The propulsion system for nanosatellites.

Technology is in the process of development!

 

 

The propulsion system for nanosatellites working on a mixture of distilled water and ethyl alcohol in the ratio of 60 to 40%. The expected combined impact speed is not less than 80 m/s.

 


Description:

The propulsion system for nanosatellites working on a mixture of distilled water and ethyl alcohol in the ratio of 60 to 40 %. The choice of the mixture of water and ethyl alcohol as the working fluid is not accidental. First, water has a low molecular weight, which allows to obtain high velocity of the steam, and the addition of a mixture of alcohol, in turn, allows to prevent freezing of the fuel at low temperatures in earth orbit. Second, the working mixture contains no combustible components, safe and environmentally friendly, does not harm the environment. Thirdly, this liquid working mixture capable of providing high-speed maneuvering nanosatellite.

The principle of operation of the motor installation next. The fuel mixture is pre-heated and evaporated by electric heater. Then heated to a certain temperature pairs of water-alcohol mixture is ejected from the nozzle of Laval . The expected combined impact speed is not less than 80 m/s.

Maximum mass of the fully fueled new motor setup is about 1,55 kg. the Mass of the liquid working medium is 450 grams, which is stored in the tank. Dimensions motor installation small only: 10×10×30 cm., a Similar engine may be equipped with any nanosatellite, which significantly extends the use of space vehicles of nanoglass.
