Xian H-20
The Xian H-20 (; alternatively Xian H-X) is a projected subsonic stealth bomber design of the People's Liberation Army Air Force. It is referred to as a strategic project by the People's Liberation Army. The H-20 will be the first dedicated strategic bomber developed by China. The aircraft may enter service in the 2020s. The development of a strategic bomber was revealed in September 2016.Grossman et al.: page 50 Design and development In 2016, People's Liberation Army Air Force (PLAAF) general Ma Xiaotian announced that China was developing a new type of long-range bomber on the air force's open day. In 2018, a Chinese military spokesperson confirmed the development was making "great progress". According to the United States Department of Defense, the H-20 is expected to be a flying wing with a range of at least 8,500 km and a payload capacity of at least 10 tonnes; according to the Rand Corporation, an American funded thinktank, it will allow China "to reliably threaten U.S. ...

Stealth Aircraft
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft specifically designed around stealth technology. Other examples of stealth aircraft include the B-2 Spirit, the B-21 Raider, the F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is totally invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft successfully avoiding detection by enemy radar and/or avoiding being successfully targeted by radar guided weapons. Stealth is the combination of passive low observable (LO) features and active emitters such as low-probability-of-intercept radars, radios and laser designators. These are usually com ...

Serration
Serration is a saw-like appearance or a row of sharp or tooth-like projections. A serrated cutting edge has many small points of contact with the material being cut. By having less contact area than a smooth blade or other edge, the applied pressure at each point of contact is greater and the points of contact are at a sharper angle to the material being cut. This causes a cutting action that involves many small splits in the surface of the material being cut, which cumulatively serve to cut the material along the line of the blade. In nature, serration is commonly seen in the cutting edge on the teeth of some species, usually sharks. However, it also appears on non-cutting surfaces, for example in botany where a toothed leaf margin or other plant part, such as the edge of a carnation petal, is described as being serrated. A serrated leaf edge may reduce the force of wind and other natural elements. Probably the largest serrations on Earth occur on the skylines of mountains ...

Northrop Grumman B-21 Raider
The Northrop Grumman B-21 Raider is an American strategic bomber under development for the United States Air Force (USAF) by Northrop Grumman. As part of the Long Range Strike Bomber (LRS-B) program, it is to be a long-range, stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. The Air Force is planning to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit with the B-21 by 2040, and could possibly replace the Boeing B-52 Stratofortress after that. The Air Force began planning for the B-21 in 2011 and awarded the major development contract in 2015. The B-21 is expected to make its first flight in 2023 and enter service by 2027. Many aspects of the B-21 program are highly classified; the program is designated as a special access program.

V-tail
The V-tail or ''Vee-tail'' (sometimes called a butterfly tail or Rudlicki's V-tailGudmundsson S. (2013). "General Aviation Aircraft Design: Applied Methods and Procedures" (Reprint). Butterworth-Heinemann. p. 489. , 9780123973290) of an aircraft is an unconventional arrangement of the tail control surfaces that replaces the traditional fin and horizontal surfaces with two surfaces set in a V-shaped configuration. It is not widely used in aircraft design. The aft edge of each twin surface is a hinged control surface called a ruddervator, which combines the functions of both a rudder and elevator. The V-tail was invented in 1930 by Polish engineer Jerzy Rudlicki and was tested for the first time on the Hanriot H-28 trainer aircraft, modified by a Polish aerospace manufacturer Plage and Laśkiewicz in the summer of 1931. Variants The X-shaped tail surfaces of the experimental Lockheed XFV were essentially a V tail that extended both above and below the fuselage. Conventional ...

Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Tail
A twin tail is a specific type of vertical stabilizer arrangement found on the empennage of some aircraft. Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer. This arrangement is also known as an H-tail,Schiff, Barry: ''Flying'', page 15. Golden Press, New York, 1971. Library of Congress 78-103424 as it resembles a capital "H" when viewed from the rear. The twin tail was used on a wide variety of World War II multi-engine designs that saw mass production, especially on the American B-24 Liberator and B-25 Mitchell bombers, the British Avro Lancaster and Handley Page Halifax heavy bombers, and the Soviet Union's Petlyakov Pe-2 attack bomber. Variations on the twin tail include the triple tail, twin boom tail and double tail. Design Separating the control surfaces allows for additional rudder area or vertical surface without requiring a massive single tail. On ...

Strategic Bomber
A strategic bomber is a medium- to long-range Penetrator (aircraft), penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombing, tactical bombers, Penetrator (aircraft), penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, Military base, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical bombing, tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after Strategic bombing during World War II, strategic bombing was widely employed, and Atomic bombing ...
