NUNA9 WINS THE BRIDGESTONE WORLD SOLAR CHALLENGE
This morning at 6.45 h. European time the solar car Nuna9 passed the finish line in Adelaide in pole position during the Bridgestone World Solar Challenge 2017. The Nuon Solar Team took four days and six hours for the 3,000 kilometer race from Darwin to Adelaide. Aliancys is the innovation partner of the Nuon Solar Team. The construction and outer shell of the Nuna9 have been manufactured with styrene-free Beyone™ resins from Aliancys.
COPING WITH THE WIND
On the first racing day, weather conditions were pretty good with plenty of solar radiation to catch. The Nuna9 has a relatively small surface of (high efficiency) solar cells. This allowed making the car significantly smaller and lighter than the cars made for previous editions. But after a windy racing day on Tuesday and a night with heavy rains, yesterday the team had to cope with stormy weather. Wind speeds exceeded 60 kilometers per hour, while the sky was often covered with heavy clouds. Driver Emma Vercoulen tells: "Because of the strong wind it was not easy to keep the Nuna on the road and follow a perfect line. I felt the car was shaking under me, while I tried to avoid the rain puddles on the road. Pretty scary, but also very exciting!"
CHANGE OF STRATEGY
In order to ensure the Nuna driver is safe, the Nuon Solar Team decided to decrease speed where needed. In spite of this lower speed the team still managed to maintain its first position in the race. The students contribute this to a large extent to their strategy. Strategist Stijn Burger was working with his laptop in Mission Control, the car behind the Nuna "In Mission Control we keep a close watch on the car condition and the actual weather. Today we have especially monitored the wind as well as the clouds above the road. By driving slightly slower when there is sunshine, the Nuna can capture more sunlight. Then, when there is a cloud the Nuna can speed up and get through quickly.”
