PWS-20
The PWS-20 was a Polish single-engine high-wing 8 passenger airliner, built in the PWS factory and when it made its first flight in 1929 it became the first Polish-designed transport aircraft to fly. Development The aircraft was developed by Zbysław Ciołkosz in response to a request announced by the Polish Ministry of Communication in 1927 for an airliner to be used by LOT Polish Airlines, and was competing against a sizable number of other designs from other Polish designers, including the Stemal VII, 4 unbuilt proposals from PZL, the Lublin R-IX, and the Medwecki M.N.2. Of the designs submitted, the PWS-20 was selected as being the best design. A prototype was built and first flew on 12 March 1929 from Biała Podlaska. After brief flight testing it was bought by the Ministry of Communication for evaluation as the PWS-20T, with the T signifying transport. In 1930, following testing by LOT, the aircraft was modified with a wider undercarriage, improved windscreen, engine coo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1930s Polish Airliners
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.

Stinson Detroiter
The Stinson Detroiter was a six-seat cabin airliner for passengers or freight designed and built by the Stinson Aircraft Syndicate, later the ''Stinson Aircraft Corporation''. Two distinct designs used the Detroiter name, a biplane and a monoplane. Development The first design from the Detroit-based Stinson Aircraft Syndicate was the Stinson SB-1 Detroiter, a four-seat cabin biplane with novel features such as cabin heating, individual wheel brakes and electric starter for the nose-mounted 220 hp (164 kW) Wright J-5 Whirlwind engine. It made its first flight on Jan 25th, 1926. The Harley Davidson brakes were demonstrated on a snowy maiden flight requiring wheel chains to be added to prevent skidding. This aircraft was soon developed into the six-seat Stinson SM-1D Detroiter, a braced high-wing monoplane version which ultimately made quite a number of significant long-range flights. The aircraft was soon a success and it enabled Stinson to get $150,000 in public capital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messerschmitt M 18
The Bayerische Flugzeugwerke M 18 (BFW M 18), (later known as Messerschmitt M 18) was an airliner, produced in Germany in the late 1920s. Design and development Designed at the request of Theodor Croneiss to supply his new airline venture which was to become '' Nordbayerische Verkehrsflug'' (NOBA), it was a conventional high-wing cantilever monoplane with fixed tailskid undercarriage. The prototype was built of wood, although production examples would have a metal structure. The design was praised in its day for the cleanness of its aerodynamics, lightness of construction, and economy of operation Operational history The first M 18 to enter service with NOBA was provided by Messerschmitt in exchange for a 49% share of the new company, and on 26 July it began commercial flights. NOBA's early successes enabled the company to place orders for additional examples of an improved model, the M 18b. It would eventually purchase twelve of these, but manufacturing them would exceed the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latécoère 28
The Latécoère 28 was a successful French long-haul mail plane and passenger airliner of the 1930s. It was the main-stay of Air France's predecessor, Aéropostale (aviation), Aéropostale in its efforts to establish intercontinental air mail services and support French colonialism and French cultural influence between the wars. Its pilots included famous poets and French men of letters such as Antoine de Saint Exupéry and Jean Mermoz as well as the usual veterans from World War I. Design and development The Latécoère 28 was a development of the Latécoère 26. It was braced high-wing single-engined monoplane initially powered by a Renault 12Jbr engine. The Latécoère 28 had a fixed tailwheel undercarriage and enclosed cockpit for two crew. The cabin was fitted for eight-passengers with access to a washroom. A total of about fifty planes of several versions were built between 1927 and 1932. The seaplane version, the Latécoère 28-3, was the first to make a postal delivery ...

Focke-Wulf A 17 Möwe
The Focke-Wulf A 17 ''Möwe'' (German: "Gull") was an airliner built in Germany in the late 1920s. It was a conventional high-wing cantilever monoplane with fixed tailwheel undercarriage. The aircraft provided fully enclosed seating for up to eight passengers and had a separate, fully enclosed flight deck for the two pilots. Most examples flew with Deutsche Luft Hansa, serving until around 1936. In the early 1930s, two A 17s were used for testing the Junkers Jumo 5 diesel engine. In 1929, an example was built with a BMW VI engine and fitted out for aerial photography and survey work and designated A 21. The cabin was equipped with a darkroom. Later the same year, the BMW engine was used on a further five airliners for Luft Hansa, these being designated A 29. Variants * A 17 - Eight-passenger airliner powered by Gnome et Rhône 9Aa Jupiter. One prototype and 11 production aircraft. ** A 17a - Conversion of A 17 with geared Siemens Jupiter VI engine. ** A 17b - Conversion with ...

Farman F
Farman Aviation Works (french: Avions Farman) was a French aircraft company founded and run by the brothers Richard, Henri, and Maurice Farman. They designed and constructed aircraft and engines from 1908 until 1936; during the French nationalization and rationalization of its aeronautical industry, Farman's assets were assigned to the ''Société Nationale de Constructions Aéronautiques du Centre'' (SNCAC). In 1941 the Farman brothers reestablished the firm as the "''Société Anonyme des Usines Farman''" (SAUF), but only three years later it was absorbed by Sud-Ouest. Maurice's son, Marcel Farman, reestablished the SAUF in 1952, but his effort proved unsuccessful and the firm was dissolved in 1956. The Farman brothers designed and built more than 200 types of aircraft between 1908 and 1941. They also built cars until 1931 and boats until 1930. Background In 1907, Henri Farman bought his first aircraft from Gabriel Voisin and soon began to improve the design of the air ...

Fairchild 100 Pilgrim
The Fairchild 100 Pilgrim is an American single-engined high-wing monoplane transport, and was one of a series of single-engine utility transports built by Fairchild Aircraft. Design and development The 100 was similar in design to the Fairchild C-8 and was an enlarged version of it. The first flight of the aircraft (NC754Y) was October 22, 1930. Although only one aircraft was completed, a modified version also known as the Pilgrim 100-A was in production for American Airways, the first operator of the type in 1931. After a total of 16 aircraft, an additional batch of ten aircraft with a larger fin were manufactured by the restructured American Aircraft & Engine Corporation that emerged in 1931 from the Fairchild Aircraft Co. The continuing series was built under the designations, Pilgrim 100-B and American/Fairchild Y1C-24. The first six in the new series went to American Airways. The parent company later reinstated the Fairchild name. Operational history The sturdy Fairchild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duralumin
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium alloys. The term is a combination of '' Dürener'' and ''aluminium''. Its use as a trade name is obsolete. Today the term mainly refers to aluminium–copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 and 2024 alloys used in airframe fabrication. History Duralumin was developed by the German metallurgist Alfred Wilm at Dürener Metallwerke AG. In 1903, Wilm discovered that after quenching, an aluminium alloy containing 4% copper would harden when left at room temperature for several days. Further improvements led to the introduction of duralumin in 1909. The name is mainly used in pop-science to describe all Al-Cu alloys system, or '2000' series, as designated through the international alloy designation system originally created in 1970 by the Aluminum A ...
