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.

Yuzhnoe Design Bureau
The ''Pivdenne'' Design Office (), located in Dnipro, Ukraine, is a designer of satellites and rockets, and formerly of Soviet intercontinental ballistic missiles (ICBMs), established by Mikhail Yangel. During the Soviet era, the bureau's OKB designation was OKB-586. The company is in close co-operation with the PA Pivdenmash multi-product machine-building company, also situated in Dnipro. Pivdenmash is the main manufacturer of the models developed by Pivdenne Design Office.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vernier Thruster
A vernier thruster is a rocket engine used on a spacecraft or launch vehicle for fine adjustments to the attitude or velocity. Depending on the design of a craft's maneuvering and stability systems, it may simply be a smaller thruster complementing the main propulsion system, or it may complement larger attitude control thrusters, or may be a part of the reaction control system. The name is derived from vernier calipers (named after Pierre Vernier) which have a primary scale for gross measurements, and a secondary scale for fine measurements. Vernier thrusters are used when a heavy spacecraft requires a wide range of different thrust levels for attitude or velocity control, as for maneuvering during docking with other spacecraft. On space vehicles with two sizes of attitude control thrusters, the main ACS (Attitude Control System) thrusters are used for larger movements, while the verniers are reserved for smaller adjustments. Due to their weight and the extra plumbing requi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Rocket Engines Using The Gas-generator Cycle
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to Acceleration, accelerate without using any surrounding Atmosphere of Earth, air. A rocket engine produces thrust by Reaction (physics), reaction to exhaust expelled at high speed. Rocket engines work entirely from rocket propellant, propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with Airbreathing jet engine, airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, Reaction control system, auxiliary reaction engines, gimballed thrust, Reaction wheel, momentum wheels, Thrust vectoring, deflection of ...
