Rolls-Royce Derwent 5
The Rolls-Royce RB.37 Derwent is a 1940s British centrifugal compressor turbojet engine, the second Rolls-Royce jet engine to enter production. It was an improved version of the Rolls-Royce Welland, which itself was a renamed version of Frank Whittle's Power Jets W.2B. Rolls-Royce inherited the Derwent design from Rover when they took over their jet engine development in 1943. Design and development Rover When Rover was selected for production of Whittle's designs in 1941 they set up their main jet factory at Barnoldswick, staffed primarily by Power Jets personnel. Maurice Wilks was also aware of the potential of a more efficient straight-through design. This layout had already been used by Whittle in his drawings of the W2Y and W3X and was also being pursued by the de Havilland Company with the Halford H.1. Wilks set up a design office at Waterloo Mill, Clitheroe with Adrian Lombard leading the design of an engine with this configuration. The design was done in secret an ...

Welland
Welland is a city in the Regional Municipality of Niagara in Southern Ontario, Canada. As of 2021, it had a population of 55,750. The city is in the centre of Niagara and located within a half-hour driving distance to Niagara Falls, Niagara-on-the-Lake, St. Catharines, and Port Colborne. It has been traditionally known as the place ''where rails and water meet'', referring to the railways from Buffalo to Toronto and Southwestern Ontario, and the waterways of Welland Canal and Welland River, which played a great role in the city's development. The city has developed on both sides of the Welland River and Welland Canal, which connect Lake Erie and Lake Ontario. History The area was settled in 1788 by United Empire Loyalists who had been granted land by the Crown to compensate for losses due to property they left in the British Thirteen Colonies during and after the American Revolutionary War. Tensions continued between Great Britain and the newly independent United States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Minister Of Aircraft Production
The Minister of Aircraft Production was, from 1940 to 1945, the British government minister at the Ministry of Aircraft Production, one of the specialised supply ministries set up by the British Government during World War II. It was responsible for aircraft production for the British forces, primarily the Royal Air Force, but also the Fleet Air Arm. History During the war, British aircraft production quickly expanded to be the largest industry in the country, involving hundreds of private firms and employing nearly two million workers. The Ministry was set up to co-ordinate the activity of this industry to maximise aircraft production. There was a headquarters in London and twelve regions, each with a controller and resident Ministry representatives in most of the larger factories. The department was formed in May 1940 by the Prime Minister, Winston Churchill, to produce large numbers of aircraft to fight the Battle of Britain.

De Havilland Goblin
The de Havilland Goblin, originally designated as the Halford H-1, is an early turbojet engine designed by Frank Halford and built by de Havilland. The Goblin was the second British jet engine to fly, after Whittle's Power Jets W.1, and the first to pass a Type certificate, type test and receive a type certificate issued for an aircraft propulsion turbine. Although it was conceived in 1941 it remained unchanged in basic form for 13 years by which time it had evolved to the Mk. 35 export version. The Goblin was the primary engine of the de Havilland Vampire, and was to have been the engine for the F-80 Shooting Star (as the Allis-Chalmers J36) before that design switched engines due to production delays at Allis-Chalmers. The Goblin also powered the Saab 21R fighter, Fiat G.80 trainer and the de Havilland DH 108 "Swallow" experimental aircraft. The Goblin was later scaled up as the larger de Havilland Ghost, with the model numbers continuing from the last marks of the Goblin. ...
