PROCEDE ET DISPOSITIF DE FABRICATION D'UNE CARENE DE ROTOR D'HELICOPTERE, ET CARENE OBTENUE |
摘要 |
The procedure for making a helicopter tail structure (43) with a rotor aperture lined by a ring (63) with two end collars or flanges (66, 70) uses two curved side panels (45) made from a composition material with an organic matrix and reinforcing elements, fixed together by solidifying the matrix. The reinforcing elements are pre-impregnated with resin to form side panel pre-forms that are moulded under pressure. The panel preforms are made from thermoplastic resin-impregnated fibres or fabric and are co-hardened to form a shell to receive the rotor ring. |
