Angara-1.2pp
The flight of Angara-1.2pp (russian: Ангара-1.2 первого пуска; ''Angara-1.2 pervogo puska'' meaning ''Angara-1.2 first launch'') was the maiden flight of Russia's Angara series of rockets. This flight was conducted successfully on 9 July 2014. A unique configuration with parts taken from the Angara-1 and Angara-A5 rockets, the suborbital mission served to flight test each of the new stages developed for the rocket ahead of its operational use. Background The Angara is the first new rocket built by Russia since the end of the Soviet Union, and is intended to replace several older rockets including the Proton-M, Zenit and Rokot, as well as ensure independent Russian access to geosynchronous orbit from Plesetsk. The development of the Angara launch vehicle was first approved in 1992. The Angara-1.2pp rocket consisted of two Universal Rocket Modules (URMs), a URM-1 first stage and a URM-2 second stage. Although it was the first full Angara to fly, three modified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plesetsk Cosmodrome Site 35
Site 35 at the Plesetsk Cosmodrome is a launch complex used by Russia's Angara rocket. The complex has a single launch pad, Site 35/1, which was first used for the maiden flight of the Angara in July 2014. Zenit Site 35 was originally intended to support the Zenit rocket, which the Soviet Union saw as a replacement for the R-7 series. The construction of a Zenit launch complex at Plesetsk was authorised in 1976; however, development did not begin until the completion of Site 45 at the Baikonur Cosmodrome, which was also constructed for Zenit. Construction at Site 35 began in the mid-1980s, but the programme was abandoned following the dissolution of the Soviet Union. Following the cancellation of Zenit launches from Plesetsk, Russia had originally planned to use parts constructed for Site 35 to repair one of the Zenit pads at Baikonur that had been heavily damaged when a rocket lost thrust and fell back into the flame trench seconds after launch. Instead, the parts were eventu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Angara (rocket Family)
The Angara rocket family (Russian: Ангара) is a family of launch vehicles being developed by the Moscow-based Khrunichev State Research and Production Space Center. The launch vehicles are to put between and into low Earth orbit and are intended, along with Soyuz-2 variants, to replace several existing launch vehicles. History After the dissolution of the Soviet Union, many formerly Soviet launch vehicles were built in or required components from companies now located in Ukraine, such as Yuzhnoye Design Bureau, which produced Zenit-2, and Yuzhmash, which produced Dnepr and Tsyklon. Additionally, the Soviet Union's main spaceport, Baikonur Cosmodrome, was located in Kazakhstan, and Russia encountered difficulties negotiating for its use. This led to the decision in 1992 to develop a new entirely Russian launch vehicle, named Angara, to replace the launch vehicles now built outside of the country, and ensure Russian access to space without Baikonur. It was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Rocket Module
Universal Rocket Module (URM) is the name of the modular liquid fuelled first and second stage of the Angara expendable launch system. The first stage and booster variant is referred to as URM-1, while the second stage is referred to as URM-2. The URM-2 is derived from the Soyuz-2 Block I second stage. URM-1 is a unitary structure 2.9 meters in diameter and 25 meters in length that includes an oxidizer tank, a fuel tank (both tanks being coupled by a spacer) and an RD-191 engine burning RP-1 fuel with liquid oxygen producing a thrust of 1.92 MN. URM-1 was first flown in 2014 on the Angara 1.2PP suborbital test flight. Angara can fly with either one URM-1 in the case of Angara 1.2 and Angara 1.2PP, or one URM-1 as a sustainer core with four additional URM-1s as boosters for Angara A5. URM-2 is a modified Block I stage, 3.6 meters in diameter and 6.9 meters in length. It is powered by a single RD-0124A producing 294 kilonewtons, derived from Block I's RD-0124. URM-2 was first ...

RD-0124
The RD-0124 (GRAU Index 14D23) is a rocket engine burning liquid oxygen and kerosene in a staged combustion cycle. RD-0124 engines are used on the Soyuz-2.1b and Soyuz-2-1v. A slight variation of the engine, the RD-0124A, is used on the Angara rocket family URM-2 upper stage. RD-0124 is developed by Chemical Automatics Design Bureau in Voronezh. Design RD-0124 engines use a multi-stage turbopump powered by pre-combustion of the engine propellants in the preburner. The kerosene fuel is used for regenerative cooling of the engine. Vehicle attitude control during ascent is provided by gimbaling the engine in two planes. The propellant tanks are helium-pressurized. Four combustion chambers are fed by a single turbopump system. The engine operates at a high chamber pressure and, for the type of propellants used, achieves a very high specific impulse of nearly 360 seconds in vacuum – a specific impulse that can only be exceeded by hydrolox rockets like the RS-25, and by the next- ...

Kura Test Range
Kura Missile Test Range ( rus, Ракетный полигон Кура́), originally known as ''Kama'', is a Russian intercontinental ballistic missile impact area located in northern Kamchatka Krai in the Russian Far East. It is the destination for ballistic missiles which are test fired from other centers, and was chosen due to its remoteness and distance. It is northeast of the settlement of Klyuchi and the military townlet is called Klyuchi-1, after the nearest settlement. History The range was developed beginning in 1955 and was operational in 1957. The first impact occurred on 21 August 1957, and was followed by 136 impacts through 1964.''SOVIET ANTIBALLISTIC MISSILE ACTIVITY AT KAMCHATKA'', 18 October 1965 (Top Secret, declassified 11 August 2003), Central Intelligence Agency, Washington D.C., 1965.

Barents Sea
The Barents Sea ( , also ; no, Barentshavet, ; russian: Баренцево море, Barentsevo More) is a marginal sea of the Arctic Ocean, located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial waters.World Wildlife Fund, 2008. It was known among Russians in the Middle Ages as the Murman Sea ("Norse Sea"); the current name of the sea is after the historical Dutch navigator Willem Barentsz. The Barents Sea is a rather shallow shelf sea, with an average depth of , and it is an important site for both fishing and hydrocarbon exploration.O. G. Austvik, 2006. It is bordered by the Kola Peninsula to the south, the shelf edge towards the Norwegian Sea to the west, and the archipelagos of Svalbard to the northwest, Franz Josef Land to the northeast and Novaya Zemlya to the east. The islands of Novaya Zemlya, an extension of the northern end of the Ural Mountains, separate the Barents Sea from the Kara Sea. Although pa ...

Soyuz-2-1v
The Soyuz-2.1v (russian: Союз 2.1в, ''Union 2.1v''), GRAU index 14A15, known earlier in development as the Soyuz-1 (russian: Союз 1, ''Union 1''), is a Russian expendable launch vehicle. It was derived from the Soyuz-2.1b, and is a member of the R-7 family of rockets. It is built by TsSKB Progress, at Samara in Russia. Launches are conducted from existing facilities at the Plesetsk Cosmodrome in Northwest Russia, with pads also available at the Baikonur Cosmodrome in Kazakhstan, and new facilities at the Vostochny Cosmodrome in Eastern Russia. Vehicle The Soyuz-2.1v represents a major departure from earlier Soyuz rockets. Unlike the Soyuz-2.1b upon which it is based, it does away with the four boosters used on all other R-7 vehicles. The first stage of the Soyuz-2.1v is a heavily modified derivative of the Soyuz-2 second stage, with a single-chamber NK-33 engine replacing the four-chamber RD-107 used on previous rockets along with structural modifications ...

Soyuz-2 (rocket)
Soyuz-2 (GRAU index 14A14) is a modernized version of the Soviet Soyuz rocket. In its basic form, it is a three-stage launch vehicle for placing payloads into low Earth orbit. Compared to the previous versions of the Soyuz, the first-stage boosters and two core stages feature uprated engines with improved injection systems. Digital flight control and telemetry systems allow the rocket to be launched from a fixed launch platform, whereas the launch platforms for earlier Soyuz rockets had to be rotated as the rocket could not perform a roll to change its heading in flight. Soyuz-2 is often flown with an upper stage, which allows it to lift payloads into higher orbits, such as Molniya and geosynchronous orbits. The upper stage is equipped with independent flight control and telemetry systems from those used in the rest of the rocket. The NPO Lavochkin manufactured Fregat is the most commonly used upper stage. Soyuz-2 rockets were first launched from Site 31 at the Baikonur ...
