This work is focused on the study of the combustion mechanism of a class of fast-burning fuels, the so-called liquefying fuels, in hybrid rocket engines. The typical diffusive flame of this kind of propulsion technology brings to poor regression rate

Despite the fact that hybrid propulsion offers significant benefits, it still suffers from some limitations such as the natural oxidizer to fuel ratio shift which induces variations of the engines’ performances while operating. To overcome that iss
