B 747 200 Air France 3D model on Flatpyramid.
The Boeing 747 3D model commonly dubbed "Jumbo," is a wide-body transcontinental commercial aircraft manufactured by Boeing. It is known for its large size (it was the largest passenger plane for more than three decades until the Airbus company created the A380 ) and is among the most famous aircraft in the world. He made his first commercial flight in 1970 and was the first aircraft with a wide fuselage.
The four 747 turbofan engines are manufactured by Pratt & Whitney. The JT-9D engine was released with that plane and has been used later by other wide-body aircraft, such as the Douglas DC-10. His two-story cabin has given him much recognition in the air transport sector. With a typical distribution of three classes of passengers, it carries 416 people, while a two-class arrangement can accommodate a maximum of 529 passengers. The 747-8, the most recent version in service, flies at subsonic speeds of Mach 0.85 (about 913 kilometers per hour ) and offers an intercontinental flight range of 8,000.nautical miles (15,000 kilometers ).
It was predicted that the 747 would be obsolete when the first 400 units had been sold, but the model has exceeded all expectations and, after those criticisms, production reached 1,000 units in 1993. By December 2017, 1542 aircraft had been built, with another 12 units of the 747-8F variant waiting to be delivered. 12 The most recent version of this model, the 747-8, entered service with Cargolux (cargo version) on October 12, 2011, and with Lufthansa (passenger version) on June 1, 2012.
The 747 is one of the most recognizable aircraft by the public. The aircraft was called the "Queen of Heaven" ( Queen of the Skies ). It has been used by millions of people to carry out international flights. In addition, it was the first civil wide-body aircraft, the largest, the heaviest and the pioneer in the use of turbofan engines of high derivation ratio, less polluting and noisy than conventional turbojets.
