An Intelligent Semi-Physical Simulation System For Hybrid Flight Vehicles

An Intelligent semi-physical simulation system of flight control system of the Hybrid Flight Vehicle(HFV) is proposed. It is designed according to the requirement of flight control system test, demonstration of flight control algorithm, as well as simulation of flight under multiple flight conditions. The hardware of the system is consisted of flight control computer, portable test box, and the simulation computer. The system, portable and universal, setting serial port communications, switch communications, optical communications, data acquisition and flight control in one. Using Real-Time eXtension(RTX) and Microsoft Foundation Classes (MFC) as the development environment, the software of system is based on a modular design concept, giving a friendly human machine interface and easily expanding. The simulation platform has been successfully applied to the ground simulation of the flight control system, completing multi-state flight simulation, achieving comprehensive bus information monitoring, data-storage and display in real time. The system gets the condition that may occur during the flight, laying the solid foundation for the flight test.
