Накратко на български

Електромагнитната съвместимост на самолети от нано- и микроструктурирани композитни материали се анализира чрез нов софтуерен модел. Това помага на инженерите да предвидят сривове в системите още при проектирането, вместо да откриват проблеми след производството.

A Fast Numerical Solver for Electromagnetic Compatibility Assessment of Aircrafts Made Using Nano- and Micro- Engineered Materials

Electromagnetic interference (EMI) represents a significant threat to aircraft safety, potentially causing critical system failures during flight. While metals have long been the preferred choice for EMI shielding due to their effectiveness, the aviation industry is increasingly turning to composite materials like carbon fiber composites (CFC) and carbon fiber reinforced carbon composites (CFRC) to achieve weight reduction, improved fuel efficiency, and cost savings. Despite their advantages in weight, corrosion resistance, and impact strength, these composites fall short in EMI shielding capabilities, emphasizing the need for innovative solutions. As the industry incorporates lighter materials and explores advanced nano- and micro-engineered options, thorough assessments of electromagnetic performance are crucial for identifying vulnerabilities. Typically, electromagnetic compatibility (EMC) evaluations are conducted late in the manufacturing process, leading to costly redesigns if problems are discovered. In response to these challenges, the SolvEMCA2 project aims to develop an accelerated numerical solver for assessing EMC in aircraft built with advanced materials, empowering engineers to predict electromagnetic challenges early in the design phase and enabling informed decision-making while simulating in-flight conditions that may not be achievable in experimental settings. The following points are therefore addressed within SolvEMCA2: -Characterization of electric and magnetic behaviour of new EMI shielding materials -Integrating the material into actual Computer-Aided Design (CAD) aircraft models -Accelerating numerical solver for simulating electromagnetic wave propagation through materials These investigations aim to provide a valuable tool and design guidelines for the development of future aircraft, incorporating new materials and technologies for effective EMI shielding.

Цел на проекта

The electromagnetic compatibility (EMC) certification methods of aircrafts are predominantly based on experimental testing to fulfill some standard (e.g. DO-160). This phase involves costly measurement techniques, and high rework costs are required when EMC weaknesses and vulnerabilities are detected, especially at late development stages. To alleviate this situation, numerical solvers are increasingly considered to complement and support experimental means. Numerical solvers enable the engineer to address the full complexity of a problem, and to better understand the impact of changing key parameters in shielding. In this work, we will address two challenges currently identified by aeronautic industry. First, we will develop suitable macroscopic models of novel nano- and micro- engineered smart materials used jointly with Carbon Fiber Composite (CFC) ones, to be used in full-wave numerical solvers in general, and specifically in the Finite-Difference Time-Domain (FDTD) method. For this, we will start from their microscopic structure to get realistic macroscopic electric and magnetic dispersive iso/anisotropic (and eventually non linear) constitutive parameters. Second, specific subcell models of junctions, slots, gaps, curvatures, etc. will be devised for their implementation into FDTD, to prevent brute-force simulation approaches of geometrically involved parts of the aircraft, otherwise computationally prohibitive. As a result, the FDTD method will be endowed with the capability of simulating realistic EMI problems of a whole aircraft with affordable computational resources, in terms of memory and CPU time, including CFCs and novel smart materials, with all geometrical fine details relevant from the electromagnetic point of view.
