Electro-Impulse DeIcing (EIDI) was recently developed and tested with very encouraging results. Questions remain, however, regarding the fatigue life and electromagnetic compatibility of the system. Fatigue tests were conducted on two production aluminum wing leading edges and one composite material leading edge. These were done at realistic temperatures and impulse energies for an estimated aircraft lifetime of ice protection. Coil mounting brackets were the main casualties. Wing components did not fail. Tests were also conducted for metal and composite wings of electromagnetic radiation of EIDI over a wide frequency range. The aluminum wing was found to be an excellent shield. All wires external to the aluminum wing were shown to require careful shielding. The composite wing required all wiring and the metal doublers to be shielded and grounded.
