Special Issue Information
Dear Colleagues,
In recent years, the successful applications of hybrid rocket engines have been gradually attracting the research interest of researchers around the world, such as space tourism and transportation, small launch vehicles, and sounding rockets. Due to their low cost, high safety, lower environmental impact, and high performance, hybrid rocket engines have the potential for rapid development and are favored by private and public entities. In addition, as interest in hybrid rocket propulsion grows among students and amateur rocket developers, hybrid rocket engines will have great prospects for use in next-generation rocket systems. A typical hybrid rocket engine adopts the liquid oxidizer and solid fuel as propellants, which are stored in a tank and combustion chamber, respectively. In hybrid rocket engines, the injected oxidizer and pyrolysis fuel are mixed and burned in the combustion chamber; the combustion model is typical non-premixed diffusion combustion and has unique advantages. In recent research, the key areas are mainly performance enhancement technology, combustion and flow simulation, optimization design, etc.
In this Special Issue, we invite contributions relating to the advancement of hybrid rocket engine technology, including, but not limited to: performance enhancement technology (such as paraffin-wax-based fuel, metallic additives, swirl oxidizer injection, unique grain design), combustion and flow simulation (such as large eddy simulation, dynamic numerical simulation, thermochemical erosion, heat transfer of radiation), molecular dynamics, overall optimization design, multidisciplinary design and optimization, optimization with uncertainty, feeding system design, engine component design, ablation-resistant nozzle technology, electric pump pressurized systems, thrust throttling technology, ignition technology, advanced measurement technology, and novel applications.

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.
