Rogožarski IK-3
The Rogožarski IK-3 was a 1930s Yugoslav monoplane single-seat fighter, designed by Ljubomir Ilić, Kosta Sivčev and Slobodan Zrnić as a successor to the Ikarus IK-2 fighter. Its armament consisted of a hub-firing autocannon and two fuselage-mounted synchronised machine guns. It was considered comparable to foreign aircraft such as the Messerschmitt Bf 109E and came into service in 1940. The prototype crashed during testing; twelve production aircraft had been delivered by July 1940. Six IK-3s were serviceable when the Axis invasion of Yugoslavia began on 6 April 1941. All six were in service with the 51st Independent Fighter Group at Zemun near Belgrade. Pilots flying the IK-3 claimed 11 Axis aircraft had been shot down during the 11-day war. According to one account, to prevent them from falling into German hands, the surviving aircraft and incomplete airframes were destroyed by their crews and factory staff. Another account suggests that one aircraft survived the invas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter (aircraft)
Fighter aircraft are fixed-wing aircraft, fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. ...

Zemun
Zemun ( sr-cyrl, Земун, ; hu, Zimony) is a municipality in the city of Belgrade. Zemun was a separate town that was absorbed into Belgrade in 1934. It lies on the right bank of the Danube river, upstream from downtown Belgrade. The development of New Belgrade in the late 20th century expanded the continuous urban area of Belgrade and merged it with Zemun. The town was conquered by the Kingdom of Hungary in the 12th century and in the 15th century it was given as a personal possession to the Serbian despot Đurađ Branković. After the Serbian Despotate fell to the Ottoman Empire in 1459, Zemun became an important military outpost. Its strategic location near the confluence of the Sava and the Danube placed it in the center of the continued border wars between the Habsburg and the Ottoman empires. The Treaty of Belgrade of 1739 finally placed the town into Habsburg possession, the Military Frontier was organized in the region in 1746, and the town of Zemun was granted the rig ...

Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary figh ...

Hawker Hurricane
The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–40s which was designed and predominantly built by Hawker Aircraft Ltd. for service with the Royal Air Force (RAF). It was overshadowed in the public consciousness by the Supermarine Spitfire during the Battle of Britain in 1940, but the Hurricane inflicted 60 percent of the losses sustained by the Luftwaffe in the campaign, and fought in all the major theatres of the Second World War. The Hurricane originated from discussions between RAF officials and aircraft designer Sir Sydney Camm about a proposed monoplane derivative of the Hawker Fury biplane in the early 1930s. Despite an institutional preference for biplanes and lack of interest by the Air Ministry, Hawker refined their monoplane proposal, incorporating several innovations which became critical to wartime fighter aircraft, including retractable landing gear and the more powerful Rolls-Royce Merlin engine. The Air Ministry ordered Hawker's ''Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano-Suiza 12Y
The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520. Its design was based on the earlier, and somewhat smaller, 12X. The 12X did not see widespread use before the 12Y replaced it and became one of the most powerful French designs on the eve of the war. The 12Z was being designed but this was ended by the fall of France and the German occupation. The 12Y was produced under Hispano-Suiza licence in the Soviet Union as the Klimov M-100. This design led to the highly successful Klimov VK-105 series that powered the Yakovlev and Lavochkin fighters as well as the Petlyakov Pe-2 bomber. Licensed production of the early models was also undertaken in Czechoslovakia as the Avia HS 12Ydrs and in Switzerland as the HS-77. Design and devel ...

Ze (Cyrillic)
Ze (З з; italics: ) is a letter of the Cyrillic script. It commonly represents the voiced alveolar fricative , like the pronunciation of in "zebra". ''Ze is romanized using the Latin letter'' . The shape of Ze is very similar to the Arabic numeral three , and should not be confused with the Cyrillic letter E . History and shape Ze is derived from the Greek letter Zeta (Ζ ζ). In the Early Cyrillic alphabet its name was (''zemlja''), meaning "earth". The shape of the letter originally looked similar to a Greek or Latin letter Z with a tail on the bottom (). Though a majuscule form of this variant () is encoded in Unicode, historically it was only used as caseless or lowercase.Ponomar Project. ''The Complete Character Range for Slavonic Script in Unicode.'' In the Cyrillic numeral system, Zemlja had a value of 7. Medieval Cyrillic manuscripts and Church Slavonic printed books have two variant forms of the letter Zemlja: з and . Only the form was used in ...

Gull Wing
The gull wing is an aircraft wing configuration, known also as ''Pulaski wings'', with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles. Numerous aircraft have incorporated such wings for a diverse range of purposes. The gull wing was commonly used to improve visibility in a high wing arrangement, because such wing could be thinnest by the fuselage, and in theory should limit pilot's view no more than A-pillars of a windscreen in a car body. Gliders were the first aircraft to feature the gull wing, starting with the Weltensegler in 1921; it was not until the record-breaking Fafnir at the end of that decade did the configuration gain popularity. Beyond becoming popular for the next three decades amongst high-performance gliders, various ground-based aircraft and flying boats also adopted various forms of gull wings. It rose to particular prominence in Poland, where the Polish aviation designer Zygmunt P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Avia BH-33
The Avia BH-33 was a biplane fighter aircraft built in Czechoslovakia in 1927. It was based on the BH-21J which demonstrated promising results by combining the original BH-21 airframe with a licence-built Bristol Jupiter radial engine. Other than the peculiar Avia hallmark of having an upper wing with a shorter span than the lower, it was utterly conventional, even featuring a tail fin for the first time in a Pavel Beneš and Miroslav Hajn design (previous aircraft had a rudder but no fin). Design and development Initial tests of the first prototype were disappointing, displaying performance only marginally better than the BH-21, even when fitted with a more powerful version of the Jupiter. Two further prototypes followed, both designated BH-33-1, each with an increasingly powerful Jupiter variant – one a Jupiter VI, the other a Jupiter VII. The performance of the latter example was finally acceptable for the Czechoslovakian defence ministry to order a small production run ...
