“…These secondary effects, therefore, could theoretically (partially or totally) undermine the benefit obtainable in terms of specific fuel consumption by increasing the BPR, affecting the overall performance of the whole aircraft (i.e., block fuel consumption). For this reason, in order to effectively foster the development and actual implementation of the UHBR turbofan, in addition to evaluating technological implementations in advanced materials and more efficient components [52], in nacelle design [53,54] and its shape optimization [55,56], it is also crucial to take into account the effects of the turbofan installation [57], together with the mission performance of the complete aircraft [58].…”

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 phenomenology of the interaction between a podded engine and the wing has been described qualitatively and quantitatively in several works based on experimental measurements or CFD analyses [17]. With reference to UHBPR turbofans, the main effect of engine/airframe coupling has been shown to occur in the wing lower side due to jet/surface interaction and flow channelling between the nacelle, pylon, and wing [30]. However, the effect of angle of attack variation at highly subsonic cruise speed is less well documented.…”

Gas turbine fuel burn for an aircraft engine can be obtained analytically using thermodynamic cycle analysis. For large-diameter ultra-high bypass ratio turbofans, the impact of nacelle drag and propulsion system integration must be accounted for in order to obtain realistic estimates of the installed specific fuel consumption. However, simplified models cannot fully represent the complexity of installation effects. In this paper, we present a method that combines thermodynamic cycle analysis with detailed Computational Fluid Dynamics (CFD) modelling of the installation aerodynamics to obtain the fuel consumption at a given mission point. The flow field and propulsive forces arising in a transport aircraft powered by an ultra-high bypass ratio turbofan at cruise are first examined to characterise the operating conditions and measure the sensitivity to variations of the incidence at transonic flight. The proposed methodology, in which dynamic balance of the vehicle is achieved at each integration point, is then applied along a cruise segment to calculate the cumulative fuel burn and the change in the specific fuel consumption.
