L-1649 Starliner
The Lockheed L-1649 Starliner was the last model of the Lockheed Constellation line of airliners. Powered by four Wright R-3350 TurboCompound engines, it was built at Lockheed's Burbank, California plant from 1956 to 1958. Design and development Development of the Starliner began when Lockheed designed the L-1449 in response to the Douglas DC-7C Seven Seas.Breffort, Dominique. Lockheed Constellation: from Excalibur to Starliner Civilian and Military Variants. Histoire and Collecions, 2006. p.112 to 117 Powered by four 5500 hp Pratt & Whitney PT2G-3 turboprop engines, the L-1449 would have cruised faster than the DC-7C with comparable range with of fuel in a new wing. Pratt & Whitney dropped the PT2 project in March 1955 due to expected unreliability, high specific fuel consumption and high operating costs, though the T34 military version of the engine powered the Douglas C-133 freighter, which was also plagued with unreliability. The L-1449 would have been about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Wikimedia project, 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 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".

Convair 880
The Convair 880 is an American narrow-body jet airliner produced by the Convair division of General Dynamics. It was designed to compete with the Boeing 707 and Douglas DC-8 by being smaller but faster, a niche that failed to create demand. When it was first introduced, some in aviation circles claimed that at , it was the fastest jet transport in the world. Only 65 Convair 880s were produced over the lifetime of the production run from 1959 to 1962, and General Dynamics eventually withdrew from the airliner market after considering the 880 project a failure. The Convair 990 Coronado was a stretched and faster variant of the 880. Development Convair began development of a medium-range commercial jet in April 1956, to compete with announced products from Boeing and Douglas. Initially the design was called the Skylark, but the name was later changed to the Golden Arrow, then Convair 600 and then finally the 880, both numbers referring to its top speed of 600 mph (970 ...

Robert N
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz'').

It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto.

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be ...

Lockheed L-1249 Super Constellation
The Lockheed L-1249 Super Constellation was a turboprop-powered version of the Lockheed Constellation aircraft family. Built in 1954 and 1955, the aircraft were used as prototypes for possible future military transport aircraft for both the United States Air Force and United States Navy. Both aircraft saw very short lives and the airframes were later used to build L-1049 Super Constellations. Design and development On 18 August 1950, the United States Navy signed a contract for 11 military transport versions of the Lockheed L-1049. The aircraft were to have been convertible troop/cargo transports, based on the model L-1049B (which was already being constructed as the PO-2W Warning Star). The R7O-1 would have also featured round portholes in place of the rectangular ones on Air Force C-121C Constellations. The aircraft entered evaluation service in the Navy's oldest test squadron, VX-1, based in Patuxent River, Maryland. In November 1951, an idea came about to build a turbine- ...

Hughes Tool Company
Hughes Tool Company was an American manufacturer of drill bits. Founded in 1908, it was merged into Baker Hughes Incorporated in 1987. History The company was established in December 1908 as Sharp-Hughes Tool Company when Howard R. Hughes Sr. patented a roller cutter bit that dramatically improved the rotary drilling process for oil drilling rigs. He partnered with longtime business associate Walter Benona Sharp to manufacture and market the bit. Following her husband's death in 1912, Sharp's widow Estelle Sharp sold her 50% share in the company to Howard Hughes Sr. in 1914. The company was renamed Hughes Tool Company on February 3, 1915. After Hughes Sr. died of a heart attack in 1924, the younger Howard inherited the majority interest in the company, and then convinced his relatives to sell their shares to him as well. Legally emancipated at the age of 18, Howard began using the profits from Hughes Tool to fund his other ventures. Toolco paid Hughes an annual salary of $50 ...
