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 …

The idea of the hybrid rocket is to store the oxidizer as a liquid and the fuel as a solid,
producing a design that minimizes the chance of a chemical explosion. While the hybrid …

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 …

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 …

HTPB/paraffin fuels exhibit high regression rates and excellent mechanical properties due to
the droplet entrainment and enhancement of the HTPB matrix, however, the special structure …

Outer planet exploration missions require significant propulsive capability, particularly to
achieve orbit insertion. Missions to explore the moons of outer planets place even more …

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 …

Hybrid rockets using specific oxidizer–fuel combinations are considered a green alternative
to current propulsion systems, as they do not release very toxic or polluting exhausts, but …

Hybrid propellant combinations using nitrous oxide in combination with carbon hydrogen
based fuels have been of high interest for several years due to their high safety and good …
