Flight Test Validation System Construction And System Design

With the rapid development of our economy, civil air transport industry has also become the world’s second largest air transport market, but the domestic civil aviation market is dominated by Boeing and Airbus Company. The research and development of domestic large civil aircraft not only can reflect the national attention to the high technology industry, but also can drive the development of national economy. In the development process of domestic large civil aircraft, the process of flight test verification is extremely important. Among them, the airborne test system is the core of the flight test verification. So, whether to establish correct airborne test system is directly related to the success of the flight test. This paper is aimed at the background of the airborne test system in domestic large civil aircraft test verification.The work of this paper is the design of the system structure of ground test verification platform in domestic large civil aircraft test verification. The main function of the flight test verification platform is provide test signal for airborne testing system on the ground and make functional verification to ensure flight safety before the flight of the aircraft. This paper firstly introduces the development process and the verification requirements of airborne testing system, analysis of the signal types and verify the number of channels and other indicators in flight test verification platform; proves the rationality of the structure “Signal generation + conditioning output” of the signal generation part in flight test verification platform; design and test the hardware components in signal generation part. To achieve communication transmission of flight test verification platform from internal bus and external bus. To achieve the integrated design of the whole system with "the cabinet integration". Finally design test, which test flight test verification platform validation overall performance, verified flight test platform completely satisfy the requirement of the airborne testing system for functional verification.
