1963 BAC One-Eleven Test Crash
The 1963 BAC One-Eleven test crash was a fatal accident of a British Aircraft Corporation prototype aircraft on 22 October 1963, near Chicklade in Wiltshire, England while it was undertaking a test flight. All seven crew members on board the BAC One-Eleven were killed. Accident The accident occurred during a test flight of the first prototype BAC One-Eleven (registration G-ASHG) which had taken off from Wisley Airfield with seven crew on board, piloted by Mike Lithgow. The aircraft was on its fifth test flight to assess stability and handling characteristics during the approach to—and recovery from—a stall with the centre of gravity in varying positions. From an altitude of and with the flaps extended 8°, the aircraft entered a stable stall and descended at a high rate in a horizontal attitude, eventually striking the ground with very little forward speed. The aircraft broke up on impact at Cratt Hill, near Chicklade, a small village in southern Wiltshire and ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Stall
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller ...

Gloss (annotation)
A gloss is a brief notation, especially a marginal one or an interlinear one, of the meaning of a word or wording in a text. It may be in the language of the text or in the reader's language if that is different. A collection of glosses is a ''glossary.'' A collection of medieval legal glosses, made by glossators, is called an ''apparatus''. The compilation of glosses into glossaries was the beginning of lexicography, and the glossaries so compiled were in fact the first dictionaries. In modern times a glossary, as opposed to a dictionary, is typically found in a text as an appendix of specialized terms that the typical reader may find unfamiliar. Also, satirical explanations of words and events are called glosses. The German Romantic movement used the expression of gloss for poems commenting on a given other piece of poetry, often in the Spanish style. Glosses were originally notes made in the margin or between the lines of a text in a classical language; the meaning of a wor ...

Accidents And Incidents Involving The BAC One-Eleven
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into some ...

Aviation Accidents And Incidents In England
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the ...

British European Airways Flight 548
British European Airways Flight 548 was a scheduled passenger flight from London Heathrow to Brussels that crashed near Staines, Surrey, England, soon after take-off on 18 June 1972, killing all 118 people on board. The accident became known as the Staines air disaster. , it remains the deadliest air accident (as opposed to terrorist incidents) in the United Kingdom and was the deadliest air accident involving a Hawker Siddeley Trident. Two passengers initially survived the impact but died soon after from their injuries. The aircraft suffered a deep stall in the third minute of its flight and crashed to the ground, narrowly missing a busy main road. The public inquiry principally blamed the captain for failing to maintain airspeed and configure the high-lift devices correctly. It also cited the captain's heart condition and the limited experience of the co-pilot, while noting an unspecified "technical problem" that the crew apparently resolved before take-off. The crash took ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1966 Felthorpe Trident Crash
On 3 June 1966, a newly built Hawker Siddeley Trident jetliner crashed during a pre-delivery test flight near the village of Felthorpe, Norfolk, England, killing all four crew. The aeroplane had entered a deep stall from which the crew were unable to recover. It was the first loss of a Trident aircraft. Aircraft The aircraft involved was a tri-jet Hawker Siddeley Trident 1C, registration serial number 2126; that was about to be delivered to British European Airways. Accident flight The aircraft was making its first flight, which was a routine test flight to enable the aircraft's Certificate of Airworthiness to be issued. There were four crew on board. The aircraft took off from Hatfield Aerodrome at 16:52. Tests established that the stick shaker operated at , and that stall recovery system operated at . The crew then disconnected the stall warning systems in order to ascertain the actual margin left after the warning had been given before the aircraft stalled. On this ...

Samuel Taylor Coleridge
Samuel Taylor Coleridge (; 21 October 177225 July 1834) was an English poet, literary critic, philosopher, and theologian who, with his friend William Wordsworth, was a founder of the Romantic Movement in England and a member of the Lake Poets. He also shared volumes and collaborated with Charles Lamb, Robert Southey, and Charles Lloyd. He wrote the poems '' The Rime of the Ancient Mariner'' and '' Kubla Khan'', as well as the major prose work '' Biographia Literaria''. His critical work, especially on William Shakespeare, was highly influential, and he helped introduce German idealist philosophy to English-speaking cultures. Coleridge coined many familiar words and phrases, including " suspension of disbelief". He had a major influence on Ralph Waldo Emerson and American transcendentalism. Throughout his adult life, Coleridge had crippling bouts of anxiety and depression; it has been speculated that he had bipolar disorder, which had not been defined during his lifet ...

The Rime Of The Ancient Mariner
''The Rime of the Ancient Mariner'' (originally ''The Rime of the Ancyent Marinere'') is the longest major poem by the English poet Samuel Taylor Coleridge, written in 1797–1798 and published in 1798 in the first edition of ''Lyrical Ballads''. Some modern editions use a revised version printed in 1817 that featured a gloss. Along with other poems in ''Lyrical Ballads'', it is often considered a signal shift to modern poetry and the beginning of British Romantic literature. ''The Rime of the Ancient Mariner'' recounts the experiences of a sailor who has returned from a long sea voyage. The mariner stops a man who is on his way to a wedding ceremony and begins to narrate a story. The Wedding-Guest’s reaction turns from bemusement to impatience to fear to fascination as the mariner's story progresses, as can be seen in the language style: Coleridge uses narrative techniques such as personification and repetition to create a sense of danger, the supernatural, or serenity, ...

Stick-pusher
A stick pusher is a device installed in some fixed-wing aircraft to prevent the aircraft from entering an aerodynamic stall. Some large fixed-wing aircraft display poor post-stall handling characteristics or are vulnerable to deep stall. To prevent such an aircraft approaching the stall the aircraft designer may install a hydraulic or electro-mechanical device that pushes forward on the elevator control system whenever the aircraft's angle of attack reaches the pre-determined value, and then ceases to push when the angle of attack falls sufficiently. A system for this purpose is known as a stick pusher. The safety requirements applicable to fixed-wing aircraft in the transport category, and also to many military aircraft, are relatively demanding in the area of pre-stall handling qualities and stall recovery. Some of these aircraft are unable to comply with these safety requirements relying solely on the natural aerodynamic qualities of the aircraft. In order to comply with regul ...
