A new distributed avionics system based on the CANbus and homogeneous nodes

In this paper a new avionic system based on the CANbus is introduced. Fieldbuses offer less weight, standardised technology and simpler system architecture. This appears in contrast with conventional avionic systems. The paper describes main approaches and results of a European research project. The research proposes a completely distributed control, using smart components connected with a CANbus. The research focuses on the fuel management system of helicopters and aeroplanes. The paper describes the monitoring and control problem to be solved, the distributed control architecture and software, the smart components, and development steps till verification on experimental rigs.
