Research on key technologies of air-to-ground integrated monitoring network system for civil aircraft flight test

According to civil aircraft airworthiness certification flight test requirements and test characteristic,key technologies of airborne and ground-based systems were analyzed in terms of system architecture optimization and balanced system performance with ARJ21 airworthiness certification test engineering as the study background.The problems of novel web-based multi-channel data acquisition on airborne and ground-based monitoring were solved.An air-to-ground intergrated monitoring network system,suitable for civil aircraft airworthiness certification test,was proposed in this paper.The flight test results indicated that the system was able to meet the demands of air-to-ground integrated monitoring for civil aircraft airworthiness certification flight test,which provided a reference for the further study on large aircraft flight test and intergrated monitoring approaches.
