Sir Barnes Wallis
Sir Barnes Neville Wallis (26 September 1887 – 30 October 1979) was an English engineer and inventor. He is best known for inventing the bouncing bomb used by the Royal Air Force in Operation Chastise (the "Dambusters" raid) to attack the dams of the Ruhr Valley during World War II. The raid was the subject of the 1955 film '' The Dam Busters'', in which Wallis was played by Michael Redgrave. Among his other inventions were his version of the geodetic airframe and the earthquake bomb. Early life and education Barnes Wallis was born in Ripley, Derbyshire, to Charles William George Robinson Wallis (1859–1945) and his wife Edith Eyre Wallis née Ashby (1859–1911). He was educated at Christ's Hospital in Horsham and Haberdashers' Aske's Hatcham Boys' Grammar School in southeast London, leaving school at seventeen to start work in January 1905 at Thames Engineering Works at Blackheath, southeast London. He subsequently changed his apprenticeship to J. Samuel White's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sub-lieutenant
Sub-lieutenant is usually a junior officer rank, used in armies, navies and air forces. In most armies, sub-lieutenant is the lowest officer rank. However, in Brazil, it is the highest non-commissioned rank, and in Spain, it is the second highest non-commissioned rank. As a naval rank, a sub-lieutenant usually ranks below a lieutenant. Armies and air force rank In France, a sub-lieutenant () is the junior commissioned officer in the army or the air force. He wears a band in the colour of his corps (e.g. gold for infantry, silver for armoured cavalry, etc.). During the 18th century a rank of existed in the French Navy. It was the equivalent of the master's mate rank of the Royal Navy. It is now replaced by the rank of "first ensign" (). An Argentinian sub-lieutenant wears a single silver sun on each shoulder, Brazilian sub-lieutenants are the most senior non-commissioned rank (called Sub-Officer in the Navy and Air force), wearing a golden lozenge. In Mexico, the sub-lieute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Dam Busters (film)
''The Dam Busters'' is a 1955 British epic war film starring Richard Todd and Michael Redgrave. It was directed by Michael Anderson. The film recreates the true story of Operation Chastise when in 1943 the RAF's 617 Squadron attacked the Möhne, Eder, and Sorpe dams in Nazi Germany with Barnes Wallis's ''bouncing bomb''. The film was based on the books '' The Dam Busters'' (1951) by Paul Brickhill and '' Enemy Coast Ahead'' (1946) by Guy Gibson. The film's reflective last minutes convey the poignant mix of emotions felt by the characters – triumph over striking a successful blow against the enemy's industrial base is tempered by the sobering knowledge that many died in the process of delivering it. The film was widely praised and became the most popular motion picture at British cinemas in 1955. In 1999, the British Film Institute voted ''The Dam Busters'' the 68th greatest British film of the 20th century. Its depiction of the raid, along with a similar sequence in the ...

Aeroplanes
An airplane or aeroplane (informally plane) is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometersMeasured in RTKs—an RTK is one tonne of revenue freight carried one kilometer. of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones. The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight".

Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Designer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, stru ...

University Of London External Programme
The University of London Worldwide (previously called the University of London International Academy) is the central academic body that manages external study programmes within the collegiate university, federal University of London. All courses are branded as simply "University of London", having previously been "University of London International Programmes" and earlier "University of London External Programmes". It claims to be the world's oldest distance and flexible learning body, established under the University of London's royal charter of 1858, although academics have disputed whether it offered distance learning at that time. Several member institutions of the University of London offer degrees through the programme, including Birkbeck, University of London, Birkbeck, Goldsmiths, University of London, Goldsmiths, King's College London, London School of Economics, London School of Hygiene & Tropical Medicine, Queen Mary, University of London, Queen Mary, Royal Holloway, Un ...
