Adrian Lombard
Adrian Albert "Lom" Lombard, CBE (19 January 1915 – 13 July 1967) was an English aeronautical engineer. Despite having no formal training in aerodynamics, he became one of the world's foremost designers of jet engines. He was involved with the Rolls-Royce company in a variety of roles for almost 30 years. Biography Adrian Lombard was born in the city of Coventry, Warwickshire, on 19 January 1915. He was the second of three sons of Arthur, a toolmaker, and Louisa. Lombard was taught at the John Gulson Central Advanced School, and later attended evening classes at the Coventry Technical College. After leaving school at the age of 15, he began training in the drawing office of the Rover Company. Early career After spending five years with Rover, Lombard took a job with Morris Motors Limited where he was put in charge of engine stress calculations and worked as a motor car engineer. However, he returned to Rover in 1936 and within four years was part of Maurice Wilks' desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boeing 707
The Boeing 707 is an American, long-range, narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype first flown in 1954, the initial first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 was a swept wing, quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models. Although it was not the first commercial jetliner in service, the 707 was the first to be widespread and is often credited with beginning the Jet Age. It dominated passenger air transport in the 1960s, and remained common through the 1970s, on domestic, transcontinental, and transatlantic flights, as well as cargo and military applications. It established Boeing as a dominant airliner manufacturer with its 7x7 series. The initial, was powered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers VC10
The Vickers VC10 is a mid-sized, narrow-body long-range British jet airliner designed and built by Vickers-Armstrongs (Aircraft) Ltd and first flown at Brooklands, Surrey, in 1962. The airliner was designed to operate on long-distance routes from the shorter runways of the era and commanded excellent hot and high performance for operations from African airports. The performance of the VC10 was such that it achieved the fastest crossing of the Atlantic by a subsonic jet airliner of 5 hours and 1 minute, a record that was held for 41 years, until February 2020 when a British Airways Boeing 747 broke the record at 4 hours 56 minutes due to Storm Ciara. Only the supersonic Concorde was faster. The VC10 is often compared to the larger Soviet Ilyushin Il-62, the two types being the only airliners to use a rear-engined quad layout. The smaller business jet Lockheed JetStar also has this engine arrangement. Although only a relatively small number of VC10s were built, they provide ...

Rolls-Royce Conway
The Rolls-Royce RB.80 Conway was the first turbofan engine to enter service. Development started at Rolls-Royce in the 1940s, but the design was used only briefly, in the late 1950s and early 1960s, before other turbofan designs replaced it. However, the Conway engine was used in versions of the Handley Page Victor, Vickers VC10, Boeing 707-420 and Douglas DC-8-40. The name "Conway" is the English spelling of the River Conwy, in Wales, in keeping with Rolls' use of river names for gas turbine engines. Development Background Alan Arnold Griffith had proposed a number of different bypass or turbofan engine designs as early as the 1930s while he and Hayne Constant were trying to get their axial-flow jet engines working at the Royal Aircraft Establishment. However, simpler turbojet designs were prioritized during World War II for their use in military applications. Priorities changed dramatically at the end of the war and in 1946 Rolls-Royce agreed that existing engines like the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Transatlantic Flight
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, Central America, or South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloons and other aircraft. Early aircraft engines did not have the reliability nor the power to lift the required fuel to make a transatlantic flight. There were difficulties navigating over the featureless expanse of water for thousands of miles, and the weather, especially in the North Atlantic, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commercial, military, diplomatic, and other purposes. History The idea of transatlantic flight came about with the advent of the hot air balloon. The balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough lift to use the winds that would later be ...

De Havilland Comet
The de Havilland DH.106 Comet was the world's first commercial jet airliner. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. Within a year of entering airline service, problems started to emerge, three Comets being lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time; the other was due to overstressing of the airframe during flight through severe weather. The Comet was withdrawn from service and extensively tested. Design and cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairey Delta
The Fairey Delta 2 or FD2 (internal designation Type V within Fairey) is a British supersonic research aircraft that was produced by the Fairey Aviation Company in response to a specification from the Ministry of Supply for a specialised aircraft for conducting investigations into flight and control at transonic and supersonic speeds. Features included a delta wing and a drooped nose. On 6 October 1954, the Delta 2 made its maiden flight, flown by Fairey test pilot Peter Twiss; two aircraft would be produced. The Delta 2 was the final aircraft to be produced by Fairey as an independent manufacturer. The Fairey Delta 2 was the first jet aircraft to exceed in level flight. On 10 March 1956, it set a new world speed record of , exceeding the previous official record by . The Delta 2 held the absolute World Air Speed Record for over a year. It continued to be used for flight testing, and was allocated to the Royal Aircraft Establishment (RAE) in 1958. A testbed aircraft was requi ...

Rolls-Royce Avon
The Rolls-Royce Avon was the first axial flow jet engine designed and produced by Rolls-Royce. Introduced in 1950, the engine went on to become one of their most successful post-World War II engine designs. It was used in a wide variety of aircraft, both military and civilian, as well as versions for stationary and maritime power. An English Electric Canberra powered by two Avons made the first un-refuelled non-stop transatlantic flight by a jet, and a BOAC de Havilland Comet 4 powered by four Avons made the first scheduled transatlantic crossing by a jet airliner. Production of the Avon aero engine version ended after 24 years in 1974.Gunston 1989, p. 149. Production of the Avon-derived industrial version, currently produced by Siemens, continues to this day. The current version of the Avon, the Avon 200, is an industrial gas generator that is rated at . As of 2011, 1,200 Industrial Avons have been sold, and the type has established a 60,000,000 hour record for its class. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derby
Derby ( ) is a city and unitary authority area in Derbyshire, England. It lies on the banks of the River Derwent in the south of Derbyshire, which is in the East Midlands Region. It was traditionally the county town of Derbyshire. Derby gained city status in 1977, the population size has increased by 5.1%, from around 248,800 in 2011 to 261,400 in 2021. Derby was settled by Romans, who established the town of Derventio, later captured by the Anglo-Saxons, and later still by the Vikings, who made their town of one of the Five Boroughs of the Danelaw. Initially a market town, Derby grew rapidly in the industrial era. Home to Lombe's Mill, an early British factory, Derby has a claim to be one of the birthplaces of the Industrial Revolution. It contains the southern part of the Derwent Valley Mills World Heritage Site. With the arrival of the railways in the 19th century, Derby became a centre of the British rail industry. Derby is a centre for advanced transport manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloster Meteor
The Gloster Meteor was the first British jet fighter and the Allies of World War II, Allies' only jet aircraft to engage in combat operations during the Second World War. The Meteor's development was heavily reliant on its ground-breaking turbojet engines, pioneered by Frank Whittle and his company, Power Jets, Power Jets Ltd. Development of the aircraft began in 1940, although work on the engines had been under way since 1936. The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF. The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter. Gloster's 1946 civil Meteor F.4 demonstrator ''G-AIDC'' was the first Aircraft registration, civilian-registered jet aircraft in the world. Several major variants of the Meteor incorporated technological advances during the 1940s and 1950s. Thousands of Meteors were built to fly with the RAF and other air forces and remained in use for several decade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
