Podlaska Wytwórnia Samolotów
Podlaska Wytwórnia Samolotów (PWS) - ''Podlasie Aircraft Factory'' - was a Polish aerospace manufacturer between 1923 and 1939, located in BiaÅ‚a 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 CywiÅ„ski, ZbysÅ‚aw CioÅ‚kosz, 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation 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 Agency in Canada, Indian Space Re ...

PWS-10
The PWS-10 was a Polish fighter aircraft, constructed in the PWS (''Podlaska Wytwórnia Samolotów'' - Podlasie Aircraft Factory). It was the first Polish-designed fighter to enter serial production. Design and development First work on a domestic fighter to replace ill-fated French SPAD 61s in the Polish Air Force was initiated by PWS in 1927. The main designers were Aleksander GrzÄ™dzielski and Augustyn Zdaniewski. In 1929 the prototype was built and it first flew in March 1930. At the same time, the more modern fighter PZL P.1 was developed by the PZL. Despite the P.1 being a more capable fighter, the War Ministry decided that it needed further work, and a series of 80 PWS-10 was ordered as a temporary measure. In comparison with the advanced P.1, the PWS-10 was a more classic design, a high-wing parasol monoplane of mixed construction. The series was built from 1931 to 1932, numbered from 5-1 to 5-80. A variant of PWS-10 was a biplane PWS-15, being PWS-10 with another pai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lviv
Lviv ( uk, Львів) is the largest city in western Ukraine, and the seventh-largest in Ukraine, with a population of . It serves as the administrative centre of Lviv Oblast and Lviv Raion, and is one of the main cultural centres of Ukraine. It was named in honour of Leo, the eldest son of Daniel, King of Ruthenia. Lviv emerged as the centre of the historical regions of Red Ruthenia and Galicia in the 14th century, superseding Halych, CheÅ‚m, Belz and PrzemyÅ›l. It was the capital of the Kingdom of Galicia–Volhynia from 1272 to 1349, when it was conquered by King Casimir III the Great of Poland. From 1434, it was the regional capital of the Ruthenian Voivodeship in the Kingdom of Poland. In 1772, after the First Partition of Poland, the city became the capital of the Habsburg Kingdom of Galicia and Lodomeria. In 1918, for a short time, it was the capital of the West Ukrainian People's Republic. Between the wars, the city was the centre of the Lwów Voivodeship in th ...

PWS-35
The PWS-35 ''Ogar'' ( en, Polish Hound) was a two-seat, aerobatic training biplane that was designed by Kazimierz Nowicki, Marian PiÄ…tka and MichaÅ‚ Rosnowski at the Lviv Polytechnic in 1935/1936. Design and development The aircraft was designed by three young scientists at the Lvov University of Technology ("Polytechnic") as their thesis. The designers initially planned to build a single aircraft (designated as the NPR-1, after the initials of the design team's members), but in 1937 the Podlaska Wytwórnia Samolotów became interested in their design and hired professional designers to modify it to fit the needs of the Polish Air Force. At the time the PAF was looking for an advanced trainer and it was decided that Ogar would be perfect for that role. The prototype was completed in 1937 and in early 1938 underwent static tests. In the summer of 1938 it was successfully test-flown by S. Szubka. The first prototype, equipped with a de Havilland Gipsy Major engine, was heavier th ...

PWS-33 Wyżeł
The PWS-33 WyżeÅ‚ was a Polish twin-engined military trainer aircraft from a period before World War II constructed by ''Podlaska Wytwórnia Samolotów'' or PWS (" Podlasie Aircraft Factory"). Although destined for production it got no further than the prototypes before Poland was invaded. Design and development With an expected advent of a twin-engine heavy fighter, the PZL.38 Wilk, which was supposed to be a basic fighter and bomber aircraft in the Polish Air Force, there appeared the need for a twin-engine trainer aircraft for pilots. In 1936, the PWS works were ordered to build a trainer of cheap wooden construction, similar in layout to the PZL.38. The main designer was WacÅ‚aw CzerwiÅ„ski, known for designing several successful sailplanes. The prototype of the PWS-33 first flew in August–September 1938. The aircraft appeared successful with good flight characteristics and the maximum speed turned out to be even higher than had been estimated. It was given a name ''WyÅ ...

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]   |

PWS-26
The PWS-26 was a Polish advanced training aircraft, used from 1937 to 1939 by the Polish Air Force, constructed in the PWS (''Podlaska Wytwórnia Samolotów'' - Podlasie Aircraft Factory). It was the second most numerous Polish pre-war aircraft, after the RWD-8. Design and development The aircraft was a final development of a series: PWS-12, PWS-14 and PWS-16, designed in response to a Polish Air Force requirement for an advanced trainer. The chief designer was Augustyn Zdaniewski. The PWS-26 was a direct development of the PWS-16bis, sharing the same silhouette, being a more militarized variant - with strengthened construction, which allowed dive-bomber training. Contrary to its predecessors, the PWS-26 could be armed with a forward-shooting machine gun and practice bombs. It also had other improvements and was capable of aerobatics. A visual difference from the PWS-16bis were the canvas-covered struts of the landing gear. The prototype was flown in 1935. After trials, its pr ...

PWS-16
The PWS-16 was a biplane trainer designed and developed by Podlaska Wytwórnia Samolotów (PWS). An armed variant also entered production as the PWS-26. Development Developed from the PWS-12 and PWS-14 trainers, the PWS-16 two-seat biplane design introduced a number of improvements particularly improved ailerons. A variant designated PWS-16bis had a revised fuel system to allow inverted flight. It had also improved aerodynamics and its silhouette changed. The aircraft entered service with the Polish Air Force training units between 1933 and 1934. An improved armed version was developed as the PWS-26 and when the PWS-26 entered service in 1937, the PWS-16 was relegated to secondary duties.

PWS-18
The PWS-18 was a Polish trainer aircraft, used from 1937 to 1939 by the Polish Air Force, a modified licence variant of the British Avro Tutor. Development In 1934, the Polish government, looking for an intermediate military trainer, bought two Avro Tutor trainer aircraft together with a licence to produce the aircraft. Production was ordered in the PWS (''Podlaska Wytwórnia Samolotów'' - Podlasie Aircraft Factory). In 1935, Antoni Uszacki of the PWS modified the design, fitting it with a Wright Whirlwind engine, produced under licence in Poland. The new engine cowling was much longer than the previous Townend ring type, with a carburetor air intake below it. The wing construction was changed from metal to wooden, better fitted to PWS capabilities, and the rectangular wing tips were rounded. Also some other details were changed, such as a tailskid instead of a tailwheel. A series of 40 aircraft was built in 1935-1936 (1936-1937 according to some references). They were assigne ...

Avro Tutor
The Avro Type 621 Tutor is a two-seat British radial-engined biplane from the interwar period. It was a simple but rugged basic trainer (aircraft), trainer that was used by the Royal Air Force as well as many other air arms worldwide. Design and development The Avro Model 621 was designed by Roy Chadwick as an Avro private venture metal replacement for the Avro 504. Conceived as a light initial pilot trainer, the biplane design featured heavily staggered equal-span, single-bay wings; the construction was based on steel tubing (with some wooden components in the wing ribs) with aircraft dope, doped linen covering. A conventional, fixed divided main undercarriage with tailskid was used in all but the latest aircraft, which had a tailwheel. The Model 621 was powered either by a 155 hp (116 kW) Armstrong Siddeley Mongoose or Armstrong Siddeley Lynx IV (180 hp/130 kW) or IVC (240 hp/179 kW) engine; later Lynx-powered models had the engine enclosed in a ...

RWD (aircraft Manufacturer)
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, StanisÅ‚aw Rogalski, StanisÅ‚aw 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 KoÅ‚a 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 OkÄ™cie district in Warsaw, near the OkÄ™cie aerodrome, today's Warsaw International Airport, founded by the LOPP paramilitary organization. ...

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 StanisÅ‚aw Rogalski, StanisÅ‚aw 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 (''DoÅ›wiadczalne 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 ...
