Arrestor Hook
A tailhook, arresting hook, or arrester hook is a device attached to the empennage (rear) of some military fixed-wing aircraft. The hook is used to achieve rapid deceleration during routine landings aboard aircraft carrier flight decks at sea, or during emergency landings or aborted takeoffs at properly equipped airports. The tailhook was first demonstrated at sea on 18 January 1911 by the aviator Eugene Ely, having successfully landed aboard the armored cruiser USS ''Pennsylvania'' with the aid of the device. It was not until the early 1920s that a practical system, paired with deck-mounted arresting gear, was devised and put into use. During the 1930s, numerous vessels were thus equipped, permitting the use of increasingly heavy combat aircraft at sea during the Second World War. Following the introduction of jet-powered aircraft during the 1950s, arrestor technology was further advanced to permit aircraft operating at greater speeds and weights to land aboard aircraft car ...

Caught The Wire! (3579526989)
Caught is a method of dismissing a batsman in cricket. A batsman is out caught if the batsman hits the ball, from a legitimate delivery, with the bat, and the ball is caught by the bowler or a fielder before it hits the ground. If the catch is taken by the wicket-keeper, then informally it is known as caught behind or caught at the wicket. A catch by the bowler is known as caught and bowled. This has nothing to do with the dismissal bowled but is rather a shorthand for saying the catcher and bowler are the same player. (The scorecard annotation is usually ''c. and b.'' or ''c&b'' followed by the bowler's name.) Caught is the most common method of dismissal at higher levels of competition, accounting for 36,190 Test match dismissals between 1877 and 2012, which is 56.9% of all Test match dismissals in this period. South African wicket-keeper Mark Boucher holds the record for the most Test match catches, with 532, while Rahul Dravid holds the record for the most Test match ca ...

Hugh Armstrong Robinson
Hugh Armstrong Robinson (May 13, 1881 – 1963) was an American pioneer in the earliest days of aviation, combining his skills of inventor, pilot, and daredevil. Among other things, he is said to have been the third person to successfully fly an aircraft after the Wright Brothers in an aircraft of his own design and construction, and the first person to make an air-sea rescue. His many firsts also include the first medical flight transporting a doctor to patient in Hammond, N.Y. in June 1912, and the first U.S. airmail flight in 1911. Robinson also devised the term and art of dive-bombing. Biography Robinson was born on May 13, 1881, in Neosho, Missouri. In late 1910, Hugh Robinson became a pilot and chief engineer for Glenn Curtiss at Curtiss School of Aviation, Rockwell Field, North Island, North Island, San Diego. There he coined the term and invented the tailhook system that helped make possible Eugene Ely's first ever flight, on January 18, 1911, to the deck of a ship, ...

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct United States in the Vietnam War, US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian Civil War, Laotian and Cambodian Civil Wars, which ended with all three countries becoming Communism, communist in 1975. After the defeat of the French Union in the First Indoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Popular Mechanics
''Popular Mechanics'' (often abbreviated as ''PM'' or ''PopMech'') is a magazine of popular science and technology, featuring automotive, home, outdoor, electronics, science, do it yourself, and technology topics. Military topics, aviation and transportation of all types, space, tools and gadgets are commonly featured.

Allison J33
The General Electric/Allison J33 is an American centrifugal-flow jet engine, a development of the General Electric J31, enlarged to produce significantly greater thrust, starting at and ending at with an additional low-altitude boost to with water-alcohol injection. Development The J33 was originally developed by General Electric as a follow-on to their work with the designs of Frank Whittle during World War II. Their first engine was known as the General Electric I-A, but after major changes to adapt it to US production and to increase thrust, it started limited production as the I-16 in 1942, the 16 referring to its thrust. Full production started as the J31 when the United States Army Air Forces introduced common naming for all their engine projects. Along with the I-16, GE also started work on an enlarged version, known as the I-40. As the name implied, the engine was designed to provide . Apart from size, the main difference between I-16 and the I-40 was the combus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world.

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in Propeller (aircraft), propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach number, Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved did not begin to be solved until the 1930s. Frank Whittle, an English people, English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military pu ...

Hydraulics
Hydraulics () is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of Power (physics), power by the use of pressure, pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and they cover concepts such as pipe Volumetric flow rate, flow, dam design, fluidics, and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. ''Free surface hydraulics'' is the branch of hydraulics dealing with free surface flow, such as occurring in rivers ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs.

Arrestor Gear
An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems that use nets to catch aircraft wings or landing gear. These ''barricade'' and ''barrier'' systems are only used for emergency arrestments for aircraft without operable tailhooks. History Arresting cable systems were invented by Hugh Robinson and were used by Eugene Ely on his first landing on a ...

Maritime Patrol Aircraft
A maritime patrol aircraft (MPA), also known as a patrol aircraft, maritime reconnaissance aircraft, maritime surveillance aircraft, or by the older American term patrol bomber, is a fixed-wing aircraft designed to operate for long durations over water in maritime patrol roles — in particular anti-submarine warfare (ASW), anti-surface warfare, anti-ship warfare (AShW), and search and rescue (SAR). In addition to dedicated airframes, mid-size and large business jets have been modified for MPA missions, offering rapid deployment, extended range, long endurance, and lower life-cycle costs. Among other maritime surveillance resources, such as satellites, ships, unmanned aerial vehicles (UAVs) and helicopters, the MPA is an important asset. To perform ASW operations, MPAs typically carry air-deployable Sonobuoy, sonar buoys as well as torpedoes and are usually capable of extended flight at low altitudes.
