Shtil (R-29RM)

Makeev State Rocket Center * Babakin Science and Research Center

The Shtil is an ballistic missile, designated the R-29RM or RSM-54. It is a two-stage liquid fueled missile, capable of deploying small spacecraft in LEO. The Shtil-1 uses the warhead fairing to hold the spacecraft, whereas the Shtil-2 (length 18, 4 m) has a larger separating fairing to hold larger spacecraft. Shtil-2 can be launched from ground-based launch table. The Makeyev Design Bureau has proposed an  air-launched version Shtil-3A (lift-off mass 45,6 tons, length 18,7 m, payload for LEO 0,95 ton).
All two stages are liquid-fuelled with storable UDMH/N2O4 propellants. The engines are nestled inside the propellant tanks, rather than below them to save space. Upper and lower bulkheads have unusual shapes to accommodate engines with minimal interstage space.

A number of launch vehicles are being developed now on the basis of technologies and components of RSM-54 missile. These launch vehicles can be launched from the launch tubes of submarines or from the ground-based launch complex located at the northern part of Arkhangelsk region. The family of Shtil light-class LV includes the following launch vehicles: SHTIL -1, SHTIL-2.1, SHTIL-2 and SHTIL-3.
The space rocket system includes:
In July 1998 the Shtil LV has injected two German Tubsat satellites into the near-earth orbit. The launch was made from the Barents Sea by a not dived submarine.
 

In Shtil-2.1 launch vehicle the payload is placed in a special section mounted on the front frame of instrument section. The special section is an assembly consisting of fairing presented by the standard astro-dome of the RSM-54 missile and a coupling section. The coupling section provides for the joining of the payload section and the missile and for the accommodation of the spacecraft.
In Shtil-2R launch vehicle the payload is placed in a special section, which is installed in the LV nose part and comprises nose fairing and adapter used to join the section to the launch vehicle. The newly developed nose fairing protects the payload from dust and moisture and is equipped with a separation and jettison system. The cover of the fairing has hatches to connect the payload with the equipment of ground-based launch complex. For the purpose to increase the Launch Vehicle capacity a small-size upper-stage engine is placed in payload section.
The Shtil-3 launch vehicle is the most powerful missile in the Shtil family. In this case the combat missile was retrofitted as follows:

• new design of the third stage with more fuel stock was developed;

• new instrument section was developed;

• additional injection stage was installed. It passed through a whole cycle of testing;

• new payload section was developed ;

• new on-board measuring complex was developed.

Shtil-K
A new LV Shtil-K can be launched from ground-based launch table. The upper stage Kaplya is intended for Shtil-K launch vehicle. LV Shtil-K is being developed on the base of  RSM-54 missile. It is designed to launch spacecraft into the near-Earth orbit. First two stages developed at the State Rocket Center "Makeyev Design Bureau" and upper composite, which is being under development at Babakin Science and Research Space Center. Upper composite includes the upper stage Kaplya, payload adapter and fairing. Upper stage Kaplya is being developed on the base of elements of the Fregat upper stage.
