Bundesarchiv RH8II Bild-B0786-42 BSM, Peenemünde, Plakat Auf Rakete
The German Federal Archives or Bundesarchiv (BArch) (german: Bundesarchiv) 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 (Germany), 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 i ...

Kármán Line
The Kármán line (or von Kármán line ) is an attempt to define a boundary between Earth's atmosphere and outer space, and offers a specific definition set by the Fédération aéronautique internationale (FAI), an international record-keeping body for aeronautics. Defining the edge of space is important for legal and regulatory purposes since aircraft and spacecraft fall under different jurisdictions and are subject to different treaties. International law does not define the edge of space, or the limit of national airspace. The FAI defines the Kármán line as space beginning above Earth's mean sea level. This number is well above the altitude reachable by a conventional airplane and is roughly where satellites, even on very eccentric trajectories, will decay before completing a single orbit. While experts disagree on exactly where the atmosphere ends and space begins, most regulatory agencies (including the United Nations) accept the FAI Kármán line definition or someth ...

Bumper (rocket)
The RTV-G-4 Bumper was a sounding rocket built by the United States. A combination of the German V-2 rocket and the WAC Corporal sounding rocket, it was used to study problems pertaining to two-stage high-speed rockets. The Bumper program launched eight rockets between May 13, 1948, to July 29, 1950. The first six flights were conducted at the White Sands Missile Range; the seventh launch, Bumper 8 on July 24, 1950, was the first rocket launched from Cape Canaveral. Bumper program Background The Bumper program to produce and launch a two-stage combination of the V-2 and WAC Corporal rockets was conceived in July 1946 by Colonel Holger N. Toftoy. Both the WAC Corporal and the V-2 had been extensively tested at White Sands Proving Grounds, the WAC Corporal's launch series occurring in late 1945/early 1946 and the V-2 launches beginning March 15, 1946. Bumper was started on June 20, 1947, to: * Investigate launching techniques for a two-stage missile and separation of t ...

V-2 No
IC power-supply pins denote a voltage and current supply terminals in electric, electronics engineering, and in Integrated circuit design. Integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed. These are known as the power-supply pins. However, the labeling of the pins varies by IC family and manufacturer. The double subscript notation usually corresponds to a first letter in a given IC family (transistors) notation of the terminals (e.g. VDD supply for a drain terminal in FETs etc.). The simplest labels are V+ and V−, but internal design and historical traditions have led to a variety of other labels being used. V+ and V− may also refer to the non-inverting (+) and inverting (−) voltage inputs of ICs like op amps. For power supplies, sometimes one of the supply rails is referred to as ground (abbreviated "GND") positive and negative voltages are relative to the ground. In digital electronics, negat ...

V-2 Rocket
The V-2 (german: Vergeltungswaffe 2, lit=Retaliation Weapon 2), with the technical name ''Aggregat 4'' (A-4), was the world’s first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research into military use of long-range rockets began when the graduate studies of Wernher von Braun attracted the attention of the Wehrmacht. A series of prototypes culminated in the A-4, which went to war as the . Beginning in September 1944, over 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from r ...

Kilometre
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre ...

Operation Backfire (WWII)
Operation Backfire was a military scientific operation during and after the Second World War that was performed mainly by British staff. 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. For their part, a number of operations were set by the British, with the Fedden Mission and Operation Surgeon. With the consent of U.S. General Dwight D. Eisenhower, the operation was orchestrated by Major Robert Staver from the Rocket Section of the Research and Development branch of the Ordnance Office that was tasked in directing the effort to find and interrogate the German rocket specialists who had built the V-2. Since April 30 he had been in the Nordhausen area searching the smaller laboratories for V-2 technicians. Auxiliary Territorial Service (ATS) J ...

Ruhrstahl X-4
The Ruhrstahl Ru 344 X-4 or Ruhrstahl-Kramer RK 344 was a wire-guided air-to-air missile designed by Germany during World War II. The X-4 did not see operational service and thus was not proven in combat but inspired considerable post-war work around the world, and was the basis for the development of several ground-launched anti-tank missiles, including the Malkara. History During 1943, the RAF's Bomber Command and the US Air Force mounted a series of heavy raids against Germany. Despite heavy bomber losses, these prompted ''Luftwaffe'' research into considerably more powerful anti-bomber weaponry in order to reduce the cost in lost fighter aircraft and aircrew. A massive development effort resulted in a number of heavy-calibre autocannon designs, air-to-air rockets, SAMs, and the X-4. Work on the X-4 began in June 1943, by Dr Max Kramer at . The idea was to build a missile with enough range to allow it to be fired from outside the range of the bombers' guns (what is now ca ...

Walter Dornberger
Major-General Dr. Walter Robert Dornberger (6 September 1895 – 26 June 1980) was a German Army artillery officer whose career spanned World War I and World War II. He was a leader of Nazi Germany's V-2 rocket programme and other projects at the Peenemünde Army Research Centre. Dornberger was born in Gießen and enlisted in 1914. In October 1918, as an artillery lieutenant Dornberger was captured by United States Marines and spent two years in a French prisoner of war camp, mostly in solitary confinement because of repeated escape attempts. In the late 1920s, Dornberger completed an engineering course with distinction at the Berlin Technical Institute, and in the Spring of 1930,Dornberger's detailed account of the V2 project was one of the first to be published by a major participant. Dornberger graduated after five years with an MS degree in mechanical engineering from the '' Technische Hochschule Charlottenburg'' in Berlin. In 1935, Dornberger received an honorary doc ...

Hermann Göring
Hermann Wilhelm Göring (or Goering; ; 12 January 1893 – 15 October 1946) was a German politician, military leader and convicted war criminal. He was one of the most powerful figures in the Nazi Party, which ruled Germany from 1933 to 1945. A veteran World War I fighter pilot ace, Göring was a recipient of the ("The Blue Max"). He was the last commander of ''Jagdgeschwader'' 1 (Jasta 1), the fighter wing once led by Manfred von Richthofen. An early member of the Nazi Party, Göring was among those wounded in Adolf Hitler's failed Beer Hall Putsch in 1923. While receiving treatment for his injuries, he developed an addiction to morphine which persisted until the last year of his life. After Hitler became Chancellor of Germany in 1933, Göring was named as minister without portfolio in the new government. One of his first acts as a cabinet minister was to oversee the creation of the Gestapo, which he ceded to Heinrich Himmler in 1934. Following the establishment of th ...

MW 18014
MW 18014 was a German A-4 test rocket launched on 20 June 1944, at the Peenemünde Army Research Center in Peenemünde. It was the first man-made object to reach outer space, attaining an apogee of 176 kilometers (109.3 miles), which is well above the Kármán line. It was a vertical test launch. Although the rocket reached space, it did not reach orbital velocity, and therefore returned to Earth in an impact, becoming the first sub-orbital spaceflight. Background Early A-4 rockets, despite being able to reach altitudes of 90 km, had suffered from multiple reliability issues. For example, a design fault in the forward part of the outer hull caused it to regularly fail mid-flight, resulting in the failure of up to 70% of test launches. On one occasion, an A-4 rocket suffering from pogo oscillations during ascent veered 90 degrees off course then spiralled back down to its launch pit, killing four launch troops on site. The Peenemünde rocket team made a number of improv ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
