Wright J-6-5 Whirlwind
The Wright R-540 Whirlwind was a series of five-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of 540 in³ (8.85 L) and power ratings of around 165-175 hp (123-130 kW). They were the smallest members of the Wright Whirlwind engine family. Design and development Wright introduced the J-6 Whirlwind family in 1928 to replace the nine-cylinder R-790 series. The J-6 family included varieties with five, seven, and nine cylinders. The five-cylinder version was originally known as the J-6 Whirlwind Five, or J-6-5 for short. The U.S. government designated it as the R-540; Wright later adopted this and dropped the J-6 nomenclature. Like all the members of the J-6 Whirlwind family, the R-540 had larger cylinders than the R-790. The piston stroke of 5.5 in (14.0 cm) was unchanged, but the cylinder bore was expanded to 5.0 in (12.7 cm) from the R-790's bore ...

Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emsco B-7
The Emsco B-4 Cirrus was a mid-wing, two-seat trainer built in the US in the late 1920s. Six were built and three variants with more powerful engines flown. Design The two-seat B-4 trainer was a mid-wing monoplane with wings of rectangular plan out to blunted tips. Structurally, the largely wooden wings were based on pairs of box spars and spruce and plywood ribs, with duralumin sheet stiffening the leading edges. The rest of the wing was fabric covered. They were wire-braced from above and below with streamlined wires from pylons within the fuselage to the spars. Its Frise ailerons were inset. The B-4's fuselage was based on a chrome-molybdenum steel frame. It had a American Cirrus III four-cylinder, upright inline engine in the nose with an aluminium firewall and tanks in the wing roots. The two tandem cockpits, fitted with dual controls, were over the wing. The view from the forward cockpit, placed around quarter- chord, was good and the instructor's view from ...

Parks P-2
The Parks P-2, powered by a 150 hp Axelson-Floco B engine, was a biplane designed and built at the Parks Air College in the United States circa 1929. A change in engine type to the Wright J-6 The Wright Whirlwind was a family of air-cooled radial aircraft engines built by Wright Aeronautical (originally an independent company, later a division of Curtiss-Wright). The family began with nine-cylinder engines, and later expanded to inc ... resulted in the Parks P-2A, which was ultimately marketed as the Ryan Speedster after rights were bought by the Ryan company. The Parks P-2A became the "hero" of books by author Richard Bach who also owned an example. The college quickly left the manufacturing business, selling the P-2A rights to Ryan as the Ryan Speedster, and later the Hammond 100.

Dublin
Dublin (; , or ) is the capital and largest city of Ireland. On a bay at the mouth of the River Liffey, it is in the province of Leinster, bordered on the south by the Dublin Mountains, a part of the Wicklow Mountains range. At the 2016 census it had a population of 1,173,179, while the preliminary results of the 2022 census recorded that County Dublin as a whole had a population of 1,450,701, and that the population of the Greater Dublin Area was over 2 million, or roughly 40% of the Republic of Ireland's total population. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixth largest in Western Europe after the Acts of Union in 1800. Following independence in 1922, Dubli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Douglas Corrigan
Douglas Corrigan (January 22, 1907 – December 9, 1995) was an American aviator, nicknamed "Wrong Way" in 1938. After a transcontinental flight in July from Long Beach, California, to New York City, he then flew from Floyd Bennett Field in Brooklyn to Ireland, though his flight plan was filed to return to Long Beach. Corrigan claimed his unauthorized transatlantic flight was due to a navigational error, caused by heavy cloud cover that obscured landmarks and low-light conditions, causing him to misread his compass. However, he was a skilled aircraft mechanic (he helped construct Charles Lindbergh's '' Spirit of St. Louis'') and had made several modifications to his own plane, preparing it for his transatlantic flight. He had been denied permission to make a nonstop flight from New York to Ireland, and his "navigational error" was seen as deliberate. Nevertheless, he never publicly admitted to having flown to Ireland intentionally. Early life ''Clyde Groce Corrigan'' was named fo ...

Meridian, Mississippi
Meridian is the seventh largest city in the U.S. state of Mississippi, with a population of 41,148 at the 2010 census and an estimated population in 2018 of 36,347. It is the county seat of Lauderdale County and the principal city of the Meridian, Mississippi Micropolitan Statistical Area. Along major highways, the city is east of Jackson, Mississippi; southwest of Birmingham, Alabama; northeast of New Orleans, Louisiana; and southeast of Memphis, Tennessee. Established in 1860, at the junction of the Mobile and Ohio Railroad and Southern Railway of Mississippi, Meridian built an economy based on the railways and goods transported on them, and it became a strategic trading center. During the American Civil War, General William Tecumseh Sherman burned much of the city to the ground in the Battle of Meridian (February 1864). Rebuilt after the war, the city entered a "Golden Age". It became the largest city in Mississippi between 1890 and 1930, and a leading center for manu ...

The Flying Keys
Fred and Al Key were brothers who performed barnstorming events and other activities during the early 20th century. They are best known for their flight endurance record, which they cemented at twenty-seven days. They also invented a valve for aerial refueling that became the industry standard for the United States military. Early history and record attempt Brothers Fred and Al Key became interested in aviation after World War I. They started doing some barnstorming in the 1920s and continued their interest as the managers of the Meridian Municipal Airport, in Meridian, Mississippi. With the onset of the Great Depression, the city of Meridian began doing whatever it could to save money. The airport was considered unnecessary, given the economic conditions, and was slated to be closed. The Key brothers had no desire to see this happen, so they came up with a plan to draw attention to Meridian and its airport by breaking the standing flight endurance record of 23 days. At that ...
