Curtiss H-1640 Chieftain
The Curtiss H-1640 Chieftain was an unusual American 12-cylinder radial aero engine designed and built by the Curtiss Aeroplane and Motor Company in the mid-1920s.Gunston 1989, p. 46 Design and development The H-1640 was an air-cooled 12 cylinder two-row radial with the cylinder rows aligned rather than staggered as in most multi-row radials. One piece cylinder heads shared a single overhead camshaft and the propeller was directly driven. By aligning the cylinders the diameter of the engine was less than more conventional radial engines, and it was thought that the use of a Townend ring could make the engine more aerodynamically efficient than an inline engine. The engine first ran in 1927. The H-1640 was the first airworthy 'inline radial' and was sponsored for flight testing in a range of aircraft by the U.S. Government. Among the types selected were the Thomas-Morse XP-13 and the Curtiss XO-18. Cooling problems with the rear cylinders caused the project to be canceled ...

Armstrong Siddeley Hyena
The Armstrong Siddeley Hyena was a British aero engine developed by Armstrong Siddeley. Designed in the 1930s, it was an unusual experimental radial engine with inline cylinder banks. It was flown using an Armstrong Whitworth A.W.16 fighter aircraft as a test bed. Unresolved problems with cooling of the rear cylinders prevented the engine from going into production. Few details of this engine survive as company records were lost.Lumsden 2003, p.76. Armstrong Siddeley in-line radial engines The Hyena arrangement of cylinder banks arranged as a radial engine was continued with further designs, but with little commercial success, with only the Deerhound and Hyena being built. ;Hyena: 15 cylinders (5 banks of 3 cyl.) ;Terrier: 14 cylinders (7 banks of 2 cyl.) ;Deerhound: 21 cylinders (7 banks of 3 cyl.) ;Wolfhound: 28 cylinders (7 banks of 4 cyl.) ;Boarhound: 24 cylinders (6 banks of 4 cyl.) ;Mastiff: 36 cylinders (9 banks of 4 cyl.)

Radial Engines
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added in ...

Curtiss Aircraft Engines
Curtiss Aeroplane and Motor Company (1909 – 1929) was an American aircraft manufacturer originally founded by Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation. History Origin In 1907, Glenn Curtiss was recruited by the scientist Dr. Alexander Graham Bell as a founding member of Bell's Aerial Experiment Association (AEA), with the intent of establishing an aeronautical research and development organization. According to Bell, it was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p 13. In 1909, shortly before the AEA was disbanded, Curtiss partnered with Augustus Moore Herring to form the Herring-Curtiss Company.Gunston 1993, p. 87. It was renamed the Curtiss Aeroplane Company in 1910 and reorganized in 1912 after being taken-o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curtis H 1640 Engine
Curtis or Curtiss is a common English given name and surname of Anglo-Norman origin from the Old French ''curteis'' (Modern French ''courtois'') which derived from the Spanish Cortés (of which Cortez is a variation) and the Portuguese and Galician Cardoso. The name means "polite, courteous, or well-bred". It is a compound of ''curt-'' "court" and ''-eis'' "-ish". The spelling ''u'' to render in Old French was mainly Anglo-Norman and Norman, when the spelling ''o'' was the usual Parisian French one, Modern French ''ou'' ''-eis'' is the Old French suffix for ''-ois'', Western French (including Anglo-Norman) keeps ''-eis'', simplified to ''-is'' in English. The word ''court'' shares the same etymology but retains a Modern French spelling, after the orthography had changed.T. F. Hoad, ''English Etymology'', Oxford University Press paperbook 1993. p. 101a It was brought to England (and subsequently, the rest of the Isles) via the Norman Conquest.

Thomas-Morse XP-13 Viper
The XP-13 Viper was a prototype biplane fighter aircraft designed by the American company Thomas-Morse Aircraft Corporation. The airplane was delivered to the United States Army in 1929, but they did not adopt it. Design and development This aircraft was one of several B. Douglas Thomas designs built in hopes of a production contract from the Army, following the successful Thomas-Morse MB-3 of 1919. Financed by the company, and named the "Viper", it was officially purchased by the Army in June 1929 and designated "XP-13". The XP-13 fuselage had a corrugated aluminum skin built over a metal frame; the flying surfaces were also metal-framed, but covered with the traditional fabric. While designed to use the 600 hp Curtiss H-1640-1 Chieftain engine, (a novel 12-cylinder two-row air-cooled radial with the rear cylinders directly behind the front cylinders rather than staggered as normal in a two-row radialGunston 1986, p.46.) for which the XP-13 incorporated a complex sys ...

Curtiss P-6 Hawk
The Curtiss P-6 Hawk is an American single-engine biplane fighter introduced into service in the late 1920s with the United States Army Air Corps and operated until the late 1930s prior to the outbreak of World War II. Design and development The Curtiss Aeroplane and Motor Company (which became the Curtis-Wright Corporation (15 July 1929) supplied the USAAC with P-6s beginning in 1929. Operational history A fast and highly maneuverable aircraft for its time, the XP-6 prototype took 2nd place in the 1927 U.S. National Air Races, and the XP-6A with wing surface radiators took first place, at 201 mph (323 km/h). The P-6 was flown in a variety of paint schemes depending on the squadron, the most famous being the "Snow Owl" markings of the 17th Pursuit Squadron based at Selfridge Field near Detroit, Michigan. The P-6Es served between 1932 and 1937 with the 1st Pursuit Group (17th and 94th PS) at Selfridge, and with the 8th Pursuit Group (33rd PS) at Langley Field, ...

Curtiss YP-20
The Curtiss YP-20 was an American biplane fighter project developed by Curtiss for the United States Army Air Service. Design and development In 1929, three Curtiss P-11 Hawks were ordered with 600 hp (447 kW) Curtiss H-1640 Chieftain engines. These proved a failure, and before completion, the third was converted to use a 9-cylinder 575 hp (429 kW) Wright Cyclone, being completed as the YP-20. Testing with the R1820 was prolonged, so the Army's intention to promptly switch to a Curtiss V-1570 Conqueror engine and redesignate the aircraft XP-22 was dropped; another P-11 was chosen for that instead. Except for the engine change and its Townend ring cowling, the YP-20 was not drastically different from the P-6 from which both it and the P-11 derived, though the YP-20 had more fin and less rudder area, and featured a steerable tailwheel, rather than the original skid.Fitzsimons, p.1255. Later, a crankcase cover, gear strut fairings, and wheel pants were added ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss XP-22 Hawk
The Curtiss XP-22 Hawk was a 1930s American experimental biplane fighter built by Curtiss for evaluation by the United States Army Air Service. Design and development In 1929, the AAC ordered three P-11 Hawks for testing of the 600 hp (447 kW) H-1640 Chieftain engine. This engine proved a failure, and before completion, one of the three was converted to use a 9-cylinder 575 hp (429 kW) Cyclone, being completed as the YP-20. Testing with the R-1820 was prolonged, so the Army acquired another of the three P-11s, instead. This became the XP-22. A number of changes were made for installing the 700 hp (520 kW) Curtiss V-1570 Conqueror engine. The radiator was relocated, a new cowl was fitted, and the tail was given more fin and less rudder area, and featured a steerable tailwheel, rather than the original skid. For these changes, Curtiss charged only US$1.Fitzsimons 1978, p. 1255. During testing, the XP-22 underwent a number of alterations and impr ...
