Abstract: In order to meet the goal of engine weight reduction, the development of by-pass duct casing made of resin matrix composite was carried out. According to the operation requirements, the structural design process is described from the aspects of connection form, material selection, ply principle and structural design. The verification of design scheme is carried out through the simulation analysis. Based on the development scheme, the prototyping and manufacturing process is introduced from the aspects of mould design, shell forming, machining forming and non-destructive inspection. According to the ground test, it is concluded that the by-pass duct casing under development meets the requirements of engine operation.

Key words: resin matrix composite, aero-engine, by-pass duct casing, structural design, prototyping and manufacturing
