From Khrunichev Press Release

MOSCOW, Dec. 12, 2007 – Tests have been performed successfully on the first-stage propulsion system for the Angara launch vehicle configured with a flight hydraulic system and steering actuators.

Khrunichev Space Center is developing the Angara launch vehicle family, a new generation of environmentally clean vehicles, based on a core booster module with liquid oxygen/kerosene propulsion.  NPO Energomash is developing the state-of-the art single-chamber RD-191 engine for Angara’s first stage.

During the tests, conducted at the Energomash Glushko facility, engineers tested the steering drive and plumbing in near-flight conditions. The next propulsion system test is scheduled in about a week and will include sine tests of the steering actuators.

Angara flight tests are scheduled for 2011.  By that time standard systems, including launch pads, will be in place for the entire family of Angara boosters. The Russian Federation government signed a decree on Aug. 26, 1995, to create the Angara rocket system. Implementation of the Angara project will enable Russia to launch all types of spacecraft from its own territory and secure independent access to space. This will make Angara all the more indispensable for Russia’s space programs.

Angara will have the capability to deliver payloads to any required altitude and inclination. This will make it possible for Russia to address a broad spectrum of defense and security tasks and, over time, ensure competitiveness in the international market for launch services.

The RD-191 engine is being developed most expeditiously and in sync with performance requirements. Progress is closely monitored by an interagency coordinating group. The group noted that the tests are proving the validity of technical solutions that have been taken in the process of development efforts.  The program is on track to deliver engines for firing tests on schedule, and the group’s consensus is that RD-191 developmental tests will be completed in accord with the Angara master schedule approved by Roskosmos and the Ministry of Defense.
