Seliger Rocket
Seliger Rocket is the designation for the sounding rockets of the Berthold Seliger Forschungs- und Entwicklungsgesellschaft mbH. They were # A single-stage rocket with a length of 3.4 metres and a takeoff thrust of 50 kN. This rocket was first launched on November 19, 1962, near Cuxhaven and reached a height of 40 km. # A two-stage rocket with a length of 6 metres and a takeoff thrust of 50 kN. This rocket was first launched on February 7, 1963, and reached a height of 80 km. # A three-stage rocket with a length of 12.8 metres, a diameter of 0.56 metres and a takeoff thrust of 50 kN. This rocket was first launched on May 2, 1963, with reduced fuel and reached an altitude of 110 km. Later with maximum fuel it reached a height of 150 km. All Seliger Rockets return to the ground by parachute. The single-stage version was completely reusable. Additional single and two-stage rockets were developed in 1963, which could be also used for military ... [...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).

Berthold 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 ...

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 ...

Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...
