The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2 + 1 ⁄ 2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design ...
The Boeing 747-400 is a large, long-range wide-body airliner produced by Boeing Commercial Airplanes, an advanced variant of the initial Boeing 747.The "Advanced Series 300" was announced at the September 1984 Farnborough Airshow, targeting a 10% cost reduction with more efficient engines and 1,000 nautical miles [nmi] (1,900 km; 1,200 mi) of additional range.
However, some of the engineering work on the 747SP was reused with the development of the 747-300. In the 747SP, the upper deck begins over the section of fuselage that contains the wing box, not ahead of the wing box (as is the case with the 747-100 and 747-200). This same design was used in the 747-300 and newer 747-400, resulting in a ...
The 747-8 was the first lengthened 747 to go into production and the second 747 version with a fuselage of modified length after the shortened 747SP. The 747-8 was intended to use the same engine and cockpit technology as that of the 787, including the General Electric GEnx turbofan and fly-by-wire ailerons and spoilers. [ 11 ]
The JT9D program was launched in September 1965 and the first engine was tested in December 1966. It received its FAA certification in May 1969 and entered service in January 1970 on the Boeing 747. It subsequently powered the Boeing 767, Airbus A300 and Airbus A310, and McDonnell Douglas DC-10.
This convention was followed in the development of the newest version of the 747, the 747-8, along with the 737 MAX and 777X series. Additional letters are sometimes appended to the model name as a suffix, including "ER" to designate an "extended range" version, such as the 777-300ER , or "LR" to designate a "long range" version, for example ...
