1956 Trans-Canada Air Lines Accident
Trans-Canada Air Lines Flight 304 was operated by a Vickers Viscount 700 aircraft owned by Trans-Canada Air Lines. On July 9, 1956, the No. 4 propeller of the aircraft tore loose from its engine over Flat Rock, Michigan in the United States, during a flight from Chicago, Illinois, to Toronto, Ontario, and Montreal, Quebec; one blade of the propeller sliced through the passenger section of the cabin, killing one passenger and injuring four passengers and one flight attendant. The aircraft diverted to Windsor, Ontario, in Canada, and the pilots carried out an emergency landing. The accident was the first to involve a Vickers Viscount aircraft in scheduled service, and was the first instance of a propeller loss on a turbo-prop aircraft. Aircraft background Trans-Canada Air Lines was the first North American airline to accept delivery of the Viscount. Unlike the piston engined aircraft (such as the Douglas DC-6 and the Lockheed Constellation) commonly flown by North American ...

Flat Rock, Michigan
Flat Rock is a city mostly in Wayne County of the U.S. state of Michigan. A very small portion of the city extends into Monroe County. At the 2010 census, the city population was 9,878. History Flat Rock began as a Wyandot settlement. It was later designated as a reservation for the Wyandot, and still functioned as such in 1830. The first European-American settlers in Flat Rock were Michael Vreeland and his five grown sons between 1811 and 1820. Michael had been captured by British Rangers during the Revolutionary War and released after American independence. The family purchased . The town was called the Village of Vreeland until 1838 when the Vreeland family sold off the majority of the land and relinquished control of the area. The Vreeland families built the first grain and lumber mill, having brought the grinding stones from New York. Descendants of Michael Vreeland still live in the town and attend Flat Rock public schools, being the seventh generation to reside in the t ...

Rolls-Royce Limited
Rolls-Royce was a British luxury car and later an aero-engine manufacturing business established in 1904 in Manchester by the partnership of Charles Rolls and Henry Royce. Building on Royce's good reputation established with his cranes, they quickly developed a reputation for superior engineering by manufacturing the "best car in the world". The business was incorporated as Rolls-Royce Limited in 1906, and a new factory in Derby was opened in 1908. The First World War brought the company into manufacturing aero-engines. Joint development of jet engines began in 1940, and they entered production. Rolls-Royce has built an enduring reputation for development and manufacture of engines for defence and civil aircraft. In the late 1960s, Rolls-Royce was adversely affected by the mismanaged development of its advanced RB211 jet engine and consequent cost over-runs, though it ultimately proved a great success. In 1971, the owners were obliged to liquidate their business. The useful p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airliner Accidents And Incidents Caused By Mechanical Failure
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Aeronautics Board
The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1938 and abolished in 1985, that regulated aviation services including scheduled passenger airline serviceStringer, David H."Non-Skeds: The Story of America’s Supplemental Airlines, Part 1: Industry in the United States,"'' AAHS Journal'', vol. 64, no.4 (Winter 2019) journal of the American Aviation Historical Society, excerpt online, retrieved April 8, 2020 and provided air accident investigation. The agency headquarters were in Washington, D.C. Functions The primary role of the CAB was to regulate scheduled commercial airline operations in the United States. The CAB strictly controlled all U.S. certificated airlines ("scheduled carriers") -- deciding which routes would be serviced by which airlines, and setting minimum limits on passenger fares (comparable to the Interstate Commerce Commission) -- effectively managing competition between airlines, and ensuring certain l ...

United States Government Role In Civil Aviation
The Air Commerce Act of 1926 created an Aeronautic Branch of the United States Department of Commerce. Its functions included testing and licensing of pilots, certification of aircraft and investigation of accidents. In 1934, the Aeronautics Branch was renamed the Bureau of Air Commerce, to reflect the growing importance of commercial flying. It was subsequently divided into two authorities: the Civil Aeronautics Administration (CAA), concerned with air traffic control, and the Civil Aeronautics Board (CAB), concerned with safety regulations and accident investigation. Under the Federal Aviation Act of 1958, the CAA's powers were transferred to a new independent body, the Federal Aviation Administration (FAA). In the same year, the National Aeronautics and Space Administration (NASA) was created after the Soviet Union’s launch of the first artificial satellite. The accident investigation powers of the CAB were transferred to the new National Transportation Safety Board in 1967, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windmill
A windmill is a structure that converts wind power into rotational energy using vanes called windmill sail, sails or blades, specifically to mill (grinding), mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the High Middle Ages, high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Culture of the Netherlands, Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bevel Gear
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears transfer the energy from linear to vertical power, making it very useful in machines widely used in mechanical settings. Introduction Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear ...
