夢想飛機787有多夢幻

The Boeing 787, famously known as the “Dreamliner”, is Boeing's latest effort to build an ultra-eff i cient aircraft. The blue and white jet with a sharklike streamlined design is a mix of art, technology and supreme quality infused with the modern concept of “green fl ight”. It is perfectly fi t for both point-to-point domestic fl ights and international long-distance fl ights.

以藍、白為主色調(diào)，擁有鯊魚般的流線型，它集藝術(shù)、科技、優(yōu)質(zhì)體驗于一身，融合現(xiàn)代綠色飛行理念，波音公司傾力打造的最新超高效率的飛機，既可用于點對點的國內(nèi)航線，也可用于長航距的國際航線，被航空界稱為“夢幻之翼”——它就是波音787。

Engines∶ the heart of power for the Dreamliner is not only 15% more fuel-efficient, but is also quieter – it is one of the world's quietest aircraft engines. Its larger, more efficient fan blades run at a fan tip speed 60% lower than those of aircraft of similar size.

787的動力心臟—發(fā)動機：不僅燃油效率提高了15%，還是目前世界上最安靜的發(fā)動機之一，其更大、效率更高的風扇葉片以較低的葉尖速度運轉(zhuǎn)，比現(xiàn)有類似尺寸的飛機要小60%以上。

Wings∶ The wingtips use a swept and integrated design, like a swallow tail, which helps improve their aerodynamic performance at high sub-sonic speeds and enhance the wings' flight efficiency.

機翼翼梢采用斜削式設(shè)計，像燕子的尾巴，翼梢尖尖的，這種一體成型的斜削式的翼梢在高亞音速飛行時會具有更好的氣動性能，有利于提升機翼的飛行效率。

FASTEST CIVIL PASSENGER AIRCRAFT

夢幻之一：最快的民用飛機

The overall airframe, main wings and control surfaces of the Boeing 787 are all made of carbon fi bre composite materials, which have the advantages of corrosion resistance, are lightweight, great strength and ease of design. Meanwhile, the wings have a much lighter weight, greater torsional strength and more powerful climbing ability than conventional wings.

ENVIRONMENTALLY-FRIENDLY AND FUEL-EFFICIENT

夢幻之二：環(huán)保節(jié)能

The Dreamliner is 20% more fuel-eff i cient than similar aircraft, emitting fewer greenhouse gases. It also creates 60% less noise than other aircraft during takeoff and landing. In addition, its cabin is equipped with better air fi lters, ensuring better cabin air quality. The aircraft is also more durable, with the repair frequency reduced by 30%.

COMPLETE COMPUTER CONTROLS

夢幻之三：全面計算機控制

The Boeing 787 is currently the only aircraft model that completely shifts to a fl y-by-wire control system. The use of electric signals transmitted by wires enables fl ight control computers to quickly determine how to properly move the actuators at each control surface to provide the ordered response, thus reducing human error by pilots and improving fl ight safety. In addition, the braking system of 787's landing gear is also electric – the only type of its kind. Electric brakes do not have the disadvantage of oil leakage as the electronic control of landing gear by computers enhances the accuracy of braking and reduces the parts replacement rate.

IMPROVED COMFORT

夢幻之四：更舒適

Thanks to the greater strength of composite materials, Boeing 787's cabin altitude can be adjusted lower while the pressure altitude remains higher, allowing more air inside the cabin. Humidity levels in the cabin can also be higher because composite materials do not corrode like metals. Thus, passengers are not prone to feel dry and tired during long-haul fl ights.
