Boeing will not build a replacement for all new aircraft in the world’s most popular. Instead, the manufacturer decided to upgrade the 737 everywhere with a new engine and some other items to improve efficiency and prolong the life of more than 40 years old design.
The decision to “go back machine” of 737, rather than come up with a clean sheet design was done after the flight has made it clear they want fuel economy now rather than later. With the recent history of the all new 787 Dreamliner, there is concern in the industry as a new design can take more than a decade. Boeing promises to deliver 737 MAX as it was called in 2017.
Boeing says 737 MAX family of aircraft – there are three sizes – will be 10 to 12 percent less fuel than the current range of 737. And he said that it would be four percent more fuel efficient than A320neo.
First opened in 1968, the jet 737 is the most popular in the world. More than 6800 have been delivered and the company has a backlog of more than 2000.
Even with the new 787, most of the efficiency gains made by machine. Airlines may have won a few percent more than a replacement for the 737, but using existing cell also offers advantages.
Stay with the familiar design, the new aircraft will fit in flight and maintain the existing operating system. Even the cockpit would be left alone. Small improvement is possible, but not a major makeover is planned to keep familiar with the many existing drivers 737 and minimize the time for additional training.
The 737 MAX will win almost all the new improvements in engine efficiency. But the addition of new engines of the plane is a big challenge because of the limited space available under the wings.
The current model 737 has a flat cover at the bottom of the machine to keep the engine high enough on the ground. Modern hi-cut engine jet has a diameter substantially larger than the original engine offered on the 737 in the late 1960s.
