The Design of the The Electrical Structure Network(ESN)of the Civil Aircraft
SUN Jian-yu;Shanghai aircraft design and Research Institute of structural design;
An stable electrical network which has low resistances must be constituted of high conductive structures for any electrical and electronic equipments on civil aircraft, which provides electrical functions such as grounding、bonding、voltage reference、protection from electromagnetic interference and protection against lightning strike. A conventional metallic aircraft inherently provides electrical a high conductive network; at present the advanced composite aircraft requires additional electrical structure network(ESN) to provide electrical functions, due to poor electrical conductivity of composite structures compared to metal. the text introduces the electrical structure network designing for main models of the civil aircraft at present, and summarizes and concludes a general design method for the electrical structure network of civil aircraft, guiding the development of the civil aircraft in our country.
