Mráz Bonzo
The Mráz M-3 Bonzo was a light aircraft built in Czechoslovakia in 1948 as a further development in the family of light aircraft that had commenced with the M-1 Sokol. Design and development After the end of the Second World War, the Czechoslovak company Beneš-Mráz, which had been a successful producer of light aircraft prior to the war, came under the control of Automobilov Zavody, with Beneš-Mráz's Choceň factory being renamed Orlican Narodny Podnik in 1946. Mráz's designer Zdeněk Rublič, who had secretly designed the Mráz Sokol, which first flew in 1946, during the war, envisioned a series of related light aircraft, including a two-seat trainer, which became the M-2 Skaut, and a four-seater, the M-3 Bonzo. The Bonzo was based on the Sokol airframe, but with a redesigned wing and substantial changes to the fuselage. These included lengthening it to allow for the addition of a fourth seat, reducing the height of the rear fuselage to allow for a new cabin with all-a ...

1948 Czechoslovak Coup D'état
In late February 1948, the Communist Party of Czechoslovakia (KSČ), with Soviet backing, assumed undisputed control over the government of Czechoslovakia through a coup d'état. It marked the beginning of four decades of the party's rule in the country. The KSČ enjoyed a period of popularity following the reestablishment of pre-war Czechoslovakia. After a successful performance during the 1946 parliamentary election, party leader Klement Gottwald became prime minister of a coalition government at the behest of President Edvard Beneš. By summer 1947, however, the KSČ's popularity had significantly dwindled, and the party was expected to be soundly defeated in the May 1948 elections. This, along with the electoral failures of the French and Italian communist parties, prompted Joseph Stalin to harden his approach and order Gottwald to seize power. On 21 February 1948, twelve non-Communist ministers resigned in protest. They objected to Gottwald's refusal to stop packing th ...

Aircraft First Flown In 1948
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-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 wings. 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, ...

Beneš-Mráz Aircraft
inž. P. Beneš a inž. J. Mráz, továrna na letadla was a Czechoslovak aircraft manufacturer of the 1930s. History Beneš-Mráz was established at Choceň by Pavel Beneš and Jaroslav Mráz on 1 Apr 1935 and manufactured a series of light aircraft of their own design until the Nazi-German occupation. In 1939/40, the company was renamed ''Ing. J. Mráz, továrna na letadla'' - ''Ing. J. Mráz, Flugzeugfabrik''. During the war, the factory was used to produce Fieseler Fi 156 "Storch"s and DFS Kranich training gliders for the German Luftwaffe. Following the war, the company was reconstituted as Ing. J.

1940s Czechoslovak Civil Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday 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 * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

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.

Svazarm
Svazarm or Union for Cooperation with the Army (Czech: Svaz pro spolupráci s armádou / Svazarm, Slovak: Zväz pre spoluprácu s armádou / Zväzarm) was, in Communist Czechoslovakia, the largest "paramilitary" organisation, although many of the activities that Svazarm provided for its members were more reminiscent of a Boy Scout movement than of a regimented paramilitary group. Established in 1951, the Svazarm was an almost exact copy of the Soviet Union's DOSAAF, however, with massively scaled down maritime activities as Czechoslovakia was landlocked. However, canoeing was still a popular activity. In 1985, it had about one million members, 60% of whom were under 35 years of age. Activities The activities the Svazarm provided were extremely diverse, ranging from medical training to dog training. Dog lovers would be instructed in the training and breeding of dogs suitable for military purposes, especially German Shepherds. Shortwave radio operation was another popular activit ...

Air-taxi
An air taxi is a small commercial aircraft that makes short flights on demand. History The concept of air taxis existed as early as the 1910s. This concept goes back as early as 1917 with Glenn Curtiss’ prototype, the auto-plane. Furthermore, during the 1920s to the late 1950s, various inventors created their own prototypes. Such inventors included Henry Ford, Waldo Waterman, and Moulton “Molt” Taylor. However, each of these projects faced challenges which included crashes, lack of funding, or technical difficulties. After all this experimentation and challenges faced, the urban air mobility industry had shifted focus on “improving safety and enhancing economic and operational efficiency of vertical flight". The next phase from the 1950s to the late 1980s included urban air mobility services through the use of helicopters within major cities such as Los Angeles, San Francisco, and New York; however, the challenges of fuel costs and safety have made it difficult to comm ...

Aero 45
The Aero 45 was a twin piston-engined civil utility aircraft produced in Czechoslovakia after World War II. Aero Vodochody produced the aircraft in 1947–1951, after which the Let Kunovice rolled out these planes until 1961. In 1958 the Ae-45S became the first Czechoslovak plane to cross the Atlantic Ocean. It was the first product of the nation's postwar aviation industry and proved a great success, with many of the 590 produced being exported. The aircraft was developed into other variants, including the "Super Aero" and Ae 145. Design and development Development began 1946 and was accomplished by the technical designers Jiři Bouzek, Ondřej Němec and František Vik. The design bears a superficial resemblance, when viewed nose-on, to the much larger German Siebel Si 204 which, among other German aircraft were produced in Czechoslovakia while under German occupation. The prototype (registered OK-BCA) flew for the first time on 21 July 1947 and the second, registered OK-CD ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
