Abstract

This paper introduces an airborne data bus design solution applied to a military-trade multi-role helicopter, which adopts the MIL-STD-1553B data bus standard as the primary standard and supplements it with the ARINC429/RS422 and other data bus standards. The 1553B data bus adopts a dual-bus dual-redundancy architecture to interconnect all the avionics equipment of the helicopter into a zone network. The integrated mission processing system serves as the bus controller for both data buses, enabling data interconnection and intercommunication among all the equipment in the helicopter avionics system. The flight bus and the tactical bus operate independently and realize mutual data backup through the integrated mission processing system, thus featuring high scalability. The specifications and examples of the ICD are provided, which fully verify the reliability and flexibility of the solution. Finally, the paper discusses the prospects of the future development of data buses in the aviation field.
