Abstract�� Collaborative optimization (CO) method applied into overall design optimization for common aero vehicle and coupled relationship between disciplines were investigated. Process and characters of CO were analyzed. Aimed at common aero vehicle optimization design, research how using CO to built optimization model. Research result shows CO compared with multi-discipline feasible(MDF) has more converge speed, and the reason is system level optimization of CO method is constrained by three subsystem level optimization, constringency of design space speed up, thus realize rapidly iterate converge.
Keywords�� common aero vehicle   multidisciplinary design optimization   collaborative optimization
