X Engine
An X engine is a piston engine with four banks of cylinders around a common crankshaft, such that the cylinders form an "X" shape when viewed from front-on. The advantage of an X engine is that it is shorter than a V engine of the same number of cylinders, however the drawbacks are higher weight and complexity as compared to a radial engine. Therefore the configuration has been rarely used. Several of the X engine designs were based on combining two V engines. Examples Only two examples of X engines are known to have reached production. The first was the 1939–1942 Rolls-Royce Vulture, a X-24 aircraft engine which was built using two Rolls-Royce Peregrine V12 engines. The Rolls-Royce Vulture was briefly used in the Avro Manchester heavy bomber, before engine failures caused it to be replaced by the Avro Lancaster (powered by the Rolls-Royce Merlin V12 engine). The other production X engine is the ChTZ Uraltrac 12N360 X-12 engine, first produced in 2015, and used in the Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Armata Universal Combat Platform
The "Armata" Universal Combat Platform (russian: Армата) is a Russian advanced next generation modular heavy military tracked vehicle platform. The Armata platform is the basis of the T-14 (a main battle tank), the T-15 (a heavy infantry fighting vehicle), a combat engineering vehicle, an armoured recovery vehicle, a heavy armoured personnel carrier, a tank support combat vehicle, and several types of self-propelled artillery, including the 2S35 Koalitsiya-SV under the same codename based on the same chassis. It is also intended to serve as the basis for artillery, air defense, and NBC defense systems. The new "Armata" tank platform is meant to replace the older Russian main battle tanks and APCs that are currently used by the Russian military. Origin of designation The combat platform is formally designated as "prospective family of heavy unified battlefield platforms". The name "Armata" derives from the plural of the Latin word which refers to weapons of war, and was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piston Engine Configurations
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinder Pneumatic cylinders (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Like hydraulic cylinders, something forces a piston to move in the desire ...s, among other similar mechanisms. It is the moving component that is contained by a cylinder (engine), cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering Porting (engine)#Two-stroke porting, ports in the cylinder. __TOC__ Piston ...

W Engine
A W engine is a type of piston engine where three or four cylinder banks use the same crankshaft, resembling the letter W when viewed from the front. W engines with three banks of cylinders are also called "broad arrow" engines, due to their shape resembling the British government broad arrow property mark. W engines are less common than V engines. Compared with a V engine, a W engine is typically shorter and wider. W3 engines One of the first W engines was the Anzani 3-cylinder, built in 1906, to be used in Anzani motorcycles. It is this W3 engine which also powered the 1909 Blériot XI, the first airplane to fly across the English Channel. The ''Feuling W3'' is a motorcycle engine that was built by an aftermarket parts company in the United States in the early 2000s. Like radial aircraft engines it has a master connecting rod and two slave rods connected to the pistons. W6 engines The Rumpler Tropfenwagen had a Siemens and Halske-built overhead valve W6 engine, with ... [...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 ...

Napier Cub
The Napier Cub was an unusual and very large experimental 16-cylinder 'X' pattern liquid-cooled aero engine built by the British engine company D. Napier & Son. The Cub was the only Napier 'X' engine design. First flown on 15 December 1922 in an Avro Aldershot biplane bomber aircraft, the only other application was in the Blackburn Cubaroo. Only six engines of this type were ordered and produced.Lumsden 2003, p.171. Design The four banks of four cylinders were arranged in a flattened 'X' when viewed from the front. The angle between the upper cylinders was 52.5 degrees, the lower cylinders 127.5 degrees, which gave an angle of 90 degrees between the outer cylinder banks. The cylinders consisted of separate individual steel forgings with welded steel water cooling jackets. The carburettor was situated below the propeller reduction gear at the front of the engine and fed the inlet valves through four inlet manifolds. The valve drive gear, magnetos and pumps were fitted to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isotta Fraschini Zeta R
Iseult (), alternatively Isolde () and other spellings, is the name of several characters in the legend of Tristan and Iseult. The most prominent is Iseult of Ireland, the wife of Mark of Cornwall and the lover of Tristan. Her mother, the queen of Ireland, is also named Iseult. The third is Iseult of the White Hands, the daughter of Hoel of Brittany and the sister of Kahedin. Name Her name is variably given as Iseult, Isolde, Yseult, Ysolt, Isode, Isoude, Iseut, Isaut (Old French), Iosóid (Irish), Esyllt (Welsh), Ysella (Cornish), Isolda (Portuguese, Spanish), Izolda (Serbian) and Isotta (Italian), among others. The oldest source, Béroul's 12th-century romance, spells her name as ''Yseut'' or ''Iseut''. The etymology is uncertain, with most sources linking it to the Old High German words ''īs'' ("ice") and ''hiltja'' ("battle"). Other writers derive it from a Brythonic *''Adsiltia'', "she who is gazed upon." Iseult of Ireland The Irish princess, Iseult of Ireland is the d ...

Rolls-Royce Exe
The Rolls-Royce Exe, or Boreas, was a 24-cylinder air-cooled X block sleeve valve aircraft engine intended primarily for the new Fairey Fleet Air Arm aircraft, particularly the Fairey Barracuda. The Exe was relatively powerful for its era, producing about . This is notable given the relatively small displacement, the Merlin requiring for approximately the same power level. The X-24 layout made this quite a compact engine. The Exe was named after the River Exe, although Rolls-Royce later transferred the use of river names to its gas turbine engines. Design and development The Exe was under development in 1939, having been started in the 1930s, along with the Peregrine and Vulture. Work on the Exe was suspended in August 1939, and stopped about August 1940. Ernest Hives, head of the Rolls-Royce aero engine division, wanted to stop work on the Exe, Peregrine, and Vulture to concentrate on the Merlin and Griffon engines. An enlarged version, the Rolls-Royce Pennine, was bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daimler-Benz DB 604
The Daimler-Benz DB 604 was an experimental German 24-cylinder aircraft engine, which did not progress beyond the initial engine testing phase and was ultimately abandoned in 1942. Design and development The DB 604 was unique among the DB 600 series of aircraft engines by having its 24 cylinders arranged in an X, with four inline rows of six cylinders. The DB 604 was also unique amongst the X-24 engines, in that it was not conceived as a further development of existing Daimler-Benz aircraft engines such as the DB 601, DB 603 or DB 605, which themselves had been twinned-up as two separate powerplants sharing a new common gear reduction case at their front ends, into the 1.5-tonne dry weight DB 601-based "coupled" DB 606 in February 1937, the same-weight figured DB 605-based DB 610 by June 1940, and just slightly earlier, in March 1940, the 1.8 tonne approximate weight replacement for the DB 606 and 610, the DB 603-based DB 613 "power system" of nearly 3,500 PS output.

Chelyabinsk Tractor Plant
Chelyabinsk Tractor Plant (russian: Челябинский тракторный завод, Chelyabinskiy traktornyy zavod, abbreviated , ) also known as CTZ-Uraltrak (''ЧТЗ-УРАЛТРАК'') is a tractor construction plant in the Russian city of Chelyabinsk. History The Chelyabinsk Tractor plant was a project of the first five-year plan. The plant was founded in 1933; the first product was a 60 hp tracked tractor C-60 (''Сталинец-60'', ''Stalinets-60'') fueled by petroleum ether (Benzine). In 1937 the factory produced its first diesel-powered vehicle C-65 (''Сталинец-65'', ''Stalinets-65''). By 1940 the plant had produced 100,000 tractors. During World War II seven other industrial entities (including most of Leningrad's Kirov Plant and 15,000 of its workers) were either wholly or partially relocated to Chelyabinsk, the resulting enterprise commonly known as "Танкоград" ('Tankograd', or 'Tank City'). The work force increased to 60,000 wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
