Electrical power distribution system based on 1553B bus for advanced aircraft

A novel aeronautical electrical power distribution system based on 1553B bus is proposed in this paper with the analysis of aircraft electrical power distribution system structure. First, several control schemes such as CCS (centralized control system) are researched and the benefit of DCS (distributed control system) configuration is analyzed. Then according to the control flow of aircraft electrical power distribution system, the host-hypotaxis bus topology of mcs-96 distribution system is employed comparing several network topologies on basic cost, communication cost, program cost and reliability etc. Finally the implement of 1553B bus in aircraft electrical power distribution system is presented with the key design consideration on both hardware and software presented, including the isolated 1553B bus interface circuit, address selection circuit, memory management and design of information frames. The communications results and the analysis are given to verify the analysis while the key signals on the bus analyzed in detail.
