Helicopters are multi-purpose flight vehicles due to their ability to perform vertical take-off and landing, hovering, and cruise flight at varying speeds. These capabilities are the basis for conducting a unique range of missions from transport up to search and rescue. The forces required for lift and propulsion are created by a rotor consisting of several blades, the number and design of which depending on performance, operational, and mission requirements. Rotor blade aerodynamics phenomena and problems are, among others, related to dynamic stall, Mach number effects, blade-vortex–interaction, transitional flow, and strong interaction phenomena. Methods of aerodynamic drag reduction often concentrate on fuselage and cowling geometries. Rotor and fuselage wake interactions with the stabilizers may cause problems like tail shake. Consequently, a variety of complex aerodynamic interaction phenomena and problems are associated with helicopters addressing a research field of high relevance.

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.
