High Reliability Avionics at Northrop Grumman Electronic Systems
Keywords: High Reliability, Thermal , FRACAS
Delivering high reliability avionics systems to our military customers requires a multi-faceted approach and a firm commitment to the highest quality standards. Reliability is a Key Performance Parameter (KPP) on all of our systems - it depends strongly on the specific mission for the equipment - and it is the degree to which a system is available for use, is safe to install, test, operate, and repair [1]. This presentation will highlight some of the reliability processes used at Northrop Grumman, starting with a clear understanding of the customers' requirements and ending with performance tracking of fielded systems. In between are processes such as a commercial component approval procedure, detailed thermal and structural analyses, detailed reliability and life predictions, design verification and qualification testing, and FRACAS (Failure Reporting, Analysis, and Corrective Action). This presentation will also include real life examples of how Northrop Grumman tackled tough reliability requirements for radar systems on the F-16 and F-22.
