Boeing 747
The Boeing 747 is a long-range wide-body aircraft, wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the Boeing 707, 707 in October 1958, Pan Am wanted a jet times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the Boeing 737, 737 development program to design the 747. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft, and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan. On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant, the world's List of largest buildings#Largest usable volume, largest building by volume. The 747's first flight took place on February 9, 1969, and the 747 was certified in December of that year. It entered service with Pan Am on January 22, 1970. The 747 was the first airplane called a "Jumbo Jet" as the first wide-body airliner. The 747 is a four-engined jet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wide-body Aircraft
A wide-body aircraft, also known as a twin-aisle aircraft and in the largest cases as a jumbo jet, is an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The typical fuselage diameter is . In the typical wide-body economy cabin, passengers are seated seven to ten abreast, allowing a total capacity of 200 to 850 passengers. Seven-abreast aircraft typically seat 160 to 260 passengers, eight-abreast 250 to 380, nine- and ten-abreast 350 to 480. The largest wide-body aircraft are over wide, and can accommodate up to eleven passengers abreast in high-density configurations. By comparison, a typical narrow-body aircraft has a diameter of , with a single aisle, and seats between two and six people abreast. Wide-body aircraft were originally designed for a combination of efficiency and passenger comfort and to increase the amount of cargo space. However, airlines quickly gave in to economic factors, and reduced the extra passen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Four-engined Jet Aircraft
A four-engined jet, sometimes called a quadjet, is a jet aircraft powered by four Jet engine, engines. The presence of four engines offers increased power and redundancy, allowing such aircraft to be used as airliners, cargo aircraft, freighters, and military aircraft. Many of the first purpose-built jet airliners had four engines, among which stands the de Havilland Comet, the world's first commercial jetliner. In the decades following their introduction, their use has gradually declined due to a variety of factors, including the approval of Twinjet, twin-engine jets to fly farther from diversion airports as reliability increased, and an increased emphasis on fuel efficiency. Design Podded engines The engines of a 4-engined aircraft are most commonly found in Podded engine, pods hanging from pylons underneath the wings. This can be observed in the Airbus A340, Airbus A380, and Boeing 747. Many military airlifters also feature this design, including the Antonov An-124, Boein ...

Boeing 747SP
The Boeing 747SP (for ''Special Performance'') is a shortened version of the Boeing 747 wide-body airliner, designed for a longer range. It is the highest flying subsonic passenger airliner, with a service ceiling of . Boeing needed a smaller aircraft to compete with the McDonnell Douglas DC-10 and Lockheed L-1011 TriStar tri-jet wide-bodies, introduced in 1971/1972. Pan Am requested a 747-100 derivative to fly between New York and the Middle East, a request also shared by Iran Air, and the first order came from Pan Am in 1973. The variant first flew on July 4, 1975, was approved by the Federal Aviation Administration on February 4, 1976, and entered service that year with Pan Am. The SP is in length, shorter than the original 747 variants. Its main deck doors are reduced to four on each side to suit its lower capacity. The vertical and horizontal tailplanes are larger and its wing flaps have been simplified. With a maximum take-off weight, it can fly 276 passenge ...

List Of Largest Buildings
Buildings around the world listed by usable space (volume), footprint (area), and floor space (area) comprise single structures that are suitable for continuous human occupancy. There are, however, some Nonbuilding structure#Exceptions, exceptions, including factories and warehouses. The Tropical Islands Resort, Aerium near Berlin, Germany is the largest uninterrupted volume in the world, while Boeing Everett Factory, Boeing's factory in Everett, Washington, United States is the world's largest building by volume. The AvtoVAZ main assembly building in Tolyatti, Russia is the largest building in area footprint. The New Century Global Center in Chengdu, China is the largest building in terms of total floor area. Due to the incomplete nature of this list, buildings are not ranked.

Everett Plant
The Boeing Everett Factory, officially the Everett Production Facility, is an airplane assembly facility operated by Boeing in Everett, Washington, United States. It sits on the north side of Paine Field and includes the largest building in the world by volume at over , which covers . The entire complex covers approximately and spans both sides of State Route 526 (named the Boeing Freeway). The factory was built in 1967 for the Boeing 747 and has since been expanded several times to accommodate new airliners, including the 767, 777, and 787 programs.

High-bypass Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more jet thrust relative t ...

JT9D
The Pratt & Whitney JT9D engine was the first high bypass ratio jet engine to power a wide-body airliner. Its initial application was the Boeing 747-100, the original "Jumbo Jet". It was Pratt & Whitney's first high-bypass-ratio turbofan. Development 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. The enhanced JT9D-7R4 was introduced in September 1982 and was approved for 180-minute ETOPS for twinjets in June 1985. By 2020, the JT9D had flown more than 169 million hours. Production ceased in 1990, to be replaced by the new PW4000. The JT9D was developed from the STF200/JTF14 demonstrator engines. The JTF14 engine had been proposed for the C-5 Galaxy program but the production contract was awarded to the General Electric TF39. The e ...
