Abstract

Rotor d'hélicoptère non articulé dont chaque pale est solidaire d'un longeron résistant à la flexion monté tournant sur un moyeu essentiellement rigide par l'intermédiaire de paliers d'angles de pale, des éléments de liaison résistants à la traction étant prévus entre lesdits longerons pour compenser les forces centrifuges. Le moyeu 8 comporte deux plaques de support 4, 6 faites d'un matériau composite fibreux, avec direction radiale des fibres, qui sont maintenues écartées par des renforts de cisaillement 46, 58, 60 et soutiennent entre elles les paliers d'angle de pale 10, 12. Avantages de construction légère et de fiabilité en service.
