Solar Impulse grounded for 2-3 weeks 솔라 임펄스 항공기는 2-3주간 정비 위해 하와이에 머물러 있게 된다



Solar Impulse uses four lithium-ion battery units


The record-breaking Solar Impulse plane will be grounded in Hawaii for at least two weeks because of battery damage. 기록 경신 중인 솔라 임펄스 비행기는 밧데리 고장으로 당분간 최소한 2주간 하와이에 머물 것이다. 

The solar-powered vehicle overheated its electrical storage units during the historic, five-day crossing from Japan.

Engineers are trying to fix the plane but are not sure yet if new parts will be needed to get it back up into the air again.

The delay makes it less likely that Solar Impulse will complete its round-the-world quest this year.

Solar Impulse will not be allowed back in the air until it is completely ready

It set off from Abu Dhabi, UAE, in March with the intention of returning within five or six months.

But uncooperative weather along the route has added weeks to the original schedule.

If Solar Impulse cannot get to the US East Coast soon, the project team may find that the correct meteorological conditions for an Atlantic crossing are no longer available in 2015.

The vehicle's slow speed, light weight and 72m wingspan put significant constraints on the type of weather it can handle. And beyond August, the windows of opportunity to cross the second biggest ocean on Earth become few and far between.

Solo feat 일인(이 이룬) 위업

Pilot Andre Borschberg smashed aviation records when he steered Solar Impulse from Nagoya to Kalaeloa at the beginning of the month. 비행사 안드레 보쉬버그는 그 달초 나고야에서 칼레로아까지 솔라 임펄스의 조종간을 잡음으로써 (그 동안의) 비행기록을 깨버렸다.

Flying just on the power of the Sun, he completed the 7,200km in 118 hours. 태양의 힘에 의존해 비행하면서, 그는 118일 동안 7,200키로를 비행했다.

Not only did this set several new marks for manned solar aeroplanes, but it surpassed with ease the absolute aviation record for the longest solo flight in an un-refuelled vehicle. 이는 유인 태양동력 비행기로서 새로운 이정표였을 뿐만 아니라, 무동력 항공기로 최장시간의 단독비행을 한 기존의 비행기록을 쉽게 뛰어넘었다.

However, in achieving this mammoth feat, Mr Borschberg's plane experienced damaging overheating in its lithium-ion battery system. Although the units performed as expected, they had too much insulation around them, making temperature management very difficult. 이런 엄청난 위업(업적)을 성취함에 있어, 보쉬버그의 비행기는 리튬이온 전지 체계가 과열되는 손상ㅇ르 입었다.

The Solar Impulse team says it will issue another bulletin in the next few days when engineers have had time to assess the problems. If new parts are needed, it is not certain they will immediately be available.

Mr Borschberg and his partner on the project, Bertrand Piccard, have used their time in Hawaii to further spread their message on the importance of clean technologies.

It is Mr Piccard who is due to fly the next leg of the round-the-world mission, from Kalaeloa to Phoenix, Arizona.
