Igor Sikorski
Igor Ivanovich Sikorsky, (25 May 1889 – 26 October 1972) was a Russian-American aviation pioneer in both helicopters and fixed-wing aircraft. His first success came with the Sikorsky S-2, the second aircraft of his design and construction. His fifth airplane, the S-5, won him national recognition and F.A.I. pilot's license number 64. His S-6-A received the highest award at the 1912 Moscow Aviation Exhibition, and in the fall of that year the aircraft won first prize for its young designer, builder and pilot in the military competition at Saint Petersburg. In 1913, the Sikorsky-designed ''Russky Vityaz'' (S-21) became the first successful four-engine aircraft to take flight. He also designed and built the ''Ilya Muromets'' (S-22 – S-27) family of four-engine aircraft, an airliner which he redesigned to be the world's first four-engine bomber when World War I broke out. After immigrating to the United States in 1919 because of the Russian Revolution, Sikorsky fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sikorsky S-5
The Sikorsky S-5 was an early Russian single seat biplane design by Igor Sikorsky, completed in late April 1911. Design and development The S-5 was powered by a Argus water-cooled engine turning a propeller Sikorsky designed and built himself. The fabric covering the wooden wings was tightened with pure alcohol and glue mixed with boiling water. The fuselage structure was left exposed. Instead of separate levers to control the elevator and ailerons as in his previous aircraft, Sikorsky designed a single control lever with a wheel allowing control of pitch and roll. This "control column" included a button switch to momentarily deactivate the ignition thereby controlling engine power. The rudder controls were reversed, because it better suited Sikorsky's tactility of the machine. Operational history The S-5 was tested in a series of 20 to 30-second straight-line flights, over a period of three weeks, before the designer was able to make what he called his first real flight ...

Russian Empire
The Russian Empire was an empire that spanned most of northern Eurasia from its establishment in November 1721 until the proclamation of the Russian Republic in September 1917. At its height in the late 19th century, it covered about , roughly one-sixth of the world's landmass, making it the list of largest empires, third-largest empire in history, behind only the British Empire, British and Mongol Empire, Mongol empires. It also Russian colonization of North America, colonized Alaska between 1799 and 1867. The empire's 1897 census, the only one it conducted, found a population of 125.6 million with considerable ethnic, linguistic, religious, and socioeconomic diversity. From the 10th to 17th centuries, the Russians had been ruled by a noble class known as the boyars, above whom was the tsar, an absolute monarch. The groundwork of the Russian Empire was laid by Ivan III (), who greatly expanded his domain, established a centralized Russian national state, and secured inde ...

Vought-Sikorsky VS-300
The Vought-Sikorsky VS-300 (or S-46) is an American single-engine helicopter designed by Igor Sikorsky. It had a single three-blade rotor originally powered by a 75 horsepower (56 kW) engine. The first "free" flight of the VS-300 was on 13 May 1940.Munson 1968, p. 111. The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. With floats attached, it became the first practical amphibious helicopter. Design and development Igor Sikorsky's quest for a practical helicopter began in 1938, when as the Engineering Manager of the Vought-Sikorsky Division of United Aircraft Corporation, he was able to convince the directors of United Aircraft that his years of study and research into rotary-wing flight problems would lead to a breakthrough. His first experimental machine, the VS-300, was test flown by Sikorsky on 14 September 1939, tether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-42
The Sikorsky S-42 was a commercial flying boat designed and built by Sikorsky Aircraft to meet requirements for a long-range flying boat laid out by Pan American World Airways (Pan Am) in 1931. The innovative design included wing flaps, variable-pitch propellers, and a tail-carrying full-length hull. The prototype first flew on 29 March 1934, and, in the period of development and test flying that followed, quickly established ten world records for payload-to-height. The "Flying Clipper" and the "Pan Am Clipper" were other names for the S-42. Design and development During the inaugural flight of Sikorsky's previous flying boat, the Sikorsky S-40, S-40, on November 19, 1931, the pilot and Pan American World Airways, Pan American Airways consultant, Charles Lindbergh, who considered the S-40 a monstrosity, engaged designer Igor Sikorsky in a conversation about what he thought the next airplane should look like.Daley, Robert, An American Saga, 1980, Random House, New York, , pages 1 ...

Flying Boats
A flying boat is a type of seaplane with a hull (watercraft), hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy. Though a flying boat’s fuselage provides buoyancy, it may also utilize under-wing Float (nautical), floats or wing-like hull projections (called sponsons) for additional stability. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during the Second World War. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used as mar ...

Pan American Airways
Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. The first airline to fly worldwide, it pioneered innovations such as jumbo jets and computerized reservation systems, and introduced the first American jetliner in 1958. Until its dissolution on December 4, 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word " Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. In the 1930s, under the leadership of American entrep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bomber
A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch aerial torpedo, torpedoes, or deploy air-launched cruise missiles. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. Bombs were first dropped from an aircraft during the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Seco ...

The aircraft series was named after Ilya Muromets, a hero in Russian folklore. The series was based on the Russky Vityaz or Le Grand, the world's first four-engined aircraft, designed by Igor Sikorsky. The Ilya Muromets aircraft as it appeared in 1913 was a revolutionary design, intended for commercial service with its spacious fuselage incorporating a passenger saloon and washroom on board. The Ilya Muromets was the world's first multi-engine aircraft in production and at least sixty were built.Sikorsky 1938, p. 96. During World War I, it became the first four-engine bomber to equip a dedicated strategic bombing unit.Massenkov et al. 1994, p. 23. This heavy bomber was unrivaled in the early stages of the war, as the Central Powers had no air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
