SOYUZ-2 Launch Vehicle

“Soyuz-2” launch vehicle is a new launch vehicle. It will enable to replace “Soyuz-U”, “Soyuz-FG” launch vehicles with one launch vehicle in the future.

“Soyuz-2” launch vehicle with “Fregat” kick stage will enable to launch spacecrafts to various orbits: low, medium, high elliptical, sun-synchronous, GTO and GSO.

First testing launch of “Soyuz-2-1A” launch vehicle successfully started on November 8, 2004 with the launch from Plesetsk launch site. On October 19, 2006 the first commercial “Soyuz-2-1A” launch vehicle with European meteorological satellite “Metop” was launched.

At present flight tests of “Soyuz-2-1A” launch vehicle have been finished and preparations for its serial production are made.

Flight tests of “Soyuz-2-1B” launch vehicle started on December 27, 2006 with the launch of French research spacecraft “Corot” from Baikonur launch site.

“Soyuz-2” launch vehicle was developed on the basis of “Soyuz” launch vehicle in two phases (phases 1A and 1B).

Modification phase of “Soyuz-2-1A” launch vehicle:

· injectors with improved mixing characteristics are used in engines of the 1-2 stages;

· a new control system, unified for three stages, was developed on the basis of highly efficient digital computer;

· a new digital radio-telemetry system is used;

· the 3 stage unit structure is maximally unified both for modification phase 1A and modification phase 1B.

Modification phase of “Soyuz-2-1B” launch vehicle:

· in addition to improvements of modification phase 1A new engine with greater power capabilities is used in the 3 stage unit.

It enabled to increase orbiting accuracy, stability and controllability of launch vehicle and to use assembly-and-protection module with Nose Fairing of 4.11 m diameter and 11.43 m length.
