Frakes Aviation
__NOTOC__ Frakes Aviation was founded by J. Fred Frakes in the late 1960s, and is located in Cleburne, Texas, United States. When founded, the company's main activity was converting radial engine powered airplanes to gas turbine engines. The company continued operations in this area of aviation into the mid-1980s, converting various airplanes. Frakes' most significant projects were the re-engineering of two Grumman products, the Ag-Cat and the Mallard, in both cases replacing the original radial piston engines with the Pratt & Whitney Canada PT6A. The company also converted a number of Aerospatiale Nord 262 airplanes for Mohawk Airlines (later used by Ransome Airlines, an Allegheny Commuter subsidiary airline) in the late 1970s. After long usage by Ransome Airlines at least two of these airplanes were exported to Australia where they were used for a short time before being retired. In the mid-1980s Frakes Aviation saw a need to diversify their business and ventured into afterm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleburne, Texas
Cleburne is a city in and the county seat of Johnson County, Texas, United States. As of the 2010 census, its population was 29,337. The city is named in honor of Patrick Cleburne, a Confederate general. Lake Pat Cleburne, the reservoir that provides water to the city and surrounding area, is also named after him. History Cleburne is Johnson County's third county seat (the first being Wardville, now under Lake Pat Cleburne). It was formerly known as Camp Henderson, a temporary Civil War outpost from which Johnson County soldiers would depart for war (most of them served under General Cleburne). The city was formally incorporated in 1871. Cleburne was near the earliest road in the county. The location featured water from West Buffalo Creek, making it a stop for cattlemen from the Chisholm Trail. In August 1886, the Texas Farmers' Alliance met at Lee's Academy and adopted a 17-point political resolution, commonly known as the Cleburne Demands, which was the first major docum ...

Airframe
The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost.Michael C. Y. Niu (1988). ''Airframe Structural Design''. Conmilit Press LTD. History Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs. In 1912 the Deperdussin Monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving . First World War Many early developments were spurred by military needs during World War I. Well known aircraft from that era include the Dutch designer Anth ...

Exhaust System
An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of: *Cylinder head and exhaust manifold *A turbocharger to increase engine power. *A catalytic converter to reduce air pollution. *A muffler (North America) / silencer (UK/India), to reduce noise. Design criteria An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with poisonous exhaust gases such as hydrocarbons, carbon monoxide and nitrogen oxides, if they are not properly vented to the outdoors. Also, the gases from most types of machines are very hot; the pipe must be heat-resistant, and it must not pass through or near anything that can burn or can b ...

Mohawk Airlines
Mohawk Airlines was a regional passenger airline operating in the Mid-Atlantic region of the United States, mainly in New York and Pennsylvania, from the mid-1940s until its acquisition by Allegheny Airlines in 1972. At its height, it employed over 2,200 personnel and pioneered several aspects of regional airline operations, including being the first airline in the United States to hire an African American flight attendant in 1958. The airline was based at Ithaca Municipal Airport near Ithaca, New York, until 1958, when it moved to Oneida County Airport in Whitestown, New York. History The airline was founded in 1945 as Robinson Airlines by aerial photographer C. S. Robinson as a unit of Robinson Aviation, completing its first passenger flight on 6 April. The operation was based out of Ithaca Municipal Airport near Ithaca, New York, flying single-engine, three-passenger Fairchild F-24s. After the end of World War II, the Fairchilds were supplemented with two Cessna T-50s, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 added i ...

Aérospatiale N 262
The Aérospatiale N 262 is a French twin-turboprop high-wing airliner built first by Nord Aviation (merged into Aérospatiale in 1970 in aviation, 1970). The aircraft was also known as the Nord 262. Design and development In 1957, the French aircraft manufacturer Max Holste began work on a twin-engined utility transport aircraft to replace the Douglas DC-3/C-47 Skytrain. The prototype, the Max Holste MH.250 Super Broussard, was powered by two Pratt & Whitney Wasp radial engines and first flew on 20 May 1959. A second prototype, the Nord 260, MH.260, powered by Turbomeca Bastan turboprop engines flew on 29 July 1960. In 1959, state-owned Nord Aviation (later merged with Sud Aviation and renamed Aérospatiale) signed an agreement with Max Holste to market and help produce the MH.260. Financial problems at Max Holste, however, led to Nord taking on the whole programme, with including further development of the aircraft, while Max Holste concentrated on the production of light airc ...

Pratt & Whitney Canada PT6A
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016.
