| description | Methods and apparatus are provided for making a rotor blade spar from composite material wherein a multi-component mandrel is used to form the composite spar. The mandrel is made using a number of components that are assembled and held in place using a roller assembly. The roller assembly is removed after pre-cure lay up and compaction of the composite material. Once the roller assembly is removed, the remaining mandrel components can be separated from each other and easily removed from the spar. The mandrel components, including the roller assembly, can then be re-assembled and re-used to form additional composite spars.
L'invention concerne des procédés et un appareil permettant de fabriquer un longeron de pale de rotor à partir d'un matériau composite. Un mandrin à plusieurs composants est utilisé pour former le longeron composite. Le mandrin est fabriqué au moyen d'un certain nombre de composants qui sont assemblés et maintenus en place au moyen d'un ensemble rouleau. L'ensemble rouleau est retiré après l'assemblage et le compactage du matériau composite avant le durcissement. Une fois que l'ensemble rouleau est retiré, les composants de mandrin restants peuvent être séparés les uns des autres et facilement retirés du longeron. Les composants de mandrin, dont l'ensemble rouleau, peuvent ensuite être assemblés de nouveau et réutilisés pour former des longerons composites supplémentaires. |
