Dear Colleagues,

Unmanned aerial systems (UAS) have had a significant influence in the modern period. Due to UAS’s high efficiency and low cost, a great deal of study has been conducted on these subjects. Numerous conveniences, including as parcel transportation, reconnaissance of uncharted regions, and relay communication, have been made possible by UAS. The rapid growth of UAS has resulted in a multitude of unique applications that have, are, and will alter a great number of civil and military aviation traditions. However, the prospective applications of UAS cannot be limited by the current state of research. The most up-to-date approaches and technology are certain to spark fresh ideas or possibly a revolution in UAS’s design and implementation. 

The disciplines connected to design, control, and perception across the academic and industrial spectrum frequently provide new understandings and experiences from the most prevalent use of UAS. In addition, the development of intelligent technology has increased not only the efficacy but also the accuracy of the aforementioned three factors. The most recent advancements in configuration, aerodynamic performance, and structural strength of UAS have provided very compelling evidence that many insights from natural beings can be applied at a very low cost and without causing injury or death, thereby making it possible to relax the rules that must be observed by manned vehicles. Numerous control algorithms may now be tested and implemented in ways that were impossible even a few years ago, allowing them to complete numerous missions that cannot be handled by humans. As sensors become smaller and more precise, UAVs can be outfitted as perceptual units to collect data from inaccessible places and assist or perhaps replace humans in decision-making. Consequently, how UAVs should be used to perceive new environmental data is a very intriguing issue that must be thoroughly investigated to determine its advantages and cons.

Above, we solicit articles that either address the research opportunities described here or that make a substantial addition to the state of the art in the broader field of UAS.

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.
