Lorraine Algol
The Lorraine 9N Algol was a French 9-cylinder radial aeroengine built and used in the 1930s. It was rated at up to , but more usually in the range. Design and development The Algol was a conventionally laid out radial engine, with nine cylinders in a single row. The crankcase was a barrel-shaped aluminium alloy casting, with an internal integral diaphragm which held the front crankshaft bearing. Forward of the diaphragm there was an integrally cast cam-gear case for the double track cam-ring. The reduction gear was housed under a domed casing attached to the front of the crankcase. Flange-mounted steel barrels were bolted to the crankcase and enclosed with cast aluminium alloy, screwed-on, cylinder head with integral cooling fins. The pistons were also made of aluminium alloy and had floating gudgeon pins. The nine pistons drove the single throw crankshaft via one channel-section master rod and eight circular section auxiliary rods. The master rod had an integral, split ...

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

FBA 290
__NOTOC__ The Franco-British Aviation Model 290 was a French four-seat amphibian flying boat built by the Franco-British Aviation Company (FBA) as a replacement for the Model 17 in French naval service. Development The FBA Company was requested to design a successor to the Model 17 in the liaison and training role. The company used the experience gained in the Model 270 and 271 and produced the Model 290. The Model 290 was a biplane amphibian with a single radial engine driving a pusher propeller. It had room for four persons in the forward part of the hull. The Model 290 flew for the first time in April 1931 powered by a 300 hp (224 kW) Lorraine engine. A further example, the Model 291 was built with a Gnome-Rhône radial engine. The French Navy was looking for a VIP transport and ordered eight aircraft based on the Model 291 and designated the Model 293 (with a Lorraine engine) and the Model 294 (with a Gnome-Rhône engine). The navy aircraft were used as executi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudron C
The Société des Avions Caudron was a French aircraft company founded in 1909 as the Association Aéroplanes Caudron Frères by brothers Gaston and René Caudron. It was one of the earliest aircraft manufacturers in France and produced planes for the military in both World War I and World War II. From 1933 onwards, it was a subsidiary of Renault. Alphonse (Gaston) (1882–1915) and René Caudron (1884–1959) Born in Favières, Somme to parents who farmed nearby in Romiotte, the Caudron brothers were educated at a college in Abbeville. Gaston, as Alphonse was always known, intended to become an engineer but his education was cut short by health problems; René was interested in the development of mechanics and was a sportsman. After military service in an artillery regiment, they returned to work on the farm. They began to build their first aircraft, a large biplane, in August 1908. Initially unable to obtain an engine, they flew it as a glider, towed by a horse, and tested it t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bernard 160
The Bernard 160 was a three engine, multi-role monoplane designed in the early 1930s to meet a French government call for aircraft suited to policing and medical duties in its African colonies. Two prototypes were built and tested, but no further orders were placed. Design and development By 1928 there was significant government aviation activity in French African colonies. Initially this involved the Breguet 14, a largely metal-framed World War I bomber that was gradually replaced by the newer but wooden Potez 25. It was soon realised that in the hot humid climates, metal-framed aircraft were more durable and required less maintenance; as a result a new category for French aircraft, the Colonial type, was established. In 1930 the Air Ministry issued a programme with design criteria for both single and multi-engine types. The latter, designated ''Col 3'', was required to have three engines, providing the ability to maintain an altitude of with one engine out. It was to have fou ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ai ...

Carburetter
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 an ...

Epicyclic Gear
An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates the planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an ''annular gear''. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid. The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a ''planetary gear train''.J. J. Uicker, G. R. Pennock and J. E.
