The development of the distributed simulation technology is greatly dependent on the development of computer technology and information technology.Characterized by information sharing and collaboration,the grid technology provides new thoughts for the simulation application.The features of grid technology and distributed simulation technology are analyzed,and the consistency in design conception between them is discussed.Using the grid technology thoughts for reference, the architecture for complex distributed simulation system is emphasized.The architecture of aviation domain could be divided into simulation research and development environment,run time environment and resource repository.The aviation system simulation integrated environment would provide effective technical methods and comprehensive platform for the design of aviation weapon systems.

Connotation of Synthesis Display System and status quo were proposed; the architecture of Synthesis Display System was introduced based on Flight Simulator Platform, and the key techniques were studied. Data Fusion was implemented by Fuzzy Logic Inference; the problem of coexistence of the 2 dimension displays and 3 dimension displays was solved by Image Fusion; the idea and technique of modularization were used during design and implement of the system. At last, a summary of the developing tendency of Synthesis Display System was given.
