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 Perspectives for Future Missions

44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2008
Many upper stages and spacecrafts use MMH / NTO for the propulsive manoeuvres. For low and medium delta V operations, a low cost space storable propellant couple could be selected e.g. N2O / propane or propylene. LOX / light hydrocarbon combinations offer superior Isp and are well suited for higher delta V requirements like planetary orbit insertion or
