description | A rotor blade for an aircraft includes a composite portion having fiber-reinforced resin material, the composite portion having an outside surface that forms at least a partial airfoil shape. The weighted portion includes a plurality of weighted material layers and a plurality of fiber-reinforced resin material layers. Weighted material is configured to be compatible with and integrated into composite manufacturing processes used to fabricate the rotor blade. The weighted portion has a higher density than the composite portion and positioned to produce desired mass balance characteristics of the rotor blade.
L'invention concerne une pale de rotor d'un aéronef qui comporte une partie composite ayant un matériau en résine renforcée par des fibres, la partie composite ayant une surface extérieure qui présente au moins une forme aérodynamique partielle. La partie pondérée comporte plusieurs couches de matériaux pondérées et plusieurs couches de matériaux en résine renforcée par des fibres. Le matériau pondéré est conçu pour être compatible et solidaire avec des procédés de fabrication de composites utilisés pour produire la pale de rotor. La partie pondérée présente une densité plus élevée que la partie composite et est adaptée pour produire des caractéristiques d'équilibre de masse de la pale de rotor. |
