Special Issue Information
Dear Colleagues,
Hypersonic flight, a frontier in aerospace engineering, promises to revolutionize space launch, global transportation, and defense applications. The development of reliable and efficient hypersonic vehicles, however, presents formidable scientific and engineering challenges. The extreme conditions encountered—including intense aerothermal loads, complex shock-wave/boundary-layer interactions, and real gas effects—demand a deep and nuanced understanding of the underlying flow physics.
As a key option for hypersonic propulsion, the wide-range ramjet engine is designed to achieve stable and efficient operation across a broad velocity range, from low-Mach-number launch to high-Mach-number cruise, making it a core technology for missions such as single-stage-to-orbit and long-range rapid strike. Its primary challenge lies in achieving a smooth and reliable transition between different combustion modes. Concurrently, the Rocket-Based Combined Cycle (RBCC) engine represents another critical pathway, integrating rocket and air-breathing cycles. Understanding the fundamental mechanisms governing flow pattern stability, mixing enhancement, and hysteresis effects during mode transitions is crucial for optimizing engine performance.
Another significant challenge lies in the guidance and control of these vehicles. Operating in flight environments with high dynamics and severe constraints, these systems require highly robust, fast, and precise control laws. A growing area of research is Integrated Guidance and Control (IGC) design, which moves beyond traditional architectures to synergistically optimize guidance and control actions, thereby enhancing agility and precision.

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. 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.
