RWD 22
RWD 22 was a Polish twin-engine torpedo bomber and naval reconnaissance floatplane design. Developed by Leszek Dulęba and Andrzej Anczutin of Doświadczalne Warsztaty Lotnicze (''Experimental Aeronautical Workshops'', DWL) in 1939, the project was to be developed under the brand of the RWD design bureau. The outbreak of World War II interrupted the design and it never left the planning stage. Design and development In late 1930s the Polish Navy sought a replacement for the ageing R-XIIIter and Lublin R-VIII. The new design was to replace those aircraft in both the torpedo bomber and close-range reconnaissance roles. Design of the RWD 22 started in October 1938 and by January 1939 the basic three projects were ready, each with different engine and armament configuration, but with a similar silhouette. The first version was to be equipped with a German-built Argus As-10c with of power and would carry up to of bombs. The second variant was equipped with second generation W ...

Floatplane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

Polish Złoty
The złoty (; abbreviation: zł; code: PLN) is the official currency and legal tender of Poland. It is subdivided into 100 grosz (''gr'').Singular: ''grosz'', alternative plural forms: ''groszy'', ''grosze''. The widely recognised English form of the currency name is the Polish zloty. It is the most traded currency in Central and Eastern Europe and ranks 22nd most-traded in the foreign exchange market. The word złoty is a masculine form of the Polish adjective 'golden', which closely relates with its name to the guilder whereas the grosz subunit was based on the groschen, cognate to the English word groat. It was officially introduced to replace its predecessor, the Polish mark, on 28 February 1919 and began circulation in 1924. The only body permitted to manufacture or mint złoty coins is Mennica Polska, founded in Warsaw on 10 February 1766. As a result of inflation in the early 1990s, the currency underwent redenomination. Thus, on 1 January 1995, 10,000 old złoty (PLZ) ...

RWD-14 Czapla
The RWD-14 Czapla (LWS Czapla) was a Polish army cooperation aircraft (observation, close reconnaissance and liaison aircraft), designed in the mid-1930s by the RWD team, and produced in the LWS factory from 1938. A series of 65 aircraft were built and most were used by the Polish Air Force observation squadrons during World War II in 1939. Design and development The aircraft was designed in response to a Polish Air Force requirement of 1933 for a new army cooperation plane, a successor of the Lublin R-XIII. The RWD team of the DWL workshops (''Doświadczalne Warsztaty Lotnicze'') initially proposed the RWD-12 project, based on the RWD-8 trainer. It was however considered as not as good as the R-XIII, and was not built. Another aircraft, the RWD-14 was designed by Stanislaw Rogalski and Jerzy Drzewiecki instead.Glass A. (1977), pp. 318–320 Designer Tadeusz Chyliński prepared its technical documentation. The first prototype was flown in early 1936 (according to newest rese ...

PZL G-1620B Mors II
PZL (''Państwowe Zakłady Lotnicze'' - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, and a brand of their aircraft. Based in Warsaw between 1928 and 1939, PZL introduced a variety of well-regarded aircraft, most notably the PZL P.11 fighter, the PZL.23 Karaś light bomber, and the PZL.37 Łoś medium bomber. In the post-war era, aerospace factories in Poland were initially run under the name WSK (Transport Equipment Manufacturing Plant), but returned to adopt PZL acronym in late 1950s. This was used as a common aircraft brand and later as a part of names of several Polish state-owned aerospace manufacturers referring to PZL traditions, and belonging to the ''Zjednoczenie Przemysłu Lotniczego i Silnikowego PZL'' - PZL Aircraft and Engine Industry Union. Among the better-known products during this period is the PZL TS-11 Iskra jet trainer and PZL-104 Wilga STOL utility aircraft. After the fall of communism in Poland in 1989, th ...
