LWD Żak
The LWD Żak was a Polish touring and trainer aircraft of the late 1940s, designed in the LWD and built in a short series. Design and development The Żak (old-fashioned "student") was designed in the Lotnicze Warsztaty Doświadczalne (LWD, ''Aviation Experimental Workshops'') in Łódź, directed by Tadeusz Sołtyk in 1946, as one of the first Polish post-war aircraft. It was a light low-wing cantilever monoplane of a mixed construction, with a crew of two, sitting side by side, and fixed conventional landing gear. The first prototype Żak-1 was first flown on March 23, 1947. It was powered by the Czechoslovak 65 hp straight engine Walter Mikron III and carried markings SP-AAC. The second prototype Żak-2 was powered by the 65 hp flat engine Continental A-65 and had an open cockpit. It was flown on November 27, 1947, and carried markings SP-AAE. The design appeared successful and the Ministry of Communication ordered a series of 10 aircraft. They were to be powered by ...

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 ...

Aeroklub Polski
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 conte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s Polish Civil Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) 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 * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

RWD-21
The RWD 16bis and RWD 21 were Polish two-seat low-wing touring and sports planes of the late 1930s, constructed by the RWD bureau, sharing the same construction, main difference of the RWD 21 being a stronger engine. Development The RWD 16bis was designed in 1938 by Andrzej Anczutin of the RWD bureau as a light and economical touring and sports plane, utilizing the experience from an unsuccessful earlier design RWD 16. In spite of the designation, the RWD 16bis design was new, only partly basing on the RWD 16 construction. On contrary, it appeared a successful design, with good handling and performance and ease of flying. It was a wooden low-wing monoplane, with two seats side-by-side in a closed cockpit. The first prototype was built and first flown in June–July 1938 (registration SP-BNM) followed by the second prototype (SP-BPC). Both were powered by a Polish-designed 63 hp Avia 3 straight engine. In series, a 62 hp Walter Mikron II straight engine was expected. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight Engine
The straight or inline engine is an internal combustion engine with all cylinders aligned in one row and having no offset. Usually found in four, six and eight cylinder configurations, they have been used in automobiles, locomotives and aircraft, although the term in-line has a broader meaning when applied to aircraft engines, see Inline engine (aviation). Design A straight engine is considerably easier to build than an otherwise equivalent horizontally opposed or V engine, because both the cylinder bank and crankshaft can be milled from a single metal casting, and it requires fewer cylinder heads and camshafts. In-line engines are also smaller in overall physical dimensions than designs such as the radial, and can be mounted in any direction. Straight configurations are simpler than their V-shaped counterparts. Although six-cylinder engines are inherently balanced, the four-cylinder models are inherently off balance and rough, unlike 90-degree V fours and horizontally oppos ...

Kraków
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. The city has grown from a Stone Age settlement to Poland's second-most-important city. It began as a hamlet on Wawel Hill and was reported by Ibrahim Ibn Yakoub, a merchant from Cordoba, as a busy trading centre of Central Europe in 985. With the establishment of new universities and cultural venues at the emergence of the Second Polish Republic in 1918 and throughout the 20th century, Kraków reaffirmed its role as a major national academic and a ...

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] |
Polikarpov Po-2
The Polikarpov Po-2 (also U-2, for its initial ''uchebnyy'', 'training', role as a flight instruction aircraft) served as an all-weather multirole Soviet biplane, nicknamed ''Kukuruznik'' (russian: Кукурузник,Gunston 1995, p. 292. NATO reporting name "Mule".)
