Blue Vixen
__NOTOC__ Blue Vixen was a British airborne radar designed and built for the Royal Navy by Ferranti Defence Systems (later, GEC-Marconi), Edinburgh, Scotland. It was the primary radar of later models of the British Aerospace Sea Harrier, replacing the Ferranti Blue Fox used on earlier models of the Harrier. Design and development Blue Vixen was a lightweight (145 kg) multimode, coherent, pulse-Doppler I band airborne radar, developed from the previous Ferranti Blue Fox radar, and designed for use on the British Aerospace Sea Harrier FA2. It was a multimode radar for airborne interception and air-to-surface strike roles over water and land, with look-down/shoot-down and look-up modes. Designed from the start to have full AIM-120 AMRAAM compatibility, it was also compatible with Sea Eagle and AIM-9 Sidewinder missiles. Development aircraft used Two British Aerospace 125 aircraft were used for the flight trial's program. The first (XW930 serial number 25009) was a Series 1 air ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

Sea Eagle (missile)
The BAe Sea Eagle is a medium weight sea-skimming anti-ship missile designed and built by BAe Dynamics (now MBDA). It is designed to sink or disable ships up to the size of aircraft carriers in the face of jamming and other countermeasures including decoys. Its users include the Royal Air Force and Royal Navy, the Royal Saudi Air Force, and the Indian Navy. History Previous systems The anti-ship version of the Martel missile entered service with the RAF in October 1972 and the Royal Navy one year later. These missiles were designed around a television guidance system using a camera in the nose of the missile that sent its image back to the launch aircraft via a data link radio system. The weapon officer in the aircraft, normally the Blackburn Buccaneer, used the image to guide the missile via signals sent back to the missile on the same data link. This method of operation had been chosen for its simplicity; in comparison, an active radar seeker would be prone to all sorts of ...

Aircraft Radars
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-a ...

Jane's
Jane's Information Group, now styled Janes, is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, The Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019.

List Of Rainbow Codes
The Rainbow Codes were a series of code names used to disguise the nature of various British military research projects. They were mainly used by the Ministry of Supply from the end of the Second World War until 1958, when the ministry was broken up and its functions distributed among the forces. The codes were replaced by an alphanumeric code system. History During WWII, British intelligence was able to glean details of new German technologies simply by considering their code names. For instance, when they heard of a new system known as '' Wotan'', Reginald Victor Jones asked around and found that Wotan was a one-eyed god. Based on this, he guessed it was a radio navigation system using a single radio beam. This proved correct, and the Royal Air Force was able to quickly render it useless through jamming. Wishing to avoid making this sort of mistake, Ministry of Supply (MoS) initiated a system that would be entirely random and deliberately unrelated to the program in any way, ...

PS-05/A
The PS-05/A is a pulse-doppler radar currently used by the JAS 39 Gripen fighter aircraft (JAS 39A, B, C and D variants). It weighs 156 kg and was developed by Ericsson in collaboration with GEC-Marconi, sharing some technology with the latter's Blue Vixen radar for the Sea Harrier (which inspired the Eurofighter's CAPTOR radar). The PS-05/A works in the 8–10 GHz band and has 1 kW energy output (> 10 kW maximum output). The radar is capable of detecting, locating, identifying and automatically tracking multiple targets in the upper and lower spheres, on the ground and sea or in the air, in all weather conditions. It consists of four line replaceable units and all LRUs can be replaced in 30 minutes. Gripen operator Hungarian Air Force reported the PS-05 radar set has proved reliable so far, both in domestic service and NATO flight exercises in Corsica. Versions PS-05/A Mark 3 This version of the PS-05/A radar has been available since 2005. It is capable of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euroradar CAPTOR
The Euroradar Captor is a next-generation mechanical multi-mode pulse Doppler radar designed for the Eurofighter Typhoon. Development of Captor led to the Airborne Multirole Solid State Active Array Radar (AMSAR) project which eventually produced the CAESAR (Captor Active Electronically Scanned Array Radar), now known as Captor-E. Development Development started as the ECR-90 at Ferranti's Edinburgh radar labs, home of many British radar systems. The ECR-90 was based on the Blue Vixen radar which had been developed for the BAE Sea Harrier FA2. The selection of the radar had become a major stumbling block in the EFA project, as the Eurofighter Typhoon was known at the time. Britain, Italy and Spain supported the Ferranti-led ECR-90, while West Germany preferred the MSD2000, based on the US AN/APG-65 radar family being developed in a collaboration between Hughes, AEG and GEC. An agreement was reached after the British Defence Secretary Tom King assured his West German counterp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Aircraft Establishment
The Royal Aircraft Establishment (RAE) was a British research establishment, known by several different names during its history, that eventually came under the aegis of the UK Ministry of Defence (MoD), before finally losing its identity in mergers with other institutions. The first site was at Farnborough Airfield ("RAE Farnborough") in Hampshire to which was added a second site RAE Bedford ( Bedfordshire) in 1946. In 1988 it was renamed the Royal Aerospace Establishment (RAE) before merging with other research entities to become part of the new Defence Research Agency in 1991. History In 1904–1906 the Army Balloon Factory, which was part of the Army School of Ballooning, under the command of Colonel James Templer, relocated from Aldershot to the edge of Farnborough Common in order to have enough space to inflate the new "dirigible balloon" or airship which was then under construction.Walker, P; Early Aviation at Farnborough, Volume I: Balloons, Kites and Airships, Mac ...

British Aerospace 125
The British Aerospace 125 is a twinjet mid-size business jet. Originally developed by de Havilland and initially designated as the DH.125 Jet Dragon, it entered production as the Hawker Siddeley HS.125, which was the designation used until 1977. Later on, more recent variants of the type were marketed as the Hawker 800. More than 60% of the total sales of the aircraft were to North American customers.Jerram, Mike"The last de Havilland."''Flying Magazine'', 120 (9). p. 43. It was also used by the Royal Air Force as a navigation trainer, as the Hawker Siddeley Dominie T1, and was operated by the United States Air Force as a calibration aircraft, under the designation C-29. Development Origins In 1961, de Havilland began work upon a small business jet, then known as the ''DH.125 Jet Dragon'', which was intended to replace the piston engined de Havilland Dove, a successful business aircraft and light transport. Prior to the start of the project, de Havilland had determine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Vixen Trials Aircraft Owned By Allaero
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments.

AIM-9 Sidewinder
The AIM-9 Sidewinder (where "AIM" stands for "Air Intercept Missile") is a short-range air-to-air missile which entered service with the US Navy in 1956 and subsequently was adopted by the US Air Force in 1964. Since then the Sidewinder has proved to be an enduring international success, and its latest variants remain standard equipment in most Western world, Western-aligned air forces. The Soviet Union, Soviet K-13 (missile), K-13 (AA-2 'Atoll'), a Reverse engineering#Reverse engineering for military applications, reverse-engineered copy of the AIM-9B, was also widely adopted by a number of nations. Low-level development started in the late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket. This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile.

AIM-120 AMRAAM
The AIM-120 Advanced Medium-Range Air-to-Air Missile, or AMRAAM (pronounced ), is an American Beyond-visual-range missile, beyond-visual-range air-to-air missile (BVRAAM) capable of all-weather day-and-night operations. It is 7 inches (18 cm) in diameter, and employs active transmit-receive radar guidance instead of semi-active receive-only radar guidance. It is a fire-and-forget weapon, unlike the previous generation AIM-7 Sparrow, Sparrow missiles which needed guidance from the firing aircraft. When an AMRAAM missile is launched, NATO pilots use the Multiservice tactical brevity code, brevity code Fox (code word), Fox Three. more than 14,000 had been produced for the United States Air Force, the United States Navy, and 33 international customers. The AMRAAM has been used in several engagements, achieving sixteen air-to-air kills in conflicts over Iraqi no-fly zones conflict, Iraq, Operation Deny Flight, Bosnia, Operation Allied Force, Kosovo, 2019 Jammu and Kashmir airst ...
