Polikarpov PM-1
The Polikarpov PM-1 was a passenger aircraft created by Polikarpov in the 1920s. Design and development The PM-1 (PM - ''Passazhirskii Maybach'' – passenger transport Maybach engine) was a wooden biplane with a monocoque fuselage built up from glued ply veneer sheets (known as ''Sphon''), including the integral tail-fin. The two-spar wings were skinned in plywood forward of the main spars and covered in fabric aft of the main-spars. All control surfaces were built in a similar fashion with ply-skinned structural members and built-up wooden structure covered in fabric. Large I-type inter-plane struts, canted at about 30°, and steel cables braced the wings, which were attached to the fuselage at the top and bottom of the main fuselage frames. The undercarriage consisted of 2 main-wheels on a live axle supported by V-stuts with bungee springing. The Maybach Mb.IVa engine was mounted conventionally in the nose and had a retractable radiator forward of the undercarriage. Operatio ...

Polikarpov
Polikarpov Design Bureau was a Soviet OKB (design bureau) for aircraft, led by Nikolai Nikolaevich Polikarpov. Dux Factory was acquired by the USSR and became part of Polikarpov. After the death of Polikarpov on 30 July 1944 at the age of 52, his OKB was absorbed into Lavochkin, but with some of its engineers going to Mikoyan-Gurevich and its production facilities going to Sukhoi. For a long time the Polikarpov OKB headquarters were located at Aircraft plant #1 (formerly Dux Factory) in Moscow, where its purpose-built building still stands. Designs Polikarpov designs: Bombers * TB-2 twin-engined biplane bomber prototype, 1930 * SPB (D) twin-engined dive bomber developed from the VIT-2, 1940 * NB (T) medium bomber prototype, 1944 Fighters * I-1 (IL-400) monoplane fighter prototype, 1923 * DI-1 (2I-N1) twin-seat biplane fighter prototype, 1926 * I-3 biplane fighter, 1928 * DI-2 two-seat biplane fighter developed from the I-3, 1929 * I-6 biplane fighter prototype, ...

Maybach Mb
Maybach (, ) is a German luxury car brand that exists today as a part of Mercedes-Benz. The original company was founded in 1909 by Wilhelm Maybach and his son Karl Maybach, originally as a subsidiary of ''Luftschiffbau Zeppelin GmbH'', and it was known as ''Luftfahrzeug-Motorenbau GmbH'' until 1999. In 1960, Maybach was acquired by Daimler-Benz. The name returned as a standalone ultra-luxury car brand in 2002, sharing significant components with Mercedes-Benz cars. After slow sales, Maybach ceased to be a standalone brand by 2013, and it became (in 2015) a sub-brand of Mercedes-Benz, which is owned by the Mercedes-Benz Group. , Daimler produces an ultra-luxury edition of the Mercedes-Benz S-Class and Mercedes-Benz GLS-Class under the Mercedes-Maybach name. 1909–1940: Early history Wilhelm Maybach was technical director of the ''Daimler-Motoren-Gesellschaft'' (DMG) until he left in 1907. On 23 March 1909, he founded the new company, ''Luftfahrzeug-Motorenbau GmbH'' (lite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...
