Abstract

A Hybrid Rocket Engine (HRE) in a conventional way refers to a combination of fuel as solid and oxidizer in the liquid or gaseous phase. This combination has received significant attention in the scientific community due to its intriguing characteristic of reducing chemical explosions and enhancing operational safety. Alongside, the impact on environmental sustainability can be escalated to a reasonable scale. In this context, the current paper emphasizes the major challenges involved with combustion, design of reaction mechanism, low regression rate, choosing the right fuel and poor mechanical properties. This review will help the scientific community to establish a state-of-art technology that would resolve the current challenges to provide a sustainable result. At the same stretch, most of the works haven’t realized this technology to a commercial value. Hence the current review shall focus on the works cited in the global community and lacunae for the transfer of technology-to-technology readiness level.
