“…On the other hand, the CFDs simulations using the actual scale and flight conditions of the aircraft demonstrated a power-saving coefficient of about 6.52%, as shown in [22]. This result is not plotted in Figure 12, because it cannot be compared directly to the power extracted from the wind tunnel experiments.…”

“…Two experimental setups were employed to investigate the aerodynamic interaction of the box-wing layout with the propulsion system: one focusing on the effect of podded engines on the airframe and one investigating boundary-layer ingestion inlets. The experimental data were used to validate preliminary CFDs studies [22], which were in turn used to perform sensitivity studies and complement the low-fidelity design of the concept. The experimental study included force and electrical power measurements, flow mapping, and total pressure surveys.…”

The aerodynamic design of a new aircraft concept was investigated through subsonic wind-tunnel testing using 1:28-scale powered models. The aircraft configuration integrates a box-wing layout with engines located at the rear part of the fuselage. Measurements involved a back-to-back comparison between two aircraft models: a podded version whose engines were assembled on pylons and a boundary-layer ingestion (BLI) version that provided several system-level benefits. The flowfield was investigated through the power balance method and a variety of pressure flowfield and inlet flow distortion metrics. The results proved that the BLI configuration enhances the propulsive efficiency by reducing both the electrical power coefficient and the kinetic energy waste due to lower jet velocities. Furthermore, there was a reduction of the total pressure recovery due to pressure gradients inside the duct, thereby causing high distortion. Overall, this research highlights the importance of wind-tunnel testing to bring any aerodynamic technology to a sufficient level of maturity and to enable future new aircraft concepts.

“…As the aviation industry embraces innovative solutions for efficiency and sustainability, the power balance method stands as a guiding framework, driving progress and unlocking the full potential of the BLI capabilities of different non-conventional concepts. A more recent investigation applying this method was presented by Bravo-Mosquera et al [239,240]. These articles describe computational and experimental investigations of a non-conventional transport aircraft which combines a box-wing layout with a BLI propulsion system (Figure 59).…”

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.

“…To achieve this ambitious goal, new technologies must be adopted concurrently with breakthrough aircraft configurations. The investigation of new configurations is reflected in the effort of the scientific and industrial communities: many studies have concentrated on the study of the Blended Wing Body (BWB) [4][5][6][7][8][9], the Truss Braced Wing (TBW) gained popularity as well [10][11][12][13], a more exotic V-shaped configuration was presented and is under development [14], as well as the box wing or PrandtPlane configuration [15][16][17][18] and many others.…”

This paper presents a preliminary study on the improvement of the fuel efficiency of a civil transport aircraft, focusing on the aero-elastic optimization of an increased aspect ratio wingbox. The wing is stretched, increasing its aspect ratio, and a trade-off between the improved aerodynamic efficiency and the structural mass identifies an optimal aspect ratio for such aircraft. The aeroelastic optimization is performed with NeOPT, a structural optimizer for conceptual and preliminary design phases. The analysis considers different materials and structural solutions for the wingbox and tackles aeroelastic constraints, such as flutter and aileron efficiency, from the preliminary design phases. The fuel consumption of the sized aircraft is evaluated with a simplified approach that provides an indication of the fuel efficiency. The results show how a composite wing with increased aspect ratio can save up to 6.9% of fuel burnt with respect to the baseline aluminum wing. The results are extended at fleet level, achieving a 2-million-ton cut in CO2 emissions and a saving of USD 1.28 million on fuel-related costs.
