Beneš-Mráz Be-50 Beta-Minor
The Beneš-Mráz Be-50 Beta-Minor was a light airplane manufactured in Czechoslovakia shortly before World War II. Design and development First flown in 1935, it was a low-wing cantilever monoplane of wooden construction, with tandem open cockpits and fixed tailwheel undercarriage. The aircraft proved popular with Czechoslovakia's aeroclubs and was successful in international competitions. In 1937, the designers created a modernised version, the Be-51, which featured a reduced wingspan and fully enclosed cockpits. A final variant, the Be-52 Beta-Major retained the Be-50's open cockpits but featured improved aerodynamics and a more powerful Walter Major engine. Operational history Like other Czechoslovakian aircraft, all available machines were impressed into Air Force service at the outbreak of war. Several Be-51s survived to be used by the ''Luftwaffe'' as liaison aircraft and trainers during the occupation. In 2015, replica of Be-50 started operating. It crashed at airshow ...

1930s Czechoslovak Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

Walter Minor
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 Motors, 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.

Air Force Of The Independent State Of Croatia
The Air Force of the Independent State of Croatia (; ZNDH), was the air force of the Independent State of Croatia (NDH), a puppet state established with the support of the Axis Powers on the territory of the Kingdom of Yugoslavia during World War II. The ZNDH was founded under Nazi Germany, German authority in April 1941, following the German-led Axis invasion of Yugoslavia. Although it could not be considered a large air arm in the wider context of World War II, the ZNDH nonetheless had on its charge at one time or another some 650 aircraft between April 1941 and May 1945, as well as anti-aircraft and paratroop units. From humble beginnings in 1941, the ZNDH was still providing some measure of air-support (fighter, attack and transport) until the last days of World War II in Europe. The ZNDH maintained a flying training school equipped with gliders and trainers, originally at Rajlovac airfield near Sarajevo and then at Velika Gorica and Pleso airfields in Zagreb.

Aerobatic
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aeroplane" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear ...

Piston Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more Reciprocating motion, reciprocating pistons to convert high temperature and high pressure into a Circular motion, rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition engine, spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition engine, compression-ignition (CI) engine, where the air within the cylinder is compressed, Adiabatic process, thus heating it, so that the heated air ignites fuel that is injected diesel engine, then or hot-bulb engine, earlier.''Thermodynamics: An Engineering Approach'' by Yunus A.
