrations, les aubes présentent une emplanture métallique, une section pale métallique qui constitue au moins une partie du bord d'attaque de l'aube et de la zone adjacente de la surface d'aube, et une pale en matière plastique renforcée par des fibres.
