State Central Research Institute of Machine Building (TsNIIMash at Roskosmos) two years is going to release a new space for astronauts jetpacks. They are expected to ensure safe operation of the open space and to help astronauts in an emergency return to the station. Weight Space backpack should not exceed ten kilograms.
The main feature of the knapsack – it’s solar panels, which can be deployed when needed. As explained by the researcher MIPT Ivan Zavyalov, the rate of release of gases through the jet nozzle a conventional jet engine is very limited, while in the electric propulsion new knapsack gas is ionized, ions are accelerated by an electric field – as a result the rate of exhaust gas turns ten times higher than a conventional jet engine. This makes the electric propulsion less energy. Besides this novelty, still has a backpack, and additional engines that, while the front spacesuit, will serve as a brake when docking the ship.
It is expected that the weight of the backpack is a space no more than 10 kilograms. Ideas satchels space for movement in free space were long, even the writers of science fiction. One of the first trial of the Americans was a rocket gun that they had with them. It is a small jet engine-like lady hair.
« In fact, the hair dryer is also possible to fly, though not in the open space, and inside the station. For example, the cosmonaut Yuri Artyuhin inside the station flew a household vacuum cleaner », – says Burdaev.
The man first went into space 50 years ago. March 18, 1965 did cosmonaut Alexei Leonov aboard the “Voskhod-2″. At present, Russian and American astronauts to engage with the station using tethers (wires) with carbines, which are attached to the body of the station. The files alternately cling to elements of construction and fixed, which does not allow astronauts to fly into space.
The need for knapsack overdue, as now people do not come up with more sophisticated machines and robots that can replace human in space. Another important factor is the value of the safe disposal of the astronaut to the station, so it should provide a backpack. Solar panels can move the astronaut by 50-100 meters. The Americans managed to shoot with abandoned satellites most valuable items and then use them on the new moons.
At present, Russia established setting astronaut saver (USC), but it is not used. It does not provide a braking device and recharge from the sun.
How to assure the chief specialist of the Rocket and Space Corporation “Energia”, cosmonaut Yuri Usachev such devices are necessary in a modern space. It fully supports the development of new means of moving in space. “Today the security of Russian cosmonauts provide only halyards and carbines. Of course, these devices need to astronauts, “- emphasizes Usachev.
