The low toxicity hypergolic solid fuels (HSFs) and hydrogen peroxide (H 2 O 2) oxidizer have
been demonstrated as environment-friendly hybrid propellants. In the present study, a new …

Hybrid rocket propulsion can contribute to reduce launch costs by simplifying engine design
and operation. Hypergolic propellants, ie igniting spontaneously and immediately upon …

An experimental study is conducted to measure the ignition delay of ammonia borane doped
paraffin wax with sprays of white fuming nitric acid as oxidizer. The injection pressure and …

The ignition delay and surface-temperature evolution of ammonia-borane-doped paraffin
wax exposed to white fuming nitric acid are measured in oxidizer-drop tests. The ammonia …

Abstract Development of fully green hybrid propulsion systems, in which both the oxidizer
and the fuel are environmentally benign, while having a desirable performance under in …

Hypergolic solid fuels provide rapid and reliable ignition for hybrid rockets, offering
significant advantages over conventional methods. However, a practical experimental …

Hypergolic ignition systems, where combustion is initiated nearly instantaneously upon
contact between the oxidizer and the fuel, can improve the reliability, safety, and simplicity of …

The ignition delay of ammonia-borane-doped sorbitol and paraffin-based fuel pellets
exposed to white fuming nitric acid is measured in oxidizer drop tests. Various mixtures of …

A paraffin-based fuel coupled with a nested helical matrix structure is a low-cost, high-
performing alternative for hybrid rocket engine applications. The mechanical and …

A hypergolic system is a combination of organic fuel and oxidizer that ignites spontaneously
upon contact without any external ignition source. Although their main usage pertains to …
