Enabling distributed hardware-in-loop simulation for aircraft utilities management system

The utility systems of an aircraft are classed as what related to the control of the basic aircraft electro-mechanical systems. Traditional utility subsystems have developed their own set of mechanical and analog controls as part of their systems, which cause the insufficient use of hardware, congested cockpit and pilots' over-workload. The distributed utility simulation platform supplies common simulation environment for integration design and evaluation of the aircraft utility systems. The simulation platform for integrating hardware and software is based on multi-processors connected to dual redundant data bus. Design engineers can fulfill the study of integrating multiplex utility subsystems and carry out synthesis management and efficient organization of the utility systems. On the platform, the subsystems not only can implement their dedicated functions, but also have the ability of redundancy, fault-tolerance and reconfiguration. The platform supports for both digital and hardware-in-the-loop simulation and offers right-hand simulation and demonstrating tools for the integration design of the aircraft electro-mechanical systems.
