Westland Wasp
The Westland Wasp is a small 1960s British turbine powered, shipboard anti-submarine helicopter. Produced by Westland Helicopters, it came from the same P.531 programme as the British Army Westland Scout, and is based on the earlier piston-engined Saunders-Roe Skeeter. It fulfilled the requirement of the Royal Navy for a helicopter small enough to land on the deck of a frigate and carry a useful load of two homing torpedoes. The Wasp sank one ship in combat, seriously damaging the ARA ''Santa Fe'' submarine in 1982 during the Falklands war. Design and development The increasing speed and attack range of the submarine threat, and the increased range at which this threat could be detected led to a Royal Navy requirement for a "Manned Torpedo-Carrying Helicopter" (MATCH). Contemporary shipboard weapons did not have the necessary range, therefore MATCH was in essence a stand-off weapon with the helicopter carrying the torpedo or other weapon to the target and being instructed ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. Fo ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

Ditching
In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water surface in an aircraft not designed for the purpose, a very rare occurrence. Controlled flight into the surface and uncontrolled flight ending in a body of water (including a runway excursion into water) are generally not considered water landings or ditching. Aircraft water landings By design Seaplanes, flying boats, and amphibious aircraft are designed to take off and alight on water. Alighting can be supported by a hull-shaped fuselage and/or pontoons. The availability of a long effective runway was historically important on lifting size restrictions on aircraft, and their freedom from constructed strips remains useful for transportation to lakes and other remote areas. The ability to loiter on water is also important for marine resc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caster
A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling Material handling involves short-distance movement within the confines of a building or between a building and a transportation vehicle. It uses a wide range of manual, semi-automated, and automated equipment and includes consideration of the pro ... equipment. High capacity, heavy duty casters are used in many industrial applications, such as platform trucks, carts, assemblies, and tow lines in plants. Types Casters may be fixed to roll along a straight line path, or mounted on a pivot or pintle such that the wheel will automatically align itself to the direction of travel. Rigid casters A basic, rigid caster consists of a wheel mounted to a stationary fork. The orientation of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navalised
{{refimprove, date=February 2011 A navalised aircraft (or navalized aircraft) is an aircraft that has been specifically designed for naval use, in some cases as a variant of a land-based design. An aircraft based on an aircraft carrier is called carrier-based aircraft. Characteristics A navalised aircraft typically differs from its land-based equivalent by: * The airframe, engine and avionics are marinised against salt water corrosion. * It is designed to be used on a flight deck. For a fixed wing aircraft this typically means catapult attachment points, a tailhook and strengthened undercarriage. Naval helicopters usually have wheels rather than skids and may have mechanisms to attach to the deck. * It is designed to occupy minimum hangar space – for example the wings, tail-boom or rotors may fold. * There is enhanced protection against water ingress (including that from hosing down with fresh water to get rid of salt water). * Equipment such as sensors and weapons are optim ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
