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 mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Polish Aero Club
Aeroklub Polski (AP; ''Polish Aero Club'') 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 contes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950s Polish Sailplanes
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''). 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.

Polish Aviation Museum
The Polish Aviation Museum ( pl, Muzeum Lotnictwa Polskiego w Krakowie) 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. Has been scored as eighth world's best aviation museum 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. Collection The collection consists of over 200 aircraft as of 2005. Several of the aircraft displayed are unique on the world scale, including sailplanes and some 100 ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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. Introduction An air brake is a part of an aircraft. When extended into the airstream, it causes an increase in the drag on the aircraft. When not in use, it conforms to the local streamlined profile of the aircraft in order to help minimise the drag. 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. An early type of air brake, developed in 1931, was fitted to the aircraft wing support struts. In 1936, Hans Jacobs, who headed Nazi Germany's '' ...

Wrzeszcz
Wrzeszcz (pronounced , german: Langfuhr; csb, Wrzészcz) is one of the boroughs of the Northern Poland, 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 csb, wrzos word for Ericaceae, heather. The area of modern Wrzeszcz used to be forest and fields of heather. 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 Cistercians, 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 1412 AD, this suburban village was granted to Danzig city councillor Gerd von der Beke, an ally of the Teutonic Knights. The place was known as Langfuhr in the G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crane (bird)
Cranes are a family, the Gruidae, of large, long-legged, and long-necked birds in the group Gruiformes. The 15 species of cranes are placed in three genera, ''Antigone'', ''Balearica'', and '' Grus''. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes live on most continents, with the exception of Antarctica and South America. They are opportunistic feeders that change their diets according to the season and their own nutrient requirements. They eat a range of items from small rodents, eggs of birds, fish, amphibians, and insects to grain and berries. Cranes construct platform nests in shallow water, and typically lay two eggs at a time. Both parents help to rear the young, which remain with them until the next breeding season. Some species and populations of cranes migrate over long distances; others do not migrate at all. Cranes are solitary during the breeding season, occurring in pairs, but during the nonbreeding se ...

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 Summer Oly ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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 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 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 as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 th ...
