According to the task requirements of a semi-physical simulation test of a test aircraft, the design of distributed simulation framework is completed. The nodes are divided into three types: server, client and monitor. The scheme of the system and the subsequent extension methods are given. The steps of debugging of the simulation system are introduced in detail, which are divided into three stages: interface matching test, open-loop following and closed-loop simulation. Finally, the comparison between digital simulation and semi-physical simulation is given, Analysis shows that the simulation system meets the design requirements and has high flexibility and scalability.
