Development History
On August 26, 1995 the government of Russia adopted a resolution to develop the Angara launcher system.
On December 12, 2007 Krunichev announced that at NPO Energomash, engineers had successfully tested flight hydraulics and steering actuators for the first stage under near-flight conditions.
In cooperation with Salyut Design Bureau, Khrunichev designed a reusable flyback Baikal booster rocket, to serve as a first stage in the Angara family.
On April 14, 2008, Rian news agency reported that the Flight tests of a new-generation Russian space launch vehicle will start in 2010, the director of the Khrunichev State Research and Production Center said on Monday.
On September 5, 2008, the creator of the RD-191 engine, NPO Energomash, reported that the engine has completed full cycle of development and burn tests and is ready for manufacturing and delivery.
On January 10, 2009, the first completed URM was delivered to the proving grounds. Cold and burn tests were planned to be performed in the first half of 2009.
On April 29, 2009 the first series of cold tests has been performed. The URM was filled with nearly 100 tonnes of liquefied oxygen to check functioning of hydraulic and pneumatic pumping systems.
On June 18, 2009, both fuel components were used for tests.
On July 30, 2009, the burn tests of the first URM equipped with RD-151 engine were performed.
On August 25, 2009 South Korea launched its Naro-1 rocket, with URM/RD-151 making up the first stage. With height of 30 m and weight of 140 tonnes Naro-1 is similar to Angara 1.1 configuration. The launch marked the first flight test of the URM, which successfully propelled the rocket to altitude of 196 km, where the first stage separated. However, the fairing on the Korean-built second stage failed to separate, and the satellite did not reach the correct orbit.
On December 5, 2009 Roscosmos announced the completion of engine trials, but that the first test flight of the Angara would be postponed from 2011 to 2012 due to lack of funding. The Khrunichev center has asked the government to allocate an additional 10 billion rubles (about $290 million) over the next three years to finish the development of the rocket.
On January 13, 2010 Vladimir Nesterov, Director-General of Khrunichev, announced that his company had received the required funding, and the first flight test of Angara is now scheduled for 2013. All program tasks in 2010 were completed successfully.
On May 25, 2011 interdepartmental committee (IDC), formed by a joint decision of the Space Forces of the Ministry of Defence and the Federal Space Agency, signed the Act IAC, which stated that the RD-191 engine has successfully completed ground tests stage and is suitable for use in a family of launch vehicles "Angara"
On April 20, 2012 ship Repair Center "Zvezdochka" successfully completed factory testing of the first - class light unit weight 197 tonnes, of the two transport-erector for launching sites "Angara". Equipment is designed for the transportation and installation of missiles light and heavy at the start.
On October 25, completed transcripts tested structural elements of the launch vehicle "Angara". According to the FSUE Khrunichev. 23 October 2012, the PCF "SIC RCP" (p. Remmash) successfully completed tests on transcripts strength structural elements promising launch vehicle (LV) "Angara" (product A5A2S - build number A13) manufacturing FSUE " name Khrunichev. " Purpose of the test build number A13 was to confirm the strength of the accelerator sections III stage of the launch, as well as the design of individual units "Angara" 3A and 5A

Famous quotes containing the words development and/or history:
“A defective voice will always preclude an artist from achieving the complete development of his art, however intelligent he may be.... The voice is an instrument which the artist must learn to use with suppleness and sureness, as if it were a limb.”
—Sarah Bernhardt (1845–1923)
“The thing that struck me forcefully was the feeling of great age about the place. Standing on that old parade ground, which is now a cricket field, I could feel the dead generations crowding me. Here was the oldest settlement of freedmen in the Western world, no doubt. Men who had thrown off the bands of slavery by their own courage and ingenuity. The courage and daring of the Maroons strike like a purple beam across the history of Jamaica.”
—Zora Neale Hurston (1891–1960)
