| Popis: | In 2014 DLR started research activities focused on premixed monopropellants consisting of nitrous oxide and hydrocarbons. Those propellants offer promising characteristics as they are non-toxic, deliver a high Isp consist of components with low cost and could simplify a propulsion system due to self-pressurized operation. Initially DLR chose a mixture of nitrous oxide (N2O) and ethene (C2H4). In the course of the project, a mixture of nitrous oxide and ethane (C2H6) was included to the research activities. The activities are part of DLRs Future Fuels project and divided into five main parts: 1) investigations of the combustion behavior of the propellant in a rocket combustor, 2) testing and developing of flame arresters, 3) development and reduction of reaction mechanisms, 4) numerical simulations of the combustion process and 5) basic miscibility investigations. The emphasis within the project is on the first three tasks, while the last two tasks are used to widen the knowledge about the propellants physical and combustion properties. The following paper will give a short summary of the activities carried out within the projects and focus on selected results regarding premixed propellants. |
