Lorraine 12f Courlis
The Lorraine 12F Courlis was a W-12 (broad arrow) aero engine introduced in France in 1929. It was not widely used. Design and development In 1926 Lorraine introduced a series of V-12 and W-12 engines with steel cylinders screwed into aluminium alloy engine blocks. There were two W-12s which shared the name Courlis (Curlew), the first of them was the 12E which provided from a swept volume of . This was followed by the larger 12F, giving from . The 12F was officially homologated on 21 August 1929 and displayed at the 1930 Paris Salon. Unlike the 12E, which powered many different aircraft types, the 12F was not so widely used.

Nieuport-Delage NiD
Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars. History Beginnings Originally formed as Nieuport-Duplex in 1902 for the manufacture of engine components the company was reformed in 1909 as the Société Générale d'Aéro-locomotion, and its products were marketed to the aviation industry, including ignition components. During this time they built their first aircraft, a small single-seat pod and boom monoplane. This was destroyed shortly after having been flown successfully, during the Great Flood of Paris in 1909 . A second design flew before the end of 1909 and had the essential form of modern aircraft, including an enclosed fuselage with the pilot protected from the slipstream and a horizontal tail whose aerodynamic force acted downwards, balancing the weight of the engine ahead of the centre of gravity, as opposed to upwards as on contemp ...

Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for sing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magneto
A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets. Hand-cranked magneto generators were used to provide ringing current in telephone systems. Magnetos were also adapted to produce pulses of high voltage in the ignition systems of some gasoline-powered internal combustion engines to provide power to the spark plugs. Use of such ignition magnetos for ignition is now limited mainly to engines without a low-voltage electrical system, such as lawnmowers and chainsaws, and to aircraft engines, in which keeping the ignition independent of the rest of the electrical system ensures that the engine continues running in the event of alternator or battery failure.

Carburetters
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Zenith Carburetters
The Zenith Carburetter Company Limited was a British company making carburettors in Stanmore Middlesex, founded in 1912 as a subsidiary of the French . In 1965, the company joined with its major pre-war rival Solex Carburettors, and over time, the Zenith brand name fell into disuse. The rights to the Zenith designs were owned by Solex UK (a daughter company of Solex in France). While better known for its much later products, Zenith produced carburettors that were standard equipment on some very early, brass era automobiles, including the Scripps-Booth. Products Zenith's best-known products were the Zenith-Stromberg carburettors used from 1965–1967 Humber Super Snipe Series Va/Vb, Humber Imperial, 1967–1975 Jaguar E-types, Saab 99s, 90s and early 900s, 1969–1972 Volvo 140s and 164s, 1966–1979 Hillman Minx, Hunter (Arrow), 1966–1970 Singer Gazelle/ Vogue (Arrow), 1967–1975 Sunbeam Alpine/ Rapier Fastback (Arrow), 1970–1981 Hillman/Chrysler/Talbot/S ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are clos ...

SAB AB-20
The SAB AB-20 was a large four engine twin boom French bomber built in the early 1930s as a development of the Dyle et Bacalan DB-70 airliner. It featured a lifting body of thick airfoil section between the inner engines. It was later modified for the attack role; a second aircraft, the AB-21, had different engines and cleaner aerodynamics but no more were built. Design The SAB AB-20 was a four-engine night bomber development of the three-engine Dyle et Bacalan DB-70 airliner. The change of manufacturer's name was the result of the financial failure of Dyle et Bacalan in 1929, followed by its immediate reappearance as SAB, who took over DB-70 development. The latter was built around a thick, wide chord airfoil centre section which provided generous internal space for passengers. The engines were mounted on this structure as were twin fuselages to carry the tail. The outer wings were of normal thickness and chord, and the cockpit and undercarriage were also attached to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potez 50
The Potez 50 or Potez 50 A2 was a French two seat military multi-rôle aircraft, first flown in 1931. It did not go into service but seven variants using five different engines were produced, one of them setting several speed with useful load records and another, the Potez 506, setting three altitude world records. Design The Potez 50 was a single bay sesquiplane. Both upper and lower wings were in two parts and were unswept with constant chord, though the trailing edge of the upper wing tapered outboard into rounded tips. The lower wing had a smaller chord as well as being about one third shorter. Both were built around two spruce and plywood box spars and were fabric covered. The outward leaning pairs of interplane struts were closer on the lower wing as its spars were closer together; additional wire bracing completed the structure. The upper wing was braced over the fuselage on parallel pairs of outward and slightly backward leaning cabane struts to the upper fusel ...

Hanriot A
Aéroplanes Hanriot et Cie. or simply 'Hanriot' was a French aircraft manufacturer with roots going back to the beginning of aviation. Founded by René Hanriot in 1910 as ''The Monoplans Hanriot Company Ltd.'' the company survived in different forms until 1916 when it established itself with the Hanriot-Dupont (HD.) fighters and observation aircraft. The company lasted through several takeovers and structural changes until in 1936 it merged with Farman to become the Société Nationale de Constructions Aéronautiques du Centre (SNCAC). 'Central Air Works' consortium. Hanriot aeroplanes included pre-war monoplanes with boat-like fuselages, the HD.1 and 2 World War I biplane fighters, the HD.14 trainer, and the H.220 series of twin-engined heavy fighters that eventually evolved in the SNCAC 600 fighter just before World War II. The company's main bases of operations were Bétheny (a suburb of Reims) Boulogne-Billancourt, Carrières-sur-Seine and Bourges. History René ...
