“…The term distributed propulsion (DP) refers to the use of multiple propulsive units, i.e., fans or propellers, hereafter generally referred to as 'thrusters', having the primary aim of providing the thrust necessary for the aircraft to fly in the different operating phases [135][136][137]. The minimum number of propulsive units required to define DP is not distinctively defined in the literature; according to [138] a minimum number of three propulsive units is sufficient to use the term DP, whereas according to ref.…”

The aim of this review paper is to collect and discuss the most relevant and updated contributions in the literature regarding studies on new or non-conventional technologies for propulsion–airframe integration. Specifically, the focus is given to both evolutionary technologies, such as ultra-high bypass ratio turbofan engines, and breakthrough propulsive concepts, represented in this frame by boundary layer ingestion engines and distributed propulsion architectures. The discussion focuses mainly on the integration effects of these propulsion technologies, with the aim of defining performance interactions with the overall aircraft, in terms of aerodynamic, propulsive, operating and mission performance. Hence, this work aims to analyse these technologies from a general perspective, related to the effects they have on overall aircraft design and performance, primarily considering the fuel consumption as a main metric. Potential advantages but also possible drawbacks or detected showstoppers are proposed and discussed with the aim of providing as broad a framework as possible for the aircraft design development roadmap for these emerging propulsive technologies.

Environmental movements of the late 20th century resulted in sweeping legislation and regulatory actions to reduce the prevalence of diverse pollutants. Although the consequences of noise pollution to public health, the environment, and the economy have been recognized over the same time period, noise has received far less policy attention. Correspondingly, even while recent decades have seen robust advancements in assessing the impacts of noise pollution, solutions and actual reductions in environmental noise have remained seemingly out of reach. To address this shortcoming, we developed a prospectus for environmental noise reduction through technology-forcing policies. Technology-forcing describes intent to encourage technological solutions for pollution control through policy and regulations, and has been a critical component of national and global progress in reducing environmental pollutants. We take advantage of the unique policy history for noise in the United States - which initially enacted, but then abandoned federal noise regulation. We compare this history against outcomes from contemporaneous environmental legislation for air, water, and occupational pollution control, to demonstrate the potential for technology-forcing to reduce noise pollution. Our review then identifies promising solutions, in the form of existing technologies suitable for innovation and diffusion through technology-forcing regulations and incentives. Based on this review, we outline a program for noise policy development that is intended to support efforts to reduce environmental noise pollution worldwide. The proposed program consists of three steps, 2 which are to (i) identify dominant sources of noise pollution, (ii) combine legislative or regulatory provisions with suitable systems of enforcement and incentives, and (iii) anticipate and prepare for stages of technological change. This work is intended to support and advocate for noise policies designed around technology-forcing, to advance technologies that not only improve public health and sustainable development, but ensure that these benefits are distributed equitably.

<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>
