This article discusses the design and realization of a real-time simulation system, which is based on broad memory network. It implements real-time communication between stations or among stations.The software is programmed by Visual C++ 6.0.The characterastics of the plane dynamics and kinematics,the flight sensors are simulated by computer simultation and realtime animation techniques.The system has good realtime characterastics and high reliability. The actual application shows that the system has good performances and can meet the requirements of hard-in-the-loop realtime simulation experimentation used for testing the flight control system.
