Badge Of The Royal Air Force
The badge of the Royal Air Force is the Heraldic badge, heraldic emblem used to represent the Royal Air Force (RAF). It features an eagle superimposed on a circlet, which is surmounted by a crown. Description The badge was based on a design by a tailor at Gieves & Hawkes, Gieves Ltd of Savile Row in London. It was first used in August 1918, and the original circlet showed a garter (stockings), garter and buckle. The present plain circlet dates from 26 January 1923 when the badge was registered at the College of Arms and, it being noted that the garter and buckle were heraldically incorrect, a substitution was made. In Heraldry, heraldic terms, the badge is blazoned as: "In front of a circle inscribed with the motto and ensigned by the Imperial Crown an eagle volant and affronté head lowered and to the sinister." Although there have been debates among airmen over the years about whether the bird was originally meant to be an albatross or an eagle, the consensus is that it was a ...

Air Vice Marshal
Air vice-marshal (Air Vce Mshl or AVM) is an air officer rank used by some air forces, with origins from the Royal Air Force. The rank is also used by the air forces of many Commonwealth of Nations, countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Air vice-marshal is usually equivalent to the naval rank of rear admiral or a rank of major general in an army. The rank of air vice-marshal is immediately senior to the rank of air commodore and immediately subordinate to the rank of air marshal. Since before the Second World War it has been common for air officers commanding RAF Group (air force), groups to hold the rank of air vice-marshal. In small air forces such as the Royal New Zealand Air Force and the Ghana Air Force, the head of the air force holds the rank of air vice-marshal. The equivalent rank in the Women's Auxiliary Air F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell 206
The Bell 206 is a family of two-bladed, single- and twin-engined helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec, plant. Originally developed as the Bell YOH-4 for the United States Army's Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation "B06" is used on flight plans for the JetRanger and LongRanger, and the designation "B06T" is used for the twin-engined TwinRangers. Development Origins and JetRanger On October 14, 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a req ...

The Mil Mi-24 (; NATO reporting name: Hind) is a large helicopter gunship, attack helicopter and low-capacity transport helicopter, troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and was introduced by the Soviet Air Forces, Soviet Air Force in 1972. The helicopter is currently in use by 58 countries. In NATO circles, the export versions, Mi-25 and Mi-35, are denoted with a letter suffix as "Hind D" and "Hind E". Soviet pilots called the Mi-24 the "flying tank" (), a term used historically with the famous World War II Soviet Ilyushin Il-2#"The Flying tank", Il-2 ''Shturmovik'' armored ground attack aircraft. Other common unofficial nicknames were "Galina" (or "Galya"), "Crocodile" (), due to the helicopter's camouflage scheme, and "faceted glass, Drinking Glass" (), because of the flat glass plates that surround earlier Mi-24 variants' cockpits. Development During the early 1960s, it became apparent to Soviet designer Mikhail Mil th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chengdu J-7
The Chengdu J-7 (wikt:歼, Chinese: 歼-7; third generation export version F-7; NATO reporting name: Fishcan) is a People's Republic of China, Chinese fighter aircraft. It is a licensed production, license-built version of the Soviet Mikoyan-Gurevich MiG-21, and thus shares many similarities with that aircraft. The aircraft is armed with short-range, infrared homing Air-to-air missile, air-to-air missiles and is mainly designed for short range air-to-air combat. The aircraft is also used for close air support. On 30 March 1962, the Soviet Union and China signed a technology transference arrangement pertaining to the MiG-21. Allegedly, while various kits, components, completed aircraft and associated documents were delivered to the Shenyang Aircraft Corporation, Shenyang Aircraft Factory, the design documentation was incomplete, and Chinese designers made efforts to Reverse engineering, reverse engineer the aircraft. While the two aircraft are greatly similar, areas of difference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IAI Kfir
The Israel Aircraft Industries Kfir (, "Lion Cub") is an Israeli all-weather multirole combat aircraft based on the French Dassault Mirage 5, with Israeli avionics and an Israeli-built version of the General Electric J79 turbojet engine. Development Background The project that would ultimately give birth to the Kfir can be traced back to the Israel Defense Forces, IDF's need for adapting the Dassault Mirage IIIC to the specific requirements of the Israeli Air Force (Israeli Air Force, IAF). The all-weather, delta-winged Mirage IIICJ was the first Mach 2 aircraft acquired by Israel from France–Israel relations, then-close ally France, and constituted the backbone of the IAF during most of the 1960s, until the arrival of the Douglas A-4 Skyhawk and, most importantly, the McDonnell Douglas F-4 Phantom II, by the end of the decade. While the Mirage IIICJ proved to be extremely effective in the air-superiority role, its relatively short range imposed some limitations on its useful ...

Ensign (flag)
An ensign is a maritime flag that is used for the national identification of a ship. It is the largest flag and is generally flown at the stern (rear) of the ship while in port. Depending on the ship's origin, it may sometimes be identical with a Jack (flag), jack on the Bow (watercraft), bow of the ship when in a port. Jacks are more common on Warship, warships than on Merchant ship, merchant ships. Etymology The Middle English is derived from the Latin word . Vexillology Vexillologists distinguish between three varieties of ensigns: *A state ensign or government ensign (Vexillological symbol, usage symbol ) is worn by government vessels of official government agencies or civilian equipped auxiliary ships. *A naval ensign (usage symbol ) is worn by a country's navy as a war flag for military ships. The term "war flag" is used irrespective of if a given country is at war. Large versions of naval ensigns called battle ensigns are used when a warship goes into battle. The ensign ...

Air Force Ensign Of Sri Lanka
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fin Flash
Military aircraft insignia are insignia applied to military aircraft to visually identify the nation or branch of military service to which the aircraft belong. Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time. History France The first use of national insignia on military aircraft was before the First World War by the French ''Aéronautique Militaire'', which mandated the application of roundels in 1912. The chosen design was the French national cockade, which consisted of a blue-white-red emblem, going outwards from centre to rim, mirroring the colours of the French flag. In addition, aircraft rudders were painted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fin Flash Of Sri Lanka
A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation. Fins first evolved on fish as a means of locomotion. Fish fins are used to generate thrust and control the subsequent motion. Fish and other aquatic animals, such as cetaceans, actively propel and steer themselves with pectoral and tail fins. As they swim, they use other fins, such as dorsal and anal fins, to achieve stability and refine their maneuvering.Helfman G, Collette BB, Facey DE and Bowen BW (2009"Functional morphology of locomotion and feeding" Chapter 8, pp. 101–116. In:''The Diversity of Fishes: Biology'', John Wiley & Sons. . The fins on the tails of cetaceans, ichthyosaurs, metriorhynchids, mosasaurs and plesiosaurs are ca ...
