In Russia the work on creation of space rocket solar

Russian specialists offer to use during insertion into orbit booster units with solar thermal rocket engines, the efficiency of which is one and a half to two times higher than the boosters with liquid engines. This is stated in the report of the representatives of the Moscow aviation Institute, which will be presented at the Academic readings on cosmonautics.

"Currently, the capabilities of traditional liquid upper stages close to the limit. To increase their effectiveness requires breakthrough technologies to increase output on orbit mass of a payload. One possible solution to this problem is the use of boosters with solar thermal rocket engines", they say. Proposed by the designers of the engine, in particular, will have to contain the receiver of solar radiation, made in the form of solar panels with photovoltaic cells, which convert incident on the surface of the solar battery of radiant energy into electrical energy.

"Ballistic efficiency boosters with sun motors half to two times higher than liquid funds inter-orbital transfer", — experts say. This will make it possible to use rockets more easy class to launch into geostationary orbit payloads. "Thus, the heavy rocket "proton-M" with the upper stage "breeze-M" can be replaced with a vehicle of the middle class "Soyuz-2" with the "Sunny" upper stage," said the MAI. published
