J2F
The Grumman J2F Duck (company designation G-15) is an American single-Reciprocating engine, engine amphibious aircraft, amphibious biplane. It was used by each major branch of the United States Armed Forces, U.S. armed forces from the mid-1930s until just after World War II, primarily for Utility aircraft, utility and air-sea rescue duties. It was also used by the Argentine Navy, who took delivery of their first example in 1937. After the war, J2F Ducks saw service with independent civilian operators, as well as the armed forces of Colombia and Mexico. The J2F was an improved version of the earlier Grumman JF Duck, JF Duck, the main differences being a longer Float (nautical), float and a more-powerful engine (900 horsepower versus 775).Allen 1983, p. 49. Development The J2F-1 Duck first flew on 2 April 1936, powered by a 750 hp (559 kW) Wright R-1820 Cyclone, and was delivered to the United States Navy, U.S. Navy on the same day. The J2F-2 had an uprated Wright Cycl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman JF Duck
The Grumman JF "Duck" was an American single-engine amphibious biplane built by Grumman for the United States Navy during the 1930s. The J2F Duck was an improved version of the JF, with its main difference being a longer float.Allen 1983, p. 49. Design and development The Grumman JF Duck was manufactured from 1934 until 1936, when production switched to the J2F Duck and later variants.Jordan, Corey C."Grumman's Ascendency: Chapter Two." ''Planes and Pilots Of World War Two,'' 2000. Retrieved: 22 July 2011. The more obvious external appearance clue to distinguish a JF from an early J2F is the deletion of the inter-aileron strut between the wings on the J2F; less noticeable perhaps is the J2F's slightly longer rear fuselage/ float joining fillet beneath the tail. The Duck's main pontoon was part of the fuselage, almost making it a flying boat, although it appears more like a standard aircraft with an added float. The XJF-1 prototype first flew on 24 April 1933 piloted by Grumma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia Aircraft Corp
The Columbia Aircraft Corporation was an American aircraft manufacturer, which was active between 1927 and 1947. History Columbia Aircraft was founded in December 1927 by Charles A. Levine as chairman and the aircraft designer Giuseppe Mario Bellanca as president. The initial name used was Columbia Air Liners, Inc. The aircraft factory was established at Hempstead, New York. Levine hired pilots Bert Acosta, Eroll Boyd, John Wycliff Isemann, Burr Leyson, and Roger Q. Williams at $200 a week to perform a series of publicity record attempts for the company. The most ambitious project for the company was the "Uncle Sam". Main participant were John Carisi as motor expert, Edmond Chagniard, French designer and airplane constructor, and Alexander Kartveli as technical engineer from Georgia. The $250,000 prototype was brought to market at the height of the depression. It was sold at auction for $3,000 to pay back hangar rent. The "Uncle Sam" and two other Triads were destroyed sh ...

Grumman FF
The Grumman FF "Fifi" (company designation G-5) was an American biplane fighter aircraft operated by the United States Navy during the 1930s.Eden and Moeng 2002, p. 762. It was the first carrier aircraft with retractable landing gear.Winchester 2002, p. 21. It was produced under licence in Canada and known as the Goblin in Canadian service and Delfín (English: "Dolphin") in Spanish service. Design and development The ''FF-1'' was Grumman’s first complete aircraft design for the US Navy. The Navy had asked Grumman if their retractable landing gear made for the O2U-1 Scout planes could be retrofitted to the Navy's Boeing F4B-1 fighters; instead Grumman proposed a new fighter design. The prototype ''XFF-1'' (serial number A8878) was built to a contract placed on 22 April 1931, first flying on 29 December of that year,Cacutt 1989, p. 155–162.Swanborough and Bowers 1976, p. 195. a two-seat design, with an enclosed cockpit, fuselage of all-metal construction, and wings covered l ...

Amphibious Aircraft
An amphibious aircraft or amphibian is an aircraft (typically fixed-wing) that can take off and land on both solid ground and water, though amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes ( flying boats and floatplanes) which are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared to planes designed specifically for land-only or water-only operation. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up. Design Floatplanes often have floats that are interchangeable with wheeled landing gear (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the DHC Otter, incorporate retractable wheels within their floats. Many amphibian aircraft are of the flying boat type. These aircraft, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wright R-1820
The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25. Design and development The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s. The R-1820 was built under license by Lycoming, Pratt & Whitney Canada, and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov '' OKB'' was formed to metricate the American specification powerplant for Soviet government-factory production as the '' M-25'', with the R-1820's general design features used by the Shvetsov design bureau for many of their fut ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and ...
