The Use of Radar Absorbing Materials to Reduce Crosstalk in the Aircraft Electrical System Circuits
Keywords:
aircraft, crosstalk, radar absorbing material, electrotechnical complex
Abstract
High-frequency electromagnetic interference is induced in the electrical circuits of aircraft electrical systems under the influence of external electromagnetic fields penetrating into the aircraft structure through the aircraft body’s radio-transparent parts. High-frequency interference propagates in the electrical system circuits through cross capacitive and inductive links, as well as due to electromagnetic field radiation by the conductors of electrical bundle communication lines. To weaken cross links and, accordingly, to reduce the crosstalk level, the communication lines in electrical bundles are shielded with braid or solid screens. The crosstalk can be weakened and its propagation paths in the communication lines of electric bundles and the circuits of on-board electrical system’s instruments and devices can be eliminated, apart from shielding, by using radar absorbing materials. The placement of radar absorbing materials in close proximity to the communication line conductors makes it possible to attenuate crosstalk by absorbing the energy of the electromagnetic fields they produce. By using the experimental study results presented in the article it is possible to evaluate the effectiveness of crosstalk attenuation in the frequency band 10–3000 MHz by using a radar absorbing material. The use of radar absorbing material makes it possible to achieve a reduction in the crosstalk voltage between the communication lines in the electrical bundle by 20–30 dBμV.
