Short Type 81
The Short Admiralty Type 81 was a series of British two-seat floatplanes built prior to the First World War, and used by the Royal Naval Air Service in the early years of the war. They were powered by Gnome Lambda-Lambda 14 cylinder two-row rotary engines and had folding wings to aid storage on ship, hence the popular name Short Folder, shared with a number of other seaplanes made by Short Brothers. Design and development During 1913, Short Brothers received orders for two new types of floatplanes for the British Royal Naval Air Service (RNAS), a two- bay biplane powered by a Gnome Lambda-Lambda twin-row rotary engine, of which two were ordered, and a lighter and less powerful three-bay biplane powered by a Gnome Omega-Omega, (the Short Admiralty Type 74) of which seven were ordered.Barnes 1967, p. 91. The first of these to appear was the 160 hp Gnome-powered aircraft, the first of which had the Shorts construction number ''S.63'' and the Royal Navy serial numb ...

Aspect Ratio (wing)
In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing has a low aspect ratio.Kermode, A.C. (1972), ''Mechanics of Flight'', Chapter 3, (p.103, eighth edition), Pitman Publishing Limited, London Aspect ratio and other features of the planform are often used to predict the aerodynamic efficiency of a wing because the lift-to-drag ratio increases with aspect ratio, improving the fuel economy in powered airplanes and the gliding angle of sailplanes. Definition The aspect ratio \text is the ratio of the square of the wingspan b to the projected wing area S, which is equal to the ratio of the wingspan b to the standard mean chord \text: \text \equiv \frac = \frac Mechanism As a useful simplification, an airplane in flight can be imagined to affect a circular cylinder of air with a diameter equal to th ...

Sopwith Special
The Sopwith Special torpedo seaplane Type C was the first British aircraft designed to drop torpedoes. A single-engine biplane floatplane, it flew in July 1914 but proved unable to lift the design load and was soon abandoned. Design and development The Admiralty's interest in torpedo delivery by aircraft began in November 1913, expressed by an order placed with Sopwith for a "mock-up" seaplane torpedo carrier, the Sopwith Type TT. This was intended only to taxi, not fly; its trials extended over the following May and June. In February 1914, before trials of the Type TT had begun, this contract was extended to include a second, flying, experimental torpedo carrying seaplane. The resulting Special torpedo seaplane Type C was delivered to RNAS Calshot on 1 July 1914, carrying the RNAS serial number 170. The Special was a four-bay biplane, with square-tipped, constant- chord, unequal-span wings connected by pairs of parallel interplane struts. The 4 ft (1.2 m) overhangs ...

Fleet Review (Commonwealth Realms)
A fleet review or naval review is an event where a gathering of ships from a particular navy is paraded and reviewed by an incumbent head of state and/or other official civilian and military dignitaries. A number of national navies continue to hold fleet reviews. Fleet reviews may also include participants and warships from multiple navies. Commonwealth realms Fleet reviews in the Commonwealth realms are typically observed by the reigning monarch or their representative, a practice allegedly dating back to the 15th century. Such an event is not held at regular intervals and originally only occurred when the fleet was mobilised for war or for a show of strength to discourage potential enemies, or during periods of commemorations. Since the 19th century, they have often been held for the coronation or for special royal jubilees and increasingly included delegates from other national navies. Traditionally, a fleet review will have participating ships dressed in flags and pennants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spithead
Spithead is an area of the Solent and a roadstead off Gilkicker Point in Hampshire, England. It is protected from all winds except those from the southeast. It receives its name from the Spit, a sandbank stretching south from the Hampshire shore for . Spithead is long by about in average breadth. Spithead has been strongly defended since 1864 by four Solent Forts, which complement the Fortifications of Portsmouth. The Fleet Review is a British tradition that usually takes place at Spithead, where the monarch reviews the massed Royal Navy. The Spithead mutiny occurred in 1797 in the Royal Navy fleet at anchor at Spithead. It is also the location where sank in 1782 with the loss of more than 800 lives.

HMS A7
HMS ''A7'' was an submarine built for the Royal Navy in the first decade of the 20th century. She sank in a training accident in 1914 with the loss of her entire crew. Efforts to salvage her failed and her wreck is a protected site. Diving on her is prohibited without a licence from the Ministry of Defence. Design and description ''A7'' was a member of the first British class of submarines, although slightly larger, faster and more heavily armed than the lead ship, . The submarine had a length of overall, a beam of and a mean draft of . They displaced on the surface and submerged. The A-class submarines had a crew of 2 officers and 9 ratings.Gardiner & Gray, p. 86 For surface running, the boats were powered by a single 16-cylinder Wolseley petrol engine that drove one propeller shaft. When submerged the propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, ''A7'' had a range of at ; submerged the boat had a ran ...

Great Yarmouth
Great Yarmouth (), often called Yarmouth, is a seaside town and unparished area in, and the main administrative centre of, the Borough of Great Yarmouth in Norfolk, England; it straddles the River Yare and is located east of Norwich. A population of 38,693 in the 2011 Census made it Norfolk's third most populous. Its fishing industry, mainly for herring, shrank after the mid-20th century and has all but ended. North Sea oil from the 1960s supplied an oil-rig industry that services offshore natural gas rigs; more recently, offshore wind power and other renewable energy industries have ensued. Yarmouth has been a resort since 1760 and a gateway from the Norfolk Broads to the North Sea. Holiday-making rose when a railway opened in 1844, bringing easier, cheaper access and some new settlement. Wellington Pier opened in 1854 and Britannia Pier in 1858. Through the 20th century, Yarmouth boomed as a resort, with a promenade, pubs, trams, fish-and-chip shops, theatres, the Pleasu ...

Water Landing
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaplane Tender
A seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War. Terminology In maritime parlance a tender is a vessel that is used to support the operation of other vessels. In British usage, the term tender was used for small craft, with the term depot ship being used for large seagoing vessels. Flying boats and float planes even when based at home in ports and harbour had a need for small support vessels to operate.p British tenders were small craft of launch to pinnace size. These were used to ferry crews, stores and supplies between shore and the aircraft, to maintain the buoys used to mark out "taxiways" and "runways" and to keep these clear of debris to prevent foreign object damage, and in the case of ...

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cowling
A cowling is the removable covering of a vehicle's engine, most often found on automobiles, motorcycles, airplanes, and on outboard boat motors. On airplanes, cowlings are used to reduce drag and to cool the engine. On boats, cowlings are a cover for an outboard motor. In addition to protecting the engine, outboard motor cowlings need to admit air while keeping water out of the air intake. Etymology "Cowling" comes from "cowl", which originated from Middle English coule, from Old English cūle, from earlier cugele (“hood, cowl”). This, in turn, came from Ecclesiastical Latin cuculla (“monk's cowl”), from Latin cucullus (“hood”), of uncertain origin. In aviation In aviation, a cowling may be used for drag reduction or engine cooling by directing airflow. Examples in aviation include the NACA cowling and Townend ring. On an airplane, the cowling may also cover part of the fuselage, the nacelles, the engine mount and part of the cockpit.Aviation Machinist's Mates' Manua ...
