Rolls-Royce B Series Engine
The Rolls-Royce B range was a range of petrol engines first intended to be installed in a car but in 1943 developed into a range to power the British Army's wheeled vehicles.Rolls-Royce Motors Holdings Limited. ''The Times'', Monday, May 07, 1973; pg. 23; Issue 58775 The Alvis Saladin and Rolls-Royce Phantom IV were fitted with 8-cylinder versions. Overview Common features The B range of engines were all of the inline configuration, with crossflow inlet-over-exhaust cylinder heads and were naturally aspirated. They were heavily rationalized engines, which made use of as many common parts across the range as possible, for example, the 8 cylinder versions used 2 sets of the oil bath air filters, exhaust manifolds and points components of the 4 cylinder, while using the same carburettor as the 6. Pistons, rods, valves, springs, liners, etc. were common across the range, until the introduction of the overbored xx1 series, which still attempted to use as many common componen ...

Alvis Saladin
The FV601 Saladin is a six-wheeled armoured car developed by Crossley Motors and later manufactured by Alvis. Designed in 1954, it replaced the AEC Armoured Car in service with the British Army from 1958 onward. The vehicle weighed 11 tonnes, offered a top speed of 72 km/h, and had a crew of three. Saladins were noted for their excellent performance in desert conditions, and found favour with a number of Middle Eastern armies accordingly.''Middle East Economic Digest (1968)''. Collard, Elizabeth, Volume 12 pp. 131—173. They were armed with a 76 mm low-pressure rifled gun which fired the same ammunition as that mounted on the FV101 Scorpion. The Saladin also spawned an armoured personnel carrier counterpart, the Alvis Saracen. Despite the vehicle's age and dated design, it is still in use in a number of countries in secondary roles. History Development Following the end of the Second World War, the British Army issued a requirement for a new, 6×6 wheeled armoured v ...

Vanwall
Vanwall was a motor racing team and racing car constructor that was active in Formula One during the 1950s. Founded by Tony Vandervell, the Vanwall name was derived by combining the name of the team owner with that of his Thinwall bearings produced at the Vandervell Products factory at Acton, London. Originally entering modified Ferraris in non-championship races, Vanwall constructed their first cars to race in the 1954 Formula One season. The team achieved their first race win in the 1957 British Grand Prix, with Stirling Moss and Tony Brooks sharing a VW 5, earning the team the distinction of constructing the first British-built car to win a World Championship race. Vanwall won the inaugural Constructors' Championship in Formula One in , in the process allowing Moss and Brooks to finish second and third in the Drivers' Championship standings, winning three races each. Vandervell's failing health meant 1958 would be the last full season; the squad ran cars in a handful of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bentley Crewe
Bentley Crewe, also named the Pyms Lane site after the street it is located on; is the headquarters and design and manufacturing centre of Bentley Motors Limited on the outskirts of Crewe, Cheshire, England. The site covers an area of , of which is indoors. History Rolls-Royce Crewe In preparation for war, Rolls-Royce and the British Government searched for a location for a shadow factory to ensure production of aero-engines. Crewe, with its excellent road and rail links, as well as being located in the northwest away from the aerial bombing starting in mainland Europe, was a logical choice. Crewe also had extensive open farming land. Construction of the factory started on a 60-acre area on the potato fields of Merrill's Farm in July 1938, with the first Rolls-Royce Merlin aero-engine rolling off the production line five months later. 25,000 Merlin engines were produced and at its peak, in 1943 during World War II, the factory employed 10,000 people.

Rolls-Royce Meteor
The Rolls-Royce Meteor later renamed the Rover Meteor is a British tank engine that was developed during the Second World War. It was used in British tanks up to 1964. It was a result of co-operation between Leyland Motors and Rolls-Royce who between them in 1941 had suggested that a specialised de-rated version of the Merlin aero-engine would be highly suitable for use in armoured fighting vehicles. The Meteor was developed from the Merlin by W. A. Robotham and his chassis design and development division at Clan Foundry, Belper, as they were not involved in aero-engine work and his engineers were under-used. With the aid of engineers from Leyland, who were engaged in tank work, he considered RR's two V12s; the Kestrel, while having more power than the existing "Liberty" or Meadows engines, did not provide the desirable 20 bhp per ton (producing only 475 bhp on "pool" petrol) required, so the 1,030 bhp (770 kW) Merlin III was chosen. Also, the Merlin was being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belper
Belper is a town and civil parish in the local government district of Amber Valley in Derbyshire, England, located about north of Derby on the River Derwent. As well as Belper itself, the parish also includes the village of Milford and the hamlets of Bargate, Blackbrook and Makeney. As of the 2011 Census, the parish had a population of 21,823. Originally a centre for the nail-making industry since Medieval times, Belper expanded during the early Industrial Revolution to become one of the first mill towns with the establishment of several textile mills; as such, it forms part of the Derwent Valley Mills World Heritage Site. History At the time of the Norman occupation, Belper was part of the land centred on Duffield held by the family of Henry de Ferrers. The Domesday Book of 1086 records a manor of "Bradley" which is thought to have stood in an area of town now known as the Coppice. At that time it was probably within the Forest of East Derbyshire which covered the whole of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unified Fine Thread
The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. It has the same 60° profile as the ISO metric screw thread, but the characteristic dimensions of each UTS thread (outer diameter and pitch) were chosen as an inch fraction rather than a millimeter value. The UTS is currently controlled by ASME/ ANSI in the United States. Origins : ''See the "History of standardization" section of the screw thread article.'' Basic profile Each thread in the series is characterized by its major diameter ''D''maj and its pitch, ''P''. UTS threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The outermost and the innermost of the height ''H'' of the V- ...

Dry Sump
A dry-sump system is a method to manage the lubricating motor oil in four-stroke and large two-stroke piston driven internal combustion engines. The dry-sump system uses two or more oil pumps and a separate oil reservoir, as opposed to a conventional wet-sump system, which uses only the main sump (U.S.: oil pan) below the engine and a single pump. A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted. Dry-sumps are common on larger diesel engines such as those used in ships, as well as gasoline engines used in racing cars, aerobatic aircraft, high-performance personal watercraft and motorcycles. Dry sump lubrication may be chosen for these applications due to increased reliability, oil capacity, reduction of oil starvation under high g-loads and/or other technical or performance reasons. Dry sump systems may not be suitable for all applications due to increased cost, complexity, and/or bulk, am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octane Rating
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fue ...

British Standard Fine
British Standard Fine (BSF) is a screw thread form, as a fine-pitch alternative to British Standard Whitworth (BSW) thread. It was used for steel bolts and nuts on and in much of Britain's machinery, including cars, prior to adoption of Unified, and later Metric, standards. For highly stressed conditions, especially in motorcycles, a finer thread, British Standard Cycle (BSC), was used as well. BSF was developed by R. E. B. Crompton, and his assistant George Field. BSF threads use the 55 degree Whitworth thread form. It was introduced by the British Engineering Standards Association in 1908.Sidders 1969, p.16 The table provides BSF sizes, the threads per inch A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force.
