Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Córdoba, Spain
Córdoba (; ),, Arabic: قُرطبة DIN: . or Cordova () in English, is a city in Andalusia, Spain, and the capital of the province of Córdoba. It is the third most populated municipality in Andalusia and the 11th overall in the country. The city primarily lies on the right bank of the Guadalquivir, in the south of the Iberian Peninsula. Once a Roman settlement, it was taken over by the Visigoths, followed by the Muslim conquests in the eighth century and later becoming the capital of the Umayyad Caliphate of Córdoba. During these Muslim periods, Córdoba was transformed into a world leading center of education and learning, producing figures such as Maimonides, Averroes, Ibn Hazm, and Al-Zahrawi, and by the 10th century it had grown to be the second-largest city in Europe. Following the Christian conquest in 1236, it became part of the Crown of Castile. Córdoba is home to notable examples of Moorish architecture such as the Mezquita-Catedral, which was named as a UNE ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jean Marie Le Bris
Jean Marie Le Bris (March 25, 1817, Concarneau – February 17, 1872, Douarnenez) was a French aviator, born in Concarneau, Brittany who built two glider aircraft and performed at least one flight on board of his first machine in late 1856. His name () is sometimes spelled Jean-Marie Le Bris, and he is also known as Yann Vari Ar Briz () in Breton language. Early life Jean Marie Le Bris was born in Concarneau, Brittany, France on March 25, 1817 at 5AM local time. He was the third child of Michel Marie Le Bris, boat captain, and Perrine Rosalie Le Bris née Riou. Jean Marie Le Bris married Jeanne Louise Alexandrine Kerisit in Pont-Croix on February 18, 1844.

George Cayley
Sir George Cayley, 6th Baronet (27 December 1773 – 15 December 1857) was an English engineer, inventor, and aviator. He is one of the most important people in the history of aeronautics. Many consider him to be the first true scientific aerial investigator and the first person to understand the underlying principles and forces of flight and the first man to create the wire wheel. * * * In 1799, he set forth the concept of the modern aeroplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation." He identified the four forces which act on a heavier-than-air flying vehicle: weight, lift, drag and thrust. Modern aeroplane design is based on those discoveries and on the importance of cambered wings, also proposed by Cayley. He constructed the first flying model aeroplane and also diagrammed the elements of vertical flight. He also designed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Galata Tower
The Galata Tower ( tr, Galata Kulesi), officially the Galata Kulesi Museum ( tr, Galata Kulesi Müzesi), is an old Genoese tower in the Galata part of the Beyoğlu district of Istanbul, Turkey. Built as a watchtower at the highest point of the (lost) Walls of Galata, the tower is now an exhibition space and museum, and a symbol of Beyoğlu and Istanbul. History During the Byzantine period the Emperor Justinian had a tower erected in what was to become Galata. This tower was destroyed during the Fourth Crusade in 1204. In 1267 a Genoese colony was established in the Galata part of Constantinople. It was surrounded by walls and the Galata Tower was first built at their highest point as the ''Christea Turris'' (Tower of Christ) in Romanesque style in 1348 during an expansion of the colony. At the time the Galata Tower, at , was the tallest building in the city.Katie Hallam (2009). ''The Traveler's Atlas: Europe''. London: Barron's Educational Series.(2009), p. 118-119. After the ...

Bosphorus
The Bosporus Strait (; grc, Βόσπορος ; tr, İstanbul Boğazı 'Istanbul strait', colloquially ''Boğaz'') or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul in northwestern Turkey. It forms part of the continental boundary between Asia and Europe, and divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation. Most of the shores of the Bosporus Strait, except for the area to the north, are heavily settled, with the city of Istanbul's metropolitan population of 17 million inhabitants extending inland from both banks. The Bosporus Strait and the Dardanelles Strait at the opposite end of the Sea of Marmara are together known as the Turkish Straits. Sections of the shore of the Bosporus in Istanbul have been reinforced with concrete or rubble and those sections of the Strait prone to deposition are periodically dredged. Name The name of the ...

Malmesbury Abbey
Malmesbury Abbey, at Malmesbury in Wiltshire, England, is a religious house dedicated to Saint Peter and Saint Paul. It was one of the few English houses with a continuous history from the 7th century through to the dissolution of the monasteries. Monastic history In the later seventh century, the site of the Abbey was chosen by Maildubh, an Irish monk who established a hermitage, teaching local children. Toward the end of his life, in the late seventh century, the area was conquered by the Saxons.''Blackwell Encyclopedia of Anglo Saxon England'', p. 209. Malmesbury Abbey was founded as a Benedictine monastery around 676 by the scholar-poet Aldhelm, a nephew of King Ine of Wessex. The town of Malmesbury grew around the expanding Abbey and under Alfred the Great was made a burh, with an assessment of 12 hides. In AD 941, King Æthelstan was buried in the Abbey. Æthelstan had died in Gloucester in October 939. The choice of Malmesbury over the New Minster in Winchester indicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
