Making Progress Towards «Green» Propellants
Propellants, Explosives, Pyrotechnics, 2018AbstractStabilisers 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, 2008Many 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, 2020AbstractNitrate‐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)

Propeller efficiency options for green ship
Proceedings of 2012 9th International Bhurban Conference on Applied Sciences & Technology (IBCAST), 2012Environmental issues and rising fuel prices necessitate better energy-efficiency in all sectors. Shipping industry is one of the stakeholders in environmental issues. Shipping industry is responsible for 3 % of global CO 2 emissions, 14–15 % of global NO X emissions and 16 % of global SO X emissions.

The propellant storage compartments (propellant tanks) are one of the parts that have undergone noted evolution in the design nature (mainly the shape and the structural properties) as well as the development process. To achieve high system performance for a given propulsion system, inert mass reduction as well as efficient volume utilization can be ...
