“…The takeoff speed analysis showed an average of approximately 180 km/h, mainly between 170 and 190 km/h, aligning with existing technical data [25]. For power requirements, the study assumed maximum motor output during takeoff, a common approach in aviation research [24], [26], [27], resulting in 32 seconds of full power for this phase. 6-(c).…”

<p>All-electric battery-powered aircraft have, over the last couple of years, had a clear path toward commercialization by the end of this decade. However, the development of smaller all-electric commuter aircraft has recently stagnated due to inherent technical limitations. To gain deeper insights into these challenges, this paper provides a detailed powertrain analysis of 9- and 19-seat all-electric commuter aircraft. Real-world mission profile data, obtained from 1500 flights in the Norwegian short-haul commuter network, are used as inputs. Regression analysis reveals that the cruising power needed is only about \SI{43}{\%} of the power needed for takeoff and climb. This work presents a comprehensive component-level weight distribution analysis of the all-electric powertrains investigated, and the required weight is shown to exceed the manufacturers' reported maximum takeoff weight (MTOW) of the two reference aircraft studied. However, small improvements in component performances could make electrification of the short-haul commuter network feasible, which is highlighted in a sensitivity study of the most critical electrical components. Additionally, our study highlights that the shortest missions are actually dimensioned by power rating rather than energy storage, adding an extra constraint on battery sizing for the shortest trips. </p>

“…other electrical components, the range of the operating temperature of the battery is narrower, usually within 15-45 °C [25]. While ensuring the battery temperature does not exceed the maximum temperature, an active temperature control might be required under low-temperature conditions to ensure the temperature is above the minimum temperature.…”

Projects related to green aviation designed to achieve fuel savings and emission reductions are increasingly being established in response to growing concerns over climate change. Within the aviation industry, there is a growing trend towards the electrification of aircraft, with more-electric aircraft (MEA) and all-electric aircraft (AEA) being proposed. However, increasing electrification causes challenges with conventional thermal management system (TMS) and power management system (PMS) designs in aircraft. As a result, the integrated power and thermal management system (IPTMS) has been developed for energy-optimised aircraft projects. This review paper aims to review recent IPTMS progress and explore potential design solutions for civil aircraft. Firstly, the paper reviews the IPTMS in electrified propulsion aircraft (EPA), presenting the architectures and challenges of the propulsion systems, the TMS cooling strategies, and the power management optimisation. Then, several research topics in IPTMS are reviewed in detail: architecture design, power management optimisation, modelling, and analysis method development. Through the review of state-of-the-art IPTMS research, the challenges and future opportunities and requirements of IPTMS design are discussed. Based on the discussions, two potential solutions for IPTMS to address the challenges of civil EPA are proposed, including the combination of architecture design and power management optimisation and the combination of modelling and analysis methods.

To investigate the key enabling technologies for hybrid-electric regional aircraft, several assumptions about the maturity and required level of technology are necessary. Within the EUfunded project FutPrint50, a decision-making framework based on Set-Based Design principles is being developed to address these uncertainties arising from operational requirements and technological feasibility levels. The methodology has been applied to study the effects of the energy storage durability and technology level on the energy management strategies of a regional hybrid-electric aircraft. Results highlight the key role of battery energy density on the durability of the battery pack and the viability of the hybrid-electric aircraft concept. Additionally, the trade-off between zero-day environmental compatibility and battery lifetime is identified alongside its causing mechanism. Optimal energy management strategies are suggested in light of this new information. Finally, statistical data of cell energy density is used to estimate the most probable year of feasibility of hybrid-electric propulsion for regional aircraft.
