• Abstract:
  An important consideration in the certification of Electro-impulse De-icing (EIDI) systems for aircraft ice protection is electromagnetic interference (EMI). When the capacitor bank in an EIDI system discharges a large pulse of current travels down a transmission line to the coil. Subsequent radiation by the transmission line and the coil produces EM!. The Low Voltage Electro-Impulse De-icing system (LVEIDI) is unique in that the capacitor bank is mounted adjacent to the coil thereby eliminating most of the cables. Electromagnetic emissions from this system would than be primarily from the coil. The performed tests investigate the EMI environment inside and outside of both a composite and an aluminum wing. Due to the absence of the shielding effect of aluminum the problem of electromagnetic emissions is particularly severe when the wing is constructed of composite materials.
