The focus of this review is to collect and compare research studies on hybrid rocket fuels
and components produced via additive manufacturing. The use of hybrid rocket propulsion …

Hybrid rocket propulsion, first demonstrated by the Russian GIRD-09 rocket in 1933,
combines liquid oxidizer and solid fuel for thrust generation. Despite numerous advantages …

This paper presents the status of developments worldwide regarding use of hybrid rocket
motors for space transportation. Historical roots are presented and reasons for revisiting …

Slow regression rate of the solid fuel is the main limitation for the use of hybrid rocket
engines in high thrust applications. Paraffin-based fuels tackle this limitation thanks to the …

Hybrid rocket fuel average regression rate is one of the most important values to accurately
determine in the hybrid rocket design process and for rocket performance prediction. Yet …

In this work, we assess the impact of stepped hybrid rocket solid fuel grains on the
performance of the engine. The influence of Forward Facing Steps (FFS) and Backward …

Paraffin wax as a hybrid rocket fuel has not been comprehensively characterised, especially
regarding the structural feasibility of the material in launch applications. Preliminary …

The combustion behavior of paraffin-based hybrid rocket fuels with gaseous oxygen as an
oxidizer has been analyzed in detail. Regression rate tests have been done in a two …

An experimental performance evaluation, conducted with static firings of a laboratory-scaled
hybrid rocket burning gaseous oxygen and several fuel combinations, aimed at raising the …

Hybrid rockets have many advantages over pure solid or liquid propellant rockets, but low
solid fuel regression rates and correspondingly low thrust have hindered their application to …
