Hispano HA-200
The Hispano HA-200 Saeta (English: ''Arrow'') was a twin-seat jet advanced trainer designed and produced by Spanish aircraft manufacturer Hispano Aviación. It has the distinction of being the first Spanish aircraft to harness jet propulsion. The German aircraft designer Willy Messerschmitt can be largely credited for his role in designing the HA-200, which reused a substantial portion of the earlier piston-powered HA-100 Triana. On 12 August 1955, the first prototype conducted its maiden flight. It was not until 1962 that the first production aircraft performed its first flight. That same year, deliveries of the trainer aircraft commenced to the Spanish Air Force. It would be used in this capacity by the service for multiple decades. The HA-200 was later further developed into the Hispano Aviación Ha-220 "Super Saeta", which functioned as a dedicated ground attack platform, armed with rockets, bombs, and other munitions. The HA-220 served in the Spanish Air Force througho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano Aviación
Hispano Aviación was a Hispano-Suiza aircraft factory in Andalusia, southern Spain which became a separate enterprise when taken over by the Francisco Franco led Nationalist faction, "Nationalist" forces in 1939, during the Spanish Civil War. Located in San Pablo Airport, Tablada, in the Triana, Seville, Triana district of Seville, the Hispano factory produced several aircraft designs, including the Hispano Aviación HA-1109, HA-1109 also named Me-109J, Spanish licence built version of the famous Messerschmitt Bf-109G equipped with a 1,300 hp Hispano-Suiza 12Z engine, Hispano Aviación HA-1112, HA-1112 (HA-1109 re-engined with Rolls-Royce Merlin), Hispano HA-100 ''Triana''; the Hispano HA-200 ''Saeta'' jet trainer and light attack aircraft designed by Professor Willy Messerschmitt.Green, 1955, p.100 Hispano Aviación was taken over by Construcciones Aeronáuticas SA (CASA) in 1972, which is now part of Airbus.

Western Sahara War
The Western Sahara War ( ar, حرب الصحراء الغربية, french: Guerre du Sahara occidental, es, Guerra del Sahara Occidental) was an armed struggle between the Sahrawi indigenous Polisario Front and Morocco from 1975 to 1991 (and Mauritania from 1975 to 1979), being the most significant phase of the Western Sahara conflict. The conflict erupted after the withdrawal of Spain from the Spanish Sahara in accordance with the Madrid Accords (signed under the pressure of the Green March), by which it transferred administrative control of the territory to Morocco and Mauritania, but not sovereignty. In late 1975, the Moroccan government organized the Green March of some 350,000 Moroccan citizens, escorted by around 20,000 troops, who entered Western Sahara, trying to establish a Moroccan presence. While at first met with just minor resistance by the Polisario Front, Morocco later engaged a long period of guerrilla warfare with the Sahrawi nationalists. During the late 1970 ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Tricycle Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francoist Spain
Francoist Spain ( es, España franquista), or the Francoist dictatorship (), was the period of Spanish history between 1939 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title . After his death in 1975, Spain transitioned into a democracy. During this time period, Spain was officially known as the Spanish State (). The nature of the regime evolved and changed during its existence. Months after the start of the Spanish Civil War in July 1936, Franco emerged as the dominant rebel military leader and was proclaimed head of state on 1 October 1936, ruling a dictatorship over the territory controlled by the Nationalist faction. The 1937 Unification Decree, which merged all parties supporting the rebel side, led to Nationalist Spain becoming a single-party regime under the FET y de las JONS. The end of the war in 1939 brought the extension of the Franco rule to the whole country and the exile of Republican institutions. The Francoist dictatorshi ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CASA C-101
The CASA C-101 Aviojet is a low-wing single engine jet-powered advanced trainer and light attack aircraft designed and manufactured by Spanish aircraft company Construcciones Aeronáuticas SA (CASA). The C-101 was developed in response to a Spanish Air Force requirement, which needed a replacement for the outdated Hispano Saeta. During 1975, CASA commenced work on what would become the C-101. In addition to its own design team, technical assistance was provided by Germany's Messerschmitt-Bölkow-Blohm (MBB) and the United States' Northrop. In June 1977, the first of four prototypes performed the type's maiden flight. The design was somewhat reminiscent of other jet trainers of the era, such as the BAE Hawk and the Alpha Jet, but was less aerodynamically sophisticated, being equipped with an unswept wing. Performance of the C-101 during flight testing was reported in excess of predictions. On 17 March 1980, the first examples were introduced to operational service with the ...
