Description

Technical field [0001] The embodiment of the present invention relates to the technical field of aircraft avionics test, in particular to a semi-physical test method and system for aircraft avionics system. Background technique [0002] Aircraft avionics system test refers to the test conducted before the official use of aircraft avionics system to check the performance of aircraft avionics system equipment. The aircraft avionics system is an important part of the aircraft. The avionics system test is used to verify the design index and manufacturing level of the aircraft's avionics equipment. It is an important means for researchers to understand the status of the aircraft's avionics equipment to optimize the design. The avionics system is cross-linked with other aircraft systems, and its testing is a system project that costs a lot of money, is complicated in technology, and involves a wide range. The rapid development of modern computer technology has laid a strong foundation...

Problems solved by technology

[0008] None of the technical solutions at the above three levels realize the dynamic cross-linking of avionics system design indicators with existing real airborne equipment or aircraft simulator data at the initial stage of aircraft avionics system design, and design defects cannot be found as early as possible, resulting in low efficiency. Repeated cost is high
