Research On Flight Navigation Display Model Of Distributed Maintenance System

The navigation display is part of the aircraft electronic instrument display system and is responsible for providing pilots with information such as aircraft radio navigation,integrated navigation,and flight plan.The simulation research on navigation display is not only useful on the flight training device,but also plays an important role in maintaining the training device.It is an interface for the maintenance trainer to interact with the maintenance trainer.It can help the trainer to understand the normal and fault phenomena of the navigation display when the aircraft is in the air,so that the trainer has a more complete understanding of the maintenance object.To add flight simulation to the existing distributed virtual maintenance system,the realization of flight navigation display function is an important part of it.It not only needs to meet the interactive requirements of the existing distributed system and normal navigation information display,but also should include internal information display principles and fault information processing,Therefore,it is of great significance to establish a suitable flight navigation display model and simulate it.The following is the main content of this thesis:Firstly,the structure and FTOP flight simulation tools of the existing distributed virtual maintenance system are introduced.The A320 navigation display principle,function and structure are studied.On this basis,the functions and performance requirements of the flight navigation display model are summarized.Secondly,it is proposed to use the multi-agent simulation navigation display information transmission process to establish the overall structure of the multi-agent navigation display model,and use the Agent modeling method to establish each Agent sub-model in detail.Thirdly,the navigation display information in the display management agent is converted into a graphical display of the navigation display(ND),including dynamic compass display,flight plan display,radio navigation display,etc.Finally,a flight navigation display model is built on the basis of the distributed maintenance system,and flight experiments are used as examples to verify the feasibility of the model.
