Wright J-5
The Wright R-790 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by Wright Aeronautical Corporation, with a total displacement of about and around . These engines were the earliest members of the Wright Whirlwind engine family. Design and development The R-790 Whirlwind began as the Lawrance J-1, a nine-cylinder air-cooled radial developed in 1921 by the Lawrance Aero Engine Company for the U.S. Navy. The Navy was very enthusiastic about air-cooled engines, which it considered better suited for naval use than liquid-cooled ones.Wright J-5 "Whirlwind" (PDF), by Kimble D. McCutcheon, from the Aircraft Engine Historical Society Lawrance was a small company, though, and the Navy doubted it could produce enough engines for its needs. Despite urgings from the Nav ...

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".

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. In steam locomotives The term bore also applies to the cylinder of a steam locomotive or steam engine. Bore pitch Bore pitch is the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it in an internal combustion engine. It's also referred to as the "mean cylinder width", "bore spacing", "bore center distance" and "cylinder spacing". The bore pitch is always larger than the inside diameter of the cylinder (the bore and piston diameter) sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eisleben, Germany
Eisleben is a town in Saxony-Anhalt, Germany. It is famous as both the hometown of the influential theologian Martin Luther and the place where he died; hence, its official name is Lutherstadt Eisleben. First mentioned in the late 10th century, Eisleben is divided into the old town of Altstadt, and new town of Neustadt. Neustadt was created for Eisleben's miners in the 14th century. As of 2020, Eisleben had a population of 22,668. It lies on the Halle–Kassel railway. History Eisleben was first mentioned in 997 as a market called Islebia, and in 1180 as a town. The counts of Mansfeld governed the area until the 18th century. During the Protestant Reformation, Count Hoyer VI of Mansfeld-Vorderort (1477–1540) remained loyal to his Catholic faith, but the family's Mittelort and Hinterort branches sided with Martin Luther. The German Peasants' War devastated the area, about a century before the Thirty Years War. Count Albert VII of Mansfeld-Hinterort (1480–1560) signed the ...

Charles Levine
Charles Albert Levine (March 17, 1897 – December 6, 1991) was the first passenger aboard a transatlantic flight. He was ready to cross the Atlantic to claim the Orteig prize but a court battle over who was going to be in the airplane allowed Charles Lindbergh to leave first. Early life Levine was born on March 17, 1897, in North Adams, Massachusetts. He joined his father in selling scrap metal, later forming his own company buying and recycling World War I surplus brass shell casings. By 1927, at age 30, he was a millionaire. Columbia Air Liners and the record flights Levine and Giuseppe Mario Bellanca formed the Columbia Aircraft Company. Levine hired pilots Bert Acosta, Erroll Boyd, John Wycliff Isemann, Burr Leyson, and Roger Q. Williams at $200 a week to perform a series of publicity record attempts for the company. Levine entered the competition for the Orteig prize for the first person to complete a nonstop flight from New York to Paris. His Bellanca designed prototy ...

Bellanca WB-2
The Wright-Bellanca WB-2, was a high wing monoplane aircraft designed by Giuseppe Mario Bellanca, initially for Wright Aeronautical then later Columbia Aircraft Corp. Based on its all-wood forerunner, the Wright-Bellanca WB-1, only one was produced, variously named ''Columbia'', ''Miss Columbia'', and later ''Maple Leaf''. The WB was the second in a series of designs by Bellanca, following his prior fabric-covered all-wood CE biplane. Development In 1925, Clarence Duncan Chamberlin was friends with, and worked as chief test pilot for, the aircraft designer Giuseppe Mario Bellanca. A flight instructor in World War I, Chamberlin was an early customer of Bellanca designs, purchasing the only Bellanca CE, built when he was working for the Maryland Pressed Steel Company. Through Chamberlin, Bellanca secured a position as a consultant for the Wright Aeronautical company to produce a 5–6 passenger aircraft to demonstrate their new Wright Whirlwind J-4 engine.

Clarence Chamberlin
Clarence Duncan Chamberlin (November 11, 1893 – October 31, 1976) was an American pioneer of aviation, being the second man to pilot a fixed-wing aircraft across the Atlantic Ocean, from New York to the European mainland, while carrying the first transatlantic passenger. Early years Clarence Duncan Chamberlin was born on November 11, 1893, in the small town of Denison, Iowa, to Elzie Clarence and Jessie Duncan Chamberlin. Elzie, or "EC" as he was known around Denison, was the local jeweler and the owner of the first automobile in Denison. This automobile was notorious throughout Crawford County for the racket it emitted while in operation. Indeed, maintenance of the vehicle was a near constant endeavor; however, it was in maintaining the family automobile that Chamberlin first developed an interest in all things mechanical. Additionally, he found great delight in using his mechanical skills to repair the clocks and watches that would be brought into his father's jewelry shop on a ...
