Russian scientists created an engine for nano-satellites which works on a water-alcohol mixture
«Scientists at the University have developed a complete set of design documentation and produced a prototype of a propulsion system which works on a water-alcohol mixture for 'SamSat-M', a nanosatellite with maneuvering capability. Tests of the prototype are currently being carried out, at the same time as design of an experimental nanosatellite for flight design tests is made», the press service said.
This development will make it possible to equip nanosatellites with a reliable and inexpensive in-orbit maneuvering system. The scientists suggested using a mixture of distilled water and ethyl alcohol to fuel the propulsion installation. The mixture is evaporated using an electric heater before entering the nozzle, then the resulting steam is heated to the required temperature with the same heater.
