Dear colleagues,
Hybrid-electric propulsion is growing increasingly relevant in the aeronautical segment. New propulsive concepts are developed with different levels of electrification up to full electric propulsion. These concepts will probably represent the future of aeronautics, giving researchers new ways to optimize the aircraft, reducing polluting emissions and improving its environmental compatibility.
These new propulsion technologies have some important effects on the overall aircraft design. The electric propellers or fans can be designed and installed, enhancing the aerodynamic qualities of the aircraft, decreasing the induced drag of the wing and the fuselage drag and accelerating the boundary layer. Other concepts of distributed propulsion allow us to increase the wing lift, shorting the takeoff and landing distances.
The short takeoff and landing capability and the reduction of noise and polluting emissions allow this new aircraft capacities to operate outside congested airspaces. Being able to use small airports may reduce the passengers’ door to door time. New business strategies can be envisaged as well.
However, the hybrid-electric propulsion cannot be developed without the improvement of all aircraft systems and specific equipment. A lot of effort is spent to increase the battery energy density and electric motor power density to achieve the necessary mass reduction. All the aircraft systems are moving towards a deep electrification with increased voltage to simplify their architecture and improve their efficiency.
All your contributions will be very welcomed to improve this new and engaging branch of aerospace science.

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.
