RD-0146
The RD-0146 (РД-0146, Ракетный Двигатель-0146, Rocket Engine-0146) is a liquid-fuel cryogenic rocket engine developed by KBKhA Kosberg in Voronezh, Russia. The RD-0146 is the first Russian rocket engine to burn liquid oxygen and liquid hydrogen in the expander cycle, in which turbopumps are driven by waste heat absorbed in the nozzle and combustion chamber. The RD-0146 featured the fastest-spinning turbopump of any serially produced rocket engine: the fuel turbopump spun at over 120,000 rpm.The RD-0146M variant uses liquified natural gas as a fuel instead of hydrogen, while the RD-0146D variant is projected to produce specific impulse (''Isp)'' as high as in a vacuum. The engine has been proposed for use on multiple carrier rockets throughout its history. RD-0146 variants were, at various times, selected to power new upper stages for Proton, Angara, Onega (a development of Soyuz-2), and Rus-M. As of 2022, the RD-0146D is in development for use on the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rus-M
Rus-M (russian: Русь-М) was a proposed launcher design which was intended to become Russia's main launch vehicle for crewed spaceflight after 2018, and an integral part of the Orel spacecraft being developed to replace the Soyuz. Rus-M was being developed by TsSKB-Progress, beginning in 2009. The program was halted in October 2011, restarted in 2012 and finally cancelled in August 2015. History In 2009, Roscomos published the specifications for a Rus-M launch vehicle. Several variants of the Rus-M were later proposed, creating a family of similar launch vehicles. In spring of 2009, TsSKB-Progress won a government contract to develop a new launcher for Russia's human space program. The project was featured in MAKS 2009 Airshow, and preliminary design of the vehicle was expected to be submitted to the Russian space agency Roscosmos by August 2010. Requirements Safety requirements put forward by Roscosmos emphasized that the launcher design is to be extremely reliable; saf ...

KVTK (rocket Stage)
The KVTK (russian: Кислородно-водородный тяжёлого класса, Oxygen/Hydrogen Heavy Class) is a liquid oxygen/hydrogen upper stage for high energy orbits that is currently under development. The KVTK contains an RD-0146D engine and is designed for use on Angara rockets. KVTK would be the first hydrogen-powered upper stage for use on a Russian launch vehicle, although Khrunichev has previously produced a hydrogen-powered upper stage (KVD-1) for the Indian GSLV. KVTK is designed to provide up to five ignitions, allowing for complex orbital maneuvering, and have an on-orbit lifespan of up to nine hours. KVTK would allow an increase in payload to GTO of 20-50% compared to the Angara A5's standard Briz-M upper stage, powered by UDMH and N2O4. History The KVTK was originally studied as an upper stage for the Energia family of rockets, but in 1987 was superseded by the RCS stage (Retro and Corrections Stage), based loosely on the American S-IVB. In 1996, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expander Cycle (rocket)
The expander cycle is a power cycle of a bipropellant rocket engine. In this cycle, the fuel is used to cool the engine's combustion chamber, picking up heat and changing phase. The now heated and gaseous fuel then powers the turbine that drives the engine's fuel and oxidizer pumps before being injected into the combustion chamber and burned. Because of the necessary phase change, the expander cycle is thrust limited by the square–cube law. When a bell-shaped nozzle is scaled, the nozzle surface area with which to heat the fuel increases as the square of the radius, but the volume of fuel to be heated increases as the cube of the radius. Thus beyond approximately 300 kN (70,000 lbf) of thrust, there is no longer enough nozzle area to heat enough fuel to drive the turbines and hence the fuel pumps. Higher thrust levels can be achieved using a bypass expander cycle where a portion of the fuel bypasses the turbine and or thrust chamber cooling passages and goes directly to the ma ...

Cryogenic Rocket Engine
A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel and oxidizer; that is, both its fuel and oxidizer are gases which have been liquefied and are stored at very low temperatures. These highly efficient engines were first flown on the US Atlas-Centaur and were one of the main factors of NASA's success in reaching the Moon by the Saturn V rocket. Rocket engines burning cryogenic propellants remain in use today on high performance upper stages and boosters. Upper stages are numerous. Boosters include ESA's Ariane 5, JAXA's H-II, and the United States Delta IV and Space Launch System. The United States, Russia, Japan, India, France and China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ... are the only countries that have operational cryogenic rocket engines ...

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] |

Gas Generator
A gas generator is a device for generating gas. A gas generator may create gas by a chemical reaction or from a solid or liquid source, when storing a pressurized gas is undesirable or impractical. The term often refers to a device that uses a rocket propellant to generate large quantities of gas. The gas is typically used to drive a turbine rather than to provide thrust as in a rocket engine. Gas generators of this type are used to power turbopumps in rocket engines, in a gas-generator cycle. It is also used by some auxiliary power units to power electric generators and hydraulic pumps. Another common use of the term is in the industrial gases industry, where gas generators are used to produce gaseous chemicals for sale. For example, the chemical oxygen generator, which delivers breathable oxygen at a controlled rate over a prolonged period. During World War II, portable gas generators that converted coke to producer gas were used to power vehicles as a way of alleviat ...
