The Vehicle 2009

There it is: Our "wind powered vehicle"
Here you can see the complete assembled car.





Guidelines
The organizer has put different framework conditions by which the most important ones shall be mentioned here.:

  1. Land transportation vehicle with wheels, controlled of a driver
  2. Propulsed by a device with spinning blades or turbine coupled to the wheels
  3. Temporary storage of energy is allowed during the ride (the storage device has to be empty at the start); the device will source and store it's power from a combination of wind and battery power solely during the course of the race
  4. Outside dimensions: length max. 4m, width: max. 2m
  5. Maximum rotor area 4m2
  6. Different system security features

 

Our Concept
The overall plan according to which our vehicle is built up is explained in the following:
The vehicle is made come true as a three-wheeled concept; the limit dimensions put by the organizer are made use of in the best possible way. A 3-wings horizontal rotor has been chosen for the "energy-extracting" device.
The energy required for the drive is taken from the wind by means of the rotor and transferred to a generator by the rotor. The generator feeds in the electrical power with the help of corresponding power electronics into the so-called DC-link circuit. The motor side converter is being powered from the DC-link and drives the propulsing motor drive. The flow of energy is controlled by a microcontroller.
