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.

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

Making Progress Towards »Green« Propellants – Part II

Propellants, Explosives, Pyrotechnics, 2020
AbstractNitrate‐ester based propellants require stabilisers in order to maintain good chemical stability and to prevent 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. With REACH legislation (1907/2006)
