Design and Realization of Real-Time Flight Testing System Based on VeriStand

In order to solve the problem of real-time flight simulation test of the modified vehicle, a design and realization scheme of real-time flight test system was proposed in this paper. The working process and technical features of flight control system and safety control system that would be tested was analyzed firstly and the function of the real-time test system was listed. Based on the function demand, the hardware structure was suggested that the system should be composed by PC and PXI real- time computer, at the same time, the hardware resource was advised. The configuration and management of real-time test project, the software of real-time model, the diver software of the dummy series interface equipment in the system was respectively developed by VeriStand, MathWorks Simulink?, LabVIEW, the development process of the real-time model software and the dummy series interface equipment software was discussed detailedly. The real-time test results was analyzed finally.
