EMC design of a modern fighter aircraft-a case study

Abstract

A modern fighter aircraft is highly electronic-intensive with large number of equipments and systems. All these systems have to work safely and efficiently in a hostile electromagnetic environment. To achieve this objective it is essential to adopt systematic EMC measures throughout the life cycle of the design and development of a combat aircraft. This paper addresses an integrated approach using a mix of analysis and testing adopted by the EMC design team of Indian Light Combat Aircraft (LCA) Programme in order to achieve an operational aircraft with minimal EMI problems.
