MULTIPLE MATERIAL COMBINATIONS FOR PRINTED REINFORCEMENT STRUCTURES OF ROTOR BLADES

Rotor blade panels, along with methods of their formation, are provided. The rotor blade panel may include one or more fiber-reinforced outer skins having an inner surface; and, a plurality of reinforcement structures on the inner surface of the one or more fiber-reinforced outer skins, where the re...

Beschreibung
Zusammenfassung:	Rotor blade panels, along with methods of their formation, are provided. The rotor blade panel may include one or more fiber-reinforced outer skins having an inner surface; and, a plurality of reinforcement structures on the inner surface of the one or more fiber-reinforced outer skins, where the reinforcement structure bonds to the one or more fiber-reinforced outer skins as the reinforcement structure is being deposited. The reinforcement structure includes, at least, a first composition and a second composition, with the first composition being different than the second composition. L'invention concerne des panneaux de pale de rotor, ainsi que des procédés de formation de ceux-ci. Le panneau de pale de rotor peut comprendre une ou plusieurs peaux externes renforcées par des fibres ayant une surface interne; et, une pluralité de structures de renforcement sur la surface interne de l'une ou des peaux externes renforcées par des fibres, la structure de renforcement se liant à la ou aux peaux externes renforcées par des fibres lorsqu'elle est en cours de dépôt. La structure de renforcement comprend, au moins, une première composition et une seconde composition, la première composition étant différente de la seconde composition.
