Fokker F.11
The Fokker F-11 was a luxury flying boat produced as an ' air yacht' in the United States in the late 1920s. Technically the aircraft was the Fokker Aircraft Corporation of America's Model 9. It was sold in North America as the Fokker F-11 and was offered in Europe as the Fokker B.IV. By the time the first six aircraft had been constructed, it was already evident that the design was not going to sell well. A few were sold, two to notable multi-millionaires; Harold Vanderbilt and Garfield Wood each purchasing one. One was bought by Air Ferries in San Francisco. The F-11A cost $40,000 but the price was slashed to $32,500 as the depression set in during 1930. The F-11 was a commercial failure. Development In 1922 Fokker designed the B. I flying boat, one of which was delivered to the Dutch Navy. The design was updated in 1926 as the Fokker B.III, which the Dutch Navy refused to purchase. The B.III was rebuilt as a civilian passenger plane, the B.IIIc. When that airplane faile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pusher Configuration
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific ( propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplan ...

Pratt & Whitney Wasp
The Pratt & Whitney Wasp was the civilian name of a family of air-cooled radial piston engines developed in the 1930s, 1940s, and 1950s.Gunston 1989, p.114. The Pratt & Whitney Aircraft Company (P&W) was founded in 1925 by Frederick B. Rentschler, who had previously been the President of Wright Aeronautical. He brought with him some of Wright's best designers and the new team quickly came up with their first design, the R-1340 Wasp. Wasp series * Pratt & Whitney R-1340 Wasp * Pratt & Whitney R-985 Wasp Junior * Pratt & Whitney R-1830 Twin Wasp * Pratt & Whitney R-1535 Twin Wasp Junior * Pratt & Whitney R-2000 Twin Wasp * Pratt & Whitney R-2180-E Twin Wasp E * Pratt & Whitney R-2800 Double Wasp * Pratt & Whitney R-4360 Wasp Major Note: the designations refer to the engine configurations as follows: "R" = Radial, followed by the approximate displacement in cubic inch The cubic inch (symbol in3) is a unit of volume in the Imperial units and United States customary ...

Pratt & Whitney R-1860 Hornet B
The Pratt & Whitney R-1860 Hornet B was a relatively uncommon aircraft engine. It was a development of Pratt & Whitney's earlier R-1690 Hornet and was basically similar, but enlarged in capacity from 1,690 to .Connors, p.79 Cylinder bore was increased by 1/8" and the crankshaft stroke by 3/8". Both engines were air-cooled radial engines, with a single row of nine cylinders. Design and development The cylinder and valve design was typical for Pratt & Whitney, a simple design with two large valves driven by pushrods. The enlarged engine was designed by George Willgoos and was first available in 1929.Smithsonian The Hornet series of engines was similar to the Wasp, but larger. In both series a nine-cylinder single-row engine was later supplemented by an enlarged fourteen cylinder engine, with two rows of the same cylinders, but reduced in number to seven per row to aid cooling to the rear row (it was never made into a larger, 18 cylinder radial like the related Wasp was).

Fairchild 91
The Fairchild 91, (a.k.a. A-942), was a single-engine eight-passenger flying boat airliner developed in the United States in the mid-1930s.Taylor, Michael J.H. . ''Jane's Encyclopedia of Aviation”. Studio Editions. London. 1989. Design Fairchild designed the aircraft in response to a Pan American Airways request for a small flying boat to operate on their river routes along the Amazon and Yangtze. The result was a conventional high-wing cantilever monoplane with its radial engine mounted above the wing in a streamlined nacelle. Before construction of the prototype was complete, however, Pan American no longer required the aircraft to operate in China, and Fairchild optimised the design for the Brazilian tropics. Operational history After the first two aircraft were delivered, Pan American cancelled the remaining four aircraft of its order as they no longer needed any for China and the two aircraft were capable of handling the Amazon River. The sole A-942-B was specially bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-43
The Sikorsky S-43 (sometimes referred to as the Baby Clipper) was a 1930s American twin-engine amphibious flying boat monoplane produced by Sikorsky Aircraft. Design and development The S-43 first flew in 1935, and was a smaller version of the Sikorsky S-42 "Clipper". It accommodated between 18 and 25 passengers, with a separate forward cockpit for the two crew.Simpson, 2001, p. 499 The S-43 was known as the "Baby Clipper" in airline service. On April 14, 1936, an S-43 with a payload, piloted by Boris Sergievsky, set an altitude record for amphibious aircraft when it reached an altitude of over Stamford, Connecticut with designer Igor Sikorsky aboard. Approximately 53 S-43s were built, including examples of the twin-tailed S-43B. Operational history The S-43 was used primarily by Pan American World Airways for flights to Cuba and within Latin America. Inter-Island Airways of Hawaii (Inter-Island changed its name to Hawaiian Airlines in 1941) was the launch customer for th ...

Douglas Dolphin
The Douglas Dolphin is an American amphibious flying boat. While only 58 were built, they served a wide variety of roles including private air yacht, airliner, military transport, and search and rescue. Design and development The Dolphin originated in 1930 as the "Sinbad," a pure flying boat without wheels. The Sinbad was intended as a luxurious flying yacht. Undaunted by the lack of demand, Douglas improved the Sinbad in 1931 so that it was amphibious, and could land on water or land. The improved aircraft was named "Dolphin", however this did not represent the end of development, as many detail improvements were made, including an increase in the length of over a foot and changes made to the empennage, engine nacelles and wings. The Great Depression had curtailed demand for such extravagance as a "flying yacht", but Douglas managed to interest the United States Coast Guard who not only bought the Sinbad, but 12 Dolphins.Rumerman, Judy"Douglas Aircraft Builds the DC-1 and DC-2." ...

Loening Model 23
The Loening S-1 Flying Yacht, also called the Loening Model 23, was an early light monoplane flying boat designed in the United States by Grover Loening in the early 1920s.Taylor 1989, 609 The aircraft won the 1921 Collier Trophy. Design and development The S-1 Flying Yacht was a high-wing, strut-braced monoplane with the engine mounted pusher-fashion in a nacelle atop the wing. The cabin was semi-enclosed, featuring side windows but no roof, and was located immediately ahead of the wing. Twin tails were fitted, carrying a common stabiliser in a high position. The construction was unusual, in that rather than the flying boat hull being integral with the fuselage, the Model 23's hull was a large, separate pontoon mounted directly underneath a fuselage that was a separate structure."The Loening Model 23 Flying Boat" This was intended to combine the safety of a floatplane design with the low parasitic drag of a conventional flying boat Grover Loening was awarded the 1921 Aero ...

Duralumin
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age hardening, age-hardenable aluminium alloys. The term is a combination of ''Dürener'' and ''aluminium''. Its use as a trade name is obsolete. Today the term mainly refers to aluminium–copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 aluminium alloy, 2014 and 2024 aluminium alloy, 2024 alloys used in airframe fabrication. History Duralumin was developed by the German metallurgist Alfred Wilm at Dürener Metallwerke Aktiengesellschaft, AG. In 1903, Wilm discovered that after quenching, an aluminium alloy containing 4% copper would harden when left at room temperature for several days. Further improvements led to the introduction of duralumin in 1909. The name is mainly used in popular science, pop-science to describe all Al-Cu alloys system, or '2000' series, as designated throug ...
