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 to the s ...

NK-33
The NK-33 and NK-43 are rocket engines designed and built in the late 1960s and early 1970s by the Kuznetsov Design Bureau. The NK designation is derived from the initials of chief designer Nikolay Kuznetsov. The NK-33 was among the most powerful LOX/RP-1 rocket engines when it was built, with a high specific impulse and low structural mass. They were intended for the ill-fated Soviet N1F moon rocket, which was an upgraded version of the N1. The NK-33A rocket engine is now used on the first stage of the Soyuz-2-1v launch vehicle. When the supply of the NK-33 engines are exhausted, Russia will supply the new RD-193 rocket engine. It used to be the first stage engines of the Antares 100 rocket series, although those engines are rebranded the AJ-26 and the newer Antares 200 and Antares 200+ rocket series uses the RD-181 for the first stage engines, which is a modified RD-191, but shares some properties like a single combustion chamber unlike the two combustion chambers used in the ...

RD-0110R
The RD-0110R ( GRAU Index 14D24) is a rocket engine burning kerosene in liquid oxygen in a gas generator combustion cycle. It has four nozzles that can gimbal up to 45 degrees in a single axis and is used as the vernier thruster on the Soyuz-2-1v first stage. It also has heat exchangers that heat oxygen and helium to pressurize the LO2 and RG-1 tanks of the Soyuz-2.1v first stage, respectively. The oxygen is supplied from the same LO2 tank in liquid form, while the helium is supplied from separate high pressure bottles (known as the T tank). The engine's development started in 2010 and it is a heavily modified version of the RD-0110. The main areas of work were shortening the nozzles to optimize them for the atmospheric part of the flight (the RD-0110 is a vacuum optimized engine), propellant piping, heat exchangers and the gimballing system, which was developed by TsSKB Progress. The RD-0110R engine is produced at the Voronezh Mechanical Plant. See also *Soyuz-2-1v - The firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz-2
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 Cosm ...

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 nex ...

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 decided that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GRAU Index
The Main Missile and Artillery Directorate of the Ministry of Defense of the Russian Federation (), commonly referred to by its transliterated Russian acronym GRAU (), is a department of the Russian Ministry of Defense. It is subordinate to the Chief of Armament and Munition of the Russian Armed Forces, a vice-minister of defense. The organization dates back to 1862 when it was established under the name Главное артиллерийское управление (ГАУ – GAU). The "R" from "rockets" was added to the title in 1960. In particular, the GRAU is responsible for assigning GRAU indices to Russian army munitions and equipment. Arsenals of the GRAU, according to Kommersant-Vlast in 2005, include the 60th at Kaluga, the 55th at Rzhev, the 75th at Serpukhov south of Moscow, (all three in the Moscow Military District) and the 80th at Gagarskiy, the 116th at Krasno-Oktyabrskiy and the 5th, all in the Volga–Urals Military District.Kommersant-Vlast, Vys Rossi ...

R-7 (rocket Family)
The R-7 family of rockets (russian: Р-7) is a series of rockets, derived from the Soviet R-7 Semyorka, the world's first ICBM. More R-7 rockets have been launched than any other family of large rockets. When Soviet nuclear warheads became lighter, the R-7 turned out to be impractical as a ballistic missile, and there were no other heavy payloads with a military application. However, long-term development has made the rockets useful in the Soviet, and later, Russian space programmes. Their purpose shifted primarily to launching satellites, probes, manned and unmanned spacecraft, and other non-threatening payloads. The R-7 family consists of both missiles and orbital carrier rockets. Derivatives include the Vostok, Voskhod and Soyuz rockets, which as of 2022 have been used for all Soviet, and later Russian human spaceflights. The type has a unique configuration where four break-away liquid-fueled engines surround a central core. The core acts as, in effect, a "second stage" af ...

Plesetsk Cosmodrome
Plesetsk Cosmodrome ( rus, Космодром «Плесецк», r=Kosmodrom "Plesetsk", p=kəsmɐˈdrom plʲɪˈsʲet͡sk) is a Russian spaceport located in Mirny, Arkhangelsk Oblast, about 800 km north of Moscow and approximately 200 km south of Arkhangelsk, the cosmodrome dates to 1957. Originally developed as an ICBM site for the R-7 missile, it also served for numerous satellite launches using the R-7 and other rockets. Its high latitude makes it useful only for certain types of launches, especially the Molniya orbits, so for much of the site's history it functioned as a secondary location, with most orbital launches taking place from Baikonur, in the Kazakh SSR. With the end of the Soviet Union, Baikonur became a foreign territory, and Kazakhstan charged $115 million usage fees annually. Consequently, Plesetsk has seen considerably more activity since the 2000s. Overview Plesetsk () is used especially for military satellites placed into high inclination an ...

RD-170
The RD-170 ( rus, РД-170, Ракетный Двигатель-170, Raketnyy Dvigatel-170) is the world's most powerful and heaviest liquid-fuel rocket engine. It was designed and produced in the Soviet Union by NPO Energomash for use with the Energia launch vehicle. The engine burns kerosene fuel and LOX oxidizer in four combustion chambers, all supplied by one single-shaft, single-turbine turbopump rated at in a staged combustion cycle. Shared turbopump Several Soviet and Russian rocket engines use the approach of clustering small combustion chambers around a single turbine and pump. During the early 1950s, many Soviet engine designers, including Valentin P. Glushko, faced problems of combustion instability while designing bigger thrust chambers. At that time, they solved the problem by using a cluster of smaller thrust chambers. Variants RD-170 The RD-170 engine featured four combustion chambers and was developed for use on the Energia launch vehicle – both the eng ...

N1 (rocket)
The N1/L3 (from , "Carrier Rocket"; Cyrillic: Н1) was a super heavy-lift launch vehicle intended to deliver payloads beyond low Earth orbit. The N1 was the Soviet counterpart to the US Saturn V and was intended to enable crewed travel to the Moon and beyond, with studies beginning as early as 1959. Its first stage, Block A, remains the most powerful rocket stage ever flown. However, all four first stages flown failed mid-flight because a lack of static test firings meant that plumbing issues and other adverse characteristics with the large cluster of thirty engines and its complex fuel and oxidizer feeder system were not revealed earlier in development. The N1-L3 version was designed to compete with the United States Apollo program to land a person on the Moon, using a similar lunar orbit rendezvous method. The basic N1 launch vehicle had three stages, which were to carry the L3 lunar payload into low Earth orbit with two cosmonauts. The L3 contained one stage for trans-lun ...
