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.

The increasing environmental concern during the last years is driving the research community towards reducing aviation’s environmental impact. Several strict goals set by various aviation organizations shifted the research focus towards more efficient and environmentally friendly aircraft concepts. Boundary Layer Ingestion (BLI) is currently investigated as a potential technology to achieve different design goals such as energy efficiency improvement and noise emission reductions in the next generation of commercial aircraft. The technology principle is to place the propulsive unit within the boundary layer generated by the airframe body. Although several studies showed its theoretical benefits, a multidisciplinary nature is introduced in the design phase. This imposes new challenges on the current design tools. An increasing number of publications are focusing on assessing this technology while taking into account interlinks between different disciplines. The goal of this work is to review the current state-of-the-art of BLI evaluation studies. Particular focus is given to the underlying assumptions of each work, the methodology employed, and the level of fidelity of the tools used. By organizing the available work in a comprehensive manner, the up-to-date results are interpreted. The current trends and trade-offs emerging from studies are presented. Through reviewing the ongoing published work, the next steps for further development of the methods that will assess this technology are derived.

The electrification of power and propulsion systems on aircraft is a key enabler for the decarbonisation of aviation. A significant challenge for the design of these electrical power systems is that electrical propulsion is a disruptive technology, with neither the associated electrical power system (EPS) architectures nor industry standards established. Compared to conventional, state-of-the-art aircraft, these next-generation aircraft necessitate much more interdependent design of different systems and sub-systems. As such, the efficient design and downselection of an EPS which meets both performance (e.g. weight) and dynamic functionality requirements is challenging. This paper builds on a pre-existing, hierarchical-based EPS modelling framework developed by the authors to present a new design methodology which also incorporates bi-directional interfaces between EPS performance and dynamic functionality, and EPS and non-electrical systems design. The methodology is demonstrated for interdependent electrical power and nonelectrical power systems design, through a case study focussing on the development of a fault management strategy for an EPS integrated with a carbon fibre reinforced polymer structure on a concept electrical vertical take-off and land aircraft.
