Transonic Flow (2nd Edition)

Dear Colleagues,

Transonic flow research has been of critical importance since the development of high-speed propellor aeroplanes and turbojet engines in the mid-1940s. The transonic flow regime has been, and remains, a challenge both for computational prediction and experimental simulation. The close coupling of shock waves, arising from the compressibility of air, and the effects of viscous flow on aircraft surfaces lead to highly unsteady and complicated flows that often involve detrimental flow separations. These can result in unsteady loading, potentially causing structural vibrations of aircraft components. An understanding of unsteady transonic flow is therefore fundamental to the safe design of high-speed aircraft.

Today’s aircraft industry is required to develop revolutionary new aircraft concepts to address the aviation impact on climate change and noise. This involves driving reassessments in design philosophy to achieve step changes in aerodynamic and propulsive efficiency, involving a much closer coupling of aircraft fuselage, wings, and engines. Emerging data on the transonic performance of these revolutionary designs have revealed how different the flows are to those associated with conventional tube and swept-wing designs.

Transonic flow research therefore remains critical to the development of high-speed aircraft today, and it is fitting that this Special Issue of Aerospace is devoted to this important topic.

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.
