RD-8
The RD-8 (Russian: and GRAU Index: 11D513) is a Soviet / Ukrainian liquid propellant rocket engine burning LOX and RG-1 (a rocket grade kerosene) in an oxidizer rich staged combustion cycle. It has a four combustion chambers that provide thrust vector control by gimbaling each of the nozzles in a single axis ±33°. It was designed in Dnipropetrovsk by the Yuzhnoye Design Bureau as the vernier thruster of the Zenit (GRAU: 11K77) second stage. As such, it has always been paired with the RD-120 engine for main propulsion. It can only be started once, and as a high altitude engine it has a thrust of and a specific impulse of . It is the first ever steering engine to use the staged combustion cycle, and as such is the basis for a family of planned engines for the Mayak launch vehicle family. The engine itself is built like a hollow cylinder, with a cylindrical space in the center so the RD-120 nozzle can pass through. Derivatives Whilst Yuzhnoye's propulsion experience ...

RD-120
The RD-120 (GRAU Index 11D123) is a liquid upper stage rocket engine burning RG-1 (refined kerosene) and LOX in an oxidizer rich staged combustion cycle with an O/F ratio of 2.6. It is used in the second stage of the Zenit family of launch vehicles. It has a single, fixed combustion chamber and thus on the Zenit it is paired with the RD-8 vernier engine. The engine has been developed from 1976 to 1985 by NPO Energomash with V.P. Radovsky leading the development. It is manufactured by, among others, Yuzhmash in Ukraine. It should not be confused with the RD-0120, which is a discontinued LOX/hydrogen rocket engine that was used in the Soviet Energia launch system. History During the Buran programme initial development of the 11D77 —the launch vehicle later known as Zenit—, KBKhA had been assigned the development of the second stage engine, as they had done for the Proton and Soyuz vehicles. But given the difficulties for NPO Energomash in developing the RD-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RD-861K
The RD-861 is a Soviet liquid propellant rocket engine burning UDMH and nitrogen tetroxide in a gas generator combustion cycle. It has a main combustion chamber, with four vernier nozzles fed by the gas generator output. It can be reignited a single time. History When the Soviet military developed the Fractional Orbital Bombardment System, Yangel's OKB-586 proposed a new version of their R-36 ICBM, called the R-36-ORB ( GRAU Index: 8K69). It incorporated an orbital warhead called OGCh ( GRAU Index: 8F021), for which the RD-854 engine was developed in-house. Since the Outer Space Treaty of 1967 banned nuclear weapons in Earth orbit, but did not ban the launch systems, the Soviet Union proceeded to test their FOBS albeit without placing nuclear warheads in orbit. Versions There are three versions of this engine: * RD-854 ( GRAU Index: 8D612): First developed as the third stage engine for the R-36ORB FOBS. * RD-861 ( GRAU Index: 11D25): Also known as the D-25.

RD-801
The RD-801 ( Russian: ) is a Ukrainian liquid propellant rocket engine burning LOX and Kerosene ( RG-1) in a staged combustion cycle. It has a single combustion chamber that provides thrust vector control by gimbaling of the nozzle in two axis by +/- 6°. It is being designed in Ukraine by Yuzhnoye Design Bureau for the prospective first stage propulsion of the Mayak rocket family.

Mayak (rocket Family)
Mayak is a new family of Ukrainian launch vehicles under development by the Pivdenne, which would be manufactured by Pivdenmash. The family is built in a modular fashion on the basis of a single line of main engines with thrust of roughly for the first stage (RD-801 or RD-810) and for the upper stage (RD-809K derived from RD-8). Engines, control systems and ground equipment are largely derived from components of existing rocket families Zenit and Tsyklon The Tsyklon (Циклон, "Cyclone", also known as Tsiklon), GRAU index 11K67, was a Soviet-designed expendable launch system, primarily used to put Cosmos satellites into low Earth orbit. It is based on the R-36 intercontinental ballistic mi .... The Mayak family is designed to cover small-lift, medium-lift and heavy-lift requirements.

RD-843
The RD-843 is a Ukrainian single nozzle liquid propellant rocket engine burning pressure-fed UDMH and nitrogen tetroxide. It is rated for up to 5 restarts, and can gimbal up to 10 degrees in each direction. It was developed by Yuzhnoye Design Bureau for Avio and is manufactured by Yuzhmash. It uses the RD-869 thrust chamber, the old Soviet ICBM SS-18 Satan final stage engine from which it is evolved, and which was also designed by Yuzhnoye. The RD-843 ground test campaign included 74 tests, 140 ignitions, reaching a total of 8201 s, which is approximately 12 service lives on 4 engines. As of June 2020 it has been successfully used on 14 orbital launches. It is currently used as the main engine of Vega's AVUM upper stage.

RD-855
The RD-855 (GRAU Index 8D68M), also known as the RD-68M, is a four-nozzle liquid-fuel rocket vernier engine, burning N2O4 and UDMH in a gas generator cycle. It was used on the R-36, Tsyklon-2 and Tsyklon-3 first stage as thrust vector control by gimbaling of its nozzle. The engine is distributed through a cylindrical structure that is integrated around the main engine RD-251 module. The structure includes aerodynamic protection for the nozzles and small retro engines to assure the separation of the first stage. The engine was ignited two second before the RD-251 main engine. The engine was serially produced between 1965 and 1992. It was first launched on December 16, 1965 on an R-36 and its last launch was on January 30, 2009 with the last launch of the Tsyklon-3. The production capability was restarted for the Tsyklon-4 but with the apparent cancellation of the program the engine would still be out of production.

Vega (rocket)
Vega ( it, Vettore Europeo di Generazione Avanzata, or french: Vecteur européen de génération avancée, or en, European Vector of Advanced Generation, meaning "Advanced generation European carrier rocket") is an expendable launch system in use by Arianespace jointly developed by the Italian Space Agency (ASI) and the European Space Agency (ESA). Development began in 1998 and the first launch took place from the Centre Spatial Guyanais on 13 February 2012. It is designed to launch small payloads – 300 to 2500 kg satellites for scientific and Earth observation missions to polar and low Earth orbits. The reference Vega mission is a polar orbit bringing a spacecraft of 1500 kg to an altitude of 700 km. The rocket, named after Vega, the brightest star in the constellation Lyra, is a single-body launcher (no strap-on boosters) with three solid rocket stages: the P80 first stage, the Zefiro 23 second stage, and the Zefiro 9 third stage. The upper module is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsyklon-4
The Tsyklon-4, also known as Tsiklon-4 and Cyclone-4, was a Ukrainian carrier rocket which was being developed for commercial satellite launches. Derived from the Tsyklon-3, it had a new third stage, a larger payload fairing, and a modernised flight control system compared to its predecessor. The control system had been developed by JSC Khartron. Specifications Tsyklon-4 was a three-stage-to-orbit expendable launch system, built on the successful Tsyklon-3 rocket and using improved versions of that rocket's first two stages. The new features were mostly in the newly developed third stage: * The third stage has three times the propellant capacity of Tsyklon-3 * The new rocket engine RD-861K with multiple ignition capability (3 to 5 times) * A modern western-like control system capable of precise orbit injections * A new fairing derived from Ariane 4 is under development. It has a diameter of , with controlled temperature and cleanness conditions inside Tsyklon-4 would have i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
