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 …

Hybrid rockets are considered a promising future propulsion alternative for specific
applications to solid or liquid rockets. In order to raise their technology readiness level, it is …

In this work, two representative hybrid rocket injector designs, a single-port and an axial
showerhead design, were examined experimentally to determine the comparative influence …

The function of time-resolved fuel regression measurement is integrated into additively
manufactured hybrid rocket fuels and conceptually demonstrated through the comparison …

This paper discusses the performance characteristics of a paraffin-based blend of liquid
ethanol with paraffin as compared to pure paraffin in a hybrid rocket motor. Since the …

The thermal decomposition of methyl methacrylate (MMA) was studied through species time-
history measurements of formaldehyde (CH 2 O), carbon monoxide (CO), and carbon …

HYBRID rockets are much safer than solid and liquid rockets because the fuel and oxidizer
are physically separated and stored as different material phases. Data reduction in static …

Spectral analyses were performed on high-speed video of three nitrous-oxide/paraffin-
based hybrid rocket launches and one static test fire of a nitrous/paraffin-based hybrid rocket …

Abstract Poly (methyl methacrylate)(PMMA) is the synthetic polymer of methyl methacrylate
(MMA), which is used in a multitude of everyday applications, can also be used as a solid …

High combustion efficiency is a critical attribute of a successful rocket engine. Reported
combustion efficiency results from ground tests of single port hybrid rocket engines show …
