Xi'an KJ-600
The Xi'an KJ-600 is a Chinese twin-propeller, quad-tail, high-wing military aircraft designed for cargo and airborne early warning and control (AEW&C), intended to be deployed on Type 003 aircraft carriers of the People's Liberation Army Navy from around 2024. Design and development The KJ-600 is a high-straight wing aircraft reportedly powered by a pair of WJ-6 turboprop engine, and sports a quad-fin tailplane, tricycle gear and a large dorsal radome suspected to be fitted with an AESA-type system. A non-flying model was observed on a concrete mockup carrier at Wuhan electronic testing facility, The mockup has a striking external resemblance to the aftward-folding Northrop Grumman E-2 Hawkeye. The design is likely to be a case of form following function, as the cancelled Soviet Yakovlev Yak-44 shared the same layout. The aircraft made its maiden flight on 29 August 2020. Flight testing continued in 2021. A prototype in flight was spotted by aircraft observers above the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turb ...

The National Interest
''The National Interest'' (''TNI'') is an American bimonthly international relations magazine edited by American journalist Jacob Heilbrunn and published by the Center for the National Interest, a public policy think tank based in Washington, D.C., that was established by former U.S. President Richard Nixon in 1994 as the Nixon Center for Peace and Freedom. The magazine is associated with the realist school of international studies. History Founded in 1985 by American columnist and neoconservatism advocate Irving Kristol, the magazine was until 2001 edited by Australian academic Owen Harries. In 2001, The National Interest was acquired by The Center for the National Interest, a public policy think tank based in Washington, D.C., that was established by former U.S. President Richard Nixon on January 20, 1994, as the Nixon Center for Peace and Freedom.

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev Yak-44
The Yakovlev Yak-44 (russian: link=yes, Як-44) was a proposed twin-turboprop Airborne Early Warning (AEW) aircraft, resembling the United States Navy's E-2 Hawkeye, intended for use with the Soviet Navy's ''Ulyanovsk'' class supercarriers. Along with the aircraft carrier it would have flown from, the Yak-44 was cancelled after the demise of the Soviet Union. A full-scale mockup with foldable wings was built. Design and development In the late 1970s, the Soviet Navy adopted a plan to build large aircraft carriers capable of operating conventional aircraft rather than the VSTOL Yakovlev Yak-38s operated by the existing Kiev class aircraft carriers. These new carriers required a shipborne airborne early warning (AEW) aircraft to be effective, and the Yakovlev design bureau was instructed to develop such an aircraft in 1979.Gardiner and Chumbley 1995, p. 372.Gordon, Komissarov and Komissarov 2005, p. 347. While the AEW would be the primary role for the aircraft, it was also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Form Follows Function
Form follows function is a principle of design associated with late 19th and early 20th century architecture and industrial design in general, which states that the shape of a building or object should primarily relate to its intended function or purpose. Origins of the phrase The architect Louis Sullivan coined the maxim, which resumes Viollet-le-Duc's théories : ''a rationally designed structure may not necessarily be beautiful but no building can be beautiful that does not have a rationally designed structure''. The maxim is often incorrectly attributed to the sculptor Horatio Greenough (18051852), whose thinking mostly predates the later functionalist approach to architecture. Greenough's writings were for a long time largely forgotten, and were rediscovered only in the 1930s. In 1947, a selection of his essays was published as ''Form and Function: Remarks on Art by Horatio Greenough''. Sullivan was Greenough's much younger compatriot and admired rationalist thinker ...

Northrop Grumman E-2 Hawkeye
The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin- turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete. The aircraft's performance has been upgraded with the E-2B and E-2C versions, where most of the changes were made to the radar and radio communications due to advances in electronic integrated circuits and other electronics. The fourth major version of the Hawkeye is the E-2D, which first flew in 2007. The E-2 was the first aircraft designed specifically for its role, as opposed to a modification of an existing airframe, such as the Boeing E-3 Sentry. Variants of the Hawkeye have been in continuous production since 1960, giving it the longest production run of any carrier-based aircraft. The E-2 also r ...

Folding Wing
A folding wing is a wing configuration design feature of aircraft to save space and is typical of carrier-based aircraft that operate from the limited deck space of aircraft carriers. The folding allows the aircraft to occupy less space in a confined hangar because the folded wing normally rises over the fuselage decreasing the floor area of the aircraft. Vertical clearance is also limited in aircraft carrier hangar decks. In order to accommodate for this, some aircraft such as the Supermarine Seafire and Fairey Gannet have additional hinges to fold the wingtips downward, while others such as the S-3 Viking have folding tails. The F-14 Tomcat's variable-sweep wings could be "overswept" to occupy less space. History Short Brothers, the world's first aircraft manufacturer, developed and patented folding wing mechanisms for biplane ship-borne aircraft like their Short Folder, the first patent being granted in 1913. The Folder's biplane wings were hinged so that they folded bac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wuhan
Wuhan (, ; ; ) is the capital of Hubei Province in the People's Republic of China. It is the largest city in Hubei and the most populous city in Central China, with a population of over eleven million, the ninth-most populous Chinese city and one of the nine National Central Cities of China. The name "Wuhan" came from the city's historical origin from the conglomeration of Wuchang, Hankou, and Hanyang, which are collectively known as the "Three Towns of Wuhan" (). Wuhan lies in the eastern Jianghan Plain, at the confluence of the Yangtze river and its largest tributary, the Han River, and is known as "Nine Provinces' Thoroughfare" (). Wuhan has historically served as a busy city port for commerce and trading. Other historical events taking place in Wuhan include the Wuchang Uprising of 1911, which led to the end of 2,000 years of dynastic rule. Wuhan was briefly the capital of China in 1927 under the left wing of the Kuomintang (KMT) government. The city later serve ...

Mockup
In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup may be a '' prototype'' if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: "You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer". Applications Mockups are used as design tools virtually everywhere a new product is designed. Mockups are used in the automotive device industry as part of the product development process, where dimensions, overall impression, and shapes are tested in a wind tunnel experiment. They can also be used to test consumer reaction. Systems engineering Mockups, wireframes and prototypes are not so clean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
