Developing Electromagnetic Compatible Commercial Aircraft Engine Cable Harnesses: Trends and Prospects

Advancements in electrified and intelligent technologies require commercial aircraft engines to function reliably and durably in electromagnetic (EM) environments. To mitigate EM disturbances to signal transmissions in commercial aircraft engine cable harnesses, this paper proposes a framework that illustrates the prospects aligned with the systems engineering trend for developing EM compatible cable harnesses using integrated multidisciplinary modelling. Extracting empirical engineering experience, the framework begins by comprehensively identifying intrinsic and external factors and their interacting relationships influencing the induced EM responses in aircraft engine cable harnesses. Subsequently, this framework proposes promising mechanism-based modelling for respectively analyzing the three intrinsic factors, including parameterization-based geometry-topology modelling, heterogeneous material constitutive modelling, and cable harness nonlinear shielding, as well as three external factors, including coupling mechanisms with airborne interface loadings, coupling mechanisms with EM excitations, and numerical analysis techniques for evaluating induced EM responses. This framework outperforms conventional empirical experience-based single-aspect-oriented approaches with more sufficient mechanism-based justification, highlights the trends and prospects of analyzing EM responses from multidisciplinary perspectives, and ensures the function and performance reliability of newly developed commercial aircraft engines, which contributes to flight safety and competency in global aviation market competition.
