Meillerwagen
The ''Meillerwagen'' () was a German World War II trailer used to transport a V-2 rocket from the 'transloading point' of the Technical Troop Area to the launching point, to erect the missile on the ''Brennstand'' (), and to act as the Service tower, service gantry for fuelling and launch preparation. The unofficial 'Meillerwagen' name was often used in official documents and refers to a parts supplier for the trailer, Meiller-Kipper GmbH of Munich, Germany (founded 1850). The Peenemünde Army Research Center designed the ''Meillerwagen'', and the Gollnow & Son company assembled the ''Meillerwagen'' from supplied components. The ''Meillerwagen'' was assembled with Italy, Italian and Russian Forced labour under German rule during World War II, prisoner laborers of the Government bunker (Germany), Lager Rebstock. The ''Meillerwagen'' was vehicle code number 102 of several vehicles in a V-2 launching battery, which included an 8-ton Sd.Kfz. 7#Germany Army, half-track launch control ...

Blockhaus D'Éperlecques
The ''Blockhaus d'Éperlecques'' (, also referred to as "the Watten bunker" or simply "Watten") is a Second World War bunker, now part of a museum, near Saint-Omer in the northern Pas-de-Calais Departments of France, ''département'' of France, and only some 14.4 kilometers (8.9 miles) north-northwest from the more developed La Coupole V-2 launch facility, in the same general area. The bunker, built by Nazi Germany under the codename Kraftwerk Nord West (Powerplant Northwest) between March 1943 and July 1944, was originally intended to be a launching facility for the V-2 (A-4) ballistic missile. It was designed to accommodate over 100 missiles at a time and to launch up to 36 daily. The facility would have incorporated a liquid oxygen factory and a bomb-proof railway station to allow missiles and supplies to be delivered from production facilities in Germany. It was constructed using the labour of thousands of prisoners of war and forcibly conscripted workers used as slave labou ...

List Of Stoffs
During World War II, Germany fielded many aircraft and rockets whose fuels, and oxidizers, were designated (letter)-''Stoff'' (). The following list of stoffs refers to the World War II aerospace meanings if not noted otherwise. Meaning of ''stoff'' The German word ''Stoff'' (plural ''Stoffe''), like the English word ''stuff'', derives from Old French ''estoffe'', however the meanings are somewhat different. Stoff has a fairly broad range of meanings, including "chemical substance" or "matter", "fuel" and "cloth", depending on the context. The German names of the common elements hydrogen, oxygen and nitrogen are ''Wasserstoff'', ''Sauerstoff'' and ''Stickstoff'' ("hydrogen" being a scientific Greek neologism for "constituent of water", "oxygen" for "constituent of acids", "nitrogen" for "constituent of nitre", i.e. Potassium nitrate">saltpeter - although the German root ''stick-'' is derived from ''ersticken'', "to smother, suffocate", referring to its property of not supportin ...

Operation Backfire (WWII)
Operation Backfire was a military scientific operation of Allies of World War II, the Western Allies during and after the World War II, Second World War that was performed mainly by British personnel. The operation was designed to completely evaluate the entire V-2 rocket assembly, interrogate German personnel specialized in all phases of it, and then to test and launch missiles across the North Sea. Background With the end of the war, the Allies scrambled to acquire German technology. Several military operations had been previously mounted by the British to complete this task, including the Fedden Mission and Operation Surgeon. With the consent of U.S. General Dwight D. Eisenhower, Operation Backfire was orchestrated by Major Robert Staver of the Rocket Section of the Research and Development branch of the Ordnance Office, which had been tasked in directing the effort to find and interrogate the German rocket specialists who had built the V-2. Since 30 April 1945, Major Staver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transporter Erector Launcher
A transporter erector launcher (TEL) is a missile vehicle with an integrated tractor unit that can transport, elevate to a firing position and launch one or more rockets or missiles. History Such vehicles exist for both surface-to-air missiles and surface-to-surface missiles. Early on, such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack, since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site. Usually a number of TELs and TELARs are linked to one command post vehicle (CP or CPV). They may use target information from target acquisition, designation and guidance radar (TADAGR or TAR). Transporter erector launcher and radar (TELAR) A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firi ...

Bundesarchiv Bild 141-1875A, Peenemünde, V2 Auf Abschussbahn
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the y ...

Flow Control Valve
A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Operation Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic control valves. The hydraulic actuators respond to changes of pressure or flow and will open or close the valve. Automatic control valves do not require an external power source, meaning that the fluid pressure is enough to open and close them. Flow control valves, a type of automatic control valve, regulate fluid flow by maintaining a predetermined flow rate, independent of variations ...

High Test Peroxide
High-test peroxide (HTP) is a highly concentrated (85 to 98%) solution of hydrogen peroxide, with the remainder consisting predominantly of water. In contact with a catalyst, it decomposes into a high-temperature mixture of steam and oxygen, with no remaining liquid water. It was used as a propellant of HTP rockets and torpedoes, and has been used for high-performance vernier engines. Properties Hydrogen peroxide works best as a propellant in extremely high concentrations (roughly over 70%). Although any concentration of peroxide will generate some hot gas (oxygen plus some steam), at concentrations above approximately 67%, the heat of decomposing hydrogen peroxide becomes large enough to completely vaporize all the liquid at standard pressure. This represents a safety and utilization turning point, since decomposition of any concentration above this amount is capable of transforming the liquid entirely to heated gas (the higher the concentration, the hotter the resulting gas). Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-Stoff
T-Stoff (; 'substance T') was a stabilised high test peroxide used in Nazi Germany, Germany during World War II. T-Stoff was specified to contain 80% (occasionally 85%) hydrogen peroxide (H2O2), remainder water, with traces (<0.1%) of stabilisers. Stabilisers used included 0.0025% phosphoric acid, a mixture of phosphoric acid, trisodium phosphate, sodium phosphate and Oxyquinoline, 8-oxyquinoline, and sodium stannate. Uses The decomposition of T-Stoff into hot steam and oxygen caused by the addition of the catalyst Z-Stoff (an aqueous solution of permanganates) was used to drive the split-tube steam catapults which launched the V-1 flying bomb. Similarly generated steam was used to drive the turbopump in the German V-2 rocket, V2 rocket, and the pumps in several other rocket engines. The turbopump was used to transport fuel and oxidizer liquids under pressure to the rocket engine of the V2. Another of T-Stoff's many uses was to be combined as the oxidizer, ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air in vehicle tires and shock absorbers are commonly used for improved traction and reduced vibration. Compressed air is an important medium for the transfer of energy in industrial processes and is used for power tools such as air hammer (fabrication), air hammers, Jackhammer, drills, power wrench, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater diving, underwater divers. The diver may carry it in a high-pressure diving cylinder, or surface supplied diving, supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethyl Alcohol
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula . It is an alcohol, with its formula also written as , or EtOH, where Et is the pseudoelement symbol for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. As a psychoactive depressant, it is the active ingredient in alcoholic beverages, and the second most consumed drug globally behind caffeine. Ethanol is naturally produced by the fermentation process of sugars by yeasts or via petrochemical processes such as ethylene hydration. Historically it was used as a general anesthetic, and has modern medical applications as an antiseptic, disinfectant, solvent for some medications, and antidote for methanol poisoning and ethylene glycol poisoning. It is used as a chemical solvent and in the synthesis of organic compounds, and as a fuel source for lamps, stoves, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Oxygen
Liquid oxygen, sometimes abbreviated as LOX or LOXygen, is a clear cyan liquid form of dioxygen . It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which is ongoing. Physical properties Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid oxygen. Further, if soaked in liquid oxygen, some materials su ...
