Soyuz-2-1vFrom Wikipedia, the free encyclopedia

The Soyuz-2-1v (Russian: Союз 2.1в, Union 2.1v),

GRAU index 14A15,[1] known earlier in development asthe Soyuz-1 (Russian: Союз 1, Union 1), is a Russianexpendable carrier rocket. It was derived from theSoyuz-2.1b, and is a member of the R-7 family ofrockets. It is built by TsSKB Progress, at Samara in theRussian Federation. Launches are conducted fromexisting facilities at the Plesetsk Cosmodrome inNorthwest Russia, with pads also available at the

Baikonur Cosmodrome in Kazakhstan,[2] and newfacilities at the Vostochny Cosmodrome in Eastern

Russia.[3]

Vehicle

The Soyuz-2-1v is a major departure from earlier Soyuzrockets. Unlike the Soyuz-2-1b upon which it is based, itomits the four boosters used on all other R-7 vehicles.The first stage of the Soyuz-2-1v is a heavily modifiedderivative of the Soyuz-2 first stage, with a single-chamber NK-33 engine replacing the four-chamber RD-117 used on previous rockets along with structuralmodifications to the stage and lower tanking.

The NK-33 engine, originally built for the N1 programme,offers increased performance over the RD-117, howevera limited number are available. Once the supply isexhausted, the NK-33 will be replaced by RD-193. InApril 2013, it was announced that the RD-193 engine hadcompleted testing. The RD-193 is a lighter and shorterengine based on the Angara's RD-191, which is itself a

derivative of the Zenit's RD-170.[4]

The second stage of the Soyuz-2-1v is the same as the

third stage of the Soyuz-2-1b;[5] powered by an RD-0124 engine. For most missions a Volga upper stage will

be used to manoeuvre the payload from an initial parkingorbit to its final destination. The Volga is derived from thepropulsion system of the Yantar reconnaissance satellite,and was developed as a lighter and cheaper alternative tothe Fregat.

The Soyuz-2-1v designed as a light-class carrier rocket,and has a payload capacity of 2,850 kilograms (6,300 lb)to a 200-kilometre (120 mi) circular low Earth orbit withan inclination of 56.8° from Baikonur, and 2,800

kilograms (6,200 lb) to a 200 kilometre orbit at 62.8° from Plesetsk.[2]

Maiden flight

In 2009, the maiden flight of the Soyuz-2-1v was announced as being scheduled for 2010, with this later beingdelayed to 2011 and then 2012 by development delays and payload availability. By June 2011 it was scheduledto occur at the end of 2012. During a test firing of a first stage prototype in August 2012, a test stand software

malfunction resulted in damage to the stand and prototype, delaying the static testing programme.[6]

The test was re-attempted in May 2013, and was declared successful despite the burn lasting 52 secondsshorter than had been expected. With this complete, the launch was scheduled for September 2013. It

subsequently slipped to November and then December.[7]

The maiden flight – which made use of a Volga upper stage – carried the Aist 1 microsatellite and a pair ofSKRL-756 calibration spheres. Ahead of the launch, the rocket was rolled out to Site 43/4 at the Plesetsk

Cosmodrome on 18 December 2013 with launch scheduled for 23 December.[7]

The launch was delayed from 23 December by problems found during late testing at the pad. An attempt tolaunch was made on 25 December, however it was scrubbed around ten minutes before the liftoff, which hadbeen scheduled for 14:00 UTC. Despite reports that the launch could not take place before the end of the year,

it was rescheduled for 10:30 UTC on 28 December.[8] A further last-minute delay pushed the liftoff back to

12:30 UTC (16:30 local time), at which time the launch took place successfully.[9] Spacecraft separation

occurred 100 minutes later, at 14:10 UTC.[10]
