Aiming at the problem of in-flight semi-physical simulation experiment structure of aeronautic and flight system for aircraft in-flight, this paper proposes a system architecture scheme of aircraft avionics simulation system based on RTX real-time environment and an engineering feasible method. The simulation system based on the scheme and method makes full use of computer software and hardware platform and virtual technology to simulate the characteristics of the avionics system of the aircraft, thus providing a good simulation and verification method and technology for the semi-physical simulation of the avionics system of the aircraft stand by. The system is successfully applied in semi-physical simulation experiments of a helicopter avionics system, which provides the experimental means and verification basis for the stereotype verification of the avionics system of the helicopter.
