Tupolev Tu-70
The Tupolev Tu-70 (russian: Туполев Ту-70; NATO reporting name: Cart) was a Soviet passenger variant of the Tu-4 bomber (which was reverse-engineered from the American Boeing B-29 Superfortress) and designed immediately after the end of World War II. It used a number of components from Boeing B-29s that had made emergency landings in the Soviet Union after bombing Japan. It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946.Gordon, p. 105 The aircraft was successfully tested, recommended for serial production, but ultimately not produced because of more pressing military orders and because Aeroflot had no requirement for such an aircraft. A military cargo aircraft version was the Tupolev Tu-75. Design and development After basic design work was completed on the Tu-4 bomber, Tupolev decided to design a passenger variant with a pressurized fuselage, given the internal designation of Tu-70. It was intended to use as many Tu-4 component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airliner
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shvetsov ASh-73TK
The Shvetsov ASh-73 was an 18-cylinder, air-cooled, radial aircraft engine produced between 1947 and 1957 in the Soviet Union. It was primarily used as the powerplant for the Tupolev Tu-4 heavy bomber, a copy of the American Boeing B-29 Superfortress. Design and development The Shvetsov ASh-73 originated in 1938 from a specification for an 18-cylinder, twin-row, development of the Shvetsov M-25, a license-built 9-cylinder, air-cooled, radial Wright R-1820-F3 Cyclone engine. Development continued through a series of less than successful engines, before culminating in the ASh-73. Contrary to popular belief the ASh-73 wasn't a reverse engineered copy of the Wright R-3350 Duplex-Cyclone, itself starting its development in 1937: "There was no need to copy the Wright R-3350-23A; the engine that was put into production was the indigenous ASh-73TK - a further development of the M-71 and M-72, which differed in being fitted with twin TK-19 turbosuperchargers (TK = ''toorbokompressor'')."Go ...

Low-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 ...

Soviet Union–United States Relations
Soviet Union–United States relations were fully established in 1933 as the succeeding bilateral ties to those between the Russian Empire and the United States, which lasted from 1776 until 1917; they were also the predecessor to the current bilateral ties between the Russian Federation and the United States that began in 1992. The relationship between the Soviet Union and the United States was largely defined by mistrust and tense hostility. The invasion of the Soviet Union by Nazi Germany as well as the attack on the U.S. Pacific Fleet at Pearl Harbor by Imperial Japan marked the Soviet and American entries into World War II on the side of the Allies in June and December 1941, respectively. As the Soviet–American alliance against the Axis came to an end following the Allied victory in 1945, the first signs of post-war mistrust and hostility began to immediately appear between the two countries. These bilateral tensions escalated into the Cold War, a decades-long period of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ilyushin Il-18 (1947)
The Ilyushin Il-18 was a Soviet four-engined airliner designed and built by Ilyushin immediately after World War II. Although the aircraft itself was successful, its Shvetsov ASh-73TK engines were too unreliable for civilian use and were further needed to equip the Tupolev Tu-4 bomber, so it was cancelled in 1948. Development The Il-18 was developed to meet Aeroflot's need for a high-altitude, long-range aircraft to fly its long-haul national and international routes. It was conceived as a cantilever low-wing monoplane, powered by four Charomskii ACh-32 diesel engines, as initially used in the Ilyushin Il-12, with a tricycle landing gear. To improve the wing's lift-to-drag ratio and the aircraft's maximum speed, the wing was given a very high aspect ratio of 12. It was intended to operate from both paved and unpaved runways with a length of less than . Its main wheels were larger than normal to handle the rough surfaces. The pressurized fuselage was circular in cross-section, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 377 Stratocruiser
The Boeing 377 Stratocruiser was a large long-range airliner developed from the C-97 Stratofreighter military transport, itself a derivative of the B-29 Superfortress. The Stratocruiser's first flight was on July 8, 1947. Its design was advanced for its day; its innovative features included two passenger decks and a pressurized cabin. It could carry up to 100 passengers on the main deck plus 14 in the lower deck lounge; typical seating was for 63 or 84 passengers or 28 berthed and five seated passengers. The Stratocruiser was larger than the Douglas DC-6 and Lockheed Constellation and cost more to buy and operate. Its reliability was poor, chiefly due to problems with the four 28-cylinder Pratt & Whitney R-4360 Wasp Major radial engines and structural and control problems with their propellers. Only 55 Model 377s were built for airlines, along with the single prototype. The 377 was also converted into the Aero Spacelines Pregnant Guppy by John M. Conroy for NASA’s Gemini sp ...

Tupolev Tu-85
The Tupolev Tu-85 (russian: Туполев Ту-85; USAF/ DoD reporting name: "Type 31", NATO reporting name: Barge) was a Soviet prototype strategic bomber based on the Tu-4, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. It was the ultimate development of the B-29 family, being over 50% heavier than its progenitor and had nearly double the range. Only two prototypes were built before the program was cancelled in favor of the turboprop powered Tupolev Tu-95 bomber which could cover the same range at a far higher speed. Development Neither the Tu-4 nor the Tupolev Tu-80 were true intercontinental strategic bombers as they both lacked the range to attack the United States from bases in the Soviet Union and return. The Tu-85 was designed to achieve the necessary range by use of more powerful and fuel-efficient engines, a redesigned wing to increase the lift/drag ratio and the addition of more fuel. A large number of engines were considered before settling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
