CV880
The Convair 880 is a retired American Narrow-body aircraft, narrow-body jet airliner produced by the Convair division of General Dynamics. It was designed to compete with the Boeing 707 and Douglas DC-8 by being smaller but faster, a niche that failed to create demand. When it was first introduced, some in aviation circles claimed that at , it was the fastest jet transport in the world. Only 65 Convair 880s were produced over the lifetime of the production run from 1959 to 1962, and General Dynamics eventually withdrew from the airliner market after considering the 880 project a failure. The Convair 990 Coronado was a stretched and faster variant of the 880. Development Convair began development of a medium-range commercial jet in April 1956, to compete with announced products from Boeing and Douglas Aircraft Company, Douglas. Initially the design was called the Skylark, but the name was later changed to the Golden Arrow, then Convair 600 and then finally the 880, both numbers r ...

Douglas DC-8
The Douglas DC-8 (sometimes McDonnell Douglas DC-8) is an early long-range Narrow-body aircraft, narrow-body jetliner designed and produced by the American Douglas Aircraft Company. Work began in 1952 towards the United States Air Force's (USAF) requirement for a jet-powered aerial refueling, aerial refueling tanker. After losing the USAF's tanker competition to the rival Boeing KC-135 Stratotanker in May 1954, Douglas announced in June 1955 its derived jetliner project marketed to civil operators. In October 1955, Pan American World Airways, Pan Am made the first order along with the competing Boeing 707, and many other airlines soon followed. The first DC-8 was rolled out in Long Beach Airport on April 9, 1958, and flew for the first time on May 30. Following Federal Aviation Administration (FAA) certification in August 1959, the DC-8 entered service with Delta Air Lines on September 18.

Narrow-body Aircraft
A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than , allowing at least seven-abreast seating and often more travel classes. Market Historically, beginning in the late 1960s and continuing through the 1990s, twin engine narrow-body aircraft, such as the Boeing 737 Classic, McDonnell-Douglas MD-80 and Airbus A320 were primarily employed in short to medium-haul markets requiring neither the range nor the passenger-carrying capacity of that period's wide-body aircraft. The re-engined Boeing 737 MAX and Airbus A320neo jets offer 500 miles more range, allowing them to operate the 3,000 miles transatlantic flights between the eastern U.S. and Western Europe, previously dominated by wide-body aircraft.

Viasa
Venezolana Internacional de Aviación Sociedad Anónima (), or VIASA for short, was the Venezuelan flag carrier airline between 1960 and 1997. It was headquartered in the Torre Viasa in Caracas. Launched in , it was nationalised in 1975 due to financial problems, and re-privatised in 1991, with the major stake going to Iberia. The company ceased operations in , and went into liquidation. History Early years Viasa was envisioned by the government of Venezuela in 1959 to create a new company that could serve as the country's flag carrier and run without government intervention. It was set up in 1960 when the international routes operated by Línea Aeropostal Venezolana (LAV) and Avensa were merged and taken over by the newly created carrier. The government contributed with 55% of the capital, while private investors – among which were LAV and Avensa, the latter owned by Grupo Boulton and Pan American World Airways—contributed with the remainder.

Northeast Airlines
Northeast Airlines was an American trunk carrier, a scheduled airline based in Boston, Massachusetts, originally founded as Boston-Maine Airways that chiefly operated in the northeastern United States, and later to Canada, Florida, the Bahamas, Bermuda and other cities. It was notably small and unprofitable relative to other trunk carriers, being less than half the size, by revenue, than the next biggest trunk in 1971. Northeast was acquired by and merged into Delta Air Lines in August 1972. From 1975 onward, Air New England was essentially a reincarnation of many of the New England routes of Northeast Airlines, complete with the aircraft Northeast used to fly those routes and Northeast's IATA code. History Early days and certification The airline began as Boston-Maine Airways, founded as a Pan Am contract carrier on July 20, 1931, by the Boston and Maine Railroad and Maine Central Railroad, flying from Boston to Bangor via Portland. It flew only sporadically until August 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convair 990
The Convair 990 Coronado is a retired American narrow-body four-engined jet airliner produced between 1961 and 1963 by the Convair division of American company General Dynamics. It was a stretched version of its earlier Convair 880 produced in response to a request from American Airlines: the 990 was lengthened by , which increased the number of passengers from between 88 and 110 in the 880 to between 96 and 121. This was still fewer passengers than the contemporary Boeing 707 (110 to 189) or Douglas DC-8 (105 to 173), although the 990 was faster than either in cruise. Design and development American Airlines asked Convair to design an aircraft for coast-to-coast flights, able to fly nonstop from New York City to Los Angeles against the wind. They wanted a larger passenger capacity than the Convair 880, which was the smallest of the first-generation U.S. jet airliners. The design was known as the Convair 600 and was redesignated the Convair 990 in the month of its first flight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krueger Flap
Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Unlike Leading-edge slat, slats or leading-edge droop flap, droop flaps, the main wing upper surface and its leading edge is not changed. Instead, a portion of the lower wing is rotated out in front of the main wing leading edge. The Boeing 707 and Boeing 747 used Krueger flaps on the wing leading edge. Several modern aircraft use Krueger flaps between the fuselage and closest engine, but use leading-edge slat, slats outboard of the closest engine. The Boeing 727 also used a mix of inboard Krueger flaps and outboard slats, although it had no engine between them. Operation While the aerodynamic effect of Krueger flaps may be similar to that of Leading edge slats, slats or Leading edge slot, slots (in those cases where there is a gap or slot between the flap trailing edge and wing leading edge), they are deployed differently. Krueger flaps, hinged at their forem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney JT3C
The Pratt & Whitney J57 (company designation: JT3C) is an axial-flow compressor, axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s. The J57 (first run January 1950) was the first 10,000 pound-force, lbf (45 kN) thrust class engine in the United States. It is a two spool engine. The J57/JT3C was developed into the Pratt & Whitney J52, J52 turbojet, the Pratt & Whitney J75, J75/JT4A turbojet, the Pratt & Whitney JT3D, JT3D/TF33 turbofan, and the Pratt & Whitney XT57, XT57 turboprop (of which only one was built). The J57 and JT3C saw extensive use on fighter jets, jetliners, and bombers for many decades. Design and development The J57 was a development of the Pratt & Whitney XT45 (PT4) turboprop engine that was originally intended for the Boeing B-52 Stratofortress, Boeing XB-52. As the B-52 power requirements grew, the design evolved into a turbojet, the JT3. Pratt & Whitney designed the J57 to have a relatively high overall pressure ratio to help ...

Thrust Specific Fuel Consumption
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence ''thrust-specific''. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit fuel consumed. TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel measure, since it is independent of temperature. Specific fuel consumption of air-breathing jet engines at their maximum efficiency is more or less proportional to exhaust speed. The fuel consumption ''per mile'' or ''per kilometre'' is a more appropriate comparison for aircraft that travel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 720
The Boeing 720 is a retired American narrow-body airliner produced by Boeing Commercial Airplanes. Announced in July 1957 as a 707 derivative for shorter flights from shorter runways, the 720 first flew on November 23, 1959. Its type certificate was issued on June 30, 1960, and it entered service with United Airlines on July 5, 1960. A total of 154 Boeing 720s and 720Bs were built until 1967. As a derivative, the 720 had low development costs, allowing profitability despite relatively few sales. Compared to the 707-120, it has a length reduced by 8.33 feet (2.54 m), a modified wing and a lightened airframe for a lower maximum takeoff weight. Originally designed to be powered by four Pratt & Whitney JT3C turbojets, the initial 720 could cover a range with 131 passengers in two classes. The reconfigured 720B, powered by JT3D turbofans, first flew on October 6, 1960, and entered service in March 1961. It could seat 156 passengers in one class over a range. Some 720s were later ...
