Seliger Forschungs- Und Entwicklungsgesellschaft MbH
The Berthold Seliger Forschungs- und Entwicklungsgesellschaft mbH (BSFEGmbH) was a company founded by West German rocket technical designer Berthold Seliger in 1961. Seliger was a former assistant theoretician professor Dr. Eugen Sänger. The company developed and built prototypes of sounding rockets and launched them near Cuxhaven. The BSFEGmbH cooperated strongly with the Hermann-Oberth-Gesellschaft, of which Berthold Seliger was a member. The first rocket developed by the BSFEGmbH was an improved version of the Kumulus, which was first launched on 19 November 1962 and reached a height of 50 kilometres. On 7 February 1963 the BSFEGmbH launched a two-stage rocket with a maximum height of 80 kilometres and, on 2 May 1963, they launched a three-stage rocket with a maximum flight height of more than 100 kilometres. The latter rocket may have attained the highest flight altitude of all rockets built in post-war Germany. The signals from all these rockets were also received at the obs ...

West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The FRG's provisional capital was the city of Bonn, and the Cold War era country is retrospectively designated as the Bonn Republic. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, at that time part of the Austro-Hungarian Empire. 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. In 1928 and 1929 the Opel RAK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

Rocket Experiments In The Area Of Cuxhaven
Between 1933 and 1964 numerous rocket experiments were carried out in the area of Cuxhaven, Germany. 1930s and 1940s *In April 1933 Gerhard Zucker launched a mail rocket, which was to fly from Duhnen to the island of Neuwerk, but which fell to Earth after flying a few meters. *During World War II some test flights of Fi-103 (V1) rockets were flown from the military camp of Altenwalde. In 1945, Kurt Debus was ordered to install a launch pad for testing A4-rockets in the area of Cuxhaven, as a replacement for Stand VII in Peenemünde; however, the project could not be completed due to the military situation towards the end of the war. Nevertheless, in October 1945, these works supplied a basis for " Operation Backfire", a demonstration of three A4-rocket launches to military representatives of the Allied Occupation Forces. One launch pad and two concrete shelters were built for "Operation Backfire", near the road between Arensch and Sahlenburg, where some remnants still exist tod ...

Cuxhaven
Cuxhaven (; ) is an independent town and seat of the Cuxhaven district, in Lower Saxony, Germany. The town includes the northernmost point of Lower Saxony. It is situated on the shore of the North Sea at the mouth of the Elbe River. Cuxhaven has a footprint of (east–west) by (north–south). Its town quarters Duhnen, Döse and Sahlenburg are especially popular vacation spots on the North Sea and home to about 52,000 residents. Cuxhaven is home to an important fisherman's wharf and ship registration point for Hamburg as well as the Kiel Canal until 2008. Tourism is also of great importance. The city and its precursor Ritzebüttel belonged to Hamburg from the 13th century until 1937. The island of Neuwerk, a Hamburg dependency, is located just northwest of Cuxhaven in the North Sea. The city's symbol, known as the Kugelbake, is a beacon once used as a lighthouse; the wooden landmark on the mouth of the Elbe marks the boundary between the river and the North Sea and also adorns t ...

Multistage Rocket
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final speed and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subseq ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

Gerhard Zucker
Gerhard Zucker (1908–1985) was a German businessman and rocket engineer. Biography Born in Hasselfelde, he first came to public notice in 1931, when he began to work on the problem of transporting mail by rocket. In 1933 he performed several experiments in the Harz and at Cuxhaven. In 1934, he emigrated to the UK, where he attempted to interest the British government in his rocket. After a failed rocket demonstration for officials of the British Royal Mail on 31 July 1934, he was deported to Germany, where he was arrested on suspicion of cooperating with the British. During World War II he served in the Luftwaffe. After World War II, he moved across the border to West Germany, to the part of the Harz in Lower Saxony, where he became a furniture dealer. He continued his rocket experiments until, at a rocket demonstration on 7 May 1964 on the Hasselkopf Mountain near Braunlage, an accident occurred which killed three people. This accident led to a ban on civilian rocket resea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
