Special Issue Information
Dear Colleagues,
Smart actuation and flow control technologies for next-generation aircraft propulsion systems leverage both active and passive actuators to create engines and airframes that continuously optimize their aerodynamic and thermodynamic environments. Passive actuators, such as compliant morphing structures, bistable surfaces, and flow-responsive micro-flaps, automatically adapt to pressure fluctuations, controlling wing turbulence and near-wall flow dynamics, and mitigating drag losses without requiring continuous power. These are complemented by high-bandwidth active actuators, including piezoelectric and plasma actuators, active shape-memory alloy elements, and electro-hydrostatic micro-servos, that deliver targeted flow injections to control separation, delay stalling, and stabilize compressor stages. The integration of distributed sensing, adaptive algorithms, and digital twins allows these actuators to coordinate across the wing–engine system, potentially leading to quieter operation, reduced fuel burn, lower emissions, greater resilience to gusts and crosswinds, and an improved performance during off-design maneuvers. This Special Issue collection will cover the key findings, advancements, and challenges of these smart actuation systems and how they enable a new class of propulsion airframe architectures that are lighter, more efficient, and capable of meeting the environmental and operational demands of future aviation.

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 250 words) can be sent to the Editorial Office for assessment.
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. Actuators 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.
