‘Round the Word Flight Delayed NEWS<br />
AEROSPACE<br />
Solar Impulse 2 grounded in Hawaii until 2016<br />
Solar Impulse (Lausanne, Switzerland)<br />
reported in the wake of the Solar Impulse 2’s<br />
(Si2) historic flight from Nagoya Japan to<br />
Hawaii on July 15 that damage to the plane’s<br />
batteries due to overheating during the<br />
record-breaking ocean crossing will require<br />
repairs that will keep the composites-intensive,<br />
solar-powered airplane, and copilots<br />
Bertrand Piccard and André Borschberg, in<br />
Hawaii until early spring 2016.<br />
Although the airplane performed very well<br />
during the five-day, five-night (117-hour, 52-<br />
minute) flight, unanticipated temperature<br />
increases occurred in the batteries during<br />
daily, planned quick ascents to and descents<br />
from 8,535m altitudes in the tropical climate,<br />
due to the high climb rate and an over<br />
insulation of the gondolas that contain the<br />
batteries.<br />
Repairs reportedly will take several months. In parallel,<br />
the Solar Impulse engineering team will study options for<br />
better cooling and heating processes on long flights. The<br />
round-the-world mission is expected to resume in early<br />

April 2016. Si2 will depart for the US West Coast, stopping<br />
in Arizona, then, crossing the US to New York City before<br />
making the Atlantic crossing to Europe and then returning<br />
to its point of departure in Abu Dhabi.<br />
