Piper Aircraft
Piper Aircraft, Inc. is a manufacturer of general aviation aircraft, located at the Vero Beach Regional Airport in Vero Beach, Florida, United States and owned since 2009 by the Government of Brunei. Throughout much of the mid-to-late 20th century, it was considered to be one of the "Big Three" in the field of general aviation manufacturing, along with Beechcraft and Cessna.Pattillo (1998), p. 83 Between its founding in 1927 and the end of 2009, the company produced 144,000 aircraft in 160 certified models, of which 90,000 are still flying. History The company was founded as the Taylor Brothers Aircraft Manufacturing Company in September 1927 by brothers Clarence G. Taylor and Gordon A. Taylor in Rochester, New York. The company was renamed Taylor Brothers Aircraft Corporation in April 1928, shortly before Gordon Taylor died in an aircraft accident on April 24, 1928. The company was enticed to move to Bradford, Pennsylvania, with the promise of a larger facility and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piper Seminole
The Piper PA-44 Seminole is an American twin-engined light aircraft manufactured by Piper Aircraft. The PA-44 is a development of the Piper Cherokee single-engined aircraft and is primarily used for multi-engined flight training.Montgomery, MR & Gerald Foster: ''A Field Guide to Airplanes, Second Edition'', page 92. Houghton Mifflin Company, 1992. The Seminole was built in 1979–1982, in 1989–1990, and has been in production since 1995. Design and development The first production Seminoles are equipped with two 180 hp (135 kW) Lycoming O-360-E1A6D engines. The right-hand engine is a Lycoming LO-360-E1A6D variant, which turns in the opposite direction to the left-hand engine. This feature eliminates the critical engine and makes the aircraft more controllable in the event that an engine needs to be shut down or fails. The first prototype Seminole made its maiden flight in May 1976 and the type was publicly announced on February 21, 1978. The Seminole was fir ...

Flat-four
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycoming IO-320
The Lycoming O-320 is a large family of naturally aspirated, air-cooled, four-cylinder, direct-drive engines produced by Lycoming Engines. They are commonly used on light aircraft such as the Cessna 172 and Piper Cherokee. Different variants are rated for 150 or 160 horsepower (112 or 119 kilowatts). As implied by the engine's name, its cylinders are arranged in horizontally opposed configuration and a displacement of 320 cubic inches (5.24 L). Design and development The O-320 family of engines includes the carbureted O-320, the fuel-injected IO-320, the inverted mount, fuel-injected AIO-320 and the aerobatic, fuel-injected AEIO-320 series. The LIO-320 is a "left-handed" version with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine. The first O-320 (with no suffix) was FAA certified on 28 July 1953 to CAR 13 effective 5 March 1952; this same engine was later re-designated, without change, as the O-320- ...

Federal Aviation Administration
The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrounding international waters. Its powers include air traffic management, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. Created in , the FAA replaced the former Civil Aeronautics Administration (CAA) and later became an agency within the U.S. Department of Transportation. Major functions The FAA's roles include: *Regulating U.S. commercial space transportation *Regulating air navigation facilities' geometric and flight inspection standards *Encouraging and developing civil aeronautics, including new aviation technology *Issuing, suspending, or revoking ...

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Engine
The critical engine of a multi-engine fixed-wing aircraft is the engine that, in the event of failure, would most adversely affect the performance or handling abilities of an aircraft. On propeller aircraft, there is a difference in the remaining yawing moments after failure of the left or the right (outboard) engine when all propellers rotate in the same direction due to the P-factor. On turbojet and turbofan twin-engine aircraft, there usually is no difference between the yawing moments after failure of a left or right engine in no-wind condition. Description When one of the engines on a typical multi-engine aircraft becomes inoperative, a thrust imbalance exists between the operative and inoperative sides of the aircraft. This thrust imbalance causes several negative effects in addition to the loss of one engine's thrust. The tail-design engineer is responsible for determining the size of vertical stabilizer that will comply with the regulatory requirements for the control an ...

Time Between Overhaul
Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul. On rotorcraft, many components have recommended or mandatory TBOs, including main rotor blades, tail rotor blades and gearboxes. For engines, the time between overhauls is generally a function of the complexity of the engine and how it is used. Piston-based engines are much more complex than turbine-powered engines, and generally have TBOs on the order of 1,200 to 2,000 hours of running time. They tend toward the lower number if they are new designs, or include boosting options such as a turbocharger. In comparison, jet engines and turboprop A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel ... ...

Prince William Of Gloucester
Prince William of Gloucester (William Henry Andrew Frederick; 18 December 1941 – 28 August 1972) was a grandson of King George V and paternal cousin of Queen Elizabeth II. At birth he was fourth in line to the throne; he was ninth in line at the time of his death. A Cambridge and Stanford graduate, he joined the Foreign and Commonwealth Office serving in Lagos and Tokyo, before returning to take over royal duties. He led an active life, flying Piper aircraft, trekking through the Sahara, and hot air ballooning. He was the most recent descendant of George III to be diagnosed with porphyria, probably hereditary, which is conjectured to be the illness that caused George III's mental breakdown. Prince William died in 1972, aged 30, in an air crash while piloting his plane in a competition. Early life Prince William was born at Hadley Common, Hertfordshire. His father was Prince Henry, Duke of Gloucester, the third son of King George V and Queen Mary. His mother was Alic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
