Shortly after the presentation of the solar car of the Twente team has the Nuon Solar Team are new Nuna6 is presented to the public. The all-new solar car of the Delft team is more compact and lighter than its predecessor.
The Nuna6 has a length of 4,44 m and is therefore the most compact car that the Nuon Solar Team has built since his first vehicle in 2001. Also is the weight to be further reduced; the vehicle weighs 145kg and is 35kg lighter than the 21Connect, the Solar Team Twente.
In the design of Nuna6 has the Delft team again opted for a wing profile. According to the Nuon Solar Team, this is a proven design and has the aerodynamic shape proven in the wind tunnel. Compared to the Nuna5 would the drag of the three-wheeled vehicle with 10 percent.
Both the chassis if the topshell is made of foam and carbon fiber textreme. This material is, among others, in the Formula 1 is applied. A number of parts in addition with aramid reinforced to gravel and the driver to protect it. By the way, the driver is also protected by a titanium roll bar.
The Nuna6 is powered by a CSIRO InWheel Direct Drive electric motor. This is in the rim of the rear wheel and would have an efficiency of 98 percent. The 21kg weight of batteries, with a capacity of 5kWh, are powered by a total of 1690 monocrystalline solar cells, which have a surface area of 6m2 on the car are divided. According to the Nuon Solar Team know the panels an efficiency of 22 percent to achieve.
The Nuon Solar Team, consisting of thirteen students from the TU Delft, will travel in August to Australia to again take part in the World Solar Challenge. In the last race in 2009, finished the team with silver, but the team did this four times gold to tackle. The members are confident that they will with the Nuna6 is again a good chance in the first place. Also, the Nuon Solar Team that the designs of the competing solar cars becoming more like the Delft Nuna. From this it would appear that this is the most successful design.
