BŻ-1 GIL
The BŻ-1 GIL was the first Polish experimental helicopter, constructed in 1950. Developed by the Main Aviation Institute (Warsaw), the only constructed GIL saw service until 1960 when it was irreparably damaged and subsequently decommissioned. The prototype aircraft currently resides at the Polish Aviation Museum. Design and development The helicopter was designed at the research institute ''Główny Instytut Lotnictwa'' - Main Aviation Institute in Warsaw, from an initiative of Zbigniew Brzoska. It was a difficult task, because Polish aviation industry was entirely destroyed during World War II. In addition, the institute principal Władysław Fiszdon was the only person in a team, who had ever seen a helicopter (Sikorsky R-4 in England).Glass 2005, pp. 44–45. Despite severe material shortages, work on experimental design started in 1948, and the main designer became Bronisław Żurakowski (brother of test pilot Janusz Żurakowski), who designed a rotor and control system. ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Zündapp
Zündapp (a.k.a. Zuendapp) was a major German motorcycle manufacturer founded in 1917 in Nuremberg by Fritz Neumeyer, together with the Friedrich Krupp AG and the machine tool manufacturer Thiel under the name "Zünder- und Apparatebau G.m.b.H." as a producer of detonators (Zünder- und Apparatebau is German for Igniter and Apparatus). In 1919, as the demand for weapons parts declined after World War I, Neumeyer became the sole proprietor of the company, and two years later he diversified into the construction of motorcycles. Following World War II, Zündapp expanded into the microcar, moped and scooter markets. The company collapsed in 1984. Early history: 1919–45 The first Zündapp motorcycle was the model Z22 in 1921. This was the ''Motorrad für Jedermann'' ("motorcycle for everyone"), a simple, reliable design that was produced in large series. Zündapp's history of heavy motorcycles began in 1933 with the K-series. The "K" refers to the type of drivetrain that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita'').

Vought-Sikorsky 300
The Vought-Sikorsky VS-300 (or S-46) is an American single-engine helicopter designed by Igor Sikorsky. It had a single three-blade rotor originally powered by a 75 horsepower (56 Watt#Kilowatt, kW) engine. The first "free" flight of the VS-300 was on 13 May 1940.Munson 1968, p. 111. The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. With Float (nautical), floats attached, it became the first practical amphibious helicopter. Design and development Igor Sikorsky's quest for a practical helicopter began in 1938, when as the Engineering Manager of the Vought-Sikorsky Division of United Aircraft Corporation, he was able to convince the directors of United Aircraft that his years of study and research into rotary-wing flight problems would lead to a breakthrough. His first experimental machine, the VS-300, was test flown by Sikorsky on 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gazda Helicospeeder
The Gazda Helicospeeder was an American-built single-seat single-rotor helicopter of the 1940s. Development The Helicospeeder was designed by Antoine Gazda of Wakefield, Rhode Island in 1946. It was specified to carry one person and publicity releases claimed an ultimate goal of a maximum airspeed. One example of the initial version was completed. The Model 100 Helicospeeder was developed in 1947, again with a single seat. It was of all-aluminium construction and was powered by a Continental A-75 engine. One example was completed. Operational history The designer/constructor carried out test flights and a more modest actual speed of was reached. Production examples were expected to sell for 5000 US Dollars, but no firm sales were made. Variants Antoine Gazda planned to build the Model 101, which was intended to accommodate two persons, but no record of its completion has been found.

Kraków (), or Cracow, is the second-largest and one of the oldest cities in Poland. Situated on the Vistula River in Lesser Poland Voivodeship, the city dates back to the seventh century. Kraków was the official capital of Poland until 1596 and has traditionally been one of the leading centres of Polish academic, economic, cultural and artistic life. Cited as one of Europe's most beautiful cities, its Old Town with Wawel Royal Castle was declared a UNESCO World Heritage Site in 1978, one of the first 12 sites granted the status.

Mil Mi-1
The Mil Mi-1 (USAF/DoD reporting name "Type 32", NATO reporting name "Hare") was a Soviet three- or four-seat light utility helicopter. It was the first Soviet helicopter to enter serial production. It is powered by one Ivchenko AI-26V radial piston engine. It entered service in 1950 and was first seen on the 1951 Soviet Aviation Day, Tushino and was produced for 16 years. More than 1,000 were built in the USSR and 1,594 in Poland, as SM-1. Development Mikhail Mil began work on rotary-winged aircraft before 1930, but the Mi-1, his first production helicopter, was begun in 1946, under a designation EG-1. In 1947 Mil became a head of OKB-4 design bureau in Tushino, and works were intensified. A final design was named GM-1 (for ''Gyelikopter Mila'', Mil's Helicopter). Soviet engineers tried to create a completely original design. So, they made a rotor hub with spaced vertical and horizontal hinges. This design increased the efficiency of helicopter control and was much simpler t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
