Electric Power Systems in More and All Electric Aircraft: A Review

Narrow body and wide body aircraft are responsible for more than 75% of aviation greenhouse gas (GHG) emission and aviation, itself, was responsible for about 2.5% of all GHG emissions in the United States in 2018. This situation becomes worse when considering a 4-5% annual growth in air travel. Electrified aircraft is clearly a promising solution to combat the GHG challenge; thus, the trend is to eliminate all but electrical forms of energy in aircraft power distribution systems. However, electrification adds tremendously to the complexity of aircraft electric power systems (EPS), which is dramatically changing in our journey from conventional aircraft to more electric aircraft (MEA) and all electric aircraft (AEA). In this paper, we provide an in-depth discussion on MEA/AEA EPS: electric propulsion, distributed propulsion systems (DPS), EPS voltage levels, power supplies, and EPS architectures are discussed. Publications on power flow (PF) analysis and management of EPS are reviewed, and an initial schematic of a potential aircraft EPS with electric propulsion is proposed. In this regard, we also briefly review the components required for MEA/AEA EPS, including power electronics (PE) converters, electric machines, electrochemical energy units, circuit breakers (CBs), and wiring harness. A comprehensive review of each of the components mentioned above or other topics except for those related to steady state power flow in MEA/AEA EPS is out of this paper's scope and should be found somewhere else. At the close of the paper, some challenges in the path towards AEA are presented. Unless the discussed challenges are satisfactorily addressed and solved, arriving at an AEA that can properly operate over commercial missions will not be possible. INDEX TERMS aircraft electrification, all electric aircraft (AEA), electric power system (EPS), more electric aircraft (MEA), power distribution system, steady state power flow analysis.

“…In this letter, a direct method described in [8] and an iterative method (the Gauss-Seidel method) are applied to solve (2) and (3). When the direct method is used, E y n (i, j + 1/2, k) and E y n −1 (i, j + 1/2, k) are employed in (2) instead of E y n (i + 1/2, j, k) and E y n −1 (i + 1/2, j, k), which are not located on the FDTD electric-field grid, and E x…”

“…Apra et al [1], using the finite-difference time-domain (FDTD) method [2], have analyzed transient magnetic fields and voltages induced on cables in a CFRP-made aircraft struck by lightning. Perrin et al [3] have carried out a similar FDTD computation for estimating currents induced on cables in a CFRP-made aircraft struck by lightning. In analyzing lightning-induced effects on electrical or electronic systems in a CFRP-made aircraft, it is sufficient to represent the aircraft body as a uniform bulk material as done in [1] and [3].…”

However, in studying thermal sparks, which would occur on or in the CFRP material of the aircraft struck by lightning and might cause fuel explosion, the layered structure of CFRP needs to be considered.…”

The transient distribution of lightning current, which flows in a multilayer carbon-fiber-reinforced plastic (CFRP) material of aircraft, has been studied using the finite-difference timedomain (FDTD) method. Each layer of the multilayer CFRP panel has a fiber direction of 45°, 90°, -45°or 0°, and, therefore, has an anisotropic conductivity: the conductivity is high in the fiber axial direction and low in other directions. It is impossible to represent such an anisotropic layered panel using the FDTD method with common rectangular prism or cubic cells. In this letter, two approaches are employed: one is the application of conductivity matrix having off-diagonal elements and the other is the application of triangular-prism cells. The transient distribution of the magnetic field over the surface of the CFRP panel, computed with the former approach, is compared with that computed with the latter approach. Also, the results are compared with the corresponding measured ones.

“…As early as in 1946, the lightning institute was established. The nature and mechanism of the lightning phenomenon were studied and the relevant protection methods were discussed [12][13][14][15][16][17]. Hirano et al [18] studied the damage of composite laminates under different pulse waveform of lightning current and detected the internal damage of laminates by nondestructive testing technology.…”

Lightning Performance of Copper-Mesh Clad Composite Panels: Test and Simulation

：According to simulation lightning experiments and eddy current analysis results, a three-dimensional finite element model of composite laminated plates with shield is established. By applying electric-thermal boundary and the coupling relationship between them, the lightning strike damage results under the protection of shield are realistically simulated with the commercial finite element analysis software, ABAQUS. Considering the coupling effect of heat, electricity, and force during lightning strike, the load distribution field of copper mesh and carbon fiber panel with lightning current inducted is analyzed. Comparing the thermal stress distribution of the specimen surface under various current loads, it is shown that the stress of carbon fiber panel is significantly lower than the one of the copper screen when the specimen structure suffers heavy current, since the copper network plays a role of endergonic protection. Simulation data are consistent with the test results, thus the method can be used for other similar research.
