The researchers of the Inter-University Department of Space Research of Samara University exhibited a model of a drive framework for the moving nanosatellite SamSat-M. The introduction occurred at the IV International Conference “Logical and Technological Experiments on Automatic Space Vehicles and Small Satellites” (SPEXP) in Samara.
The exhibited drive framework for the moving nanosatellite SamSat-M (its measurements are 10x10x30 cm) is electrothermal. The researchers proposed a blend of refined water and ethyl liquor as the working body of the impetus framework. Their decision was clarified by the way that a little atomic mass of water permits acquiring high rates of steam outpouring, and, likewise, a high moving velocity. Also, the expansion of liquor (around 40% of the blend) keeps the working body from solidifying at low temperatures in close Earth circles. As per the engineers, such blend is protected, since it doesn’t contain self-touching off segments, it is non-dangerous and does not cause natural harm.
The researchers likewise accentuate: notwithstanding explaining customary outline errands to upgrade the mass, measurements and vitality qualities of nanosatellites, a standout amongst the most earnest issues is the formation of a solid and generally shoddy framework for propelling such gadgets into the circle. One of the ideal answers for this issue is the dispatch of nanosatellites by “piggyback payload” – on board a huge bearer satellite, or inside the compartments of the officially exhausted phases of transporter rockets. In the meantime for the administrators of room dispatches it is critical to limit any dangers that can influence the yield of the objective load, including the dangers of self-start of any parts inside the passing vehicles.
The designers accentuate that this motor can be furnished with any CubeSat space vehicle. The utilization of the impetus framework significantly extends the capacities of the nanosatellites. As a major aspect of a gathering in space, they can take care of connected issues, which can’t be fathomed by a solitary rocket. In this way, a gathering of nanosatellites can examine geophysical fields, the thermosphere and the ionosphere of the Earth to anticipate catastrophic events, to recognize a space rock risk, and to investigate the condition of rocket in space.
Propulsion System for Nanosatellites
Right now, the researchers of Samara University have built up an entire arrangement of outline documentation and delivered a model of the drive framework on a water-liquor blend. In the college there are trial of the model motor with a specific end goal to distinguish deficiencies for further refinement. In parallel with this, the staff of the Inter-University Department of Space Research outlines an exploratory nanosatellite for completing flight configuration tests.
The most extreme weight of the completely powered creative impetus framework is 1.55 kg. The normal aggregate drive of the speed isn’t under 80 m/s. The fluid working body of the drive framework on a water-liquor blend with an aggregate mass of 450 grams is put away in a tank. Prior to entering the Laval spout, the water-liquor blend is dissipated with an electric warmer, the subsequent gas (steam) is warmed to the required temperature by a similar radiator. Since it is important to direct a fast warming of the working body, the engineers offered to enhance the power matrix of the satellite with Maxwell’s ultracapacitors. This will guarantee that the vital high heartbeat control is conveyed to the radiator. This methodology will be utilized on rockets of this class out of the blue.
