Plage I Laśkiewicz
Plage i Laśkiewicz (Plage & Laśkiewicz) was the first Polish aerospace manufacturer, located in Lublin and manufacturing aircraft under Lublin name. Full name was: ''Zakłady Mechaniczne E. Plage i T. Laśkiewicz'' – Mechanical Works E. Plage & T. Laśkiewicz. The factory produced aircraft between 1920 and 1935, when it was nationalized as the Lubelska Wytwórnia Samolotów. History Beginnings and license production The company was founded in 1860 as Fabryka Wyrobów Miedziowych, a mechanical workshop specializing in the manufacture of copper products. However, by 1919 it had been renamed Plage i Laśkiewicz and that year it started producing aircraft. On February 17, 1920, the Polish government ordered a licence production of Italian fighters Ansaldo A.1 Balilla and light bombers Ansaldo A.300 in Plage & Laśkiewicz. The first Polish A.300 was flown on June 14, 1921. However, due to the lack of experience, the quality of produced aircraft was low, and there were numer ...

Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space A ...

Lublin Rxiii
Lublin is the ninth-largest city in Poland and the second-largest city of historical Lesser Poland. It is the capital and the centre of Lublin Voivodeship with a population of 336,339 (December 2021). Lublin is the largest Polish city east of the Vistula River, located southeast of Warsaw. One of the events that greatly contributed to the city's development was the Polish–Lithuanian Union of Krewo in 1385. Lublin thrived as a centre of trade and commerce due to its strategic location on the route between Vilnius and Kraków; the inhabitants had the privilege of free trade in the Grand Duchy of Lithuania. The Lublin Parliament session of 1569 led to the creation of a real union between the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, thus creating the Polish–Lithuanian Commonwealth. Lublin witnessed the early stages of the Reformation in the 16th century. A Calvinist congregation was founded and groups of radical Arians appeared in the city, making it an ...

Ralf-Stetysz
Ralf-Stetysz () was the marque of one of the earliest Polish car manufacturers begun in France and transferred to Poland in the 1920s. It was formed in 1924, when Count Stefan Tyszkiewicz, an inventor and mechanical engineer, started a small automotive firm "Automobiles Ralf Stetysz" in Boulogne-Billancourt near Paris. The name was an acronym in Polish of the name "Rolniczo Automobilowo-Lotnicza Fabryka Stefana Tyszkiewicza" - "Agricultural-Automobile-Aero Factory of Stefan Tyszkiewicz"). Tyszkiewicz designed several prototypes, drawing heavily on contemporary French car designs, but better suited for the dismal Polish roads of the time. A single prototype was completed, with a strengthened suspension, a locking differential and a powerful Continental engine. It was presented at the 1926 and 1927 Paris Motor Show, where it received positive reviews as a good "colonial car". The prototype proved interesting and in 1927 Tyszkiewicz was able to secure cooperation with the Warsaw-bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ursus Tractor Factory
Ursus SA (often stylized URSUS SA) was a Polish agricultural machinery manufacturer, headquartered in Lublin, Poland. The company was founded in Warsaw in 1893, and holds a prominent place in Polish tractor production history. It has also carried out some production of trolleybuses in a joint venture with the Ukrainian manufacturer Bogdan, and manufactures buses, coaches, and trolleybuses in a joint venture with Polish manufacturer AMZ Kutno under the name Ursus Bus. The name means 'bear' in Latin. History Early history The Ursus Factory was founded in 1893 on 15 Sienna Street, Warsaw, by three engineers and four businessmen. It was first named: ''Towarzystwo Udziałowe Specyalnej Fabryki Armatur'' (Company of a Special Factory of Fixture), later with an addition: ''i Motorów'' (and Motors). It began producing valves and pumps, intended first of all to Tsarist Russian market, as Poland had been partitioned by that time and most of its territory was annexed by Russia. ...

Lublin R-XX
The Lublin R-XX was the Polish torpedo bomber floatplane, designed in the early 1930s in the Plage i Laśkiewicz factory in Lublin. It remained a prototype. Design and development In 1930 the Polish Ministry of Defence announced a contest for a torpedo-bomber floatplane for the Polish Navy. Plage i Laśkiewicz works proposed first a floatplane variant F.VIIW of a licence-built bomber (developed from a passenger plane) Fokker F.VII, but it was not built. It also proposed a floatplane variant of single-engined Lublin R-VIII biplane bomber. In a course, three R-VIIIs were converted to floatplanes and given to the Navy, but they did not meet all demands, for they were obsolete, slow and could not carry torpedoes. Then Plage i Laśkiewicz proposed quite modern twin-engined plane Lublin R-XX, the main designer of which was Jerzy Rudlicki. The last design won the contest in 1932, besting PZL-18 and PWS-62 designs, and a prototype was ordered. It was initially planned to build a series ...

Air Ambulance
Air medical services are the use of aircraft, including both fixed-wing aircraft and helicopters to provide various kinds of urgent medical care, especially prehospital, emergency and critical care to patients during aeromedical evacuation and rescue operations. History During World War I, air transport was used to provide medical evacuation – either from frontline areas or the battlefield itself. In 1928, in Australia, John Flynn founded the Flying Doctor Service (later the Royal Flying Doctor Service), to provide a wide range of medical services to civilians in remote areas; these included from routine consultations with travelling general practitioners, to air ambulance evacuations and other emergency medical services. Fixed wing military air ambulances came into regular use during World War II. Helicopters became more commonly used for such purposes during the Korean and Vietnam wars. Later, helicopters were introduced to civilian health care, especially for sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lublin R-XVI
The Lublin R-XVI was a Polish passenger and air ambulance aircraft, designed in the 1930s in the Plage i Laśkiewicz factory in Lublin and built in a small series. Design and development The Lublin R-XVI was conceived as a small 4-seater passenger plane, ordered by the Polish Ministry of Communications. It was a development of an unsuccessful Lublin R-XI design. The main designer was Jerzy Rudlicki. The new plane was lighter and introduced a trapezoid-shaped wing instead of an elliptical one. Both designs were partly modeled on a construction of Fokker F.VII, produced under licence by Plage i Laśkiewicz. The first prototype was flown in February 1932. In the same year it was evaluated by the LOT Polish Airlines, flying 12,500 km. The R-XVI took part in a contest for a successor of Junkers F.13 planes in LOT airlines. The contest was won by PWS-24, because the construction of the R-XVI had to be strengthened, what reduced its payload to 546 kg. This had to reduce it ...

V-tail
The V-tail or ''vee-tail'' (sometimes called a butterfly tail or Rudlicki's V-tailGudmundsson S. (2013). "General Aviation Aircraft Design: Applied Methods and Procedures" (Reprint). Butterworth-Heinemann. p. 489. , 9780123973290) of an aircraft is an unconventional arrangement of the tail control surfaces that replaces the traditional vertical and horizontal surfaces with two surfaces set in a V-shaped configuration. It is not widely used in aircraft design. The aft edge of each twin surface is a hinged control surface called a ruddervator, which combines the functions of both a Rudder#Aircraft rudders, rudder and Elevator (aeronautics), elevator. History The V-tail was invented in 1930 by Polish engineer Jerzy Rudlicki and was tested for the first time on a Hanriot HD.28 trainer, modified by Poland, Polish aerospace manufacturer Plage i Laśkiewicz, Plage and Laśkiewicz in the summer of 1931. Variants The X-shaped tail surfaces of the experimental Lockheed XFV were essential ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lublin R-XIII
The Lublin R-XIII was the Polish army cooperation plane (observation and liaison plane), designed in the early-1930s in the Plage i Laśkiewicz factory in Lublin. It was the main army cooperation plane in the Invasion of Poland. Its variant Lublin R-XIV was a military trainer aircraft. Design and development In 1927, the Polish aviation authorities announced a contest for an army-cooperation plane (in Polish: ''samolot towarzyszący'', literally: "accompanying plane"). In Polish doctrine it was a close reconnaissance, observation and liaison aircraft, operating from casual airfields, providing big Army land units with information about the enemy. The PZL state factory proposed the PZL Ł-2, built in a series of 25 aircraft, while private factory Plage i Laśkiewicz in Lublin proposed the Lublin R-X, designed by Jerzy Rudlicki. It was flown on February 1, 1929. Five aircraft were built for the Air Force as R-Xa, and one was built as a long-distance sports plane. The third com ...

Trainer Aircraft
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that the pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Polish Air Force
The Polish Air Force () is the aerial warfare Military branch, branch of the Polish Armed Forces. Until July 2004 it was officially known as ''Wojska Lotnicze i Obrony Powietrznej'' (). In 2014 it consisted of roughly 26,000 military personnel and about 475 aircraft, distributed among ten bases throughout Poland. The Polish Air Force can trace its origins to the second half of 1917 and was officially established in the months following the end of World War I in 1918. During the invasion of Poland by Nazi Germany in 1939, 70% of its aircraft were destroyed. Most pilots, after the Soviet invasion of Poland on 17 September, escaped via Romania and Hungary to continue fighting throughout World War II in allied air forces, first in France, then in Britain, and later also the Soviet Union. History Polish Air Force backline Origins Military aviation in Poland started even before the officially recognised date of regaining independence (11 November 1918).
