The embodiment of the invention discloses a semi-physical test method and system for an aircraft avionics system. The system comprises: a test management subsystem for managing test projects, models and data through preset test management; a real-time simulation subsystem performing real-time simulation calculation on n aircraft avionics system and states of the subsystems of an aircraft; and a signal acquisition and output subsystem which is used for data interaction between a simulation system and real airborne equipment, wherein the airborne equipment is real airborne equipment, simulationexcitation equipment is avionics equipment operation environment simulation equipment, and the real-time simulation subsystem comprises an aerodynamic model, a kinetic model, an undercarriage model, amass characteristic model, a motion equation, an atmospheric data model, a GPS model and an inertial navigation model. According to the embodiment of the invention, through closed-loop crosslinking of testing environments of hardware system excitation, the real-time simulation system and the real airborne equipment, various effective ways are provided for the aircraft avionics system testing, andthe invention is close to an external field test.

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...
