“…Algorithm 1 details the different steps based on the input given by the work of Pornet et al 13 and Cinar et al, 14 which describe a sizing process for electric aircrafts. Respect to the original version, a new analysis is added at step 2; all the other blocks have been indirectly modified due to the presence of the new propulsive architecture.…”

“…3. In previous works on hybrid architectures 13,14 , an hybrid factor has been defined in order to control how much of the total power had to be supplied by each source. In this work, there is no factor splitting the power required from the two sources: with the law presented in Eq.…”

“…There are different types of battery available (such, for example, Li-Ion or Li-S 18 ): in this work it has been decided to use a Li-Ion battery type. A battery is fully defined by a set of five parameters: 13,19,20 • Specific energy density E m , which represents how much energy can be stored in a battery per unit mass (in W h kg −1 );…”

In order to reduce the CO2 emissions, a disruptive concept in aircraft propulsion has to be considered. As studied in the past years hybrid distributed electric propulsion is a promising option. In this work the feasibility of a new concept aircraft, using this technology, has been studied. Two different energy sources have been used: fuel based engines and batteries. The latters have been chosen because of their flexibility during operations and their promising improvements over next years. The technological horizon considered in this study is the 2035: thus some critical hypotheses have been made for electrical components, airframe and propulsion. Due to the uncertainty associated to these data, sensivity analyses have been performed in order to assess the impact of technologies variations. To evaluate the advantages of the proposed concept, a comparison with a conventional aircraft (EIS 2035), based on evolutions of today's technology (airframe, propulsion, aerodynamics) has been made.

“…An under-wing podded twin engine narrow-body transport aircraft retrofitted with a hybrid-electric propulsion was investigated by Pornet et al [21]. The retroïňĄtting of the propulsion system consists of mounting an electric motor powered bybatteries in parallel to the low-pressure shaft of the gas-turbine to supportits operation during some segments of the mission.…”

“…The most common parallel approach is the installation of an electric motor on the low-pressure shaft of a gas-turbine in order to support the operations of the gas-turbine or even drive by itself the propulsor device during segments of the mission [19][20][21][22]. Because of the benefit of utilizing battery on the overall propulsion system efficiency, the electric motor is commonly powered by batteries but the utilization of fuel cells is also conceivable.…”

Following the hybridization or complete electrification strategy of the electric drive pursued on terrestrial vehicles, the aviation industry is considering with great attention the application of electrical technology and power electronics for transport aircraft. The growing interest towards electric application in transport aircraft is driven by the ambitious targets for aviation declared by Europe and by the United-States of America and is motivated by the growing evidence that evolutionary improvement of the technologies might not be sufficient to fulfill these targets. As a result, the introduction of disruptive technologies turns out to be essential. With respect to the progress and perspective in electrical technology, electric drive applications to transport aircraft reveals itself to be a promising field in view of meeting the future goals.The focus of this chapter is the assessment of the electrification of the propulsion system of transport aircraft. While aiming for the ultimate goal of universally-electric aircraft, hybrid-electric approach will be first necessary to match the requirement of aircraft propulsion system and the development pace of the electrical components technology. The combinatorial variety of hybrid-electric and universally-electric propulsion system topology considered for transport aircraft application as well as key enabling technologies are first reviewed. A compendium of hybrid-electric and universally-electric advanced aircraft concepts is then proposed to obtain a notion of the cloud of aircraft configurations and electric drive options investigated up to this point in time. Finally, the integrated prospects of hybrid-electric aircraft are investigated to establish the feasibility of hybrid-electric aircraft for future market segments.Keywords: Hybrid-electric aircraft, Universally-electric aircraft, Hybrid-electric propulsion topology, Battery-fuel hybrid propulsion system, Aircraft conceptual design, Aircraft Sizing, Aircraft Performance IntroductionFollowing the hybridization or complete electrification strategy of the electric drive pursued on terrestrial vehicles, the aviation industry is considering with great attention the application of electrical technology and power electronics for transport aircraft.
