TheSoyuz-2.1v(Russian:Союз 2.1в,Union 2.1v),GRAU index14A15,[1]known earlier in development as theSoyuz-1(Russian:Союз 1,Union 1), is a Russianexpendablelaunch vehicle.It is a heavily modified derivative of theSoyuz-2.1b,and is a member of theR-7 familyof rockets. It is built byTsSKB Progress,atSamarain Russia. Launches are conducted from existing facilities at thePlesetsk Cosmodromein Northwest Russia, with pads also available at theBaikonur CosmodromeinKazakhstan,[2]and new facilities at theVostochny Cosmodromein Eastern Russia.[3]
Vehicle[edit]
The Soyuz-2.1v represents a major departure from earlierSoyuzrockets. Unlike the Soyuz-2.1b upon which it is based, it does away with the four boosters used on all otherR-7vehicles. The first stage of the Soyuz-2.1v is based on the Soyuz-2 second stage, with a single-chamberNK-33engine replacing the four-chamberRD-108along with structural modifications. Since the NK-33 is fixed, the stage is also equipped with fourRD-0110Rengines for thrust vector control. The RD-0110R engines add 230.5 kN (51,800 lbf) thrust and heats the pressurization gases.[4]
The NK-33 engines were built in the 1970s for the cancelled SovietN1Moon rocket. These surplus engines offer increased performance over the RD-107; however, only a limited number of engines are available. Once the supply is exhausted, the NK-33 will be replaced by theRD-193.In April 2013, it was announced that the RD-193 engine had completed testing. The RD-193 is a lighter and shorter engine based on theAngara'sRD-191,which is itself a derivative of theZenit'sRD-170.[5]
The second stage of the Soyuz-2.1v is the same as the third stage of the Soyuz-2.1b;[6]powered by anRD-0124engine. Most missions will use aVolgaupper stage to transfer the payload from an initial parking orbit to its final destination. The Volga is derived from the propulsion system of theYantarreconnaissance satellite,and was developed as a lighter and cheaper alternative to theFregat.
The Soyuz-2.1v was designed as a light-class carrier rocket, and has a payload capacity of 2,850 kg (6,280 lb) to a 200 km (120 mi) circularlow Earth orbitwith aninclinationof 51.8° from Baikonur, and 2,800 kg (6,200 lb) to a 200 kilometre orbit at 62.8° from Plesetsk.[2][7]
