Helicopter avionics simulator is one of the essential instruments for the test of a helicopter flightcontrol system. Nowadays there is not such instrument that can be used in the test of a helicopterflight control system at home. To carry out the research on avionics simulator is pressing and is alsodifficult.At the beginning, this paper describes the background of the avionics simulator development forhelicopter, the current situation on the research of avionics simulator at home and aboard, and thecontents and aims of the research.Then it makes an overall introduction of the principle anddeveloping scheme, and a detailed discussion about the hardware component and the softwareconsruction. This paper also introduces the data bus standard of1553B and ARINC429, andapproaches the interface card design of ARINC429. This paper uses wide coverage to discuss theARINC429interface card and software design, and gives emphasis to analyzing the ARINC429businterface card hardware and software design, as well as the system software module, like sendingmodule, receiver module, the self-test function module, network function module and fault diagnosisfunction modules. Compared to other civil avionics simulators, the system adds fault processingmodule, which can control the flight control computer sending the detailed fault data to avionicssimulator according to the fault status, so as to facilitate the subsequent analysis and troubleshooting.Therefore, this system greatly improves the speed of development of the flight control system, andshortens the development cycle.At last, joint test of software and hardware has been done. Experimental results show that the testsystem designed has superior performance and achieves the prospective goals. In addition, it meetsthe technical indicators as well as the functional requirements. With friendly interface, the test systemis easy to use and has high practical value.
