Arthur Rubbra
Arthur Alexander Cecil Rubbra CBE (29 October 1903 – 24 November 1982) was an English engineer who designed many of Rolls-Royce's successful aero engines. He was "placed by many alongside Royce, Rowledge and Elliot as one of Rolls-Royce's greatest engineers...". Early life Rubbra was born in Northampton on 29 October 1903 to Edmund and Mary Rubbra who ran a watch and jewellery repair business. It is thought that the rare family surname was a form of "Ruborough", the Somerset village near Broomfield where his ancestors came from. His elder brother, Charles Edmund, was a distinguished composer. As a boy Rubbra was fascinated by steam engines and spent many hours at nearby Blisworth watching trains on the London–Crewe line. He was an accomplished artist and often sketched his favourite subjects. Rubbra attended Northampton Grammar School where he played rugby, and then Bristol University leaving in 1925 with a BSc. Career Rubbra's first job was with Armstrong Siddeley alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northampton
Northampton () is a market town and civil parish in the East Midlands of England, on the River Nene, north-west of London and south-east of Birmingham. The county town of Northamptonshire, Northampton is one of the largest towns in England; it had a population of 212,100 in its previous local authority in the United Kingdom Census 2011, 2011 census (225,100 as of 2018 estimates). In its urban area, which includes Boughton, Northamptonshire, Boughton and Moulton, Northamptonshire, Moulton, it had a population of 215,963 as of 2011.

In the Middle Ages, the town rose to national significance with the establishment of Northampton Castle, an occasional royal residence which regularly hosted the Parliament of England. Medieval Northampton had many churches, monasteries and the University of Northampton (thirteenth century), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Welland
The Rolls-Royce RB.23 Welland was Britain's first production jet engine.Janes 1989, p.268. It entered production in 1943 for the Gloster Meteor. The name Welland is taken from the River Welland, in keeping with the Rolls-Royce policy of naming early jet engines after rivers based on the idea of continuous flow, air through the engine and water in a river. The engine was originally developed by Frank Whittle's team at Power Jets and known as the W.2, Whittle's second design and the first intended for eventual production. Power Jets was working with Rover who referred to it as the W.2B/23. The relationship between the companies was strained due to Rover's inability to deliver working parts, and broke when Whittle learned that a team of Rover engineers led by Adrian Lombard and John Herriot had designed their own version, the W.2B/26. Fed up with Whittle, Rover handed the project to Rolls-Royce, where Stanley Hooker joined the team from Rolls' supercharger division. Hooker's exp ...

Rolls-Royce Eagle (1944)
The Rolls-Royce Eagle Mk XXII is a British 24-cylinder, sleeve valve, H-block aero engine of 46 litre (2,807 cubic inches) displacement. It was designed and built in the early-1940s by Rolls-Royce Limited and first ran in 1944. It was liquid-cooled, of flat H configuration with two crankshafts and was capable of 3,200 horsepower (2,387 kW) at 18 psi boost. Design and development The Rolls-Royce design team realised that producing a scaled-up version of their Griffon V-12 engine would lead to excessively large combustion chambers and problems with detonation.Rubbra 1990, p. 91. The team concluded that a larger number of small cylinders would be the answer and considered an X-24 design. This layout had previously caused unreliability with the Rolls-Royce Vulture due to the need to fasten four connecting rods in a complicated arrangement to a common big end bearing. The designers finally settled on an 'H' layout with two crankshafts and 'blade and fork' connecting rod attac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Griffon
The Rolls-Royce Griffon is a British 37-litre (2,240 cu in) capacity, 60-degree V-12, liquid-cooled aero engine designed and built by Rolls-Royce Limited. In keeping with company convention, the Griffon was named after a bird of prey, in this case the griffon vulture. Design work on the Griffon started in 1938 at the request of the Fleet Air Arm, for use in new aircraft designs such as the Fairey Firefly. In 1939 it was also decided that the engine could be adapted for use in the Spitfire. Development was stopped temporarily to concentrate efforts on the smaller Merlin and the 24-cylinder Vulture; the engine did not go into production until the early 1940s. The Griffon was the last in the line of V-12 aero engines to be produced by Rolls-Royce with production ceasing in 1955. Griffon engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight and power the last remaining airworthy Avro Shackleton. Design and development Origins Accor ...

Rolls-Royce Vulture
The Rolls-Royce Vulture was a British aero engine developed shortly before World War II that was designed and built by Rolls-Royce Limited. The Vulture used the unusual " X-24" configuration, whereby four cylinder blocks derived from the Rolls-Royce Peregrine were joined by a common crankshaft supported by a single crankcase. The engine was originally designed to produce around but problems with the Vulture design meant that the engines were derated to around 1,450 to 1,550 hp in service by limiting the maximum rpm. Although several new aircraft designs had been planned to use the Vulture, work on the engine's design ended in 1941 as Rolls-Royce concentrated on their more successful Merlin design. Another 24-cylinder engine, the Napier Sabre, proved more successful after a lengthy development period. Design and development The supercharged Rolls-Royce Kestrel and its derivative, the Rolls-Royce Peregrine, were fairly standard designs, with two cylinder banks arrange ...

Rolls-Royce Goshawk
The Rolls-Royce Goshawk was a development of the Rolls-Royce Kestrel that used evaporative or steam cooling. In line with Rolls-Royce convention of naming piston engines after birds of prey, it was named after the goshawk. The engine first ran in 1933 and provided 660 horsepower (490 kW). Only a few engines were built as the aircraft designs intended to use it were not adopted by the Royal Air Force. The Goshawk was used to power the Short Knuckleduster, the Supermarine Type 224 (a predecessor to the Supermarine Spitfire) and other prototype aircraft. Design and development The Goshawk was developed from the Kestrel IV prototype engine, to use evaporative (also known as "steam") cooling. Rather than keep the cooling liquid below its boiling point in the cooling system, the coolant was allowed to boil; the phase change from liquid to vapour takes more heat from the engine, so less weight of coolant is needed. However, the radiator had to be bulkier to accommodate coola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce R
The Rolls-Royce R is a British aero engine that was designed and built specifically for air racing purposes by Rolls-Royce Limited. Nineteen R engines were assembled in a limited production run between 1929 and 1931. Developed from the Rolls-Royce Buzzard, it was a 37-litre (2,240 cu in) capacity, supercharged V-12 capable of producing just under 2,800 horsepower (2,090 kW), and weighed 1,640 pounds (770 kg). Intensive factory testing revealed mechanical failures which were remedied by redesigning the components, greatly improving reliability. The R was used with great success in the Schneider Trophy seaplane competitions held in England in 1929 and 1931. Shortly after the 1931 competition, an R engine using a special fuel blend powered the winning Supermarine S.6B aircraft to a new airspeed record of over 400 miles per hour (640 km/h). Continuing through the 1930s, both new and used R engines were used to achieve various land and water sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rolls-Royce Personnel Codes
The Rolls-Royce company used an internal list of personnel shortcodes to identify its senior engineers and designers. These were usually based on a shortened form of the surname, later the initials. Such codes appeared on technical drawings and internal memos. The identities behind these codes represent an important part of the company history, especially during the period of intense development immediately before and during World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposin ....

Rolls-Royce Kestrel
The Kestrel or type F is a 21 litre (1,300 in³) 700 horsepower (520 kW) class V-12 aircraft engine from Rolls-Royce, their first cast-block engine and the pattern for most of their future piston-engine designs. Used during the interwar period, it provided excellent service on a number of British fighters and bombers of the era, such as the Hawker Fury and Hawker Hart family, and the Handley Page Heyford. The engine also sold to international air forces, and it was even used to power prototypes of German military aircraft types that were later used during the Battle of Britain. Several Kestrel engines remain airworthy today. Design and development Origin The Kestrel came about as a result of the excellent Curtiss D-12, one of the first truly successful cast-block engines. Earlier designs had used individually machined steel cylinders that were screwed onto a crankcase, whereas the cast-block design used a single block of aluminium that was machined to form cylinders.

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] |
