The global search for green alternatives to the highly toxic monopropellant hydrazine
(N2H4) is still ongoing. Different alternatives for hydrazine with different degrees of maturity …

Across the globe, several green propellants as substitute for the highly toxic hydrazine are
under investigation. A possible alternative are so called nitrous oxide fuel blends. This paper …

This Review examines the gas-phase oxidations of hydrogen and other fuels (ammonia,
hydrazine, hydrocarbons) with nitrous oxide, running as self-ignitions, deflagrations, or …

Unsaturated hydrocarbons are major components of transportation fuels, combustion
intermediates, and unburnt exhaust emissions. Conversely, NOx species are minor species …

Currently, several green propellants are under investigation to replace the toxic and
carcinogenic monopropellant hydrazine (N 2 H 4). Beside alternatives as ammonium …

In 2014 DLR started research activities focused on premixed monopropellants consisting of
nitrous oxide and hydrocarbons. Those propellants offer promising characteristics as they …

Mixtures of hydrocarbons and nitrous oxide are known as green propellants and could
replace the highly toxic hydrazine and hydrazine derivatives as rocket fuel, since they are …

The combustion properties of propellants like ethane/nitrous oxide mixtures that have the
potential to substitute hydrazine or hydrazine/dinitrogen tetroxide in chemical propulsion …

Nitrous oxide and fuel blends propellant as one of the substitutes for highly toxic hydrazine
are under investigation. This study investigated the flame structure and dynamics of …

The present paper gives a comprehensive overview and summary of research and test
activities conducted at the test facility M11 and the physical-chemical lab at DLR in …
