Aiming at the civil aircraft with double passive side bar, the visual simulation research is carried out to design a complete set of flight visual simulation system with independent intellectual property right, which is used in the research and design of civil aircraft flight control system. The system combines the system simulation technology and flight visualization technology, fully taking into account the characteristics of passive double-pole commercial aircraft design simulation platform. Self-prepared core dynamics procedures and control laws have good originality, developability and scalability. Make full use of the open source flight simulation software FlightGear provides visualization capabilities and data interface for real-time status display and real-time hardware input. The simulation results show that the simulation system can truly and effectively reflect and record the real-time flight status of the civilian aircraft with passive side bar, and the simulation fitting degree is high. The entire simulation system structure is clear, scalable, easy to use. It provides an excellent visual open simulation platform for the research and design of the related aircraft control system and can further serve the research design of the whole system flight control law.
