Ann Harvey
Ann Harvey (1811–1860) was a fisher and rescuer born near the small fishing community of Isle aux Morts, Newfoundland. Harvey, called the "Grace Darling of Newfoundland", is known for her bravery at the age of seventeen for rescuing, along with her father, younger brother and their Newfoundland dog, 163 shipwrecked people from the brig '' Despatch'' between July 12–15, 1828. ''Despatch'' had departed from Derry in late May, carrying nearly 200 Irish immigrants (and 11 crew members) bound for Quebec City, but on July 10, a fierce storm wrecked the brig on the rocks near Isle aux Morts. Life The Harveys lived, along with one or two other families, on a small, bare, rocky island near Isle aux Morts. Ann's father, George, was born in Jersey, and moved to Newfoundland with his wife, where they had eight children, of whom Ann was the eldest. Ann married Charles Gillam and together they had eight children. Rescue Ann and her father were fishing as usual one early July morning when ...

Bow Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship to doc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Bell 412
The Bell 412 is a utility helicopter of the Huey family manufactured by Bell Helicopter. It is a development of the Bell 212, with the major difference being the composite four-blade main rotor. Design and development Development began in the late 1970s with two Bell 212s being converted into 412 prototypes. An advanced four-blade main rotor with a smaller diameter replaced the 212's two-blade rotor. A Bell 412 prototype first flew in August 1979. The initial model was certified in January 1981 with deliveries commencing in the same month. The 412 model was followed by the 412SP (Special Performance) version featuring larger fuel capacity, higher takeoff weight and optional seating arrangements. In 1991, the 412HP (High Performance) variant with improved transmission replaced the SP version in production. The current production version, 412EP (Enhanced Performance), is equipped with a dual digital automatic flight control system. In 2013 Bell introduced the 412EPI which include ...

Bell 206
The Bell 206 is a family of two-bladed, single- and twin-engined helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec, plant. Originally developed as the Bell YOH-4 for the United States Army's Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation "B06" is used on flight plans for the JetRanger and LongRanger, and the designation "B06T" is used for the twin-engined TwinRangers. Development Origins and JetRanger On October 14, 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a req ...

MBB Bo 105
The Messerschmitt-Bölkow-Blohm Bo 105 is a light, twin-engine, multi-purpose helicopter developed by Bölkow of Ottobrunn, West Germany. It was the first light twin-engine helicopter in the world, and the first rotorcraft that could perform aerobatic maneuvers such as inverted loops.Moll 1991, p. 96. The Bo 105 features a revolutionary hingeless rotor system, a pioneering innovation in helicopters when it was introduced into service in 1970. Production of the Bo 105 began at the then-recently merged Messerschmitt-Bölkow-Blohm (MBB). The main production facilities for producing the Bo 105 were located in Germany and Canada; due to the level of export sales encountered, additional manufacturing lines were set up in Spain, Indonesia, and the Philippines. MBB became a part of Eurocopter in 1991, who continued production of the type until 2001. The Bo 105 was formally replaced in Eurocopter's product range by the newer Eurocopter EC135. Development In 1964, development work beg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese Akagi and battleship Kaga, were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner . The armoured flight deck was another innovation pioneered by the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

Racal Decca
The Decca Radar company was a British manufacturer of radar systems. There were originally two divisions, Marine and Heavy Radar, with separate product lines. The latter was sold to Plessey in 1965, and the term "Decca Radar" normally refers to the Marine division. That division remained with Decca until 1979 when it purchased by Racal to form Racal-Decca. After a series of further mergers and purchases, from 2000 the division is part of Northrop Grumman. Decca is best known for its marine radars, starting with 1949's Type 159. Their most successful line was the 1970s Bridgemaster series which continued sales into the 2000s. Under Plessey, the company was particularly successful in the US pleasure boat market. The Heavy Radar division produced the AMES Type 80 radars for the Royal Air Force, and used that technology to develop the Decca HF200 height finder radar. This led to the Decca Air Surveillance Radar, which spawned a number of adaptations for civilian and military use. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
