Blue Sky(missile)
Fireflash was the United Kingdom's first air-to-air guided missile to see service with the Royal Air Force. Constructed by Fairey Aviation, the missile utilised radar beam riding guidance. Fireflash had relatively limited performance and required the launching aircraft to approach the target from a limited angle astern. The approximately 300 production Fireflash missiles were mostly expended as a training weapon to familiarize RAF pilots with missile firing. It was declared operational very briefly in 1957, thus becoming the RAF's first operational air-to-air missile, but was quickly replaced by the de Havilland Firestreak the next year. Development Red Hawk In January 1945 the Air Ministry issued Operational Requirement OR.1056, given the Ministry of Supply rainbow code "Red Hawk", for an air-to-air missile. The basic design was based on studies carried out at the Royal Aircraft Establishment (RAE) on earlier weapons. Their experiments with the manually-guided Air Spani ...

Fairey Aviation
The Fairey Aviation Company Limited was a British aircraft manufacturer of the first half of the 20th century based in Hayes in Middlesex and Heaton Chapel and RAF Ringway in Cheshire. Notable for the design of a number of important military aircraft, including the Fairey III family, the Swordfish, Firefly, and Gannet, it had a strong presence in the supply of naval aircraft, and also built bombers for the RAF. After World War II the company diversified into mechanical engineering and boat-building. The aircraft manufacturing arm was taken over by Westland Aircraft in 1960. Following a series of mergers and takeovers, the principal successor businesses to the company now trade as FBM Babcock Marine Ltd, Spectris plc, and WFEL (formerly Williams Fairey Engineering Limited), the latter manufacturing portable bridges. History Founded in 1915 by Charles Richard Fairey (later Sir Richard Fairey) and Belgian engineer Ernest Oscar Tips on their departure from Short Brothers, the co ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairey Delta 2
The Fairey Delta 2 or FD2 (internal designation Type V within Fairey) is a British supersonic research aircraft that was produced by the Fairey Aviation Company in response to a specification from the Ministry of Supply for a specialised aircraft for conducting investigations into flight and control at transonic and supersonic speeds. Features included a delta wing and a drooped nose. On 6 October 1954, the Delta 2 made its maiden flight, flown by Fairey test pilot Peter Twiss; two aircraft would be produced. The Delta 2 was the final aircraft to be produced by Fairey as an independent manufacturer. The Fairey Delta 2 was the first jet aircraft to exceed in level flight. On 10 March 1956, it set a new world speed record of , exceeding the previous official record by . The Delta 2 held the absolute World Air Speed Record for over a year. It continued to be used for flight testing, and was allocated to the Royal Aircraft Establishment (RAE) in 1958. A testbed aircraft was requ ...

Cordite
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace black powder as a military propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun. Cordite was used initially in the .303 British, Mark I and II, standard rifle cartridge between 1891 and 1915; shortages of cordite in World War I led to the creation of the "Devil's Porridge" munitions factory ( HM Factory, Gretna) on the English-Scottish border, which produced 800 tonnes of cordite per annum. The UK also imported some United States–developed smokeless powders f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionize
Ionization, or Ionisation is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion. Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules and ions, or through the interaction with electromagnetic radiation. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected. Uses Everyday examples of gas ionization are such as within a fluorescent lamp or other electrical discharge lamps. It is also used in radiation detectors such as the Geiger-Müller counter or the ionization chamber. The io ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Seeking
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flares be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Of The Art
The state of the art (sometimes cutting edge or leading edge) refers to the highest level of general development, as of a device, technique, or scientific field achieved at a particular time. However, in some contexts it can also refer to a level of development reached at any particular time as a result of the common methodologies employed at the time. The term has been used since 1910, and has become both a common term in advertising and marketing, and a legally significant phrase with respect to both patent law and tort liability. In advertising, the phrase is often used to convey that a product is made with the best or latest available technology, but it has been noted that "the term 'state of the art' requires little proof on the part of advertisers", as it is considered mere puffery. The use of the term in patent law "does not connote even superiority, let alone the superlative quality the ad writers would have us ascribe to the term". Origin and history The origin of ...

RP-3
The RP-3 (from Rocket Projectile 3 inch) was a British air to ground rocket projectile introduced during the Second World War. The "3 inch" designation referred to the nominal diameter of the rocket motor tube. The use of a warhead gave rise to the alternative name of the "60-pound rocket". Though primarily an air-to-ground weapon, it saw limited use in other roles. They were generally used by British fighter-bomber aircraft against targets such as tanks, trains, motor transport and buildings, as well as by Coastal Command and Royal Navy aircraft against U-boats and ships. Use continued post-war, with the last known major operational use being during the Aden Emergency in 1964, where Hawker Hunters flew 642 sorties and fired 2,508 RP-3s in support of Radforce. Use continued until the withdrawal from Aden in November 1967, at which point the RP-3 was withdrawn from service in favour of the newer SNEB. Concerned about the possibility of shipboard radar setting off the SNEB's elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drone Aircraft
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Gloster Aircraft
The Gloster Aircraft Company was a British aircraft manufacturer from 1917 to 1963. Founded as the Gloucestershire Aircraft Company Limited during the First World War, with the aircraft construction activities of H H Martyn & Co Ltd of Cheltenham, England it produced fighters during the war. It was renamed later as foreigners found 'Gloucestershire' difficult to pronounce. It later became part of the Hawker Siddeley group and the Gloster name disappeared in 1963. Gloster designed and built several fighters that equipped the British Royal Air Force (RAF) during the interwar years including the Gladiator, the RAF's last biplane fighter. The company built most of the wartime production of Hawker Hurricanes and Hawker Typhoons for their parent company Hawker Siddeley while its design office was working on the first British jet aircraft, the E.28/39 experimental aircraft. This was followed by the Meteor, the RAF's first jet-powered fighter and the only Allied jet fighter to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Boar (bomb)
The Vickers Blue Boar was a family of British air-launched television-guided glide bombs of the 1950s which was cancelled during development. A key role was as an anti-shipping missile, using its guidance system to attack the moving targets. It would also replace unguided bombs between against point targets, or be equipped with a nuclear warhead. A smaller version was also developed for testing. The name is a randomly assigned rainbow code. The goal of the system was to allow the bomb to be guided to of its target after being dropped from a jet bomber flying at altitude. It could manoeuvre at up to 3.5G so that it could quickly be aimed after breaking through cloud cover as low as . Nuclear-armed versions were primarily intended to provide the launching aircraft with some stand-off range and avoid overflying the target, gliding about from the launch point. In this role, guidance using H2S radar instead of the television camera was considered. Development was cancelled when i ...
