Rus-M

The Rus -M (Russian Русь - М ) is a currently under development Russian launcher. It is developed by TsSKB -progress and will replace the Soyuz as manned launch vehicle. A new, more powerful rocket is needed for this purpose, as well as the new, larger spacecraft PPTS is to be put into service. In spring 2009 TsSKB -Progress has won the contract for the development of Rus -M and shall submit the preliminary design until August 2010. The Rus -M is in direct competition for direct Soyuz successor Angara. This is quite intentional from a political perspective, as the manned Russian space would only set on a rocket and therefore only one manufacturer otherwise. In October 2011, Vladimir Popovkin gave the head of the Russian Space Agency announced that the development of the Rus -M is set.

Technology

The Rus -M is in its basic version a payload of 23.8 tonnes in a 200 km LEO and 18.8 tons at a manned mission into a 135 to 440 -km orbit bring. These payloads are much higher up than the Soyuz rocket used previously. The rocket consists in the basic version of three boosters and an advanced level. The three booster, one of which forms the central stage are constructed the same. On the middle booster the upper is attached. To drive the rocket is placed on proven technology. Each booster burns in an RD -180 engine RP -1 and liquid oxygen. In this case, of the three engines together in 1016 t thrust generated. The second stage focuses on the high-energy propellant combination of liquid oxygen and liquid hydrogen ( LOX/LH2 ). This is burned in four RD -0146 engines and produces 40 tons thrust.

Versions

On the website of the Russian space rocket further releases will be made in view. More detailed data will not be delivered. The second variant of the Rus - M has a total of five engines in the first stage and to 35 tonnes transported in a 200 km LEO. The third version is in the first stage also five boosters, which were extended. This version is 50 tons in a 200 km LEO transport. When the missile was officially launched in October 2009, also a super heavy version of the missile was announced. This is 130-150 t in a 200 km LEO transport. This version is intended can also be realized with the same components. However, options are discussed for use in all stages of LH2 and LOX or even 3-component fuels ( Triergol ). Detailed information about this release, however, not known.
