Group For The Study Of Reactive Motion
The Moscow-based Group for the Study of Reactive Motion (also known as the ''Group for the Investigation of Reactive Engines and Reactive Flight'' or ''Jet Propulsion Study Group''; ), abbreviated as GIRD (), was a Soviet research bureau founded in 1931 to study various aspects of rocketry. GIRD launched the first Soviet Liquid-propellant rocket, liquid propellant rocket in August 1933. In November 1933 it was incorporated into the Reactive Scientific Research Institute (, , РНИИ, RNII). History The inspiration for establishing the organisation came from Friedrich Zander, Fredrich Tsander, a scientist, inventor, and romantic who dreamed of space travel. Tsander had begun to consider rocket-powered interplanetary flight as early as 1907 and was one of the founding members of the Society for the Study of Interplanetary Communication in 1924. In September 1931 Tsander formed the Moscow-based 'Group for the Study of Reactive Motion', better known by its Russian acronym “GIRD” ...

Austria
Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine Federal states of Austria, states, of which the capital Vienna is the List of largest cities in Austria, most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has Austrians, a population of around 9 million. The area of today's Austria has been inhabited since at least the Paleolithic, Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Roman Empire, Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Western Roman Empire, Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

Eugen Sänger
Eugen Sänger (22 September 1905 – 10 February 1964) was an Austrian aerospace engineer best known for his contributions to lifting body and ramjet technology. Early career Sänger was born in the former mining town of Preßnitz (Přísečnice), near Komotau in Bohemia, part of the Austro-Hungarian Empire at that time . He studied civil engineering at the Technical Universities of Graz and Vienna. As a student, he came in contact with Hermann Oberth's book '' Die Rakete zu den Planetenräumen'' ("By Rocket into Planetary Space"), which inspired him to change from studying civil engineering to aeronautics. He also joined Germany's amateur rocket movement, the '' Verein für Raumschiffahrt'' (VfR – "Society for Space Travel") which was centered on Oberth. In 1932 Sänger became a member of the SS and was also a member of the NSDAP. Sänger made rocket-powered flight the subject of his thesis, but it was rejected by the university as too fanciful. Sänger was allowed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regenerative Cooling (rocket)
In rocket engine design, regenerative cooling is a configuration in which some or all of the propellant is passed through tubes, channels, or in a jacket around the combustion chamber or nozzle to cool the engine. This is effective because the propellants are often cryogenic. The heated propellant is then fed into a special gas-generator or injected directly into the main combustion chamber. History In 1857 Carl Wilhelm Siemens introduced the concept of regenerative cooling. On 10 May 1898, James Dewar used regenerative cooling to become the first to statically liquefy hydrogen. The concept of regenerative cooling was also mentioned in 1903 in an article by Konstantin Tsiolkovsky. Robert Goddard built the first regeneratively cooled engine in 1923, but rejected the scheme as too complex. A regeneratively cooled engine was built by the Italian researcher, Gaetano Arturo Crocco in 1930. The first Soviet engines to employ the technique were Fridrikh Tsander's OR-2 tested i ...

Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

Nitric Acid
Nitric acid is an inorganic compound with the formula . It is a highly corrosive mineral acid. The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into nitrogen oxide, oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% , it is referred to as ''fuming nitric acid''. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%. Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as synthetic dyes and medicines (e.g. metronidazole). Nitric acid is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valentin Glushko
Valentin Petrovich Glushko (; ; born 2 September 1908 – 10 January 1989) was a Soviet engineer who was program manager of the Soviet space program from 1974 until 1989. Glushko served as a main designer of rocket engines in the Soviet program during the heights of the Space Race between United States and the Soviet Union, and was the proponent of cybernetics within the space program.

Hybrid-propellant Rocket
A hybrid-propellant rocket is a rocket with a rocket motor that uses rocket propellants in two different phases: one solid and the other either gas or liquid. The hybrid rocket concept can be traced back to the early 1930s. Hybrid rockets avoid some of the disadvantages of solid rockets like the dangers of propellant handling, while also avoiding some disadvantages of liquid rockets like their mechanical complexity. Because it is difficult for the fuel and oxidizer to be mixed intimately (being different states of matter), hybrid rockets tend to fail more benignly than liquids or solids. Like liquid rocket engines, hybrid rocket motors can be shut down easily and the thrust is throttleable. The theoretical specific impulse (I_) performance of hybrids is generally higher than solid motors and lower than liquid engines. I_ as high as 400 s has been measured in a hybrid rocket using metalized fuels. Hybrid systems are more complex than solid ones, but they avoid significant ...
