Siddeley Tiger
The Siddeley Tiger was an unsuccessful British aero engine developed shortly after the end of World War I by Siddeley-Deasy. Problems encountered during flight testing caused the project to be cancelled. Design and development Developed using two modified cylinder banks from the Siddeley Puma, the Tiger was a liquid-cooled 60-degree V12 engine with the advanced feature of an electric starter motor protected by a friction clutch. A reduction gear arrangement was provided for the propeller drive with a ratio of 0.559:1. The company claimed a power output of 600 hp (447 kW) but this was regarded as optimistic.Gunston 1989, p.18. Flight testing by a Royal Aircraft Establishment test pilot, Frank Courtenay, revealed problems and his opinion of the engine was low as the following quote shows: Application and cancellation The Tarrant Tabor, a giant triplane bomber was designed to use the Tiger but redesigned to use other engines when it became clear the Tiger would not ...

Siddeley-Deasy Siniai
The Siddeley-Deasy Sinaia, also known as the Armstrong Whitworth Sinaia was a twin-engined biplane day bomber with gunners in rearwards extensions of the engine nacelles. Two examples were ordered by the Air Ministry but only one was completed. Development The Sinaia was the third and last aircraft design produced by the team led by John Lloyd and F. M. Green at Siddeley-Deasy before they were rebadged by merger as the Sir W. G. Armstrong Aircraft Company. Indeed, by the time it flew in 1921 this change had taken effect. It was designed to meet an Air Ministry requirement for a day bomber. A large twin-engined biplane, its most interesting feature was the arrangement of the defensive armament. The Sinaia's engines were in nacelles mounted on the top of the lower wings and these nacelles were extended rearwards and upwards. Each extension housed a gunner's cockpit at its extremity, fitted with a gun ring. From these positions the gunners would have been able to defend bot ...

Carburetor
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 ...

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] |
Radial Engine
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 i ...

Armstrong Siddeley
Armstrong Siddeley was a British engineering group that operated during the first half of the 20th century. It was formed in 1919 and is best known for the production of luxury vehicles and aircraft engines. The company was created following the purchase by Armstrong Whitworth of Siddeley-Deasy, a manufacturer of fine motor cars that were marketed to the top echelon of society. After the merge of companies, this focus on quality continued throughout in the production of cars, aircraft engines, gearboxes for tanks and buses, rocket and torpedo motors, and the development of railcars. Company mergers and takeovers with Hawker Aviation and Bristol Aero Engines saw the continuation of the car production which ceased in August 1960. The company was absorbed into the Rolls-Royce conglomerate which was interested in the aircraft and aircraft engine business. Eventually, the remaining spares and all motor car interests were sold to the Armstrong Siddeley Owners Club Ltd, which now own ...

William Beardmore And Company
William Beardmore and Company was a British engineering and shipbuilding conglomerate based in Glasgow and the surrounding Clydeside area. It was active from 1886 to the mid-1930s and at its peak employed about 40,000 people. It was founded and owned by William Beardmore, later Lord Invernairn, after whom the Beardmore Glacier was named. History Forged steel castings, armour plate and naval guns The Parkhead Forge, in the east end of Glasgow, became the core of the company. It was established by Reoch Brothers & Co in 1837 and was later acquired by Robert Napier in 1841 to make forgings and iron plates for his new shipyard in Govan. Napier was given the contract to build , sister ship to the Royal Navy's first true ironclad warship, . Parkead was contracted to make the armour for her, but failed, so the manager, William Rigby called in William Beardmore Snr, who at the time was superintendent of the General Steam Navigation Company in Deptford, to help. Beardmore became a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarrant Tabor
The Tarrant Tabor was a British triplane bomber designed towards the end of the First World War and was briefly the world's largest aircraft. It crashed, with fatalities, on its first flight. Development The Tabor was the first and only aircraft design produced by W.G Tarrant Ltd, a well-known property developer and building contractor at Byfleet, Surrey, which had been subcontracted to build aircraft components during the First World War. In late 1917 Tarrant assembled a design team, led by Walter Barling, hired from the Royal Aircraft Factory and Marcel Lobelle, hired from Martinsyde to design a very large long-range heavy bomber, capable of bombing Berlin. Captain Percy Townley Rawlings formerly of the RNAS was general manager of the department. Construction was primarily in wood with conventional tri-plane strut-braced wings and a monocoque fuselage built up from ply veneers. Circular Warren girders formed of wood joined with longerons formed the fuselage structure. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
