Abstract  In order to meet the requirements of rapid research and development (R & D) on complex components of control system in aero-engine, a rapid R & D iterative method which combines the digital model driving and selective laser melting (SLM) additive manufacturing technology is investigated. Through the establishment of the efficient forward R & D mode based on the enabled additive manufacturing, the integrated iterative process and technical path with “design-simulation-manufacturing-verification-certification” chain was broke through and the optimization of function and performance for system level products was achieved. The engineering application practice indicates that this technology promotes the development of aero-engine control system towards the direction of lightweight, integration, high performance and high reliability, and it drives the innovative R & D and application of complex key parts/components, which can not only shorten the R & D cycle, but also reduce the R & D cost, and greatly improve the system R & D efficiency.
