De Havilland Gipsy Major
The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous de Havilland Tiger Moth, Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types. Engines were produced by de Havilland in the UK and by the Australian arm of the company, de Havilland Australia, the latter modifying the design to use Imperial units, imperial measures rather than the original Metric system, metric measurements. Design and development The engine was a slightly modified Gipsy III, which was effectively a de Havilland Gipsy engine modified to run inverted so that the cylinders pointed downwards below the crankcase. The Major was also bored-out (118 mm from 114 mm) compared to the Gipsy III, increasing displacement from 5 L to 6.1 L. The inverted configuration allowed the Propeller (aircraft), propeller shaft to be kept in a high position without having ...

Crankcase
A crankcase is the housing in a reciprocating engine, piston engine that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the Cylinder (engine), cylinder(s). This design of the engine does not include an oil sump in the crankcase. Four-stroke engines typically have an oil sump at the bottom of the crankcase and the majority of the engine's oil is held within the crankcase. The fuel/air mixture does not pass through the crankcase, though a small amount of exhaust gasses often enter as "blow-by" from the combustion chamber, particularly in engines with worn rings. The crankcase often forms the upper half of the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals. An ''open-crank'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Motors Company
Continental Motors Company was an American manufacturer of internal combustion engines. The company produced engines as a supplier to many independent manufacturers of automobiles, tractors, trucks, and stationary equipment (such as pumps, generators, and industrial machinery drives) from the 1900s through the 1960s. Continental Motors also produced automobiles in 1932–1933 under the name Continental Automobile Company. The Continental Aircraft Engine Company was formed in 1929 to develop and produce its aircraft engines, and would become the core business of Continental Motors, Inc. History In 1905, Continental Motors was founded with the introduction of a four-cylinder, four-stroke L-head engine utilizing a single camshaft. In August 1929, the Continental Motors Company formed the Continental Aircraft Engine Company as a subsidiary to develop and produce its aircraft engines. Continental Motors entered into the production of automobiles rather indirectly. Continental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blackburn Cirrus Major
The Blackburn Cirrus Major is a British, inline-four aircraft engine which was developed in the late 1930s, but continued development and production into the 1940s and post war. Design and development The Blackburn Cirrus Major started life as a clean-sheet replacement for the original 1920s Cirrus and Hermes series of upright inline four-cylinder air cooled aircraft engines originally designed by Frank Halford for the early DH60 de Havilland Cirrus Moth and which had been in production by the Aircraft Disposal Company (ADC) and later Cirrus Aero Engine Limited, which itself evolved into the Cirrus-Hermes Engineering Company. C. S. Napier, son of engine designer Montague Napier, was Technical Director and Chief Designer for Cirrus-Hermes Engineering when he began work on two new engines, the Cirrus minor and the larger Cirrus Major. The engines were still under development when the company was bought by the Blackburn Aeroplane & Motor Company, moved to a new factory at Br ...

Royal Air Force
The Royal Air Force (RAF) is the Air force, air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the World War I, First World War on 1 April 1918, on the merger of the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allies of World War I, Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has played History of the Royal Air Force, a significant role in Military history of the United Kingdom, British military history. In particular, during the Second World War, the RAF established Air supremacy, air superiority over Nazi Germany's Luftwaffe during the Battle of Britain, and led the Allied strategic bombing effort. The RAF's mission is to support the objectives of the British Ministry of Defence (United Kingdom), Ministry of Defence (MOD), which are to "provide the capabilities nee ...

De Havilland Canada DHC-1 Chipmunk
The de Havilland Canada DHC-1 Chipmunk (or Chippie) is a tandem, two-seat, single-engined primary trainer aircraft designed and developed by Canadian aircraft manufacturer de Havilland Canada. It was developed shortly after the Second World War and sold in large numbers during the immediate post-war years, being typically employed as a replacement for the de Havilland Tiger Moth biplane. The Chipmunk was the first postwar aviation project conducted by de Havilland Canada. It performed its maiden flight on 22 May 1946 and was introduced to operational service that same year. During the late 1940s and 1950s, the Chipmunk was procured in large numbers by military air services such as the Royal Canadian Air Force (RCAF), Royal Air Force (RAF), and several other nations' air forces, where it was often utilised as their standard primary trainer aircraft. The type was produced under licence by de Havilland in the United Kingdom, who would produce the vast majority of Chipmunks, as w ...

V-engine
A V engine, sometimes called a Vee engine, is a common configuration for internal combustion engines. It consists of two cylinder banks—usually with the same number of cylinders in each bank—connected to a common crankshaft. These cylinder banks are arranged at an angle to each other, so that the banks form a "V" shape when viewed from the front of the engine. V engines typically have a shorter length than equivalent inline engines, however the trade-off is a larger width. V6, V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively. History The first V engine, a two-cylinder V-twin, was designed by Wilhelm Maybach and used in the 1889 Daimler Stahlradwagen automobile. The first V8 engine was produced in 1903, in the form of the Antoinette engine designed by Léon Levavasseur for racing boats and airplanes. The first V12 engine was produced the following year by Putney Motor Works in London, again for use in racin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Havilland Albatross
The de Havilland DH.91 Albatross was a four-engined British transport aircraft of the 1930s manufactured by de Havilland, de Havilland Aircraft Company Limited. Seven aircraft were built between 1938 and 1939. Development The DH.91 was designed in 1936 by Arthur Ernest Hagg, A. E. Hagg to List of Air Ministry specifications, Air Ministry specification 36/35 for a transatlantic mail plane. The aircraft was notable for the plywood, ply-balsa-ply sandwich construction of its fuselage, later used in the de Havilland Mosquito bomber. Another unique feature was a cooling system for the air-cooled engines that allowed nearly ideal streamlining of the engine mounting. The first Albatross flew on 20 May 1937. The second prototype broke in two during overload tests, but was repaired with minor reinforcement. The first and second prototypes were operated by Imperial Airways. Although designed as a mail plane, a version to carry 22 passengers was developed, with the main differences being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
