Aiming at the problems of real-time and synchronization of distributed simulation system, this paper analyzes the actual demand of each subsystem of flight simulator, and follows the principle of economic, high efficiency and modular development of engineering design. Through the reasonable choice of hardware and elaborate design of software, The real-time synchronous network architecture based on reflective memory network and Ethernet perfectly solves the defects of high delay and poor stability of the traditional design scheme, and improves the practicability and universality of the system. The scheme is actually applied to a certain type of aircraft simulator system and shows the advantages of stability and high efficiency in the joint training test and air force contract training. Therefore, the scheme can be used as a standardized and practical method for distributed simulation in the field of flight simulation Solution.
