DC-4M
The Canadair North Star is a 1940s Canadian development, for Trans-Canada Air Lines (TCA), of the Douglas DC-4. Instead of radial piston engines used by the Douglas design, Canadair used Rolls-Royce Merlin V12 engines to achieve a higher cruising speed of compared with the of the standard DC-4. Requested by TCA in 1944, the prototype flew on 15 July 1946. The type was used by various airlines and by the Royal Canadian Air Force (RCAF). It proved to be reliable but noisy when in service through the 1950s and into the 1960s. Some examples continued to fly into the 1970s, converted to cargo aircraft. Design and development Canadair Aircraft Ltd. took over the Canadian Vickers Ltd. operations on 11 November 1944. Besides the existing Consolidated PBY Canso flying patrol boats in production, a development contract to produce a new variant of the Douglas DC-4 transport was still in effect. The new Canadair DC-4M powered by Rolls-Royce Merlin engines mounted in Rolls-Royce Universa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans-Canada Air Lines
Trans-Canada Air Lines (also known as TCA in English, and Trans-Canada in French) was a Canadian airline that operated as the country's flag carrier, with corporate headquarters in Montreal, Quebec. Its first president was Gordon Roy McGregor. Founded in 1937, it was renamed Air Canada in 1965. History With heavy involvement from C. D. Howe, a senior minister in the Mackenzie King cabinet, TCA was created by the Crown Corporation Canadian National Railway (CNR), and launched its first flight on 1 September 1937, on a flight between Vancouver and Seattle. An air-mail contract with Royal Mail Canada was one of the methods by which TCA was financed.http://www.thecanadianencyclopedia.com/articles/postal-system The creation of TCA was partly by CNR management who wanted to expand the company into the new field of passenger aviation, and was partly by government direction. Prior to TCA, no large national airline existed in Canada. With war looming, and other nations (primarily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canadair
Canadair Ltd. was a civil and military aircraft manufacturer in Canada. In 1986, its assets were acquired by Bombardier Aerospace, the aviation division of Canadian transport conglomerate Bombardier Inc. Canadair's origins lie in the establishment of a factory for Canadian Vickers in the Saint-Laurent borough of Montreal, at Cartierville Airport. It was created as a separate entity by the government of Canada on 11 November, 1944. Throughout much of its existence, it was a subsidiary of various other aircraft manufacturers prior to being nationalized by the Canadian government in 1976. For a decade, the company operated as a federally-owned Crown Corporation. In 1986, Canadair was privatized via its sale to Bombardier, after which it became a core element of the firm's aerospace division. The company's former principal manufacturing facility, ''Canadair Plant One'', remains intact to the present day, although Cartierville Airport itself has been closed and since undergone r ...

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 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'' 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".

North Star C-5
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney R-2800 Double Wasp
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of , and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade the engine, including water injection for takeoff in cargo and passenger planes and to give emergency power in combat. Design and development First run in 1937, near the time that the larger competing 18-cylinder Wright Duplex-Cyclone's development had been started in May of that year, the displacement R-2800 was first-flown by 1940, one year before the Duplex-Cyclone. The Double Wasp was more powerful than the world's only other modern 18-cylinder engine, the Gnome-Rhône 18L of . The Double Wasp was much smaller in displacement than either of the other 18-cylinder designs, and heat dissipation was a greate ...

The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east.
