Airco DH.10 Amiens
The Airco DH.10 Amiens was a twin-engined heavy bomber designed and produced by the British aircraft manufacturer Airco. It performed the first nighttime air mail service in the world on 14-15 May 1919. The DH.10 was developed in the final years of the First World War in response to a requirement to equip the newly-formed Royal Air Force (RAF) with an expanded offensive bombing capability. It was based upon the earlier Airco DH.3 bomber, which had not been pursued largely due to disinterest in heavy bombers at that time. The first prototype performed its maiden flight on 4 March 1918; dissatisfaction with its performance led to the aircraft being redesigned with more powerful engines and a tractor configuration, which was received more favourably. Over 1,200 DH.10s were on order at one stage. Only a handful of DH.10s had been delivered to the RAF, and a single offensive mission conducted, before the Armistice of 11 November 1918 came into effect, ending the conflict. The dimin ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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".

Aeronautical Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

Siddeley-Deasy
The Siddeley-Deasy Motor Car Company Limited was a British automobile, aero engine and aircraft company based in Coventry in the early 20th century. It was central to the formation, by merger and buy-out, of the later Armstrong Siddeley Motor and Armstrong Whitworth Aircraft companies. History The Deasy Motor Car Manufacturing Company Limited was founded by Henry Hugh Peter Deasy in the factory that had previously been used to manufacture Iden cars. Deasy left in 1908 following disagreements with his Chief Engineer. In 1910 John Davenport Siddeley, 1st Baron Kenilworth, J D Siddeley took up the appointment of managing director having moved to Deasy in 1909 from managing Wolseley Motors, Wolseley.

Heaton Chapel
Heaton Chapel is an area in the northern part of Stockport, Greater Manchester, England. Within the boundaries of the historic county of Lancashire, it borders the Manchester districts of Levenshulme to the north, the Stockport districts of Heaton Moor to the west, Reddish and Heaton Norris to the east, and Heaton Mersey to the west and south. Heaton Chapel and its neighbouring areas are known collectively as the Four Heatons. History Before 1758, Heaton Chapel did not exist but was simply part of the Lancashire parish of Heaton Norris. The need for a chapel was identified in the Parliamentary Commission's ''Lancashire and Cheshire church surveys 1649–1655'', but it was a further hundred years before Mr A. Colier raised money by public subscription and Mr Sidebotham petitioned the bishop of Chester for a licence to worship in 1758; it was dedicated 28 October 1758. It is speculated that the need for the chapel was stimulated by the preaching of Charles Wesley who visite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subcontract
A subcontractor is a person or business which undertakes to perform part or all of the obligations of another's contract, and a subcontract is a contract which assigns part of an existing contract to a subcontractor. A general contractor, prime contractor or main contractor may hire subcontractors to perform specific tasks as part of an overall project to reduce costs or to mitigate project risks. In employing subcontractors, the general contractor hopes to receive the same or better service than the general contractor could have provided by itself, at lower overall risk. The European Union has recognised the need to make provision for sub-contracting in its rules on public procurement, as arrangements for sub-contracting can support the EU's drive to involve more small and medium-sized undertakings in the provision of goods and services for the public sector. Definition United States public acquisition regulations contain a number of distinct definitions of "subcontract" an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birmingham Small Arms Company
The Birmingham Small Arms Company Limited (BSA) was a major British industrial combine, a group of businesses manufacturing military and sporting firearms; bicycles; motorcycles; cars; buses and bodies; steel; iron castings; hand tool, hand, power tool, power, and machine tool, machine tools; coal cleaning and handling plants; sintered metals; and hard chrome process. After the Second World War, BSA did not manage its business well, and a government-organised rescue operation in 1973 led to a takeover of such operations as it still owned. Those few that survived this process disappeared into the ownership of other businesses.

Rolls-Royce Eagle
The Rolls-Royce Eagle was the first aircraft engine to be developed by Rolls-Royce Limited. Introduced in 1915 to meet British military requirements during World War I, it was used to power the Handley Page Type O bombers and a number of other military aircraft. The Eagle was the first engine to make a non-stop Transatlantic flight, trans-Atlantic crossing by aeroplane when two Eagles powered the converted Vickers Vimy bomber on the transatlantic flight of Alcock and Brown in June 1919. Background At the outbreak of World War I in August 1914, the Royal Aircraft Establishment, Royal Aircraft Factory asked Rolls-Royce to develop a new air-cooled engine. Despite initial reluctance, they agreed, on condition that it be cooled by water rather than by air, which was the company's area of expertise. Design and development Development of the new 20 litre engine was led by Henry Royce from his home in Kent. Based initially on the 7.4 litre 40/50 Rolls-Royce Silver Ghost engine, ...
