Aero Ae 50
The Aero Ae 50 was a prototype propeller-driven military reconnaissance aircraft built in Czechoslovakia. Designed with the artillery spotting role in mind, the Ae 50 was a high-wing monoplane of unusual design, with a fuselage that terminated abruptly immediately aft of the crew cabin, leaving the tailplane to be mounted on a single boom attached to the wing. The tailwheel was mounted at the rear of the fuselage. This arrangement had been intended to maximise the observer's field of view. Another unusual feature was that it incorporated a towing point to allow it to be towed by another, longer-range aircraft to enable it to be transported to a combat zone outside of its own range without having to stop and refuel. First flown on 14 April 1949, it was evaluated against the Praga E-55 for a defence ministry contract. The Ae 50 was found to have a range of flaws, including directional stability and the operation of the leading-edge slots. These problems were overcome, but the prob ...

Aero Vodochody
Aero Vodochody (commonly referred to as Aero) is a Czech aircraft company. Its main production facilities are located at Vodochody Airport in the Prague-East District, on the municipal territories of Vodochody and Odolena Voda. During the Cold War era, the firm was well known for its range of jet-powered trainer aircraft, the L-29 Delfin and L-39 Albatros. It also developed derivatives of the L-39, the L-59 Super Albatros and the L-159 Alca military light combat jet. Aero Vodochody is believed to have handled the biggest aircraft industrial programme to take place across any of the Council for Mutual Economic Assistance (COMECON) countries except for the Soviet Union itself. Following the fall of the communist government in Czechoslovakia during 1989, Aero Vodochody experienced a disruptive period of business, having lost a major portion of the market for its jet trainers. Sales noticeably declined during the 1990s in Eastern Europe as well as in NATO countries as a resul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconnaissance Aircraft
A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement. An example is the PBY Catalina maritime patrol flying boat used by the Allies in World War II: a flight of U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island, beginning the Battle of Midway. History Prior to the 20th century machines for powered and controllable flight were not available to military forces, but some attempts were made to use lighter than air craft ...

Artillery Spotting
An artillery observer, artillery spotter or forward observer (FO) is responsible for directing artillery and mortar fire onto a target. It may be a ''forward air controller'' (FAC) for close air support (CAS) and spotter for naval gunfire support (NGSF). Also known as fire support specialist (FiSTer), an artillery observer usually accompanies a tank or infantry maneuver unit. Spotters ensure that indirect fire hits targets which the troops at the fire support base cannot see. Because artillery is an indirect fire weapon system, the guns are rarely in line-of-sight of their target, often located miles away. The observer serves as the eyes of the guns, by sending target locations and if necessary corrections to the fall of shot, usually by radio. More recently, a mission controller for an Army Unmanned Air System (UAS) may also perform this function, and some armies use special artillery patrols behind the enemy's forward elements. Special forces such as the British SAS, US SEA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Praga E-55
Praga is a district of Warsaw, Poland. It is on the east bank of the river Vistula. First mentioned in 1432, until 1791 it formed a separate town with its own city charter. History The historical Praga was a small settlement located at the eastern bank of the Vistula river, directly opposite the towns of Old Warsaw and Mariensztat, both being parts of Warsaw now. First mentioned in 1432, it derived its name from the Polish verb ''prażyć'', meaning ''to burn'' or ''to roast'', as it occupied a forested area that was burnt out to make place for the village. Separated from Warsaw by a wide river, it developed independently of the nearby city, and on 10 February 1648 king Władysław IV of Poland granted Praga with a city charter. However, as it was mostly a suburb and most buildings were wooden, the town was repeatedly destroyed by fires, floods and foreign armies. Currently the only surviving historical monument from that epoch is the Church of Our Lady of Loreto. Alth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Minor 4-III
The Walter Minor is a family of four- and six-cylinder inverted inline air-cooled engines, developed under auspices of ing. Šimůnek and used on light aircraft. First produced in 1929, the Minor engines' family has an advanced design for the period and sports steel cylinders, aluminum heads and overhead valves, with identical bore and stroke of and , respectively. Typical power ratings varied from . After Walter concentrated on the turbine powerplants only, the production of piston engines has been transferred to the Avia company that further developed the family, bringing fuel injection, as the Avia M-137 and M-337. Nowadays the smallest of the family, the four-cylinder carburetted Minor, is produced by a small company in the Czech Republic, while the M337 was available from the LOM Prague.

Boeing L-15 Scout
The Boeing L-15 Scout or YL-15 was a small, piston engine liaison aircraft built by Boeing in very small numbers after World War II. It was a short take-off and landing ( STOL) aircraft powered by a 125 hp Lycoming engine. The L-15 was an attempt by Boeing to expand its product line as World War II drew to a close, and Boeing's production of combat aircraft declined. Boeing decided against marketing the L-15 as a general aviation aircraft, and the twelve that were produced went to the United States Army for testing, then were transferred to the United States Fish and Wildlife Service in Alaska for various duties. Design The scout was a conventional geared aircraft that was also tested on ski and float gear. The unique fuselage tapered sharply behind the pilot similar to a helicopter fuselage, with a high-mounted boom supporting the tail surfaces. The original design included a single vertical stabilizer, but two small downward-mounted stabilizers were used on production model ...

Miles M
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the British Commonwealth and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile, such as the nautical mile (now exactly), the Italian mile (roughly ), and the Chinese mile (now exactly). The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in Elizabethan-era England meant that the statute mile was made equivalent to or in 1593. This form of the mile then spread across the British Empire, some successor states of which conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s Czechoslovakian Military Reconnaissance Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...
