RWD-8
The RWD 8 was a Polish parasol wing monoplane trainer aircraft produced by RWD. It was used from 1934 to 1939 by the Polish Air Force and civilian aviation. Development The RWD 8 was designed in response to a Polish Air Force requirement in 1931 for a basic trainer aircraft. It was designed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki. The first prototype (registration SP-AKL), was flown in early 1933. It won the contest for the new Polish military trainer, against the PZL-5bis and Bartel BM-4h biplanes. It was considered a very stable and well-handling aircraft. Since the DWL (''Doświadczalne Warsztaty Lotnicze'') workshops – a manufacturer of RWD designs – had limited production capability, the Polish military decided to produce the aircraft in a nationalized factory PWS (''Podlaska Wytwórnia Samolotów''). DWL gave away the licence free of charge, only for covering design costs. PWS produced aircraft for both military and civilian avia ...

RWD (aircraft Manufacturer)
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym. History They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (''Sekcja Lotnicza Koła Mechaników Studentów''), where they manufactured their first designs. From 1926 they designed several aircraft alone ( Drzewiecki JD-2 and WR-1), in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Okęcie aerodrome, today's Warsaw International Airport, founded by the LOPP paramilitary organization. ...

PZL-5
The PZL-5 was a Polish two-seat touring and sports aircraft of 1930 constructed and produced by the PZL. Design and development The aircraft was designed in 1929 by an amateur designer Władysław Kozłowski. It was a wooden biplane, similar to de Havilland Gipsy Moth. The PZL State Aviation Works in Warsaw took over the design, searching for an aircraft to participate in a contest for a trainer aircraft, announced by the LOPP paramilitary organization (Air- and Anti-Gas Defense League). Kozłowski worked out a documentation, with a help of PZL bureau and fitted the example with a more powerful 100 hp Gipsy I engine, instead of a planned 85 hp version. The first prototype of PZL-5 was built and flown in May 1930, followed by two pre-series aircraft in June 1930, built on the factory's initiative specially for the International Touring Competition 1930 (''Challenge'') (registration SP-ACW and SP-ACX).Glass 1977, pp. 222–224. After trials, the design was modified, rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish Air Force
The Polish Air Force ( pl, Siły Powietrzne, , Air Forces) is the aerial warfare 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 16,425 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 September 17, 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 Origins Military aviation in Poland started even before the officially recognised date of regaining independence (11 November 1918). The very first independent units of th ...

Bartel BM-4
The Bartel BM.4 was a Polish biplane primary trainer aircraft used from 1929 to 1939 by the Polish Air Force and Polish civilian aviation, manufactured in the Samolot factory in Poznań. It was the first plane of Polish design put into production. Design and development The aircraft was designed by Ryszard Bartel in the Samolot factory in Poznań. It was a development of the Bartel BM.2, which did not advance beyond the prototype stage. Thanks to a lower weight than the BM.2, it could use lower-powered engines, so its performance was actually improved. Its performance was also superior to the Hanriot H.28, used by the Poles and licence-built by Samolot. The BM.4 prototype was flown on 20 December 1927 in Poznań. It had good handling and stability and was resistant to spinning. A distinguishing feature of all Bartels was an upper wing of a shorter span, because lower and upper wing halves were interchangeable (i.e. the lower wingspan included the width of the fuselage).

Podlaska Wytwórnia Samolotów
Podlaska Wytwórnia Samolotów (PWS) - ''Podlasie Aircraft Factory'' - was a Polish aerospace manufacturer between 1923 and 1939, located in Biała Podlaska. History Podlaska Wytwórnia Samolotów SA was created in 1923. The first aircraft produced were 35 Potez 15 bombers for the Polish Air Force, under the French licence, built from 1925.Glass, A. (1977), p.22-25 By 1929 the works had produced 155 Potez 27 and 150 Potez 25, under French licence, and 50 PWS-A fighters, which was the Czech Avia BH-33 built under licence. It also produced 50 Bartel BM-4 trainers in 1931, designed by Samolot. In 1925, a design office was established which included, among others, Stefan Cywiński, Zbysław Ciołkosz, August Bobek-Zdaniewski. Despite a large number of prototypes, few were produced in series. The first aircraft of their own design to be mass-produced was the PWS-10 fighter of 1930 of which 80 examples were built. Smaller production runs of the PWS-14 trainer and the PWS-24 pass ...

Stanisław Wigura
Stanisław Wigura (9 April 1901 – 11 September 1932) was a Polish aircraft designer and aviator, co-founder of the RWD aircraft construction team and lecturer at the Warsaw University of Technology. Along with Franciszek Żwirko, he won the international air contest Challenge 1932. He was born in Warsaw. In his youth he was interested in mechanics and aviation, and he was also a Boy Scout. In 1920, during the Polish-Soviet War, he volunteered for the 8th Field Artillery Regiment. In 1921, he started studies at Warsaw University of Technology (Warsaw Tech), where he met Stanislaw Rogalski and Jerzy Drzewiecki. He was one of founders of the Aviation Section of Students' Mechanical Club. In December 1925, students of the Section founded their own workshop, where they built aircraft. In 1926, Wigura and Rogalski designed their first light aircraft WR-1, built in 1927. In 1927, three designers: Rogalski, Wigura, and Drzewiecki started working together, creating the RWD team (it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for n ...

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

RWD-17
The RWD 17 was a Polish aerobatics-trainer aircraft of 1937, parasol wing monoplane, constructed by the RWD team. Development The aircraft was designed for an order of the LOPP paramilitary organization, as an interim trainer aircraft between primary trainer RWD 8 and single-seater aircraft, demanding higher skills, like the RWD 10. It was also fitted to aerobatics. The construction of the new aircraft was very similar to the RWD 8, but almost all parts were newly designed. Main visual difference were twin struts supporting wings, instead of V-struts, and two-part wing instead of three-part, without central section. The works started in 1936, and the main designer was Bronisław Żurakowski of the RWD bureau. The first prototype (registration SP-BMX) was flown in August 1937 in Warsaw. After state trials in 1937, it was accepted for production, and in 1938 a short series of RWD 17 was produced (23 serial RWD 17 were in the Polish registry). In early 1938, a floatplane variant R ...
