Harry Bickerton
Harry Bickerton (13 June 1921–23 March 1994) was a British engineer in the fields of aerospace engineering, engine design (aircraft), and bicycle design. Background In 1938, Bickerton left school to take up an apprenticeship at Rolls-Royce in Derby. He was transferred to Glasgow and was seconded to RAE Farnborough to work for Tilly Shilling, where he worked on water methanol injection and exhaust pipe tuning, among other things, for the Rolls-Royce 'Merlin' engine of the Spitfire fighter plane. After World War II, Bickerton, now a seasoned aircraft engineer, moved on to de Havilland where he was Chief Engineer and worked primarily on internal combustion engines (Gypsy Major) but also became involved in the investigation of the De Havilland Comet after a series of failures. He later re-designed the Gypsy Major engine for Britain's first helicopter (the Skeeter), and headed the development of extreme cold weather equipment for an Antarctic expedition by air. He also filed a pat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year Bachelor of Engineering, bachelor's degree in an engineering discipline, or in some jurisdictions, a Master of Engineering, master's degree in an engineering discipline plus ...

The Folder
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pro ...

Beatrice Shilling
Beatrice Shilling (8 March 1909 – 18 November 1990) was a British aeronautical engineer, motorcycle racing, motorcycle racer and Sports_car_racing#Post-war_revival, sports car racer. In 1949, Shilling was made an Officer of the Order of the British Empire. During the Second World War Shilling designed the Miss Shilling's orifice, RAE-Hobson injection carburettor which overcame the problem of the Rolls-Royce Merlin aeroplane engines losing power during negative-g manoeuvres. Shilling also worked on the Blue Streak missile, researched the effect of a wet runway upon braking, and helped design and build a bobsled for the Royal Air Force's Olympic team. As a motorcycle racer Shilling was one of only three women to receive the British Motorcycle Racing Club Gold Star for lapping the Brooklands circuit at over on a motorcycle. In sports car racing, she scored several podium finishes at the Goodwood Circuit Members' Meetings. Early life Shilling was born at Waterlooville, H ...

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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bickerton (bicycle)
The Bickerton, also called the Bickerton Portable, was a portable aluminium folding bicycle designed by Harry Bickerton and manufactured in the UK and Australia between 1971 and 1989. Bickerton, an accomplished engineer, suffered a three year driving ban in 1970 following a car crash, and invented the bike for himself, to be carried onto public transport or stored in the trunk of a car as small as an Austin Mini. Origins The Bickerton was a portable bicycle launched when folding bicycles tended to be step-through frames with a simple hinge, such as the folding variant of the Raleigh Twenty. The first Bickerton was made entirely of aluminium profiles, without any welds. The prototype was unique, lightweight (8.8kg, 18lb) and with a small folded size (76cm x 51cm x 23cm). For its day, it broke new ground in bicycle manufacturing. Production history Production started in 1972 in Codicote, Hertfordshire at around 300 units in the first two years. The weight was 9.1kg, strength ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folding Bicycle
A folding bicycle is a bicycle designed to fold into a compact form, facilitating transport and storage. When folded, the bikes can be more easily carried into buildings, on public transportation (facilitating mixed-mode commuting and bicycle commuting), and more easily stored in compact living quarters or aboard a car, boat or plane. Folding mechanisms vary, with each offering a distinct combination of folding speed, folding ease, compactness, ride, weight, durability, and price. Distinguished by the complexities of their folding mechanism, more demanding structural requirements, greater number of parts, and more specialized market appeal, folding bikes may be more expensive than comparable non-folding models. The choice of model, apart from cost considerations, is a matter of resolving the various practical requirements: a quick, easy fold, a compact folded size, or a faster but less compact model. There are also bicycles that provide similar advantages by separating into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alex Moulton
Alexander Eric Moulton (9 April 1920 – 9 December 2012) was an English engineer and inventor, specialising in suspension design. Early life and education Moulton's father, John Coney Moulton, was a naturalist working in the Far East.
