Research And Manufacture Of Helicopter Electronics Flight Display

With the development of electronic technology and information technology,the aviation instrument has developed from simple-functional electromechanical indicator to highly-integrated electronic flight display system.Because the integrated electronic flight display system has the incomparable advantages of the traditional flight instruments in performance,cost,and ergonomics,the integrated electronic flight display system which integrates computer technology,liquid crystal display technology,high speed data bus technology and digital control technology has become the mainstream of modern aviation cockpit display instrument.This project is based on a civil helicopter project,to develop a new electronic flight displays which is a part of a new type of helicopter cockpit display control system.The main function of the electronic flight display contains in the helicopter cockpit display control system is to collect the information of the airborne sensor,the navigation information and the information provided by the mission system,after the data processing and information fusion processing,and then display information to the pilot.Since the existing electronic flight display products can not meet the requirements of the customer,so it is required to develop a new type of electronic flight display.This paper briefly describes the development of the aviation instrument system and the related technology that used to develop the electronic flight display,describes the general design of the electronic flight display,explains the design of I/O interfaces and data transmission channel,and introduces the development process of the interactive human machine interface,so to give a comprehensive and profound explanation and to provide technical accumulation for the development of more complex integrated avionics systems.
