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. Hooke ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Centrifugal Compressor
Centrifugal compressors, sometimes called impeller compressors or radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. They achieve pressure rise by adding energy to the continuous flow of fluid through the rotor/impeller. The following equation shows this specific energy input. A substantial portion of this energy is kinetic which is converted to increased potential energy/static pressure by slowing the flow through a diffuser. The static pressure rise in the impeller may roughly equal the rise in the diffuser. Equation-0.1 : H = \left( \left( R \right)_2 - \left( R \right)_1 \right) :where the control volume nomenclature (illustrated in Figure-0.4) is: ::* subscript, is the impeller inlet location, station1 ::* subscript, is the impeller discharge/exit location, station2 ::* is the energy input per unit mass, units=(LP/m) ::* is the impeller's rotation speed, units=(radians/t) ::* is the radius of specified location, units=(L) ::* is ve ...

John Grierson (pilot)
John Grierson (2 January 1909 – 21 May 1977) was an English long-distance flier, test pilot, author, and aviation administrator. Grierson started his flying lessons at Brooklands while still a schoolboy, graduated from RAF Cranwell in 1929, and flew out to India in 1930 in his own Gypsy Moth, named ''Rouge et Noir'', to join his RAF Squadron. In the same aircraft he established a record in 1931 with a 41½-day flight from Karachi, India to Lympne, England, and in 1932 flew 8,800 miles across the USSR to Samarkand. He had asked his friend Bernard Shaw to lobby the Soviet authorities to grant him passage. He met the Lindberghs in Reykjavík, Iceland in 1933. He was at that time attempting to fly solo to America in ''Rouge et Noir'', now fitted with floats, but overturned on take-off. His next effort was in a Fox Moth named ''Robert Bruce''. On his third try, Grierson successfully made the first London - Ottawa flight, at the same time making the first solo flight across ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernest Walter Hives, 1st Baron Hives (21 April 1886 – 24 April 1965), was the one-time head of the Rolls-Royce Aero Engine division and chairman of Rolls-Royce Ltd. Hives was born in Reading, Berkshire to John and Mary Hives, living at 31 Christchurch Road from at least 1891 to 1901. During the Second World War he was closely involved with the design of the Merlin engine as well as numerous later Rolls-Royce jet engines. He began his working life in a local garage.

Vickers Wellington
The Vickers Wellington was a British twin-engined, long-range medium bomber. It was designed during the mid-1930s at Brooklands in Weybridge, Surrey. Led by Vickers-Armstrongs' chief designer Rex Pierson; a key feature of the aircraft is its geodetic airframe fuselage structure, which was principally designed by Barnes Wallis. Development had been started in response to Air Ministry Specification B.9/32, issued in the middle of 1932, for a bomber for the Royal Air Force. This specification called for a twin-engined day bomber capable of delivering higher performance than any previous design. Other aircraft developed to the same specification include the Armstrong Whitworth Whitley and the Handley Page Hampden. During the development process, performance requirements such as for the tare weight changed substantially, and the engine used was not the one originally intended. The Wellington was used as a night bomber in the early years of the Second World War, performing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
