XF10F Jaguar
The Grumman XF10F Jaguar was a prototype swing-wing fighter aircraft offered to the United States Navy in the early 1950s. Although it never entered service, its research paved the way toward the later General Dynamics F-111 and Grumman's own F-14 Tomcat. Design and development The Navy's interest in the variable-geometry wing was based on concerns that the ever-increasing weight of its jet fighters was making aircraft carrier operations troublesome. Many of its existing aircraft already had marginal carrier performance, and the trend in weight growth was obviously upward. At the same time, the demands for high-speed performance demanded swept wing layouts that did not lend themselves to good takeoff characteristics. The prospect of combining the two in a single aircraft was enticing. Originally conceived as a swept-wing version of the earlier F9F Panther, in February–March 1948, the design was reconfigured with a T-tail and ultimately a variable-geometry wing.Winchester 2005, ...

Bell X-5
The Bell X-5 was the first Fixed-wing aircraft, aircraft capable of Variable-sweep wing, changing the sweep of its wings in flight. It was inspired by the untested wartime Messerschmitt P.1101, P.1101 design of the Germany, German Messerschmitt company. In a further development of the German design, which could only have its wing sweepback angle adjusted on the ground, the Bell engineers devised a system of electric motors to adjust the sweep in flight. Design and development The Messerschmitt P.1101 V1 prototype was captured by United States troops in April 1945 from an experimental facility at Oberammergau, Germany. It was brought back to the United States, eventually being delivered to the Bell Aircraft factory at Buffalo, New York. Although incomplete and damaged in transit, company engineering staff studied the design closely.Winchester 2005, p. 37. The P.1101 had a wing sweep that could be adjusted on the ground from 30, 40, to 45 degrees. However, this was for testing only ...

List Of Fighter Aircraft
Fighter aircraft are military aircraft primarily designed for Aerial warfare, air-to-air combat. They usually carry various weapons and missiles intended for air strikes and are used to achieve air superiority, superiority over airspaces. While these aircraft are meant for aerial warfare, and does not include aircraft used for specific roles such as List of attack aircraft, ground attack aircraft, List of bomber aircraft, bombers and Trainer aircraft, trainers, there is some overlap in roles and designs. Multirole combat aircraft are utlized for various roles and fall under multiple categories. The key performance features of a fighter apart from its firepower include its high speed and maneuverability. Fighter aircraft are sorted into Jet fighter generations, generations, from one to five, based on technological level and advancements. The fighter aircraft are often designated by a specific naming convention based on the country of origin. The name usually consists of a letter p ...

Westinghouse XJ40-WE-8
The Westinghouse J40 was an early high-performance afterburning turbojet engine designed by Westinghouse Aviation Gas Turbine Division starting in 1946 to a US Navy Bureau of Aeronautics (BuAer) request. BuAer intended to use the design in several fighter aircraft and a bomber. However, while an early low-power design was successful, attempts to scale it up to its full design power failed, and the design was finally abandoned, deemed a "fiasco" and a "flop". The design originally called for an engine of thrust at sea level static conditions without afterburner and 10,900 lbf thrust with afterburner. A more powerful model 9,500/13,700 lbf thrust version was intended to replace the earlier engines in the various airframes. In total, thirteen different variations were planned. The projected need for the higher-power engines led BuAer to place a second source production contract with Ford Motor Company, Lincoln Mercury Division for both J40-WE-10 and J40-WE-12 engines.

Naval Air Material Center
A navy, naval force, military maritime fleet, war navy, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water nav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Catapult
An aircraft catapult is a device used to help fixed-wing aircraft gain enough airspeed and lift for takeoff from a limited distance, typically from the deck of a ship. They are usually used on aircraft carrier flight decks as a form of assisted takeoff, but can also be installed on land-based runways, although this is rare. The catapult used on aircraft carriers consists of a track or slot built into the flight deck, below which is a large piston or ''shuttle'' that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle. Other forms have been used historically, such as mounting a launching cart holding a seaplane on a long girder-built structure mounted on the deck of a warship or merchant ship, but most catapults share a similar sliding track concept. Different means have been used to propel the catapult, such as weight and derrick, gunpowder, flywheel, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angled Flight Deck
The flight deck of an aircraft carrier is the surface on 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 which entered service in 1918. The armoured flight deck was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panavia Tornado
The Panavia Tornado is a family of twin-engine, variable-sweep wing multi-role combat aircraft, jointly developed and manufactured by Italy, the United Kingdom and Germany. There are three primary #Variants, Tornado variants: the Tornado IDS (interdictor/attack aircraft, strike) fighter-bomber, the Tornado ECR (electronic warfare aircraft, electronic combat/reconnaissance aircraft, reconnaissance) SEAD aircraft and the Tornado ADV (air defence variant) interceptor aircraft. The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), Messerschmitt-Bölkow-Blohm, MBB of West Germany, and Aeritalia of Italy. It first flew on 14 August 1974 and was introduced into service in 1979–1980. Due to its multirole design, it was able to replace several different types of aircraft in the adopting air forces. The Royal Saudi Air Force (RSAF) became the only export operator of the Tornad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman F-9 Cougar
The Grumman F9F/F-9 Cougar is a carrier-based jet propulsion, jet-powered fighter aircraft designed and produced by the American aircraft manufacturer Grumman. It was developed during the early 1950s on behalf of the United States Navy (US Navy) and United States Marine Corps (USMC), which were keen to quickly introduce a naval fighter equipped with a swept wing. Grumman's design team decided to adapt its earlier Grumman F9F Panther, F9F Panther, replacing the straight wing of the Panther with a new swept wing. Thrust was also increased with the installation of a newer and more powerful engine. Nevertheless, the aircraft remained limited to subsonic speeds. The first prototype (XF9F-6), which was produced by modifying an existing Panther, performed its maiden flight on 20 September 1951. The Navy considered the Cougar to be an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6. During December 1952, the F9F-6 was in ...

Jell-O
Jell-O (stylized in all caps) is an American brand offering a variety of powdered gelatin dessert (fruit-flavored gels/jellies), pudding, and no-bake cream pie mixes. The original gelatin dessert ( genericized as jello) is the signature of the brand. "Jell-O" is a registered trademark of Kraft Heinz, and is based in Chicago, Illinois. The dessert was especially popular in the first half of the 20th century. The original gelatin dessert began in Le Roy, New York, in 1897, when Pearle Bixby Wait trademarked the name ''Jell-O''. He and his wife May had made the product by adding strawberry, raspberry, orange, and lemon flavoring to sugar and granulated gelatin (which had been patented in 1845). The powder is mixed with boiling water and then cooled to produce a gel. Description Jell-O is sold prepared (ready-to-eat), or in powder form, and is available in various colors and flavors. The powder contains powdered gelatin and flavorings, including sugar or artificial sweetener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Fluid
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery. Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic fluid used has zero compressibility. Functions and properties The primary function of a hydraulic fluid is to convey power. In use, however, there are other important functions of hydraulic fluid such as protection of the hydraulic machine components. The table below lists the major functions of a hydraulic fluid and the properties of a fluid that affect its ability to perform that function: Composition Base stock The original hydraulics fluid, dating back to the time of ancient Egyp ...
