PWS-19
The PWS-19 was a Polish reconnaissance and bomber plane prototype of the 1930s, constructed in the PWS (''Podlaska Wytwórnia Samolotów'' - Podlasie Aircraft Factory). Development The PWS-19 was constructed in 1930 in order to replace the French-designed bombers Potez 25 and Breguet 19 in the Polish Air Force. It was a development of the PWS-17, which remained unbuilt. Main designers were Zbysław Ciołkosz and Antoni Uszacki. It was planned to be produced in two variants: reconnaissance PWS-19A2 and bomber PWS-19B2. It was a conventional design, a strutted high-wing monoplane with quite elegant silhouette, open cockpits and fixed landing gear. It was fitted with double tailfins to obtain a good field of defense fire. In 1934 Antoni Uszacki designed a smaller plane basing on the PWS-19, designated PWS U-6, with G-1620 Mors 400 hp engine. It participated in a contest for an army cooperation plane, but lost against RWD-14 Czapla and was not built. Operational histor ...

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 ...

Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin.

Etymology The word cockpit seems to have been cockpit (sailing), used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore.

PWS-24
The PWS-24 was a Polish single-engine passenger aircraft for 4 passengers, built in PWS factory, used from 1933 to 1936 by LOT Polish Airlines. In spite of its limited capacity, it was the only series-built airliner of domestic design ever used by the LOT.PZL.4, PZL.27, PZL.44 Wicher and PZL MD-12 were evaluated by LOT, being prototypes. Development The aircraft was a development of an unsuccessful PWS-21, utilizing its lightweight construction wing (weight 300 kg). A fuselage and stabilizers were new. The main designer was Stanisław Cywiński. The prototype (markings SP-AGR) first flew in August 1931 in Biała Podlaska. After trials and some modifications, it won a Ministry of Communication's contest for a successor of Junkers F-13 in LOT airlines, against Lublin R-XVI. In June 1932 it took the first place in a passenger aircraft race at the international air meeting in Warsaw. Polish Ministry of Communication ordered a series of 5 aircraft for LOT airlines, built in 1933 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PWS-21
The PWS-21 was a Polish passenger aircraft for 4 passengers, built in PWS factory in 1930, that remained a prototype. Development The aircraft was developed for a contest for a successor of Junkers F-13 in LOT Polish Airlines. The first design of 1929, named PWS-21, developed by Stanisław Cywiński and Jarosław Naleszkiewicz, was a braced high-wing plane, but it was not realized because LOT demanded bigger passenger cab. The next design, named PWS-21bis, was a cantilever high-wing plane, similar to Fokker F.VIIa/1m design. The only prototype (markings SP-AEC) first flew in the spring, probably April 1930 in Biała Podlaska. Its counterpart was Lublin R-XI. The plane appeared not successful. It was too heavy, what resulted in poor speed, ceiling and range, and long take off. In 1931 it was evaluated in LOT airlines, but after a test flight it was returned to the factory. However, at that time there was its development, PWS-24 built, sharing the same lightweight wing, which was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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-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 Grzędzielski 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] |

Vickers Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allies of World War I, Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every Britis ...
