DGA-15
The Howard DGA-15 was a single-engine civil aircraft produced in the United States by the Howard Aircraft Corporation from 1939 to 1944. After the United States' entry into World War II, it was built in large numbers for the United States Navy and also served various roles in the United States Army Air Forces. Design and development The Howard Aircraft Company (later Howard Aircraft Corporation) was formed in 1936 to build commercial derivatives of the Howard DGA-6 (named ''Mister Mulligan''),Bushell 1987, p.42. a successful four-seat racing aircraft which had won both the Bendix and the Thompson Trophies in 1935, the only aircraft ever to win both races.Bushell 1987, pp.40-41. These successes did indeed bring the DGA series much attention, and Howard produced a series of closely related models differing mainly in the engine type, consisting of the DGA-7, -8, -9, -11 and -12. Offering high performance and being comprehensively equipped, despite a high purchase price (with the D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howard Aircraft Corporation
Howard Aircraft Corporation was a small United States aircraft manufacturer in the 1930s and 1940s. The factory was initially on the south side of Chicago Municipal Airport at 5301 W. 65th Street; during World War II a second plant was opened at DuPage Airport west of Chicago. Early history Designer Ben "Benny" Howard, after his success with smaller aircraft, designed and built the ''Mister Mulligan'', a successful 4-seat cross-country racer that also proved a worthy closed-course mount. While Beechcraft had designed and produced their Staggerwing for the private market, that aircraft was mechanically and structurally complex; Howard instead chose to emulate (on a larger scale) the simpler Monocoupe design. After winning both the Bendix and Thompson trophies in 1935, Howard turned to the formation of the Howard Aircraft Company - later Howard Aircraft Corporation on January 1, 1937, to produce commercial versions of the now-famous DGA cabin monoplanes, each custom-built by Ben Ho ...

These engines have a displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a bore and stroke of , giving a 27% lesser total displacement. The Wasp Junior used ...

Howard DGA-11
The Howard DGA-8, DGA-9, DGA-11, and DGA-12 were a family of four-place, single-engine, high-wing light monoplanes built by the Howard Aircraft Corporation, Chicago, Illinois from 1936. Development The various models were distinguished by different engine choices and detail changes, and were built and sold in parallel to each other. A number of examples were built as one type and converted to another during their lifetimes. The DGA-11, powered by a nine-cylinder Pratt & Whitney Wasp Junior radial engine, was purportedly the fastest four-seat civil aircraft of the late 1930s, able to achieve a top speed of about . A favorite of the high society and Hollywood circles, the DGA-11 cost about $16,500 in 1938. These aircraft were a direct developments of the famous Howard racing plane ''Mister Mulligan''. Designer/pilot Ben Howard's "DGA" prefix stood for "Damned Good Airplane". History The DGA-6's racing success brought the DGA series much attention, and in its various permutations, ...

Howard DGA-6
The Howard DGA-6 was a pioneer racing plane, nicknamed "Mister Mulligan". It was the only airplane ever designed for the specific purpose of winning the Bendix Trophy. The plane was designed and developed by Ben Howard and Gordon Israel, who later became an engineer for the Grumman Aircraft Engineering Corporation. ''Mister Mulligan'' was designed to fly the entire length of the race nonstop and at high altitude. Neither had ever been done before. ''Mister Mulligan'' won the trophy, and thus changed the way in which long distance airplanes were designed. History The Bendix Trophy was a cross-country race from the west coast to the site of the National Air Races in Cleveland, Ohio, and typically was the starting event of the week-long aviation festival. The Thompson Trophy was awarded to the winner of the unlimited division in closed-course pylon racing at the National Air Races. The sole original DGA-6 was constructed in 1934 in the defunct factory of the American Eagle-Linc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wright R-760
The Wright R-760 Whirlwind was a series of seven-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of 756 in³ (12.4 L) and power ratings of 225-350 hp (168-261 kW). Design and development Wright introduced the J-6 Whirlwind family in 1928 to replace the nine-cylinder R-790 series. The J-6 family included varieties with five, seven, and nine cylinders. The seven-cylinder version was originally known as the J-6 Whirlwind Seven, or J-6-7 for short. The U.S. government designated it as the R-760; Wright later adopted this and dropped the J-6 nomenclature. Like all the members of the J-6 Whirlwind family, the R-760 had larger cylinders than the R-790. The piston stroke of 5.5 in (14.0 cm) was unchanged, but the cylinder bore was expanded to 5.0 in (12.7 cm) from the R-790's bore of 4.5 in (11.4 cm). While the R-790 was naturally aspirated, the ...

Bush Airplane
A bush airplane is a general aviation aircraft used to provide both scheduled and unscheduled passenger and flight services to remote, undeveloped areas, such as the Canadian north or bush, Alaskan tundra, the African bush, or savanna, Amazon rainforest or the Australian Outback. They are used where ground transportation infrastructure is inadequate or does not exist. Common traits Since a bush plane is defined by how it is used, a wide variety of different aircraft with different configurations have been used over the years as such. However, experience has shown certain traits to be desirable, and so they appear frequently, especially on aircraft specifically designed as bush planes. None of these traits are mandatory - merely they are commonly seen features of bush planes. * The undercarriage is designed to be fitted with floats, skis or wheel/skis to permit operation from water or snow—primarily for Canadian, Alaskan and Russian use. * High wings ease loading and unloadi ...
