SZD-C Żuraw
The SZD-C Żuraw ('' Szybowcowy Zakład Doświadczalny'' - Glider Experimental Works), also designated as IS-C is a two-seat training and aerobatic glider aircraft, built in Poland from 1952, a copy of the German DFS Kranich II. Development World War II destroyed Polish pre-war gliders, but after the war, Poland was left in the possession of incomplete drawings and documentation for the DFS Kranich II, as well as gliders left behind by the retreating German forces. To provide the Polish Aero Club with a viable two-seat trainer, the SZD-C Żuraw II was developed from the Hans Jacobs-designed DFS Kranich II, adapted for Polish production by J. Niespał and A. Kokot. The name ''żuraw'' was a translation of ''Kranich'' and means '' crane''. The Kranich was one of the best two-seater pre-war gliders, used to set many records. The first flight of the Żuraw took place on 22 April 1952. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource.

Polish Aero Club
The Polish Aero Club (''Aeroklub Polski'', AP) is the Polish central association of persons practising air sports or recreational flying. It was founded in 1921 and is a member of the Fédération Aéronautique Internationale. It has a headquarters in Warsaw. History Aviation organizations could be founded in Poland only after regaining independence in 1918. The first such organization was Aeroklub Polski w Poznaniu (''PAC in Poznań''), founded on 30 October 1919 and admitted to the FAI in 1920. In June 1920 there was founded Aeroklub Polski w Warszawie (''PAC in Warsaw''). On 18 January 1921 both Aero Clubs formed a central federation Aeroklub Rzeczypospolitej Polskiej (ARP; ''Aero Club of the Polish Republic''). By 1939, there were created several other regional aero clubs, including some university aero clubs. Before the World War II, members of the ARP took active part in world's aviation sports. The first major international event was the Challenge 1930 touring planes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950s Polish Sailplanes
Year 195 ( CXCV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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 has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger. The Roman province of Mesopotamia rises in revolt with Parthian support. Severus marches to Mesopotamia to battle the Parthians. * The Roman province of Syria is divided and the role of Antioch is diminished. The Romans annex the Syrian cities of Edessa and Nisibis.

Polish Aviation Museum
The Polish Aviation Museum () is a large museum of historic aircraft and aircraft engines in Kraków, Poland. It is located at the site of the no-longer functional Kraków-Rakowice-Czyżyny Airport. This airfield, established by Austria-Hungary in 1912, is one of the oldest in the world. The museum opened in 1964, after the airfield closed in 1963. It was listed among the world's best aviation museums by CNN. For the first half century of its existence the museum used four hangars of the former airfield to display its exhibits. These buildings were not originally designed for this purpose and suffered from various inadequacies, notably insufficient heating in winter. The situation improved when a new main building for the museum opened on 18 September 2010. Book imprint The Museum also functions as a publishing house, publishing venue, in particular for dozens of books, photo albums, memoirs and brochures devoted to aviation history, including the subject of Polis ...

Air Brake (aircraft)
In aeronautics, air brakes, or speed brakes, are a type of flight control surface used on an aircraft to increase the drag on the aircraft. When extended into the airstream, air brakes cause an increase in the drag on the aircraft. When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag. Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, whereas spoilers reduce the lift-to-drag ratio and require a higher angle of attack to maintain lift, resulting in a higher stall speed. However, flight spoilers are routinely referred to as "speed brakes" on transport aircraft by pilots and manufacturers, despite significantly reducing lift. History In the early decades of powered flight, air brakes were flaps mounted on the wings. They were manually controlled by a lever in the cockpit, and mechanical linkages to the air brake. Another early type of air brake, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrzeszcz
Wrzeszcz (pronounced , ; ) is one of the boroughs of the Northern Polish city of Gdańsk. With a population of more than 65,000 in an area of (population density 6,622), Wrzeszcz is the most populous part of Gdańsk. History The current name Wrzeszcz comes from the old name of the area – ''Wrzost'', which derives from ''wrzos'', a Polish and Kashubian word for heather. The area of modern Wrzeszcz used to be forest and fields of heather. In modern Polish, the literal meaning of the word "wrzeszcz" is the second-person singular imperative form of "wrzeszczeć", meaning 'to scream/shout/yell', but this is not related to the etymology of this place name. Historical sources mention ''Vriezst'' in 1263 AD and Vriest 1283 as a place of a mill and by the end of the 13th century the Cistercian Monks of Oliwa owned four or five water mills on the Strieß ( Strzyża), the creek running through Wrzeszcz. Vriest is Low German as well as Dutch language word meaning ''frost''. In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crane (bird)
Cranes are a type of large bird with long legs and necks in the Family (biology), biological family Gruidae of the Order (biology), order Gruiformes. The family has 15 species placed in four genera which are ''Antigone (genus), Antigone'', ''Balearica'', ''Siberian crane, Leucogeranus'', and ''Grus (genus), Grus''. They are large birds with long necks and legs, a tapering form, and long secondary feathers on the wing that project over the tail. Most species have muted gray or white plumages, marked with black, and red bare patches on the face, but the crowned cranes of the genus ''Balearica'' have vibrantly-coloured wings and golden "crowns" of feathers. Cranes fly with their necks extended outwards instead of bent into an S-shape and their long legs outstretched. Cranes live on most continents, with the exception of Antarctica and South America. Some species and populations of cranes bird migration, migrate over long distances; others do not migrate at all. Cranes are solitary du ...

Hans Jacobs
Hans Jacobs (30 April 1907 in Hamburg – 24 October 1994) was a German sailplane designer and pioneer. He had been taught sailplane design by Alexander Lippisch, designer of many gliders during the 1920s and the 1930s. As the head of the ''Deutsche Forschungsanstalt für Segelflug'' (DFS - German Research Institute for Sailplane Flight) at Darmstadt in the years before World War II, he was responsible for a number of highly successful designs, including the DFS Rhönsperber, DFS Rhönadler, DFS Habicht, DFS Weihe, DFS Kranich, and the DFS 230 assault glider. Hans also designed a glider-seaplane, the "Sea Eagle", test flown by Hanna Reitsch.Reitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, In 1936, Hans developed self-operating dive brakes, on the upper and lower surface of each wing, for gliders. He designed the DFS 230 used in the Battle of Fort Eben-Emael. The DFS Olympia Meise was selected in 1939 as the glider for the 1940 Su ...

Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose gliding flight, free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by Motor glider, self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit lift (soaring), meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such a ...

Szybowcowy Zakład Doświadczalny
Szybowcowy Zakład Doświadczalny (SZD), ''Glider Experimental Works'' was a glider aircraft, glider design and research centre of the Polish aerospace industry after World War II, located in Bielsko-Biała. Through its history it underwent many organizational and name changes, among others in 1946-1948 it was ''Instytut Szybownictwa''. After 1969 it existed under other names, but an abbreviation SZD continued to be used on designs. The SZD gliders themselves were produced in the production centre in Bielsko-Biała, organized around the SZD (from 1990s named PZL-Bielsko), and by several other works of the state aerospace industry and didn't bear specific manufacturer's names. Beginnings Just after World War II, which destroyed most of Polish pre-war gliders and - more importantly - their production blueprints,http://www.samolotypolskie.pl on SZD, op.cit. the Main Scouts' Gliding Centre (''Centralny Harcerski Ośrodek Szybowcowy'') was created in Bielsko-Biała in May 1945, by t ...
