SAIA 90
The FMA SAIA 90 was a cancelled air superiority fighter aircraft project, designed by the FMA ( Fábrica Militar de Aviones) with the collaboration of Dornier in the mid-1980s. The SAIA 90 was the last stage of the ACA (Avión Caza Argentino) project, which was started by the National Reorganization Process to develop an Argentine fighter aircraft. History By 1980 the Fabrica Militar de Aviones and Dornier had an ongoing relationship as a result of the combined development of the IA 63, and both were considered a cooperative agreement for the production of future airplanes. This agreement called to both parties to establish a common office in the city of Córdoba, Argentina within the year for the production, marketing and associated support services of their products. The development of a trainer was the first of three steps in Fábrica Argentina de Aviones' strategy, elaborated after the development of the IA 58 Pucará by the mid-1960s. The steps of this strategy includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Superiority Fighter
An air superiority fighter (or air-superiority fighter) is a fighter aircraft designed to seize control of enemy airspace by establishing tactical dominance ( air superiority) over the opposing air force. Air-superiority fighters are primarily tasked to perform aerial combat against agile, lightly armed aircraft (most often enemy fighters) and eliminate any challenge over control of the airspace, although some (e.g. strike fighters) may have a secondary role for air-to-surface attacks. Evolution of the term During World War II and through the Korean War, fighters were classified by their role: heavy fighter, interceptor, escort fighter, night fighter, and so forth. With the development of guided missiles in the 1950s, design diverged between fighters optimized to fight in the beyond visual range (BVR) regime (interceptors), and fighters optimized to fight in the within visual range (WVR) regime (air-superiority fighters). In the United States, the influential proponents of B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Identification Friend Or Foe
Identification, friend or foe (IFF) is an identification system designed for command and control. It uses a transponder that listens for an ''interrogation'' signal and then sends a ''response'' that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly and to determine their bearing and range from the interrogator. IFF is used by both military and civilian aircraft. IFF was first developed during World War II, with the arrival of radar, and several friendly fire incidents. IFF can only positively identify friendly aircraft or other forces. If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as foe; friendly forces may not properly reply to IFF for various reasons such as equipment malfunction, and parties in the area ...

Attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se'', although fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FMA IA 63 Pampa
The IA-63 Pampa is an advanced jet trainer with combat capability, produced in Argentina by Fabrica Militar de Aviones (FMA) with assistance from Dornier of Germany. Design and development Preliminary design studies for a replacement for the Morane-Saulnier MS-760 of the Argentine Air Force started at the Fábrica Militar de Aviones (FMA) in 1978, with these studies resulting in selection of a proposal powered by a single Garrett TFE731 turbofan with high, unswept wings. At the same time the FMA signed a partnership agreement with Dornier to develop the new aircraft.Flores 1987, pp. 59–60. Although influenced by the Dassault/Dornier Alpha Jet design, the Pampa differs in being a smaller aircraft, it is also single-engined and has straight supercritical wings rather than the swept ones of the Alpha Jet. It is constructed mainly of aluminium alloy, with carbon-fibre used for components such as the air intakes. The crew of two sit in tandem under a single-piece clamshell canop ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Intake Ramp
An intake ramp is a rectangular, plate-like device within the air intake of a jet engine, designed to generate a number of shock waves to aid the inlet compression process at supersonic speeds. The ramp sits at an acute angle to deflect the intake air from the longitudinal direction. At supersonic flight speeds, the deflection of the air stream creates a number of oblique shock waves at each change of gradient along at the ramp. Air crossing each shock wave suddenly slows to a lower Mach number, thus increasing pressure. Ideally, the first oblique shock wave should intercept the air intake lip, thus avoiding air spillage and pre-entry drag on the outer boundary of the deflected streamtube. For a fixed geometry intake at zero incidence, this condition can only be achieved at one particular flight Mach number, because the angle of the shock wave (to the longitudinal direction) becomes more acute with increasing aircraft speed. More advanced supersonic intakes feature a ramp with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon-fiber-reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addit ...

Do 228
The Dornier 228 is a twin-turboprop STOL utility aircraft, designed and first manufactured by Dornier GmbH (later DASA Dornier, Fairchild-Dornier) from 1981 until 1998. Two hundred and forty-five were built in Oberpfaffenhofen, Germany. In 1983, Hindustan Aeronautics Limited (HAL) bought a production licence and manufactured another 125 aircraft in Kanpur, Uttar Pradesh, India. In July 2017, 63 aircraft were still in airline service. In 2009, RUAG started building a Dornier 228 New Generation in Germany. The fuselage, wings and tail unit are manufactured by Hindustan Aeronautics Limited (HAL) in Kanpur, India, and transported to Oberpfaffenhofen, where RUAG Aviation carries out aircraft final assembly. The Dornier 228NG use same airframe with improved technologies and performances, such as a new five-blade propeller, glass cockpit and longer range. The first delivery was made in September 2010 to a Japanese operator. In 2020, RUAG sold the Dornier 228 program to General Atomic ...
