Boeing 747

With the increasing demand for air transport in the sixties approached the American Boeing company the Lord to draw on her new machine, which would be more than twice the current leading model of the 707th So brush up on earlier plans to designers for large military aircraft (the contract was ultimately their say-so) and is transformed to civilian aircraft.

History

The production program started in 1966 and in January 1970 was the first aircraft deployed to commercial operation. So Boeing had to develop ground-breaking machine just four years. During one such as he had in the city of Everett, near Seattle to build a new construction hall in which the first model of the 747-100, if unusual in their size, could enter. The plant is spread across an area of 300 hectares.

747 hidden in his belly three decks. The upper floor, which extends only through the torso, the lower floor and cargo area. Tradition, dealt with the location of the cockpit, which is located in a separate projection of the nose of the airplane. Since the beginning of rebuilding an envisaged potential for cargo aircraft and the cockpit has been designed out of his nose, which will thus be able odklápět, thereby facilitating cargo and interpretation.

Series -100, -200 and -300

The first model designation -100 The length 70 meters, height of 20 meters and a wingspan of 60 meters. His weight was 162 tons. To Flying nearly 10,000 km, has developed for him by Pratt & Whitney’s Special Motors. Later he began to use the Motors from General Electric and Rolls Royce. With them was to develop a prototype capable of speeds up to about 900 kilometers per hour. In dvoutřídovém design to fit to 452 passengers in three classes 266th

Hundred included in addition to the improved version 100b of the 747-100SR (short range), which was designed especially for short flights between the Japanese islands.

-200 Series gave a higher starting weight and longer range. The indisputable advantage of the ease of adjusting the aircraft from passenger to cargo or a combination of these two options. -200B has enjoyed stronger engine and-200C has undergone further improvements in terms of cargo transportation. One example was a hinged nose.

In 1983, the sky began to chase the Boeing 737-300. Its main feature was the extended upper deck and thereby also increased passenger capacity, which stopped at number 496 in dvoutřídovém design. -300 Series also included a model-300M and-300SP, again intended for domestic flights in Japan.

The most successful model of innovation and -400 747-8

Model 747-400 can boast the best-selling Boeing. The operation was launched in 1989 and its predecessor -300 has improved wings, more powerful Motors and better interior. Reaches a maximum range 13,500 km non-stop, and can fly at speeds up to 913 kilometers per hour. The board can accommodate up to 524 passengers.

Čtyřstovka been published in the-400F freighter, combined-400M, 400D, for short 400ER flights and on longer flights (there is also a cargo version).

Boeing 747-400 Production ended in December 2009 and has made room for the new model 747-8, the first prototypes are already in the world. New promises lower fuel consumption, improved fuel economy and should also be environmentally friendly.

When the sky will chase two versions. 747-8I are used to transport people is compared to its predecessor by three and a half feet long and holds and 34 more passengers. The distance should be closer to 15 aircraft thousands of miles, while its operating costs to be reduced.

Cargo version of the aircraft, identified as the 747-8F is about five and a half feet longer than the 747-400F, making it into the room for four more containers. Both types are equipped with the new austerity Motors GE, which have been developed for long-distance Boeing 787 Dreamliner. Version passengers in addition to attracting new interior, which he takes as a model model 777.

747 Unfortunately, decorated with yet another high numbers. He has to his credit dozens of accidents, including the most tragic in 1977 when it collided with each other at the start of two Boeing 747 Misfortune 583 people survived.
