Patent

CA 2673975

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 (10) is made using a number of components (38, 44, 50, 56, 62, 64), which are assembled to provide a structure that is sufficiently strong to maintain the spar shape during pre-cure lay up, compaction and curing of the composite material. The multiple components used to form the mandrel can be separated from each other and easily removed from the spar either before or after curing of the composite material. The mandrel components 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 en matériau composite, une matrice à multiples composants étant utilisée pour former le longeron composite. La matrice est fabriquée en utilisant un certain nombre de composants qui sont assemblés pour donner une structure qui est suffisamment forte pour maintenir la forme de longeron pendant l'assemblage de précuisson, le compactage et la cuisson du matériau composite. Les multiples composants utilisés pour former la matrice peuvent être séparés les uns des autres et facilement retirés du longeron avant ou après la cuisson du matériau composite. Les composants de la matrice peuvent alors être réassemblés et réutilisés pour former d'autres longerons composites.
