Making Progress Towards «Green» Propellants

Propellants, Explosives, Pyrotechnics, 2018
AbstractStabilisers are used in propellants to prevent the various effects such as oxidation, chain scission, energy loss and uncontrolled heat generation that are caused by homolytic and heterolytic cleavage of the weakest Nitrogen‐Oxygen bond of the nitrate ester functional group.

Selection and Characterization of Green Propellants for Micro-Resistojets

Journal of Heat Transfer, 2017
The number of launches of nano- and pico-satellites has significantly increased over the past decade. Miniaturized subsystems, such as micropropulsion, for these classes of spacecraft are rapidly evolving and, in particular, micro-resistojets have shown great potential of applicability.

Green Propellants

open access: yes, 2018
Friendly or green compositions are being sought in many kinds of applications, such as fertilization, building materials, energy generation, and so on. Thus, this classification (green) can be established after the subjection of the compound to a thorough toxicity study.

Challenges and Opportunities of Green Propellants and Electric Pump Feeding for Future European Kick Stages

open access: yesAerotecnica Missili & Spazio, 2022
This paper analyses the synergy between two innovative technologies: green propellants and electric pump feeding, for a 500 N engine thrust range. The novel approach is then compared to the legacy confguration, i.e., an MMH/NTO pressure fed system ...
