Zendmast Ruiselede
The Zendmasts of Ruiselede were eight high guyed radio masts at Ruiselede, Belgium, built in 1923 for carrying an aerial for VLF transmission (nominal frequency 16.2 kHz). On 30 December 1933, an Imperial Airways aircraft crashed into a mast and demolished it. Most of the masts were blown up by German troops in October 1940. The masts were designed by the Belgian engineer Arthur Vierendeel Arthur Vierendeel (10 April 1852 – 8 November 1940) was a civil engineer born in Leuven, Belgium. He had a career as a university professor, and civil engineer. The structure known as the Vierendeel truss is named after him. Biography H ....

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruiselede
Ruiselede (; vls, Ruuslee; historically Ruysselede) is a municipality located in the Belgian province of West Flanders. This town only comprises the town of Ruiselede proper.

Imperial Airways
Imperial Airways was the early British commercial long-range airline, operating from 1924 to 1939 and principally serving the British Empire routes to South Africa, India, Australia and the Far East, including Malaya and Hong Kong. Passengers were typically businessmen or colonial administrators, and most flights carried about 20 passengers or less. Accidents were frequent: in the first six years, 32 people died in seven incidents. Imperial Airways never achieved the levels of technological innovation of its competitors and was merged into the British Overseas Airways Corporation (BOAC) in 1939. BOAC in turn merged with the British European Airways (BEA) in 1974 to form British Airways. Background The establishment of Imperial Airways occurred in the context of facilitating overseas settlement by making travel to and from the colonies quicker, and that flight would also speed up colonial government and trade that was until then dependent upon ships. The launch of the airline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1933 Imperial Airways Ruysselede Crash
The 1933 Imperial Airways Ruysselede crash occurred on 30 December 1933 when an Imperial Airways Avro Ten collided with one of the radio masts of Belradio at Ruysselede, West Flanders, Belgium and crashed killing all ten people on board. The aircraft was operating an international scheduled passenger flight from Cologne, Germany to London, England via Brussels, Belgium. Aircraft The accident aircraft was Avro Ten registration G-ABLU, c/n 528. The aircraft had entered service with Imperial Airways in May 1931 and having served for a time with Iraq Petroleum Transport Co., it had returned to Imperial Airways. The aircraft was named ''Apollo''. Accident Operating a flight from Cologne, Germany to Croydon Airport, United Kingdom via Haren Airport, Brussels, Belgium, the aircraft departed at 12:20 local time (11:20 GMT), which was 20 minutes later than scheduled.

Arthur Vierendeel
Arthur Vierendeel (10 April 1852 – 8 November 1940) was a civil engineer born in Leuven, Belgium. He had a career as a university professor, and civil engineer. The structure known as the Vierendeel truss is named after him. Biography He obtained an MSc in construction and mining engineering in 1874 at the ''Université catholique de Louvain'', after which he worked as an engineer for the company '' Nicaise et Delcuve'' in La Louvière, Belgium. In 1885 he became Director for the Ministry of Public Works in West Flanders, and four years afterward also achieved the post of Professor of Construction, Material Strength, and Structural Engineering at the ''Université catholique de Louvain''. The idea of a bridge without trusses came to him in 1895; the design later became known as a Vierendeel bridge. For the 1897 World Fair at Brussels he built a 31.5m span bridge at his own expense and loaded to show the correlation between measurement and his numerical analysis. His work, ...

Radio Masts And Towers In Europe
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In West Flanders
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towers In Belgium
A tower is a tall Nonbuilding structure, structure, taller than it is wide, often by a significant factor. Towers are distinguished from guyed mast, masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation tower, observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek language, Greek τύ ...

Demolished Buildings And Structures In Belgium
Demolition (also known as razing, cartage, and wrecking) is the science and engineering in safely and efficiently tearing down of buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes. For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through wo ...
