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 im ...

Tsyklon
The Tsyklon (, "Cyclone", also known as Tsiklon), GRAU index 11K67, was a Soviet-designed expendable launch system, primarily used to put Kosmos satellites into low Earth orbit in the late-1960s. It is based on the R-36 intercontinental ballistic missile designed by Mikhail Yangel and made eight launches, with seven successes and one failure. All of its launches were conducted from LC-90 at the Baikonur Cosmodrome. It is sometimes designated Tsyklon-2A, not to be confused with the later Tsyklon-2 rocket. It was introduced in 1967 and was derived from the R-36 ICBM (NATO designation SS-9 Scarp). It was retired in 1969. It made its maiden flight on 27 October 1967. The booster's design was kept secret and no images or film clips of the complete vehicle were released to the public until after the collapse of the Soviet Union, in part because of being used exclusively for military payloads and also because it was derived from an actively serving missile system. After 1991, the pla ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tsyklon-3
The Tsyklon-3, also known as Tsiklon-3 and Cyclone-3 (known as SL-14 by the United States DoD), GRAU index 11K68, was a Soviet, and subsequently Ukrainian orbital carrier rocket. Overview Tsyklon-3 launching a Meteor-3 satellite at left A derivative of the R-36 ICBM, and a member of the Tsyklon family, Tsyklon-3 made its maiden flight on 24 June 1977, and was retired on 30 January 2009. The Ukrainian-built Tsyklon rockets were retired in favour of future all-Russian carrier rockets, such as the Angara, and because they were fuelled by toxic hypergolic propellants. Successor Ukraine was developing a commercial derivative of the Tsyklon-3, the Tsyklon-4. The development of Tsyklon-4 ended in 2015 after Ukraine's development partner Brazil pulled out of the project. Tsyklon-4 never made it to launch pad. Another successor to the Tsyklon rockets, Cyclone-4M (based on Tsyklon-4 designs), is under development as of 2021 for use in the commercial market. Debris 2013 lo ...

Cyclone-4M
The Cyclone-4M is a Ukrainian carrier rocket which is being developed for commercial satellite launches. History The Cyclone-4M is derived from the Tsyklon-4, which started its life as an all-hypergolic three-stage-to-orbit expendable launch vehicle planned for launch from a proposed site at the Alcântara Launch Center in Brazil. However, Brazil backed out of the partnership with Ukraine in 2015, citing concerns over the project budget, the ongoing financial situation in both countries, and the future of the commercial launch market. In March 2017, Canadian company Maritime Launch Services announced plans to begin launching a modified version, the Cyclone-4M, which features a Zenit-derived LOXRP-1 first stage in place of the originally planned R-36 ICBM-based first- and second-stage. In November 2021, Maritime Launch Services CEO Stephen Matier stated that Nanoracks was to be the first client to fly a payload on the Cyclone-4M. Design This new first-stage design would ...

RD-855
The RD-855 (, GRAU index: 8D68M), also known as the RD-68M, is a liquid-fueled rocket engine with four nozzles. As a vernier engine, it provides fine steering adjustments for rockets. It is powered by a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide () oxidizer. This combination is hypergolic, meaning the two substances ignite on contact, eliminating the need for an external ignition source. The RD-855 can orient its chambers within a range of ±42° using hydraulic cylinders. Each chamber on the Tsyklon rockets is protected by an aerodynamic cover, and these covers are equipped with small retro-rockets allowing for separation from the second stage. The RD-855 utilizes the gas generator cycle, in which a portion of the propellant is burned in a pre-burner to produce hot gases that drive the engine's turbopumps, and then the gases are discarded without passing through the main combustion chamber. It played a key role in rockets such ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

RD-856
The RD-856 (, GRAU index: 8D69M), also known as the RD-69M, is a four-nozzle liquid-fuel rocket vernier engine, burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide () oxidizer in a gas generator cycle. It was used on the R-36, Tsyklon-2 and Tsyklon-3 second 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-252 module. The structure includes aerodynamic protection for the nozzles. The engine was started by a pyrotechnic ignitor. 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.

Ariane 4
The Ariane 4 was a European expendable rocket, expendable launch vehicle in the Ariane (rocket family), Ariane family, developed by the (CNES), the Government of France, French space agency, for the European Space Agency (ESA). The manufacturing of the launch vehicle was led by Aérospatiale and it was marketed by Arianespace. Since its first flight on 15 June 1988 until the final flight on 15 February 2003, it attained 113 successful launches out of 116 total launches. In 1982, the Ariane 4 program was approved by ESA. Drawing heavily upon the preceding Ariane 3, it was designed to provide a launcher capable of delivering heavier payloads and at a lower cost per kilogram than the earlier members of the Ariane family. The Ariane 4 was principally an evolution of the existing technologies used, as opposed to being revolutionary in its design ethos; this approach quickly gained the backing of most ESA members, who funded and participated in its development and operation.

Zenit (rocket Family)
Zenit (, ; meaning ''Zenith'') was a family of space launch vehicles designed by the Yuzhnoye Design Bureau in Dnipro, Ukraine, which was then part of the Soviet Union. Zenit was originally built in the 1980s for two purposes: as a liquid rocket booster for the Energia (rocket), Energia rocket and, equipped with a second stage, as a stand-alone middle-weight launcher with a payload greater than the 7 tonnes of the Soyuz (rocket), Soyuz but smaller than the 20 tonnes payload of the Proton (rocket family), Proton. The last rocket family developed in the USSR, the Zenit was intended as an eventual replacement for the dated Soyuz and Proton families, and it would employ propellants which were safer and less toxic than the Proton's nitrogen tetroxide/UDMH mix. Zenit was planned to take over crewed spaceship launches from Soyuz, but these plans were abandoned after the dissolution of the Soviet Union in 1991. Many of components of the Zenit rockets were produced in Russia. The Ukraini ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
