PWS-12
The PWS-12 was a biplane trainer designed and developed by Podlaska Wytwórnia Samolotów (PWS). It entered production as the PWS-14. Development The PWS-12 was a single-engined two-seat training biplane, fit also for aerobatics, designed in 1928 by A. Grzędzielewski and August Bobek-Zdaniewski at the PWS factory. The design shared similar parts, including fuselage and engine, as a high-wing trainer fighter plane PWS-11, developed at the same time.Glass, A. (1977) The main difference was the addition of a lower wing. It was powered by a nose-mounted Skoda-built version of the Wright J-5 Whirlwind radial engine. Two prototypes and an airframe for static tests were ordered by the Aviation Department of the War Ministry in February 1928 (along with the PWS-11 prototypes). The first prototype was flown by Franciszek Rutkowski in November 1929. It was later improved - among others, a Townend ring replaced NACA cowling, and it was fitted with N-shaped struts between wings instead of p ...

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-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 ...

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 ...

PWS-11
The PWS-11 was a Polish aerobatic and trainer aircraft, developed in 1928-1929 by PWS (''Podlaska Wytwórnia Samolotów'' - Podlasie Aircraft Factory), which remained a prototype. Design and development In parallel with development of a fighter aircraft, the PWS-10, the design team of Aleksander Grzędzielewski and Augustyn Bobek-Zdaniewski from the PWS factory, started work on an intermediate aircraft for training fighter pilots. Like the PWS-10, the new plane was of a parasol wing configuration, but the shape of the fuselage, wings and empennage were similar to a liaison aircraft, the PWS-5 of the same designers and powered by the same engine. In 1929, the Aviation Department of the Polish War Ministry ordered the prototypes and an airframe for static tests. The plane was initially known as PWS-11SM, for ''szkolno-myśliwski'' (fighter/trainer). The first prototype of the PWS-11 was flown in November 1929 at Biała Podlaska by Franciszek Rutkowski.

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".

Grudziądz ( la, Graudentum, Graudentium, german: Graudenz) is a city in northern Poland, with 92,552 inhabitants (2021). Located on the Vistula River, it lies within the Kuyavian-Pomeranian Voivodeship and is the fourth-largest city in its province. The Old Town of Grudziądz and 14th-century granaries were declared National Historic Monuments of Poland.

Dęblin
Dęblin is a town at the confluence of Vistula and Wieprz rivers, in Lublin Voivodeship, Poland. Dęblin is the part of the agglomeration with adjacent towns of Ryki and Puławy, which altogether has over 100 000 inhabitants. The population of the town itself is 15,505 (December 2021). Dęblin is part of the historic region of Lesser Poland. Since 1927 it has been the home of the chief Polish Air Force Academy ( pl, Lotnicza Akademia Wojskowa), and as such Dęblin is one of the most important places associated with aviation in Poland. The town is also a key railroad junction, located along the major Berlin – Warsaw line, with two additional connections stemming from Dęblin – one westwards to Radom, and another one northeast to Łuków. History Dęblin was first mentioned as a village in historical documents dating from 1397. At that time, it was ruled by Castellans from Sieciechów. It was a private village of Polish nobility, including the Mniszech family, administrati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NACA Cowling
The NACA cowling is a type of aerodynamic fairing used to streamline radial engines installed on airplanes. It was developed by Fred Weick of the National Advisory Committee for Aeronautics (NACA) in 1927. It was a major advance in aerodynamic drag reduction, and paid for its development and installation costs many times over due to the gains in fuel efficiency that it enabled. History and design The NACA cowling enhanced speed through drag reduction while delivering improved engine cooling. The cowling consists of a symmetric, circular airfoil that is wrapped around the engine. In a normal planar airfoil, like a wing, it is the difference in airspeed, and their associated changes in pressure, on the top and bottom of the surface that produces lift. In the case of the NACA cowl, the ring-shaped airfoil is positioned so this lift effect is forward, producing thrust. This thrust does not counteract the total drag of the cowl, but greatly reduces its overall value. The differenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
