瑞士太陽(yáng)能飛機(jī)開(kāi)始環(huán)球飛行

A solar-powered Swiss airplane took off from AbuDhabi early Monday on the first leg of what itscreators hope will be the first around-the-worldjourney without any fuel.

瑞士制造的一架太陽(yáng)能飛機(jī)星期一清晨從阿布扎比起飛。制造者們希望這架飛機(jī)能夠首次完成無(wú)燃料環(huán)球飛行。

The carbon fiber single-seater Solar Impulse 2aircraft has a 72-meter wingspan, which is longerthan the wingspan of a Boeing 747, and weighsabout as much as a car. The 17,000 solar cells builtinto the wings harness the sun's energy, allowing itto fly through the night.

用碳纖維材料制造的單人座“太陽(yáng)能動(dòng)力2號(hào)”翼展為72米，超過(guò)波音747，重量則僅相當(dāng)于一輛汽車(chē)。安裝在機(jī)翼上的1萬(wàn)7千個(gè)太陽(yáng)能電池儲(chǔ)存能量，以供夜間飛行。

The Si2 took 12 years to build and is the brainchild of two Swiss scientists - Bertrand Piccardand Andre Borschberg.

制造“太陽(yáng)能動(dòng)力2號(hào)”費(fèi)時(shí)12年。設(shè)計(jì)者是瑞士科學(xué)家皮卡德和博奇伯格。
