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 Flugzeugwerke, 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. Development 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 ...

Air Superiority Fighter
An air superiority fighter (also styled 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 airstrike, 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 aircraft, interceptor, escort fighter, night fighter, and so forth. With the development of heat seeking and radar guided missiles in the 1950s, design diverged between fighters optimized to not fight in range of the enemy’s guns; as these missile technologies progressed, so did fighter doctrine. In the United States, the influential prevalenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Countermeasure
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place durin ... [...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 Argentina de Aviones (FAdeA) 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 clamshe ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. 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 Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

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.Gunston and Gilchrist 1993, pp. 188-189. 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 su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanium
Titanium is a chemical element; it has 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 (TiO2), 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 cata ... [...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 ...

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. 245 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 HAL in Kanpur, India, and transported to Oberpfaffenhofen, where RUAG Aviation carries out aircraft final assembly. The Dornier 228NG uses the 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 Atomics. Development Origins In the late 1970s, Dornie ...

Dassault/Dornier Alpha Jet
The Dassault/Dornier Alpha Jet is a attack aircraft, light attack jet aircraft, jet and advanced jet trainer co-manufactured by Dassault Aviation of France and Dornier Flugzeugwerke of Germany. It was developed specifically to perform trainer and light attack missions, as well as to perform these duties better than the first generation of jet trainers that preceded it. Following a competition, a design submitted by a team comprising Breguet Aviation, Dassault Aviation, and Dornier Flugzeugwerke, initially designated as the ''TA501'', was selected and subsequently produced as the Alpha Jet. Both the French Air and Space Force and West German Air Force procured the Alpha Jet in large numbers, the former principally as a trainer aircraft and the latter choosing to use it as a light attack platform. As a result of post-Cold War military cutbacks, Germany elected to retire its own fleet of Alpha Jets in the 1990s and has re-sold many of these aircraft to both military and civilian op ...

General Electric F404
The General Electric F404 and F412 are a family of afterburning turbofan engines in the class (static thrust). The series is produced by GE Aerospace. Partners include Volvo Aero, which builds the RM12 variant. The F404 was developed into the larger F414 turbofan, as well as the experimental GE36 civil propfan. Design and development F404 GE developed the F404 for the F/A-18 Hornet, shortly after losing the competition for the F-15 Eagle's engine to Pratt & Whitney, and losing the Lightweight Fighter (LWF) competition to the Pratt & Whitney F100 powered YF-16. For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum thrust of 16,000 lbf (71.2 kN) in the original F404-GE-400 model. ...

Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more Propel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
