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 engine (HRE) performance is dependent on fuel/oxidizer selection and fuel
grain geometry. A literature review was performed to identify key trends and findings related …

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 …

Paraffin-based fuel is a promising and low-cost alternative for hybrid rocket motor
applications due to its advantage of high regression rate. Meanwhile, paraffin fuel alone has …

An attempt has been made in the present study to realize the effect of multi-location swirl
injection on the improvement of regression rate and combustion efficiency of hybrid rocket …

Paraffin-based fuels are regarded as a promising solid fuel for hybrid rocket motor (HRM)
owing to high regression rate, excellent mechanical performance, and high dropping point …

In the present study, attempts were made to compare the influence of protrusion method on
the performance of liquefying and non-liquefying fuels which has different combustion …

The present study explores the influence of protrusions on the combustion stability of a
hybrid rocket motor. The primary aim is to analyze single, double, and triple-protrusion …

This paper examines the effect of single protrusion and multiprotrusion on the performance
of hybrid rocket with the length/initial port diameter (L/D) ratio of 12.5. The fuel used was …

This paper extensively reviews hybrid rocket propulsion-related activities from combustion
engine designs to launch tests. Starting with a brief review of rocket propulsion development …
