Lightweight Electromagnetic Interference (EMI) Shielding System for Aircraft Avionics

A key technology enabler for next generation EMI shielding applications is low loss, lightweight, flexible, conductive carbon nanotube (CNT) tape. The primary goal of this effort is to determine the optimal geometry for a CNT based EMI shield to provide equivalent shielding effectiveness of cable harnesses and other electronics on the V-22 Osprey, while maintaining a maximum weight savings. The approach will include both modeling and experimental data and testing. The modeling of the V-22 will identify key electronic areas of interest, while the experimental data will feed more accurate information into the models to take full advantage of the CNT material"s EMI properties and weight savings. Material development and some testing will be carried out by Nanocomp and the modeling effort along with additional testing will be led by Electromagnetic Applications, Inc. (EMA).
