Special Issue Information

Dear Colleagues,

Aircraft design is, as we know, the first fascinating step in the life of an aircraft, where visions are converted into reality.

In a practical sense, aircraft design supplies the geometrical description of the aircraft. Traditionally, the output is a three-view drawing and a list of aircraft parameters. Today, the output may also be an electronic 3D model. In the case of civil aircraft, a fuselage cross-section and a cabin layout are additionally provided.

In an abstract sense, aircraft design determines the design parameters to ensure that the requirements and constraints are met and design objectives are optimized. The fundamental requirements for civil aviation are payload and range. Many constraints come from certification rules demanding safety. The objectives are often of a financial nature, such as achieving the lowest operating costs. Aircraft design always strives for the best compromise among conflicting issues.

The design synthesis of an aircraft goes from conceptual design to detailed design. Frequently, expert knowledge is needed more than computing power. The typical work involves statistics, the application of inverse methods, and the use of optimization algorithms. Proposed designs are analyzed with respect to aerodynamics (drag), structure (mass), performance, stability and control, and aeroelasticity, to name just a few. A modern aircraft is a complex, computer-controlled combination of its structure, engines, and systems. Passengers demand high comfort at low fares, society demands environmentally friendly aircraft, and investors demand a profitable asset.

Overall aircraft design (OAD) comprises all aircraft types in civil and military use and considers all major aircraft components (wing, fuselage, tail, undercarriage), as well as the integration of engines and systems. The aircraft is seen as part of the air transport system and beyond, contributing to multimodal transport. Aircraft design applies the different aerospace sciences and considers the aircraft during its whole life cycle. Authors from all economic sectors (private, public, civic, and general public) are invited to submit papers to this Special Issue (SI). Education and training in aircraft design are considered as important as research in the field.

The SI can be a home for those active in the European Workshop on Aircraft Design Education (EWADE) or the Symposium on Collaboration in Aircraft Design (SCAD), both independent activities under the CEAS Technical Committee Aircraft Design (TCAD). Please see http://AircraftDesign.org and http://journal.AircraftDesign.org for details. Prof. em. Egbert Torenbeek served as Honorary Guest Editor for this Special Issue “Aircraft Design” from 2020 to 2022. He resigned from all his duties. Please read about his achievements on https://en.wikipedia.org/wiki/Egbert_Torenbeek.

Following the successful initial Special Issue on “Aircraft Design (SI-1/2017)”, the SI was relaunched with “Aircraft Design (SI-2/2020)” and continued as “Aircraft Design (SI-3/2021)” and “Aircraft Design (SI-4/2022)”. This is now the fifth SI named “Aircraft Design (SI-5/2023)”. The Editorial was published on 14 Jan 2020 as https://doi.org/10.3390/aerospace7010005. It gives the background of publishing in Aircraft Design and gives hints to manuscript submission in Appendix A.

Activities in the past have shown that aircraft design may be a field too small to justify its own (subscription-based) journal. A continuous open access Special Issue may fill this gap. As such, the Special Issue “Aircraft Design” can be a home for all those working in the field who regret the absence of an aircraft design journal.

The Special Issue “Aircraft Design” is open to the full range of article types. It is a place to discuss the “hot topics” (fuel-cell-powered aircraft, aircraft designed for contrail avoidance, aircraft with truss-braced wings, etc.). The classic topics in aircraft design remain:

  • Innovative aircraft concepts;
  • Methodologies and tools for aircraft design and optimization;
  • Reference aircraft designs and case studies with data sets.

It is up to us as authors to shape the Special Issue “Aircraft Design” according to our interests through the manuscripts we submit.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Aerospace is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Present work investigates the potential of a long-range commercial blended wing body configuration powered by hydrogen combustion engines with future airframe and propulsion technologies. Future technologies include advanced materials, load alleviation techniques, boundary layer ingestion, and ultra-high bypass ratio engines. The hydrogen combustion configuration was compared to the configuration powered by kerosene with respect to geometric properties, performance characteristics, energy demand, equivalent CO2 emissions, and Direct Operating Costs. In addition, technology sensitivity studies were performed to assess the potential influence of each technology on the configuration. A multi-fidelity sizing methodology using low- and mid-fidelity methods for rapid configuration sizing was created to assess the configuration and perform robust analyses and multi-disciplinary optimizations. To assess potential uncertainties of the fidelity of aerodynamic analysis tools, high-fidelity aerodynamic analysis and optimization framework MACH-Aero was used for additional verification. Comparison of hydrogen and kerosene blended wing body aircraft showed a potential reduction of equivalent CO2 emission by 15% and 81% for blue and green hydrogen compared to the kerosene blended wing body and by 44% and 88% with respect to a conventional B777-300ER aircraft. Advancements in future technologies also significantly affect the geometric layout of aircraft. Boundary layer ingestion and ultra-high bypass ratio engines demonstrated the highest potential for fuel reduction, although both technologies conflict with each other. However, operating costs of hydrogen aircraft could establish a significant problem if pessimistic and base hydrogen price scenarios are achieved for blue and green hydrogen respectively. Finally, configurational problems featured by classical blended wing body aircraft are magnified for the hydrogen case due to the significant volume requirements to store hydrogen fuel. Full article
