Research on Building Aircraft Level Test Platform Technology Through Interconnected Systems

Xu, Na / Wu, Chen / Wang, Huanyu / Zheng, Kai

In order to conduct sufficient ground tests on aircraft level functions, it is necessary to conduct real physical cross-linking tests on important aircraft systems such as power, hydraulic, avionics, main flight control, high lift and landing gear, and conduct simulation tests on various stages, scenarios and operations during the flight process.

This paper studies the interconnection system of the test bench, utilizing the clock synchronization system, gigabit fiber optic Ethernet, signal acquisition, signal reconstruction system and reflective memory network to achieve real-time data exchange, the dedicated power supply and distribution test cable is used to interconnect the power supply network. Based on the above, separate and interconnected experiments will be integrated to construct an aircraft level ground test environment.

The aircraft level ground test environment was constructed using this method during the first flight and type certification ground tests of the certain type aircraft. The first flight profile and typical profile tests of the certain type aircraft were conducted, and the aircraft fault scenario and emergency scenario tests were completed, which supported the first flight and type certification of the certain type aircraft. By using this method, discrete experiments can be interconnected to construct an aircraft level ground test environment.
