第45期 Boeing 787 28/04/2019

I think the Boeing 787 's wing tip is the best in all types of planes. The raked wingtip could avoid most of the air drag and provide extra airlifting power that make Boeing 787 become a type of aircraft that increase the distance of the flight and decrease the usage of fuel. Well, we can't add all the contribution to the wingtip, don't we? The engines GENX（General Electric Next-generation X)are also amazing.

As we knew that, if you want to make more money by selling products like an aircraft engine, you need to make the operating cost cheap and excellent capability as well. GENX has done that perfectly. The special shape of the fan, advanced aerostatic press technology and less pollution of carbon dioxide, what a star! More importantly, the eggshell fairing and application of serrated nozzle on the engine can reduce the noise and the power loss and provide passengers a lovely journey

Another good thing about Boeing 787 is it is really light compared to others and that's all because of the usage of the composite materials. Boeing 787 uses a large number of advanced composite materials. One of the most striking points is that the Boeing 787 uses around half of the body structure with a lighter, stronger composite material instead of aluminum alloy. For another reason, because the metal can hide damage problems, the damages are hard to find, until the fracture was found, but composite materials don't have this kind of question and also, it makes the plane very light so the engine could save more fuel and carry more passenger.

So, I think that's it. If you have any questions, please write it down in the Comment area below.

Thanks a lot.
