This paper introduces the technical feature of a former developed MDO (Multidisciplinary Design Optimization) architecture for spacecraft design, which is called Spacecraft Distributed Design Environment (SDIDE). SDIDE is an interactive spacecraft design system based on distributed network computing environment. It applies MDO in the whole lifecycle of spacecraft design, and makes nearly all kinds of system-level and discipline-level analysis tools work collaboratively. SDIDE uses a flexible bus scheme based on Common Object Request Broker Architecture (CORBA) to improve the integration and efficiency.
The paper takes the structural optimization of the Tsinghua University "NS-1" small satellite as an example to illustrate the usage of the software system of SDIDE in assisting the overall design of satellite. The result of calculation shows that the software system can effectively decrease the cost of developing a satellite system and improve the overall performance of the satellite, accordingly proving the practicality and feasibility of the SDIDE architecture into the design process of a spacecraft.
