Abstract
L'invention se rapporte à l'aéronautique. Elle a pour objet un agencement de montage souple pour rotor d'hélicoptère. Deux coques de pales 3, 4 sont portées par une lame traversante 2 flexible, reliée au moyeu par des plots lamifiés 20 élastiques. Les pieds de pales prennent appui par des articulations à rotule 26a, 27 de centre A. Application à la réalisation de rotors présentant une longue durée de vie et un démontage facile.
