Bachstelze
The Focke-Achgelis Fa 330 ''Bachstelze'' ( en, Wagtail) was a type of rotary-wing kite, known as a rotor kite. They were towed behind German U-boats during World War II to allow a lookout to see further. Development Because of their low profile in the water, submarines could not see more than a few miles over the ocean. To solve this, the German admiralty considered a number of different options, including a folding seaplane (Arado Ar 231). In the end, they chose the Fa 330, a simple, single-seat autogyro kite with a three-bladed rotor. The Fa 330 could be deployed to the deck of the submarine by two people and was tethered to the U-boat by a 150 m (500 ft) cable. The airflow on the rotors as the boat motored along on the surface would spin them up. The kite would then be deployed behind the U-boat with its observer-pilot aboard, raising him approximately 120 meters above the surface and allowing him to see much farther — about 25 nautical miles (46&nb ...

Focke-Achgelis
Focke-Achgelis & Co. G.m.b.H. was a German helicopter company founded in 1937 by Henrich Focke and Gerd Achgelis. History Henrich Focke was ousted in 1936 from the Focke-Wulf company, which he had cofounded in 1924, due to shareholder pressure. There is reason to believe that Focke's removal was to allow Focke-Wulf's manufacturing capacity to be used to produce Bf 109 aircraft. The company was taken over by AEG, but soon after this the Air Ministry, which had been impressed by the Focke-Wulf Fw 61 helicopter, suggested that Focke establish a new company dedicated to helicopter development, and issued him with a requirement for an improved design, capable of carrying a payload. Focke established the Focke-Achgelis company at Hoykenkamp, Germany, on 27 April 1937, in partnership with pilot Gerd Achgelis, and began development work at Delmenhorst in 1938.

Rotor Kite
A rotor kite or gyrokite is an unpowered, rotary-wing aircraft. Like an autogyro or helicopter, it relies on lift created by one or more sets of rotors in order to fly. Unlike a helicopter, gyrokites and rotor kites do not have an engine powering their rotors, but while an autogyro has an engine providing forward thrust that keeps the rotor turning, a rotor kite has no engine at all, and relies on either being carried aloft and dropped from another aircraft, or by being towed into the air behind a car or boat or by use of ambient winds for the kiting. As of 2009, no country in the world requires a license to pilot such a craft.

Autogyro
An autogyro (from Greek and , "self-turning"), also known as a ''gyroplane'', is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down. The autogyro was invented by Spanish engineer Juan de la Cierva in an attempt to create an aircraft that could fly safely at low speeds. He first flew one on 9 January 1923, at Cuatro Vientos Airfield in Madrid. The aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller. Cierva's autogyro is considered the predecessor of the modern helicopter. The success of the autogyro garnered the interest of industrialists and under license from Cierva in the 1920s and 1930s, the Pitcairn & Kellett compan ...

Kite
A kite is a tethered heavier than air flight, heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs don’t need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from kite (bird), kite, the hovering bird of prey. The Lift (force), lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal Drag (physics), drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the rope, lines or tethers to which t ...

Deutsches Technikmuseum
(German Museum of Technology) in Berlin, Germany is a museum of science and technology, and exhibits a large collection of historical technical artifacts. The museum's main emphasis originally was on rail transport, but today it also features exhibits of various sorts of industrial technology. In 2003, it opened both maritime and aviation exhibition halls in a newly built extension. The museum also contains a science center called Spectrum. History The Museum of Traffic and Technology (') was founded in 1982 and assumed the tradition of the Royal Museum of Traffic and Construction (') which was opened in the former station building in 1906. The present-day museum is located on the former freight yard attached to the in the district of Berlin, including two historic roundhouses and several office buildings. Renamed ' in 1996, the exhibition area was gradually expanded. An adjacent new building complex was inaugurated in 2003, topped by a prominent US Air Force Douglas C-47B ...

Hubschraubermuseum Bückeburg
The Hubschraubermuseum Bückeburg (Bückeburg Helicopter Museum) is located in the German town of Bückeburg, 30 miles (50 km) to the west of Hanover. The museum is the sole museum in Germany specialising in rotary-wing flight and one of few worldwide. The museum is dedicated to the history and technology of the helicopter. History Sergeant Major Werner Noltemeyer gathered parts, models, books and photographs of rotary-wing aircraft while he was training to become a helicopter pilot in the German Army Aviation Corps. In 1959 the German School of Army Aviation was established in Bückeburg. In the late 1960s, the city council of Bückeburg offered Noltemeyer an old timbered-framed building for use as a museum which opened in 1971. Due to a shortage of space an additional exhibition hall was added in 1980. The museum was further expanded with a glass addition in 2011. Hubschrauberzentrum e. V. The ''Hubschrauberzentrum e. V.''

RAF Museum Cosford
The Royal Air Force Museum Cosford, located in Cosford in Shropshire, is a free (currently, 2022) museum dedicated to the history of aviation and the Royal Air Force in particular. The museum is part of the Royal Air Force Museum, a non-departmental public body sponsored by the Ministry of Defence and also a registered charity. The museum is spread over two sites in England; the other site is at the Royal Air Force Museum London at Colindale (near Hendon) in north London. History The London museum was officially opened at the Colindale (then part of Hendon) London site on 15 November 1972 by Queen Elizabeth II. The hangars housed just 36 aircraft at opening. Over the years, the collection increased and aircraft were stored at RAF stations around the country when they were not on display to the public. On 1 May 1979, the Cosford site was opened at RAF Cosford, one of the RAF stations which had been used to store the museum's collection of aircraft. On opening, the museum initi ...

Science Museum At Wroughton
The National Collections Centre, near Swindon, England, is the collections management facility for the Science Museum Group and the Science Museum Library & Archives. Overview The Science Museum originally took ownership of the 545-acre former RAF Wroughton airfield in 1979, to be used as a storage facility for the museum's largest objects. A collection of approximately 35,000 objects is currently stored in six of the hangars and a purpose-built store. These include the world's first hovercraft, MRI scanners, computers, (de-activated) nuclear missiles and much more. In 2007 the collection of the Science Museum Library and Archives was also relocated to new facilities at the site. In 2016 the site started to be featured in ''The Grand Tour'', a motoring entertainment show. The show's three ex 'Top Gear' hosts use some of the roads surrounding the museum buildings as a vehicle test track each week. In 2018 the site was rebranded as the National Collections Centre to reflect th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
