Levasseur PL.2
The Levasseur PL.2 was a French biplane torpedo bomber designed by Pierre Levasseur for the French Navy. Design and development The second design of Pierre Levasseur was the PL.2, a single-seat unequal-span biplane inspired by designs from Blackburn Aircraft. It had a fixed tailskid landing gear and was powered by a nose-mounted Renault engine. The first of two prototypes first flew in November 1922. The second aircraft had a four-bladed propeller and other powerplant improvements. Nine production aircraft were built in 1923, these were fitted with ballonets and jettisonable landing gear for operations at sea.Taylor and Alexander 1969, pp. 102-103. Operational history The aircraft entered service in 1926 aboard the French aircraft carrier ''Béarn'' and continued in use until they were scrapped in 1932.

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".

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

Carrier-based Aircraft
Carrier-based aircraft, sometimes known as carrier-capable aircraft or carrier-borne aircraft, are naval aircraft designed for operations from aircraft carriers. They must be able to launch in a short distance and be sturdy enough to withstand the abrupt forces of launching from and recovering on a pitching deck. In addition, their wings are generally able to fold up, easing operations in tight quarters. Such aircraft are designed for many purposes including air-to-air combat, surface attack, anti-submarine warfare (ASW), search and rescue (SAR), transport (COD), weather observation, reconnaissance and airborne early warning and control (AEW&C) duties.Fred T Jane (2005). ''Jane's All the World's Aircraft''. Jane's Information Group. The term is generally applied only to fixed-wing aircraft, as naval helicopters are able to operate from a wider variety of ships, including helicopter carriers, destroyers, frigates and container ships.

Escadrille 7B2
A flight is a small military unit within the larger structure of an air force, naval air service, or army air corps; and is usually subservient of a larger squadron. A military aircraft flight is typically composed of four aircraft, though two to six aircraft may also form an aircraft flight; along with their aircrews and ground staff. In some very specific examples, typically involving historic aircraft, a flight may contain as many as twelve aircraft, as is the case with the Battle of Britain Memorial Flight (BBMF) of the British Royal Air Force (RAF). In most usages, two or more flights make up a squadron. Foreign languages equivalents include ''escadrille'' ( French), ''escuadrilla'' (Spanish), ''esquadrilha'' (Portuguese), ''zveno'' (Russian), and ''Schwarm'' (German). In the case of a non-flying, or 'ground flight', such as Mechanical Transport Flight (MTF), Supply Flight, Accounts Flight, etc; no aircraft, and a roughly equivalent number of support personnel may be ...

French Aircraft Carrier Béarn
''Béarn'' was an aircraft carrier converted from an incomplete for the (French Navy) during the 1920s. Entering service in 1928, the navy intended to use her to develop tactics and techniques for carrier aviation. The only aircraft carrier France produced until after World War II, the ship played a minor role in early stages of the war, training in home waters and conducting pilot training. In late May 1940 ''Béarn'' ferried gold to purchase aircraft from the United States, but she was diverted to Martinique in the French West Indies when the French armistice with Germany was signed in June. Under pressure from the United States, which was worried about the Germans taking control of her if she returned to France, the carrier remained there for the next four years. To placate the Americans, the local commander agreed to have her immobilized in mid-1942. The Vichy French government ordered him to sabotage the ship in May 1943 and he ultimately complied by having ''Béarn'' run ...

Ballonet
A ballonet is an air bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense. Because air is also denser than the lifting gas, inflating the ballonet reduces the overall lift, while deflating it increases lift. In this way, the ballonet can be used to adjust the lift as required. Ballonets may typically be used in non-rigid or semi-rigid airships, commonly with multiple ballonets located both fore and aft to maintain balance and to control the pitch of the airship. The image illustrates the principle of a balloon within a balloon. The outer balloon represents the airship's outer envelope or gasbag, while the red inner balloon represents the ballonet. In an airship the ballonet would be much smaller relative to the size of the gasbag; for example, in the French airship Lebaudy Patrie the volume of the ballonet was approximately one-fifth that of the envelope. History The ballonet was first descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
