Abstract
L'invention concerne une hélice multipale à pas variable. Cette hélice comprend au moins une paire de pales opposées, 3al et 3a2, portées par une même lame allongée la, en fibres à haute résistance, qu'un axe 5 traverse par une ouverture médiane 4a, de la lame la; chaque pale comprend une coquille 3a1 fixée à la partie correspondante de la lame 1a, par une masse de matiere synthétique adhésive, 10a1. Le pied de chaque pale 3a1 est muni d'un manchon 11a1, par un bras latéral, 13a1, duquel on peut tordre la lame 1a, pour communiquer un pas approprié à ladite pale. L'invention est applicable en particulier à la réalisation d'un rotor arrière de giravion.
