Case Study

MULTI FUNCTION DISPLAY FOR FIGHTER AIRCRAFT

An agency tasked with the development of combat aircraft affiliated to defence research organisation.

As part of “fly by light” avionics technology initiative, the customer wanted to develop a “Mission and Display” subsystem targeted for indigenous fighter aircrafts. The scope included the development of Smart Multi Function Displays and Head Up Displays that supported ARINC 818 fibre optic interface.

Solution Methodology

The Aerospace Business Unit of NeST Digital developed a Smart Multi-Function Display and Head up Display POCs that supported ARINC 818 fibre optic interface, Ethernet interface as well as serial port communication for communicating with the subsystems and Mission Computer. The display system used COTS processors and FPGA to implement the solution.

The implementation aimed at fast, reliable and latest technology communication interface between mission computer and display systems for aircraft avionics.

Brief description of product:

  • Hardware
    • multifunction display
    • head-up display unit
    • communication protocol: ARINC 818 over optical fibre
  • Software
    • C++
  • Compliance
    • DO-160, MIL-810F, MIL-461

  • The “fly by light” technology, which is proving to be the next generation technology in Aerospace domain, helps achieve major reduction in aircraft weight by replacing the copper wire-harness; it also increases the real-estate space available in the avionics bay to accommodate additional capabilities.

  • The optical communication system, being immune to Electromagnetic interference improves the aircraft safety standards and the effort required in qualification requirements for airworthy systems.

  • The redundancy achieved by replacing one set of copper cables with OFC and keeping the other set of Copper wire as standby improves system reliability.
