Aero-engines are mandatory for the planned development of civil transport aviation of the 20s and the 30s of the 21st century. The absolute need for engines to reach this increased number of passengers is twofold, with a further reduction of the fuel burn (with a lower TSFC) and a drastic reduction of the emissions, namely air pollutants and noise. This Special Issue will cover two objectives covering these needs, as follows: it will examine in detail the requested aero-engine cycles and architecture that can bring about the needed fuel consumption reduction per passenger, and it will review the technological solutions bringing about the imposed reduction of air pollution and noise.
The first part of the Special Issue covers the quest for lower TSFC (or SFC), and even more specifically of the fuel burn per passenger and mile (km). The new and future aero-engine cycles and the related organization and architecture will be studied and analyzed in detail, with focus on the different components that must be improved and vastly updated compared with the current aero-engine sub-systems. The Special Issue will go through the innovations needed in the design of the cowls and nacelles, fan blades for UHBPR engines, gearboxes of GTF engines, high-speed boosters, ultra-high pressure ratio’s, and high speed LPT design, but also of the high-speed propellers with aft-mounted counter-rotating blade rows as open rotors (or unducted fans) or more classical propfans.
The second part of the Special Issue covers the technological development required to reduce the emissions of these new aero-engines even further, namely: lower greenhouse gas emissions, lower NOx, or new fuels as synthetic fuels or hydrogen, but also to reduced noise emissions at take-off and landing and during the climb.

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.
