LWS-7 Mewa II
The LWS-7 Mewa II ("Seagull") was a Polish observation and close reconnaissance aircraft, designed in the 1939 by the LWS factory as a development of the earlier LWS-3 Mewa. Aircraft development was ordered by the Polish Air Force, but no prototypes were built. Design and development In 1939, the LWS-7 Mewa II was being developed at the LWS as the development of the LWS-3 Mewa. New wings and a semi-monocoque fuselage with less drag were introduced. It was to be fitted with a more powerful 916 hp (683 kW) PZL Pegaz XX engine (Bristol Pegasus XX) or a planned 1000 hp (750 kW) PZL Waran. A maximum speed of 400–420 km/h was estimated. Before the war, only a wooden model for aerodynamics tests was made. Tests performed by Aerodynamic Institute of Warsaw University of Technology showed that the maximum speed of the LWS-7 could be estimated at 420–425 km/h - about 60 km/h more than the LWS-3 Mewa. Complete technical drawings were prepared in Su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Wikimedia project, 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 Magazine, 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".

LWS-6 Żubr
The LWS-6 Żubr (PZL.30, ''wisent'') was a twin-engined medium bomber designed and produced by the Polish aircraft manufacturer LWS. It was only produced in limited numbers and was used for training purposes as it proved to be inferior to the contemporary PZL.37 ''Łoś'' medium bomber. The LWS-6 was originally designed as a 12-passenger airliner during the early 1930s, but was reconfigured to produce bomber instead. During March 1936, the first prototype, designated ''PZL.30'' (or ''PZL.30BI''), performed its maiden flight. The aircraft was accepted for a limited production run by the LWS state factory in Lublin for the Polish Air Force. During 1937, work commenced on a floatplane torpedo bomber variant, designated the ''LWS-5'', for the Polish Navy, but work on the prototype was abandoned following setbacks. Export sales were also sought, the Romanian Air Force were reportedly considering buying up to 24 aircraft, however, following the loss of one of the prototypes on 7 Nov ...

KB-11 Fazan
The Kaproni Bulgarski KB-11 Fazan ( en, Pheasant) was a 1940s Bulgarian army liaison and utility monoplane built by Kaproni Bulgarski, a subsidiary of the Italian aviation conglomerate Società Italiana Caproni. Development and design The prototype Fazan flew in 1941 as a shoulder-wing monoplane powered by a Alfa Romeo 126 R.C.34 radial engine. It had a fixed conventional landing gear with a tailwheel. Flight testing of the prototype showed that the aircraft was unstable and was nose-heavy in level flight, and was considered unsafe during forced-landings. By analogy with the Hunchback of Notre-Dame, the prototype gaining the unflattering nickname "Quasimodo".Bernád 2001, p. 16. The second prototype was redesigned with a high-wing, a revised undercarriage and new cockpit glazing, while retaining the engine and three-bladed fixed-pitch propeller of the first prototype. The revised aircraft successfully passed its flight trials, and a small batch of six similar aircraft, design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westland Lysander
The Westland Lysander is a British army co-operation and liaison aircraft produced by Westland Aircraft that was used immediately before and during the Second World War. After becoming obsolete in the army co-operation role, the aircraft's short-field performance enabled clandestine missions using small, improvised airstrips behind enemy lines to place or recover agents, particularly in occupied France with the help of the French Resistance. Royal Air Force army co-operation aircraft were named after mythical or historical military leaders; in this case the Spartan admiral Lysander was chosen. Design and development In 1934 the Air Ministry issued Specification A.39/34 for an army co-operation aircraft to replace the Hawker Hector. Initially Hawker Aircraft, Avro and Bristol were invited to submit designs, but after some debate within the Ministry, a submission from Westland was invited as well. The Westland design, internally designated P. 8, was the work of Arthur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel Hs 126
The Henschel Hs 126 was a German two-seat reconnaissance and observation aircraft of World War II that was derived from the Henschel Hs 122. The pilot was seated in a protected cockpit under the parasol wing and the gunner in an open rear cockpit. The prototype aircraft frame was that of a Hs 122A fitted with a Junkers engine. The Hs 126 was well received for its good short takeoff and low-speed characteristics which were needed at the time. It was put into service for a few years, but was soon superseded by the general-purpose, STOL Fieseler Fi 156 ''Storch'' and the medium-range Focke-Wulf Fw 189 "flying eye". Development The first prototype was not entirely up to ''Luftwaffe'' standards; it was followed by two more development planes equipped with different engines. Following the third prototype, ten pre-production planes were built in 1937. The Hs 126 entered service in 1938 after operational evaluation with the ''Legion Condor'' contingent to the Spanish Civil War. Operati ...

PZL-Bristol Pegasus XIX
The Bristol Pegasus is a British nine-cylinder, single-row, air-cooled radial aero engine. Designed by Roy Fedden of the Bristol Aeroplane Company, it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Mercury and Jupiter engines, later variants could produce 1,000 horsepower (750 kW) from its capacity of 1,750 cubic inches (28 L) by use of a geared supercharger. Further developments of the Pegasus created the fuel-injected Bristol Draco and the diesel cycle Bristol Phoenix, both types being produced in limited numbers. In contrast, by the end of production over 30,000 Pegasus engines had been built. Aircraft applications ranged from single-engine biplanes to the four-engined Short Sandringham and Sunderland flying boats. Several altitude and distance records were set by aircraft using the Pegasus. The Bristol Siddeley company reused the name many years later for the turbofan engine used in the Hawker Siddeley Har ...
