Development of a System Integration Laboratory for aircraft avionics systems

The avionic systems of newly developed aircraft platforms are demanded to be a fully integrated avionics system of enhanced functions supporting the operator for successful mission operations. Prior to its installation to the aircraft, the developed avionics system should have to be fully tested in an integrated lab, SIL (system integration laboratory), to validate its successful integration and demonstrate OFP tests as an integrated avionics suite. Actually, system level test conducted at a system integration laboratory is now mostly required for aircraft development programs or for avionics system upgrade programs. This comes up to a need for developing a SIL system of the MEP system which is being developed for the KUH (Korean utility Helicopter). This paper shows the design results of the KUH MEP SIL system. Requirements for the SIL system and SIL design results are shown. For a better understanding, the MEP system of the KUH is also introduced. The design options that were considered during the design process are shown and compared. The requirements, design results and design considerations introduced in this paper will be able to inspire upcoming similar programs including avionics system upgrade for classical aircrafts.
