Special Issue Information

Dear Colleagues,

Micro Air Vehicles (MAVs) have been constantly studied during the last decade. Many of them are now ready and being used for practical applications for both civil service and military surveillance. However, there have recently been challenges in aerodynamic efficiency; both the low Reynolds number and aeroacoustic noise caught our attention when they came into practical application. Therefore, addressing and understanding aerodynamics at a low Reynolds number for aerodynamics enhancement and reducing the perceived noise of micro air vehicles without compromising their aerodynamic efficiency would be crucial in practical missions. This Special Issue of Fluids, entitled “Aerodynamics and Aeroacoustics of Micro Air Vehicles”, aims to collect articles related to aerodynamics and aeroacoustics of micro air vehicles in order to introduce them to readers in relevant research areas. Topics of the Special Issue include but are not limited to, the aerodynamics of MAVs including flapping flight, wing and propeller design for low acoustic signature MAVs, Computational Fluid Dynamic (CFD) simulation, the experiment of aerodynamics and aeroacoustics for MAVs including fixed wings, rotary wings, and flapping wings.

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. Fluids 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 1800 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.

The rapid growth of drone use in urban areas has prompted authorities to review airspace regulations, forcing drone manufacturers to anticipate and reduce the noise emissions during the design stage. Additionally, micro air vehicles (MAVs) are designed to be aerodynamically efficient, allowing them to fly farther, longer and safer. In this study, a steady aerodynamic code and an acoustic propagator based on the non-linear vortex lattice method (NVLM) and Farassat’s formulation-1A of the Ffowcs Williams and Hawkings (FW-H) acoustic analogy, respectively, are coupled with pymoo, a python-based optimization framework. This tool is used to perform a multi-objective (noise and aerodynamic efficiency) optimization of a 20 cm diameter two-bladed rotor under hovering conditions. From the set of optimized results, (i.e., the Pareto front), three different rotors are 3D-printed using a stereolithography (SLA) technique and tested in an anechoic room. Here, an array of far-field microphones captures the acoustic radiation and directivity of the rotor, while a balance measures the aerodynamic performance. Both the aerodynamic and aeroacoustic performance of the three different rotors, in line with what has been predicted by the numerical codes, are compared and guidelines for the design of aerodynamically and aeroacoustically efficient MAV rotors are extracted.
