Space launch vehicleShtil' (Russian:Штиль -calm (weather)), is a convertedSLBM used for launchingartificial satellites into orbit. It is based on theR-29RM designed byState Rocket Center Makeyev and related to theVolna Launch Vehicle.[1] The Shtil' is a 3-stage launch vehicle that uses liquid propellant. It is the first launch vehicle to successfully launch a payload into orbit from a submarine, although launch from land based structures is possible as well.

Versions

[edit]

Shtil'

[edit]

This is the baseline version of the launch vehicle. The payload is placed in a special capsule in the space head next to the third stage engine nozzle. The missiles used are withdrawn from active service with theRussian Navy and converted to civilian launch vehicles by removing the warheads and antennas. To inject the payload into the right orbit the flight software is adjusted and additional measuring equipment is installed. Launches can be performed fromDelta IV submarines while submerged.

Proposed versions

[edit]

Shtil'-2.1

[edit]

A proposed version under development of the Shtil' launch vehicle features the payload in a special section on top of the space head. This increases the possible volume and weight of the payload inserted into orbit.

Shtil'-2R

[edit]

A further developed version of the launch vehicle features a larger payload section on top of the space head. The additional space is used for larger and heavier payloads and an additional boost engine to propel the payload in higher orbits. The increase in length of the launch vehicle means that it can only be launched from a ground based launching complex.

Shtil'-3

[edit]

The final proposed version of the Shtil' launch vehicle features a redesigned third stage with enlarged propellant tanks. The space head used on previous version is omitted and replaced by a newly designed section for instruments and thepayload adapter. The payload section can, when necessary for the mission, include an additional booster engine.


Performance

[edit]

Because of its mobile launch platform the Shtil' launch vehicle can reach a large number of different inclinations and bothSun-synchronous orbit andlow Earth orbit. The possible payload is determined by the desired mission. On a typical mission to a 200 km circular orbit at an inclination of 79 degrees the Shtil' has a payload of 280 kg. Proposed version have a higher payload capacity of up to 430 kg for the Shtil-3.

Launch history

[edit]
  • On 7 July 1998, the Shtil' launch vehicle placed two payloads in Low Earth Orbit. The GermanTubsat-N and Tubsat-N1 were launched from theDelta-class submarineK-407Novomoskovsk of the Russian Northern Fleet 3rd Flotilla.[2] The launch was made from a firing range in theBarents Sea. The payloads weighing 8 kg and 3 kg respectively were placed in a 400 x 776 km orbit at an inclination of 78.9 degrees. This was the first time satellites were launched from a submarine.
  • On 26 May 2006, the Shtil' launch vehicle inserted theKompas 2 satellite into Low Earth Orbit.[3] The launch was performed from the Barents Sea by the Delta-class submarineK-84Ekaterinburg. The Kompass 2 satellite has a weight of 77 kg and was put in a 500 km high orbit at an inclination of 79.8 degrees.

Cancelled launch

[edit]
  • TheSouth African satelliteSumbandilaSat, an 80-kg microsatellite with a multispectral imager as primary payload, was scheduled for launch from the Sthil' launch vehicle in early 2007.SumbandilaSat was eventually launched into a 500 km low Earth orbit on 17 September 2009 on aSoyuz-2.1b rocket.
